Frequency Range 6GHz – More capacity, less latency in the future of WiFi
The first improvement of WiFi 6 technology is basically more capacity. Specifically, access points will be able to operate on the 6GHz spectrum, in addition to the 2.4GHz and 5GHz that currently exist. The possibility to use this new frequency range guarantees lower latency for applications in higher density environments. Moreover, 6GHz includes the orthogonal frequency-division multiple access (OFDMA) feature from cellular technologies, which takes advantage of servicing multiple users on sub-channels transmitted simultaneously.
There are also changes in regulations related to the 6GHz frequency range. WiFi access points have to be registered in databases and become ‘geolocation aware’. They must support the following standards:
- Low Power Indoor (LPI)
- Power Spectral Density (PSD)
- Automated Frequency Coordination (AFC)
LPI and PSD are rules for restricting the power output of indoor 6 GHz devices, to limit interference with each other or with licensed outdoor use. AFC is for outdoor 6 GHz devices and consults with a database based on the FCC’s Universal Licensing System so that 6 GHz access points can avoid interfering with licensed applications.
Wi-Fi 6 has multiple Wi-Fi channels and these channels can be allocated more effectively to permit multiple transmissions to multiple users at the same time. Hence, when organisations power outdoor Wi-Fi 6 for users, it means more efficiency, less overheads and also support for a greater variety of applications.
20MHz vs 40MHz vs 80MHz vs 160MHz – What is the best Channel Bandwidth for Business?
20MHz – 40MHz – 80MHz channels are recommended for business, while 160MHz is best suited for environments with low channel utilization.
For a correct deployment, it is important to distinguish the correct channel bandwidth selection. The channel bandwidth can really affect the performance on networks.
20MHz is the most common Wi-Fi bandwidth as most users still opt to use 2.4GHz radios (almost never in 5GHz).
20MHz is the correct channel bandwidth for businesses that want to guarantee high levels of connection for remote workers or users with high expectations.
Today, WiFi customers prefer to use video streaming and video calls: this requires high levels of packets in download for buffering in streaming services (Netflix, Amazon Video, Youtube, for instance) and video-communications applications (Google Meet, Skype, and Slack Call, for instance). In 5GHz bandwidth, thanks to a large amount of non-overlapping channels, providers will not face any problem doing anything, and the internet speed will not have any significant interruptions.
40MHz is the best channel bandwidth for businesses requiring a medium-high level of data transfer rate and higher than 20MHz.
IT professionals can still get 12 non-overlapping channels if combined with a 5MHz frequency.
This channel bandwidth is used by both 2.4GHz and 5GHz. It has a higher speed but it’s not particularly suggested in crowded areas, especially with 2.4Ghz. MSPs, ISPs, and SPs should use it, only on 5GHz and for a restricted number of connected devices. It’s easy to understand how these few users will receive a perfect signal.
80MHz is the last suggested channel bandwidth for business use. This channel bandwidth has the highest data transfer rate for the commercial ranges. The absence of non-overlapping channels to operate within makes high levels of congestion with high levels of traffic. 80GHz is the best channel for IT professionals that think “quality over quantity”: this bandwidth guarantees the highest signal performances for a really limited number of users.
160MHz deserves a separate chapter. It is totally not recommended for IT professionals. And often neither for home use. 160MHz channel bandwidth is perfect for activities like Ultra-HD streaming and professional gaming. Activities that can create a high rate of congestion, especially with the next networks. It’s easy to understand how a single user with this channel bandwidth creates congestion for all the others. Totally unrecommended for business solutions.
Subcarrier spacing drastically reduced to improve WIFi efficiency
WPA3 WIFI6 – Future of WiFi means higher levels of security
This next-generation security protocol enables more robust authentication, delivers increased cryptographic strength for highly sensitive data markets, and maintains resiliency of mission critical networks.
All WPA3 networks:
– Use the latest security methods;
– Disallow outdated legacy protocols;
– Require use of Protected Management Frames (PMF);
What is Wi-Fi 7 and what are the next key features for MSPs, ISPs and SPs?
Wi-Fi 7 (802.11be) is the next standard of Wi-Fi technology that operates in the 6 GHz frequency band, in addition to the 2.4 GHz and 5 GHz bands used by previous versions of Wi-Fi. Wi-Fi 7 was designed to provide faster speeds, lower latency, and improved performance in crowded or congested environments, such as dense urban areas or large events.
Some key features of Wi-Fi 7 include:
Higher speeds: Wi-Fi 7 can achieve speeds of up to 9.6 Gbps, which is significantly faster than the maximum speeds of Wi-Fi 6 (6.9 Gbps) and Wi-Fi 5 (3.5 Gbps).
Lower latency: Wi-Fi 7 has lower latency than previous versions of Wi-Fi, which means that it can transmit data more quickly and with less delay. This can be particularly beneficial for applications that require real-time communication, such as online gaming or video conferencing.
Improved performance in crowded environments: Wi-Fi 7 uses advanced techniques such as beamforming and multi-user MIMO (MU-MIMO) to improve performance in crowded or congested environments. This can help reduce interference and improve the overall user experience.
Enhanced security: Wi-Fi 7 includes improved security features such as enhanced WPA3 encryption and support for the Wi-Fi Certified Secure program, which ensures that devices are secure by default.
A first Wi-Fi 7 demo commercial device is now available.
The future of WiFi is for the environment protection
Tanaza also took up on the challenge.
WiFi cloud management to reduce CO2 caused by unnecessary onsite travel
An activity that is now obsolete and in the long term causes increased pollution levels. Thanks to Tanaza, the cloud-based network management platform, IT teams can remotely configure and manage all network parameters from anywhere in the world without any unnecessary and environmentally harmful travel.
Network device upgrade to avoid planned obsolescence and reduce electronic waste
Several industry studies have shown that the average lifetime of WiFi devices is 3 to 4 years. Imagine for a second, the gas emissions and the amount of e-waste produced by manufacturing and replacing the current network infrastructure around the world.
Obviously, incumbent vendors have strong economic motivations to design devices that at some point break down or are not updated anymore and thus consequently are replaced. It’s called design with planned obsolescence. It happens in the world of home appliances, just as it happens in the networking industry. This is nothing new, but the situation has reached critical levels.
Here is a graph from the Global E-Waste Monitor 2020. We hope it will raise awareness of the problem of e-waste that planned obsolescence and the resulting waste generation creates:
Access points fall under the Small IT and telecommunication equipment classification
These two combined factors dramatically decrease the amount of e-waste produced, reducing network infrastructure costs for providers and contributing to environmental protection.
