How disaggregation allows you to reduce your CAPEX and OPEX

The disaggregation concept embraces the open-source approach where WiFi solution providers can decouple their hardware choice from their software choice. This decoupling trend has already been successful in other industries such as the computer and smartphone markets.

In the WiFi industry, disaggregation enables WiFi professionals to control their costs when deploying or upgrading a WiFi network and obtaining significant cost savings.

How disaggregation allows you to reduce your CAPEX and OPEX

At Tanaza, we fully embrace the disaggregation concept and our software allows you to choose the hardware vendor most suitable for their deployment. Our latest product, TanazaOS is a Linux-based operating system for centralized wireless network management developed based on the disaggregation concept. TanazaOS allows enterprises and service providers to reduce their CAPEX OPEX.

Thanks to disaggregation, the business model of a WiFi solution provider using TanazaOS encourages them to:

 

Reduce WiFi hardware cost

For example, when a WiFi solution provider using TanazaOS has to decide the type of hardware for his next WiFi deployment, he will be able to choose cheaper wireless devices such as consumer/SMB devices which cost around $100/unit, unlike someone using a vendor-lock-in solution who will have to spend around $300/unit (hardware + software solution).

By using TanazaOS, a WiFi administrator enjoy the same set of professional features whatever the model of access point selected. Features include for example remote monitoring, centralized configuration, multi-site management, and self-provisioning.

How disaggregation allows you to reduce your CAPEX and OPEX

Save time and money for the WiFi deployment

TanazaOS self-provisioning system enables WiFi administrators to pre-configure the access points before shipping them to their customers (offline configuration).
Once online, the wireless devices will automatically sync the configuration, allowing WiFi administrators to speed up the WiFi network deployment and to reduce on-site travel costs. Moreover, large WiFi network configurations are facilitated thanks to the network-wide configuration system.

 

Save money on WiFi infrastructure maintenance – Reduce Capex Opex

When managing a WiFi network, the TanazaOS’ remote management feature enables WiFi administrators to reduce maintenance and troubleshooting cost: receive email alerts in case of access point disconnections, perform manual or scheduled reboots directly from the cloud, and keep an eye on your access points status thanks to the global map. This has direct impacts on maintenance budget such as no need for technicians on site, the fast configuration from a centralized platform, firmware’ scheduled upgrade, and disconnection alerts.

 

TanazaOS is conceived around the disaggregation concept, which means offering the option to select software from one vendor and run it on hardware from a different manufacturer. It is an operating system that supports WiFi solution providers who are looking for a flexible and efficient self-provisioning system that facilitates unlimited scalability and helps in delivering wireless networking services faster.

At Tanaza, we want to deliver a complete and cutting-edge product. With this in mind, we are constantly expanding our set of features. For more information about the new TanazaOS, feel free to try the interactive demo or to contact one of our Tanaza consultants.

How many access points do you need for your WiFi hotspot

How many access points do you need for your WiFi hotspot

When deploying a Wi-Fi infrastructure in public locations, one of the key element to ensure a good user experience is the number and the type of access points to use.

Indeed, if the number of access points is too low compared to the number of Wi-Fi users, then problems of internet speed might occur because of the overuse of the wireless devices and the bandwidth overload. Usually, the maximum number of concurrent users is written on the manufacturer spreadsheet, but in practice it can vary according to the use of your network and the internet services you want to offer to your Wi-Fi users.

By using the Tanaza Access Point Selector, you can select the type of location and its size to estimate the maximum number of concurrent users. The number of concurrent users is the number of Wi-Fi users currently connected to the Wi-Fi network. It is calculated according to the type of location, its size, and the average time that a user spends on the internet. Count for example ten concurrent users for a large Café, or 140 for a large hotel.

Then, you should calculate the bandwidth needed by the user according to the usage of the network. For example, if you want your users to be able to chat, check their emails and use social media, consider a minimum of 560 kbit/s per user. If you want them to be also able to do VoIP calls, video calls, and video streaming, 3.28 Mbit/s is the estimated bandwidth per user. Your internet provider will be in charge to furnish you with the bandwidth required.

Last but not least, select the characteristics of the access point such as the installation type, the radiation shape, the vendor and the main technology aspects (indoor, outdoor, AC, dual radio…). The Tanaza Access Point Selector will give you an estimation of the required units number, and the different models that fit the best your project.

/!\ Remember that the Tanaza Access Point Selector estimates the required bandwidth based on documentation and our experience on-site with our customers.

WPA3: what are the main changes to the wireless security standard

WPA3: what are the main changes to the wireless security standard

wpa3
On Monday, 8th of January, Wi-Fi Alliance, the non-profit organisation that promotes Wi-Fi technology and certifies Wi-Fi products, introduced “enhancement and new features for Wi-Fi Protected Access” .

After the KRACK attack and the discovery of WPA2 security problem that was putting at hijack risk all WPA2-compatible device like routers, computers and smartphones, Wi-Fi Alliance has announced a new security protocol: WPA3. WPA3 is a substitute for WPA2 (the wireless security standard since 2004) and should be landed later in 2018.

Four new capabilities will be launched in 2018 as part of the Wi-Fi certified WPA3. These features, available for personal and Wi-Fi networks enterprises, consist in delivering more robust protection regarding user’s password to access a Wi-Fi network and simplifying the security configuration for devices with a limited, or no display interface.

For example, a WPA3 key improvement aims to block “dictionary attacks”, or when a hacker tries to gain unauthorised access to a computer system by using a large set of words to generate potential passwords.
The new security protocol should prevent hackers from guessing a list of potential passwords to access a Wi-Fi network. Moreover, the hacker will be blocked after too many failed password thanks to its new handshake system ( WPA2 currently uses a four-way handshake).

Another interesting change touches on the open Wi-Fi networks. Open Wi-Fi networks are all networks in public spaces like café, airport, parks… that are not encrypted and so risky for the user whose data could be intercepted by a hacker.
WPA3 will use individualized data encryption that muddles the connection between each device on a network and the router. By doing so, WPA3 prevents hackers from stealing data or modifying websites. 


Obviously, building a new wireless security standard takes time, and WPA3 won’t substitute WPA2 before few months, but Wi-Fi Alliance underlined the necessity of updating Wi-Fi security in a modern society where the Wi-Fi demand is increasing.

How to choose the best access point for your restaurant’s WiFi network (part 1)

How to choose the best access point for your restaurant’s WiFi network (part 1)

restaurant's WiFi network

Are you planning to deploy a new Wi-Fi network in restaurants? Read this article to find out the three main requirements for a successful Wi-Fi deployment.

When setting up a new Wi-Fi network, you need to make sure you choose the right access point depending on the environment in which it will be deployed and your project’s budget. As for Wi-Fi projects targeting restaurants, you need to consider the following aspects: the size of the network’s covered area, the number of concurrent users and internet usage.

 

1. Location size

 

The first step to consider is the size of your Wi-Fi network’s location: is the size of your restaurant big, medium or small?

On average, a large restaurant can hold from 80-200 people, a medium-sized restaurant from 30-80 people and a small restaurant from 10-30 people. Depending on the size of your venue, you will need to choose one or more access points to cover the area. Also, should your restaurant include a terrace or a small garden, consider that you will need to install not only indoor but also outdoor devices for your deployment. Check out the list of Tanaza’s supported access points: by being multi-vendor, Tanaza offers a wide range of devices, both for indoor and outdoor environments.

 

2. Number of concurrent users

 

Based on your location size, the number of concurrent users connected to your network will vary accordingly. The network of a large restaurant may host approximately a maximum of 30 concurrent Wi-Fi users, the network of a medium-size restaurant may host a maximum of 12 concurrent users, whereas the network of a small deployment will likely handle an average maximum number of 5 concurrent users.

 

3. Internet usage

 

Lastly, it is important to pinpoint what kind of online activity your Wi-Fi users will do while being connected to your Wi-Fi network. Indeed, some applications consume more bandwidth than others: for instance, the rate of data transfer in your network – measured in bits per second (bit/s) – will be lower when users message and chat on Facebook, Whatsapp or Telegram, check their emails and browse the web. On the other hand, a higher number of bits per second will be transmitted across your network when users share or download/upload pictures and files on Dropbox and Google Drive, stream Youtube and Netflix videos, make VoIP calls or video calls on Skype.

Security breach in WPA2 protocol: what is the KRACK attack?

Security breach in WPA2 protocol: what is the KRACK attack?

Security breach in WPA2 protocol: what is the KRACK attack
For the past few days, you have been able to read on the internet that Wi-Fi WPA2 protocol has been having? issues regarding its data security. In this article, we will explain this data security issue entails and why Tanaza is not concerned by this flaw.

“KRACK Wi-Fi attack threatens all networks”, “KRACK Wi-Fi flaw, the big issue for Wi-Fi network”… the internet has been  in shambles for ten days due to the flaw discovery on the Wi-Fi network security process.

 

What is the KRACK issue?

KRACK stands for Key Reinstallation AttaCK and it designates the issue occurring when the third step of a four-way authentication process, performs in the wrong way.
To be clear, during the third step of the authentication process (when a device tries to connect to a protected Wi-Fi network), the encryption key can be sent multiple times to get access to the protected Wi-Fi network. Security issues occur when a hacker can collect this information and replay the transmission to break the Wi-Fi security encryption key.

 

What happens when the Wi-Fi encryption key is broken?

If a hacker gets the encryption key, they will be able to “sniff” your data and steal your sensitive information such as credit card details, emails, pictures, passwords and so on. The risk is the same as using a non-protected Wi-Fi network; users data is potentially accessible to all.
Moreover, the United-States Computer Emergency Readiness Team declared about KRACK issues that “the impact of exploiting these vulnerabilities includes decryption, packet replay, TCP connection hijacking, HTTP content injection, and others”.

 

Which devices are vulnerable?

The KRACK attack is not an issue for the device itself,  but the information it contains. All data sent on a Wi-Fi network without encryption key is as vulnerable as it when the user visits websites that are not HTTPS. You need to update your smartphone, tablet, router and computer with the latest security release to reduce the risk of data theft. Nevertheless, researchers said Android devices were more likely to be at risk rather than other mobile phones, same for Linux runners, considered as the most vulnerable devices.

 

Why are Tanaza users not concerned by this KRACK issue?

To prevent KRACK attacks in any Tanaza network, Tanaza introduced the fix in its latest firmware release. To avoid any risk, both the firmware and the customer device have to contain the fix for this attack.

This specific attack is against the 4-way handshake and it’s explicitly intended to exploit customers devices rather than access points. By using the Man-in-the-Middle attack (or MitM), hackers try to gather sensible data by misleading the device for the connection authentication and the user for the web surfing security (e.g. preventing websites from using HTTPS encryption and collecting any data such as usernames and passwords during any login process).
In a few words, if your access points runs on the latest Tanaza firmware and your devices are updated, you are protected from this KRACK issue.

4 reasons why 5G cellular won’t be a threat to Wi-Fi

4 reasons why 5G cellular won’t be a threat to Wi-Fi

resto2
5G is the next big revolution in mobile connectivity, is expected to be able to handle the increasing traffic related to the higher need for mobile data. The 5G wireless technology aims at providing better mobile broadband connectivity and speed for a wider range of customers.

 

In this scenario, is there a chance that the new 5G cellular network will eventually replace Wi-Fi?

 

We answered this question providing the main 4 reasons as to why the 5th generation wireless system (5G) and next generation Wi-Fi will probably coexist without representing a threat one for the other. In doing so, we relied on information collected by different sources, including: The 5G vs WiFi False Debate by Adlane Fellah, Shared Spectrum: Enabling 5G Mobile Broadband by Alex Marcham and 5G CELLULAR: WHY WI-FI NOT JUST SURVIVES, BUT PROSPERS by Craig Mathias.

 

1. Mobile users will likely continue to favour Wi-Fi over mobile connectivity 

 

Currently, many mobile users prefer using Wi-Fi networks instead of 4G cellular ones. In particular, in developing countries where mobile connectivity is lacking and in developed mobile markets where mobile data is overpriced and limited, Wi-Fi is a valuable choice among smartphone users. Accordingly, as 5G is going to be the evolution of the current 4G cellular network, it is likely that many users will still favor Wi-Fi over 5G.

 

2. Wi-Fi will still be an affordable alternative to 5G

 

According to Cisco, by the end of 2021 data traffic on mobile networks per month will reach 49 EB (exabytes), in line with the development registered between 2011 and 2015. Consequently, the new 5G cellular, other than on the licensed spectrum, will also operate on the more affordable unlicensed and shared spectrum. This spectrum, in fact, currently enables technologies like Wi-Fi to foster connectivity and facilitate innovation while also carrying the growing number of data traffic expected in upcoming years.

To handle the large of amount of data traffic coming their way, network operators will opt to work with all technologies operating on the unlicensed spectrum, as opposed to solely relying on private licensed ones. This scenario might make it possible for customers in the Wi-Fi market – other than mobile network operators – to opt for 5G over Wi-Fi in the unlicensed and shared spectrum. Nevertheless, despite 5G’s well-performing connection, it is likely that it will be offered at a high price. This will continue to make Wi-Fi a valuable and affordable alternative choice for many customers due to the fact that lot of effort and money is required to enable the 5G connection to work with both the licensed and the unlicensed spectrum based on different protocols.

 

3. Wi-Fi already masters dense deployments

 

Given the expected extensive data traffic in the upcoming years, 5G will also rely more and more on small cells, which are known to be very effective to improve capacity, coverage and data range in congested areas. From this point of view, as opposed to 5G, Wi-Fi already has a big advantage, as it masters crowded deployments. Compared to the other wireless access technologies, Wi-Fi has the right requirements to handle the growing demand for connectivity by being able to increase the capacity of mobile networks and carrying large amounts of data traffic.

 

4. The Wi-Fi market is expected to increase 

 

In the past few years, WI-Fi along with other cellular networks have developed extensively and its growth predictions are far optimistic. In fact, the global hotspot predictions for 2015-2020 made by Cisco’s VNI Mobile, show that Wi-Fi traffic, both from mobile and Wi-Fi-only devices, will account for 53% of total IP traffic by 2019.
