Le funzionalità per implementare una solida infrastruttura wireless nelle scuole

Piano Scuola per accelerare la realizzazione di reti WiFi nelle scuole

Piano Scuola è il fondo istituito a livello nazionale, per velocizzare l’installazione e la digitalizzazione dell’infrastruttura IT delle scuole.

Attualmente, l’Italia vede un forte divario rispetto agli altri Paesi europei, soprattutto in termini di diffusione dell’utilizzo di reti WiFi. Il programma è stato avviato proprio con l’intento di colmare definitivamente questo gap.

Sono stati infatti stanziati oltre 400 milioni di euro per la realizzazione di una rete Internet adeguata negli istituti scolastici di tutto il territorio nazionale, potenziando la connettività grazie alla banda ultralarga.
La velocità di connessione negli edifici raggiungerà 1 Gbps con 100 Mbps di banda garantita, per un totale di 32.213 plessi scolastici. I costi copriranno le spese strutturali e la connettività per la durata di 5 anni.

Funzionalità da considerare nelle reti WiFi scolastiche

Gli operatori dovranno tenere in considerazione alcune funzionalità fondamentali per una corretta progettazione, pianificazione e implementazione di reti wireless in situazioni ad alta densità, come le scuole. 

Cloud pubblico

Quando si parla di implementazioni di reti WiFi nelle scuole, il cloud pubblico rappresenta l’opzione migliore per gestire soluzioni di sicurezza wireless dal cloud. Il cloud pubblico offre un’infrastruttura potente e le applicazioni più adatte a semplificare la gestione della rete e la sua sicurezza.

Inoltre, il public cloud consente di scalare senza limiti e senza interruzioni, e riduce il TCO, ovvero il calcolo di tutti i costi del ciclo di vita di un’apparecchiatura informatica IT, per l’acquisto, l’installazione, la gestione, la manutenzione e il suo smaltimento.

Monitoraggio da remoto

Il monitoraggio da remoto elimina la necessità per gli operatori IT di di essere fisicamente presenti sul posto per verificare lo stato della rete.
La possibilità di monitorare in remoto consente agli operatori di controllare ogni parte della rete da qualsiasi luogo e di essere avvisati tempestivamente dei problemi che interessano tutte le aree della rete, come indicatori di prestazione della rete WiFi e statistiche in tempo reale, sia a livello di rete WiFi sia a livello di access point.
Ogni access point parla individualmente con il cloud, non ci sono single point of failure che si avrebbero invece con controller, e di fatto l’impianto è modulabile come si preferisce, visto che la comunicazione col cloud è diretta tra cloud stesso e access point.

Web content filtering

Per garantire una maggiore sicurezza della rete, è importante tutelare con i giusti meccanismi di crittografia l’ambiente Internet nelle scuole, più facilmente esposto a rischi. Creare, dunque, una policy granulare per garantire che gli studenti siano protetti da siti web dannosi e non affidabili diventa essenziale nella progettazione di reti all’interno degli ambienti educativi.

Il Web content filtering consente proprio di configurare un sistema di filtro dei contenuti su tutta la rete, in modo da garantire una navigazione sicura per gli utenti. Grazie a questo strumento, la scuola può bloccare la navigazione di siti web inappropriati, ad esempio, contenuti pornografici, siti di scommesse e siti di malware.

WiFi nelle scuole – La situazione nel settore dell’istruzione

WiFi nelle scuole

WiFi nelle scuole – La situazione nel settore dell’istruzione

Negli ultimi anni, abbiamo assistito a una rapida diffusione della tecnologia WiFi nelle scuole. Negli istituti scolastici si registra un uso crescente di dispositivi connessi a Internet a supporto della didattica e dei servizi a studenti e docenti. Lo studente medio possiede almeno tre dispositivi che utilizzano WiFi. Una rete WiFi solida e affidabile diventa, perciò, un requisito imprescindibile, soprattutto in un momento come questo, in cui la prospettiva di dover fruire di lezioni online sta diventando sempre più una certezza.

Utilizzo delle reti WiFi nelle scuole

Le reti WiFi rappresentano un mezzo fondamentale per facilitare l’uso dei servizi di networking disponibili all’interno di tutti gli ambienti scolastici e delle aree dedicate alla didattica.

La connessione WiFi facilita l’accesso immediato e illimitato a una moltitudine di risorse online da qualsiasi luogo della scuola. In questo modo, gli insegnanti possono incoraggiare un apprendimento indipendente e autonomo tra gli studenti, sviluppando allo stesso tempo metodi di insegnamento sempre più creativi e interattivi. Inoltre, il WiFi nelle scuole aiuta a monitorare istantaneamente i progressi degli studenti stessi e a intervenire per assisterli sul momento quando necessario.

L’utilizzo di Internet tramite WiFi offre alle scuole e agli insegnanti il potenziale per un valido cambiamento nei metodi di insegnamento tradizionali, fornendo un ambiente di apprendimento più moderno per gli studenti. Ancor di più, se si considera che il WiFi assume importanza vitale, non solo all’interno delle classi, ma anche al di fuori, nelle aree sociali, in biblioteca e in tutti gli ambienti scolastici, dove gli alunni possono essere incoraggiati ad apprendere in un contesto più autonomo.

Una ricerca dell’Università di Oxford sottolinea come, nonostante la maggior parte degli studenti ne sia provvisto, in molti ancora non possiedono dispositivi personali o una rete Internet a casa. Motivo per cui questi studenti, ancora al giorno d’oggi, risultano svantaggiati da un punto di vista accademico. Lo studio mette in evidenza come l’educazione andrebbe erogata in modi più moderni ed evoluti, al fine di sostenere l’interesse e incoraggiare l’impegno interattivo degli alunni. Di conseguenza, la presenza di una rete WiFi nelle scuole diventa di primaria importanza.

Cosa richiedono le scuole?

Anche se le reti installate negli ambienti scolastici devono soddisfare requisiti alti in termini di dispositivi multipli, strumenti online, aule virtuali e una grande quantità di client, molti istituti non dispongono di personale IT dedicato, hanno budget limitati e dipendenti non tecnici. Pertanto, le soluzioni wireless proposte alle scuole devono venire incontro alle particolari esigenze del settore, risolvendo le sfide specifiche che una scuola si trova ad affrontare. I fornitori di rete, oltre alle funzionalità di base, dovranno offrire un WiFi affidabile e ad alta velocità, semplicità di installazione e di configurazione, e la capacità di gestire in maniera efficiente anche un numero elevato di client connessi simultaneamente.

La situazione italiana

Il nostro Paese parte da una situazione svantaggiata che ci vede sotto la media europea nella diffusione dell’infrastruttura necessaria all’utilizzo di reti WiFi. Il Governo si è assunto un impegno forte e deciso, definendo una strategia che dovrà essere periodicamente aggiornata adeguandosi all’evoluzione delle tecnologie, dei servizi e della domanda.

Il settore pubblico, in questo caso, è rappresentato dal Comitato per la diffusione della Banda Ultralarga (COBUL) che ha definito la strategia attuale e ne monitorerà la corretta esecuzione.

Perché è necessaria la banda ultralarga?

La banda ultralarga sarà l’infrastruttura portante dell’intero sistema economico e sociale su cui investire. L’Italia è indietro rispetto alle colleghe europee per quanto riguarda digitalizzazione e diffusione della banda ultralarga. Risulta quindi più che urgente, dotare il Paese di reti a banda ultralarga e accelerare così il processo volto alla digitalizzazione.

Con il Piano Strategico Banda Ultralarga, in corso in oltre 650 comuni, l’Italia ha elaborato una strategia nazionale che definisce i principi base delle iniziative pubbliche a sostegno dello sviluppo della banda ultralarga per garantire un corretto utilizzo dei fondi pubblici, riducendo così anche il peso amministrativo di regioni e comuni. 

L’obiettivo del piano strategico è quello di rimediare a questo divario infrastrutturale e di mercato, concentrandosi in particolare sulla realizzazione delle reti a 100 Mbps, il risultato più difficile da raggiungere per gli operatori di mercato.

Piano Scuola

In questo contesto, si fa strada il Piano Scuola, programma promosso per dare un sostegno alla digitalizzazione nelle scuole. Per il progetto sono stati stanziati oltre 400 milioni di euro come fondi destinati alla connessione alla rete Internet degli istituti scolastici su tutto il territorio nazionale, potenziando la connettività grazie alla banda ultralarga. 

La velocità di connessione negli edifici raggiungerà 1 Gbps con 100 Mbps di banda garantita, per un totale di 32.213 plessi scolastici. I costi copriranno le spese strutturali e la connettività per la durata di 5 anni.

Gli operatori che saranno coinvolti nel progetto, dovranno muoversi d’anticipo e considerare una vasta gamma di fattori che andranno valutati in ambienti come le scuole, dove è necessario connettere contemporaneamente diversi dispositivi client, che caricano/scaricano e trasmettono contenuti in streaming. 

Quali sono le best practice da seguire nell’implementazione di reti WiFi per le scuole?

Per una corretta implementazione WiFi nelle scuole, è consigliabile seguire una serie di accortezze, in modo da non farsi trovare impreparati.

Ad esempio, uno dei primi passi da compiere riguarda la verifica della larghezza di banda. Infatti, quest’ultima deve essere sufficiente a supportare access point con capacità di trasmissione elevata, utilizzando switch POE per alimentare direttamente gli access point, rispettivamente da 1-10 Gbit al punto di aggregazione di tutto il traffico, e da 1 Gbit per gli switch periferici.

Sarebbe poi necessario effettuare un controllo sul posto per identificare e risolvere eventuali problemi di potenziali forme di interferenza, e prima dell’implementazione, provare a caricare completamente la rete per assicurarsi che l’impianto sia effettivamente in grado di gestire efficacemente tutto il traffico generato.

Cos’è il Piano Scuola?

Piano Scuola è il programma avviato dal Comitato per la diffusione della Banda Ultralarga (composto dalla Presidenza del Consiglio dei Ministri, dal Ministero dello Sviluppo Economico, da Infratel e AgID – Agenzia per l’Italia Digitale), per cui sono stati stanziati oltre 400 milioni di euro come fondi destinati al cablaggio dei plessi scolastici su tutto il territorio nazionale.

Quale obiettivo intende raggiungere il Piano Scuola?

L’obiettivo del Piano è quello di potenziare la connettività delle scuole, portando negli istituti la banda ultralarga, con una velocità di connessione negli edifici che raggiunga 1 Gbps con 100 Mbps di banda garantita, per un totale di 32.213 plessi scolastici.

L’81,4 % degli istituti scolastici potrà essere dotato dell’infrastruttura necessaria per avere una connettività veloce. Attraverso i fondi delle Regioni e altre economie di spesa si punterà poi a raggiungere progressivamente il 100% degli edifici scolastici. In particolare, il piano prevede il collegamento di tutti i plessi scolastici delle scuole medie e superiori sul territorio nazionale e, nelle “aree bianche”, anche il collegamento di tutti i plessi delle scuole primarie e dell’infanzia.

Come si articola la realizzazione del Piano?

Il Comitato Banda Ultra Larga, COBUL, ha presentato il 5 maggio 2020 un piano globale che coinvolgerà Famiglie, Piccole e Medie Imprese, Scuole, in tutte le aree del Paese, e il Ministero dello Sviluppo Economico ha affidato con decreto ad Infratel Italia le risorse per avviarne la realizzazione.

Alcune regioni potranno realizzare il progetto in autonomia (Emilia Romagna, Friuli, Provincia di Trento e Umbria) o parzialmente in autonomia (Sardegna, Liguria). Le altre regioni e province saranno coordinate nella realizzazione dei lavori da Infratel Italia che, ricevuto il mandato a seguito del DM di affidamento dal Ministero dello Sviluppo Economico, pubblicherà il relativo bando, da avviare nel mese di giugno, con aggiudicazione e firma del contratto entro settembre 2020. Oggetto dell’affidamento sarà la fornitura della fibra di accesso e del servizio di trasporto e di connettività per le sedi scolastiche, in modo da dotarle di accesso Internet.

A giugno 2020 vengono presentati i primi bandi e già a settembre si partirà con le installazioni, i cui lavori si prolungheranno fino al mese di ottobre.

Infratel Italia procederà con la creazione di una piattaforma per operatori e Service Provider attraverso cui sarà possibile applicare. La piattaforma è in fase di progettazione da parte di Invitalia e sarà disponibile non prima del 30 giugno 2020. Per restare aggiornati, si prega di visitare il sito bandaultralarga.italia.it.

 

La tempistica prevede:

Interconnessione immediata di 29.000 plessi
– entro giugno 2020: avvio del bando
– entro metà settembre 2020: aggiudicazione contratto
– entro ottobre 2020: avvio deployment

Interconnessione di ulteriori 2.800 plessi che hanno bisogno di posa della fibra
– da metà maggio a metà agosto: consultazione operatori e Notifica CE
– entro fine settembre 2020: approvazione della Commissione

A cosa serviranno i fondi stanziati?

I 400.430.897 euro del Piano Scuola saranno utilizzati per coprire i costi strutturali della banda ultralarga nelle istituzioni scolastiche e i costi di connettività per la durata di 5 anni, con inclusa la manutenzione delle reti, che saranno garantiti in maniera gratuita.
Il progetto Piano Scuola che prevede misure immediate volte alla digitalizzazione degli istituti scolastici, è diventato di primaria importanza. In particolare, nell’epoca post Covid, in cui le infrastrutture e la fornitura digitale fino a questo momento disponibili, si sono rivelate totalmente insufficienti e non in grado di assicurare la presenza di una connettività adeguata. I fondi richiesti dal CoBUL consentiranno finalmente, in tempi rapidissimi, l’accesso alle reti ultraveloci nelle scuole di tutta Italia.

Public Cloud vs Hybrid Cloud vs Private Cloud – What is the best choice?

Public Cloud vs Hybrid Cloud vs Private Cloud
Public Cloud vs Hybrid Cloud vs Private Cloud – What is the best choice?

Public cloud vs Hybrid cloud vs Private Cloud: the debate around cloud environments has long been argued in the IT industry. Why should you consider Public Cloud instead of Hybrid or Private Cloud? What are the benefits of each of them? Which one is the best alternative?
The choice between Public, Private, and Hybrid Cloud solutions depends on a variety of factors. By recognizing the similarities and differences, you can be more informed about how each cloud computing type might impact your business.

Cloud Computing represents the alternative to the on-premises traditional data center, as IT services are delivered across the Internet. The cloud environment provides an easily accessible online portal that makes it suitable for the user to manage the compute, storage, network, and application resources.

Cloud computing, in general, reduces the cost and complexity of your business IT infrastructure handling. The main benefits of the cloud concern: 

  • Cost: the considerable capital costs (CAPEX) can be drastically reduced, and the Total cost of ownership (TCO) can be easily monitored.
  • Speed: resources can be accessed faster.
  • Scalability: the requirement of resources can be increased or decreased according to business needs.
  • Productivity: while using cloud computing, there is less need to put efforts in applying and maintaining hardware and software. In this way, the IT team can be focused on reaching business goals and be more productive.
  • Reliability: back-up and recovery of data is less expensive and quick.
  • Security: a large set of policies, technologies, and controls can extend your business security.

Cloud computing in the WiFi industry

Cloud computing has been discussed in the WiFi industry, because, like other divisions of computing, it offers highly scalable capabilities that are difficult or expensive to deliver on-site, with the opportunity to also provide granular services on a micro-scale.

Cloud networks afford a deployment model for remote sites and remote employees, where IT staff resources are inadequate. Cloud management can be accessed from anywhere, distributed or centralized IT teams can easily manage and monitor distributed sites.

The most consistent benefit to cloud networking is that a business of any size can have access to an enterprise-class wireless solution that prevents IT staff from being overwhelmed or IT budget to be wrecked.

Indeed, one of the most demanding debates across businesses looking for IT solutions has been whether to implement a WLAN managed with on-premises controllers, or one with controllers in the cloud, as the most suitable architecture.

Dating back to the early beginning of WLAN history, each wireless access point was configured and managed separately from one another. This way to proceed was reasonable at the time because access points were deployed in specific areas, and the number of devices connecting to WiFi networks was slim.

Today WiFi is increasingly gaining business favour, thanks to cost-effective efficiency. But, owning and managing a WiFi infrastructure solution takes noticeable time and capital investment. Cloud computing is successfully reaching traction for a lot of business applications. Therefore, many WiFi infrastructure vendors have started looking towards cloud architecture from the WiFi perspective to launch WiFi infrastructure solutions as cloud-based services.

In fact, with the rapid evolution and growing complexity of the WLAN, it is becoming more painful and expensive for companies to staff in-house WiFi expertise. So organizations are increasingly relying on the experience of Managed Solution Providers (MSPs) to fill this divide. If MSPs optimize the cloud solution, it can make the business model much more effective, mainly because of easy-to-access remote management, monitoring, reporting, and troubleshooting.

Types of Cloud Computing

Cloud computing covers a range of categorizations and architecture models that can be classified into three main types:

 

  • Public Cloud is the cloud where the resources are owned and operated by a third-party cloud service provider and can be shared with other organizations. All the WiFi Access Points will connect directly to the Public Cloud infrastructure over the Internet, with no need to have any intermediary device such as a hardware controller. The management traffic is completely isolated from the users’ traffic and securely reaches the cloud infrastructure. The users’ traffic flows through and goes directly to the destination being invisible to the cloud infrastructure. As the same infrastructure serves multiple customers, there is an excellent economy of scale and the ability to provide services in a granular and cost-effective way.
  • Private Cloud brings the same services of the Public Cloud, but in a dedicated context exclusively used inside a single business or organization. The security offered by a Private Cloud model is suitable for any organization that needs to store and process private data or particularly sensitive tasks. However, setting up a Private Cloud may imply some set-up costs, and for this reason, Private Cloud usually requires some minimum scale to be economically viable.
  • Hybrid Cloud is a Cloud computing environment that uses a mixture of on-premises, Private Cloud, and Public Cloud services by using technology that allows data applications to be shared among them. The data can be stored locally on-premises in dedicated additional hardware while being accessible from remote.

How to choose a Cloud type or Cloud service is an individual decision. The cloud model you choose depends on which features you find most important and how much you want to invest. The more cost-effective Public Cloud is easy to manage and offers significant scalability and reliability at the same time. A Private Cloud instead gives more control to where the data is stored and keeps it more confined at a price of a higher set-up cost.

Usually, SMBs/SMEs are comfortable with Public Cloud solutions, as they can optimize their costs and leverage great flexibility. Instead, government projects may demand the Private Cloud approach for policy, to keep all data on specific servers dedicated to them, and located where they prefer. A Hybrid Cloud brings a blending of both worlds, by storing data on a device that is located on-premises, so not in the cloud, but allowing access from remote, via a cloud-portal that acts as a way to tunnel back to the on-premises device. This approach can have some advantages as well as limitations.

The Hybrid Cloud has limits

The Hybrid Cloud seems to show more flexibility, combining elements of the leading cloud model types. But it also demonstrates to have a series of disadvantages, especially when considering multiple access points (AP) locations.

  • Number of devices to be deployed: in general, the Hybrid Cloud model requires deploying an extra hardware device dedicated to storing data and enabling remote control. This implies a potential high impact on the number of devices to be deployed. For example, with a Public Cloud solution, 100 retail stores will require 100 APs, and those APs will directly connect to the Public Cloud infrastructure. On the contrary, the Hybrid Cloud solution applied to this scenario would need a hardware hybrid controller per each location to enable the connectivity from each AP to the Cloud. In this way, costs are generally highly-impacted.
  • Single point of failure: controller hardware devices, such as hardware controllers or cloud keys, represent a single point of failure. So the entire system is at risk when a single element fails, as the whole remote visibility and centralized configuration capabilities get disrupted.
  • Complex set-up: in a Hybrid Cloud system, you need to configure the cloud key, and associate it to the APs, then connect it to the cloud portal. The set-up could be, therefore, highly complicated. On the contrary, Public Cloud solutions allow to simply plug the units and see them auto-provisioning, as there is no intermediary device to be configured.
  • On-site IT staff: sometimes APs, cloud key, and cloud portal get disassociated for some reason, for instance, APs get reset to factory settings. This means that you will need to have someone on-site to restore all these associations.
  • Limited scalability: solutions based on cloud keys (and even higher-end enterprise hardware controllers) have an intrinsic scalability limitation as they can support a limited number of APs. Once that threshold is crossed, there is a need to change the hardware controller. On the other side, Public Cloud has unlimited scalability by definition.
  • Limited software flexibility: Hybrid Cloud solutions, keeping all the data on a local device, do not allow the flexibility of cloud solutions, which can literally connect any APs to third party systems. For example, Location Analytics systems can only be enabled if there is strong integration between the APs and cloud infrastructures via APIs.
  • Disaster recovery: Hybrid Cloud vendors are usually from the hardware industry and not service-oriented. Their business model is conceived to sell hardware, not necessarily to help users operate networks. On the contrary, the mission of a Public Cloud provider is to enable IT companies while they provide managed services. For example, if there is a disaster and all the devices reset due to an electric shock, a hybrid vendor’s support may state that you should have performed back-ups daily to recover from the disaster. On the other hand, a Public Cloud provider may assert that the disaster was managed precisely by the daily back-ups, performed as part of the service, so there is no need for any further action as they take care of everything. 

8 Reasons why should Public Cloud be your choice over Hybrid Cloud

  1. No single point of failure: the Public Cloud does not have a single point of failure. That means that even if one part fails, the entire system will not stop working.
  2. Simple set-up: the Public Cloud does not need an elaborate set-up. You don’t need to associate APs to the cloud key and the cloud key to the cloud account.
  3. No need to go on-site: with Public Cloud, network admins never need to go on-site to re-associate APs/key/cloud, which sometimes happens when a cloud key fails or gets reset.
  4. Zero-touch provisioning: Public Cloud provides zero-touch provisioning. With a Hybrid Cloud instead, APs do not connect automatically to the cloud and must be provisioned.
  5. Scalability: the Public Cloud has unlimited scalability. In the Hybrid Cloud, instead, some cloud keys support a maximum number of APs and sometimes have been reported to be slow in responding. 
  6. Cost: you do not need expensive controllers, that for locations with a low number of APs may represent an essential percentage of the total hardware investment.
  7. Software flexibility: Public Cloud is ready to integrate with unlimited third-party systems and applications that can deliver the exact features you need, from location analytics to marketing services to IoT.
  8. You are not on your own: in case of disaster, you can rely on a team of professionals whose goal is to enable your operations and keep them up-and-running, no matter what.

What will happen next?

Newly developed technologies push controllers forward, and reached the cloud environments in recent years. In a cloud-managed WLAN architecture, organizations don’t have to purchase physical controllers and deploy them on every site. The cloud works like a virtual controller that resides in a Public Cloud, and all the distributed wireless access points connect to it via the Internet.

The cloud offers remote provisioning, monitoring, and troubleshooting to every access point.
The cloud-managed WLAN services rely on subscribed licenses to work, and the cloud will take care of the issues such as data back-up, storage, redundancy, and more. The service may be free, freemium, or subscription-based. Therefore, differently from the hardware controller with higher CAPEX cost, the cloud-managed WLAN services, which are usually provided with an annual payment plan, give businesses more adaptability on their budgets.

Companies are now discovering that the real benefit of cloud computing is not the cost savings it can bring, but the fact that IT can react much faster and more effectively to business changes. The value of great agility and time-to-market makes cloud computing a good move for any kind of organization.

Compared to on-premises solutions, Public Cloud services are getting more and more popular among organizations of different sectors, looking for centralized management and reduced costs.

Ping Tool – How to troubleshoot WiFi networks with the Ping tool?

placeholder

How to troubleshoot WiFi networks with the Ping tool?

Conducting ping tests routinely with a performing ping tool have multiple benefits. Pinging devices let WiFi networks managers know about the overall health of their networks. It’s essential to know the availability status of all the access points and routers —also, the latency rate of requests, Jitter, and packet losses.

Consequently, it is vital to know and understand the history of ping tests and how ping tests work. Tanaza is launching an improved ping tool, to help MSPs execute routine ping tests and stay up to date on the networks’ performance.

What is a ping tool?

A ping tool is a software utility to test the reachability between the requesting host and a destination host. It is the most common network tool used to provide a basic connectivity test.

The ping measures the time that takes for packets to arrive at the destination host from the requesting host and back. This tool is useful for troubleshooting WiFi networks and test responses. Also, it provides users with the exact location where a specific problem may exist in the network.

For example, if the connection to the Internet goes down in a specific location, the ping utility can be useful. It helps to better understand where the problem exists if it is within a particular AP or the WiFi network.

How does the ping tool work?

Users can select a specific access point and use it to PING another device. To ping the device, users can use an IP address or a domain name.

Once the user inputs the information and clicks PING, the system starts immediately pinging the intended device. After the attempts are over, the tool displays reached information values for average latency, loss rate, and jitter. Also, it shows a full history of the console. Users can also restart the ping if needed.

Also, users can set advanced settings like interleave, packet size, attempt counts, and timeout, in the advanced mode tab. Moreover, users can carry out multiple pings in parallel, with a maximum of 10 ping instances happening at once.

How do users visualize the ping results in the Tanaza platform?

The Tanaza platform displays the ping results through dynamic diagrams. These graphics allow users to get a quick overview of the network situation in a fast and organized way.

Also, if users switch to the console view, they visualize the history of the attempts updated in real-time. The ping tool measures and records the packet round trip time, which gives an idea of latency between the two devices. Also, it measures if there are any losses along the way while performing the ping test.

In the new Tanaza platform, ping tests can be carried out between local and remote devices, such as over the Internet or a VPN. As long as the devices are online and updated with the latest TanazaOS firmware (current version 3.3.2), tests can be carried out without any inconvenience. Ping tests cannot be carried out on disabled access points.

How to read data from the ping tool

1. What is Latency Rate?

In terms of networking, latency is the time that takes for a data packet to travel from the requesting source to the access point and then for the latter, to process it and send back an answer. For performance purposes, MSPs should always look for the timing to remain as close to zero as possible. In short, low latency implies there are no delays, and instead, high latency means there are many delays.

What would be an acceptable Latency in WiFi networks?

The average latency of a WiFi network will depend on two factors: wired or wireless connection, and quality signal. The information below is valid when pinging devices on the local network.

Typically, a wired connection has a latency of 1 millisecond or less. Whereas a wireless connection should generally be in the range of 1 to 3 milliseconds. The reason a wireless connection experiences more latency is due to the operation of encryption and decryption that it needs to go through, which in general lines takes more time compared to a wired connection. The wired connection only needs hardware operation and transmission, and as a result, the latency is much less.

Last but not least, the network signal is another key point to factor in. The higher the network signal is, the lower the ping would be. So, network managers know that the speed related to their networks depends mainly on signal quality.

When the average latency figures in networks (wired or wireless) go above the aforementioned threshold, that’s when network managers should start to worry. If latency figures, go as high as 4-6 milliseconds, it means the network is heavily congested. Also, it could mean that networks might be experiencing lots of collisions. Any figures beyond 4-6 milliseconds, it means poor WiFi connection or also interference caused by other devices nearby.

2. What is Jitter?

In networking, jitter -measured in milliseconds, is the variation in latency and response time of packets carrying data, like voice or video, over a communication channel. A healthy connection would consistently report back the same latency at all times. In contrast, slow or congested networks will show high levels of jitter.

In a network, the sender forwards packets spaced evenly apart in a continuous stream. However, if the WiFi network is congested packets start queuing. Also, if there are errors in the network configuration, it can result in significant variations in packet delay. This means that packets will not be received in the same order or possibly drop entirely on the way.

When MSPs are in the presence of high-level jitter variations, it can only indicate problems within the network. For example, web browsing is highly resistant to jitter, however, streaming data, voice, or music is much more susceptible.

What would be an acceptable Jitter in WiFi networks?

If a user has a VoIP call and the jitter surpasses 40ms, it will cause severe deterioration in the VoIP call quality. The tolerance of jitter will depend on the application. But, as a rule of thumb, jitter tolerance should be below 30ms to guarantee excellent user experience.

3. What is Packet Loss?

When it comes to monitoring network performance, it is crucial to know and understand how to stop packet loss. Let’s get started by unfolding first the terminology.

A packet is a small unit of data carried over a digital network. Data packets follow a defined path to keep the efficiency in networks. However, before a data packet is sent to the receiver, it is evenly distributed into blocks of information. Once the data packets arrive at the destination, they reassemble again.

Why does packet loss happen?

When packets travel within the network, sometimes they can’t make it through and won’t arrive at their destination. Data packets get lost or dropped in transit during their journey.

Thus, when packets are not successfully delivered, it slows down the speed of network traffic, as it causes a blockage. This creates a sort of congestion in the network throughput and takes upon bandwidth.

The risk of not acting soon to reduce the percentage of lost rate can be costly for MSPs. Investing in additional IT structure and adding more bandwidth to fix the latency caused by packet loss, would be needed.

What are the causes of packet loss?

The exact cause for data packet loss can be due to a variety of reasons. For example, the most common cause is network congestion. When the network traffic hits its maximum capacity, packets start queuing to be delivered. As a result, data packets get a hard hit when a network is catching up with traffic. However, most applications will resend the data packets or slow down the transfer speed to allow them to make it through.

Other reasons for packet loss could be overloaded devices or issues with the network hardware. Also, inadequate structure for handling packet loss, and even security threats in the network. However, there are ways to prevent packet loss, although it’s worth highlighting that it’s impossible to achieve zero packet loss. There will always be issues in the network, multiple client devices connected at the same time or overloaded devices. This would make it extremely difficult to achieve a zero % loss rate.

What can MSPs do to troubleshoot networks?

Troubleshooting networks with high levels of Latency and Jitter

The leading cause of high variations in Jitter and Latency on WiFi networks is a mix of bandwidth, potential interference, and the number of client devices connected to the network at the same time. To improve latency, MSPs need to work around these aspects. On the other side, variations in the amount of bandwidth used cause Jitter.

Hence, a slow connection speed would cause high latency. The more interference, the lower the bandwidth available to use. Finally, the more client devices connected to the network, the higher the variation in Jitter. Also, connected devices that aren’t transmitting data cause more interference, thus increasing levels of Jitter.

Apply these hacks to reduce latency and jitter levels

1. Hardware, hardware, hardware! Make sure your equipment is up to date with the current WiFi standards. Legacy access points don’t make proper use of the spectrum and can be more sensitive to noise, causing problems to signal, therefore affecting throughput.

2. One of the key recommendations is to reduce heavy users and get them to connect to the Ethernet, to take the load off from the WiFi network. However, in outdoor – medium and large scale deployments, this is not scalable, to not say nearly impossible. With the Tanaza platform, MSPs can limit the amount of bandwidth at the SSID and client level.

3. Assess the channel bonding of your wireless networks. For instance, newer devices allow users to have 40Mbps channels on the 2.4GHz and up to 160Mbps on the 5GHz. To lower the latency is essential to have more bandwidth.

4. Deploying more WiFi access points will help to increase the signal and provide more bandwidth, in consequence, reducing levels of latency and Jitter.

5. Set up multiple access points using different frequencies rather than using repeaters, which unfortunately help wasting bandwidth.

Troubleshooting WiFi networks with high packet loss rate

Our first recommendation before trying anything else. First, make sure all the access points and routers within the network are updated with the latest Tanaza firmware. Our R&D team always fixes bugs and issues with each firmware release.

Try these simple tricks to fix packet loss:

  1. Check all connections are properly configured and plugged-in correctly.
  2. Restart the whole system. It might give a clean jumpstart to the network pushing it to fix internal glitches or bugs.
  3. Remove any application or devices capable of causing static, like Bluetooth, wireless devices, and cameras.
  4. Use an Ethernet cable connection instead of WiFi. Packets tend to get lost easily over WiFi. Consider even a fiber optic cable to connect to the Internet.
  5. Consider, also replacing legacy hardware and look out for the network infrastructure, too.
  6. Deploy more access points. This will increase the signal and provide more bandwidth, thus reducing jitter and latency.

A final thought on this section: it is critical for optimal network performance to detect, troubleshoot, and prevent packet losses. However, it’s fundamental to keep in mind that packet loss happens, and no software in the market can stop this. Monitoring constantly the network and having visibility of it, is a way to prevent and lessen the impact on packet loss.
