WiFi 7 and the controversy over 6 GHz unlicensed vs licensed spectrum


Even though the IEEE 802.11be standard is yet to be released officially, there are currently Wi-Fi 7 routers on the market from many major vendors. Wi-Fi 7 provides significantly faster speeds then WiFi 6 (IEEE 802.11ax), with ultra-low latencies and a better communication channel.  Thereby, more devices can be connected efficiently.

Wi-Fi 7 routers are capable of delivering wireless data transfer speeds of up to 46 Gbps, which is five times greater than that of Wi-Fi 6E routers. Wi-Fi 7 routers can also operate on multiple bands: carrier frequency operation is between 1 and 7.250 GHz while ensuring backward compatibility and coexistence with legacy IEEE Std 802.11 compliant devices operating in the 2.4 GHz, 5 GHz, and 6 GHz bands.  Latency is also lower with a Wi-Fi 7 router and channel connections are more efficient.

Some Wi-Fi 7 routers include the NETGEAR Nighthawk Tri-Band WiFi 7 Router BE19000 Wireless Speed, the TP-Link BE9300 Tri-Band Wi-Fi 7 Router ARCHER BE550, and the ASUS BE96U Tri-Band WiFi 7 Router RT-BE96U.

6 GHz Band Controversy:

As of September 2023, the following countries have adopted the policy of making the entire 6 GHz band available for unlicensed use: U.S., South Korea, Brazil, Saudi Arabia, Costa Rica, Peru. Canada has also made 1200 MHz of 6 GHz spectrum available for unlicensed services. The 6 GHz band is the largest allocation of unlicensed spectrum in the US and South Korea.

Some other countries that have enabled Wi-Fi in the 6 GHz band include: Andorra, Argentina, Australia, Austria, Bahrain, Belgium, CEPT.

China has chosen a licensed approach for the 6 GHz band, using the entire 1,200 MHz for 5G and future 6G services.

The Telecom Regulatory Authority of India (Trai) suggests that the lower end of the 6 GHz spectrum band can be allocated for unlicensed use, such as WiFi, while the upper end can be licensed for telecom use. Netgear said that the India DoT (Department of Telecommunications) is considering to delicense the lower band 6 GHz spectrum.

However, WRC 23 agreed to open up the 6 GHz band for future high-speed mobile communications (instead of for unlicensed WiFi).  The 6 GHz band (6.425-7.125 GHz) – was identified for mobile in every ITU Region – EMEA, the Americas and the Asia Pacific. Countries representing more than 60% of the world’s population asked to be included in the identification of this band for licensed mobile at WRC-23. The 6 GHz spectrum is now the harmonized home for the expansion of mobile capacity for 5G-Advanced and beyond.




WRC-23 concludes with decisions on low-band/mid-band spectrum and 6G (?)

Comcast Xfinity Communities Wi-Fi vs Charter’s Advanced Wi-Fi for Spectrum Business customers

Comcast has about 22 million Wi-Fi hotspots which are available  free of charge for its Comcast Business and Xfinity customers (including this author who has used their WiFi hotspots in Santa Clara, CA and Pacifica, CA).

Xfinity Communities serves about 250,000 properties from multi-dwelling units (MDUs) to single-family communities, assisted living residences, hospitals and college dormitories. Xfinity Communities has six special account managers to handle its top 40-50 largest property owners.  Some of the properties it serves are  spread out so the company is providing Wi-Fi not just to specific units but also in the lobbies, on the grounds and at the pool, etc.

Although Comcast has the technology to provide Wi-Fi to a whole building without wiring multiple individual units, it seems to prefer the more traditional model. “To serve individuals best you need some kind of wired technology,” said Mike Mancini, director of sales engineering for Xfinity Communities. “Every unit gets wired to make sure we can deliver the highest speeds possible,” he added.

Xfinity Communities can and does wire the dormitory building, but not every individual unit. “We do hook up entire buildings as well, and people don’t have gateways, they have an access point up on the wall. We can provide connectivity both ways, it really depends on the property. We’re very flexible,” Mancini said.

Xfinity Communities serves selected apartment buildings. With pre-installed xFi Gateways in every unit, residents get instant access to WiFi after moving in. They can sign up for Xfinity Internet upon arrival, lease the xFi Gateway, and get connected on the spot — all from the provider of the largest gig-speed network.


Separately, Charter Communications this week announced the availability of its Advanced Wi-Fi for Spectrum Business customers across its 41-state footprint.  Charter’s Advanced Wi-Fi includes its Red Dot Design router, which can support up to 200 devices simultaneously. And it includes greater coverage with Spectrum Wi-Fi Pods, which are additional access points for extended Wi-Fi coverage and more consistent speed to all corners of the business.

“Small businesses rely on technology, specifically the Internet and WiFi, to compete in today’s marketplace,” said Dave Rodrian, Group Vice President, WiFi Products, for Charter. “Now, with the launch of Advanced WiFi throughout our footprint, we can offer small and medium-sized businesses faster and more secure WiFi connections, giving them additional control over their network so they can improve their efficiency and productivity.”

Qualcomm FastConnect 7800 combining WiFi 7 and Bluetooth in single chip

Qualcomm Technologies has announced its first Wi-Fi 7 chip, the FastConnect 7800. Bundling the latest Wi-Fi (IEEE 802.11) and Bluetooth specifications, the new chip is sampling already and expected to be available for commercial products in the second half of 2022. Qualcomm said this should be the first Wi-Fi 7 chip to launch commercially, pending the start of certification of Wi-Fi 7 products.

Wi-Fi 7, also known as IEEE 802.11be, is still in development so has not yet been approved as an IEEE standard. It includes features like 4k QAM, 320MHz channel bandwidth, and multi-link capabilities. Though, as with every standard, implementation is where truly differentiated performance is achieved. For example, multi-link can be implemented with simultaneous links or alternating links. Further, one of those links may be implemented using the narrow and congested 2.4GHz band (which could otherwise be reserved for Bluetooth or IoT devices). Design choices such as these will dictate how well your next devices will be able to harness Wi-Fi 7 speed and latency benefits, so Qualcomm Technologies’ approach is to offer a flexible solution that will include all the options.

Qualcomm said it expects the WiFi 7 system to deliver peak speeds up to 5.8Gbps, via single 320MHz or paired 160MHz channels, falling to 4.3Gbps when the 6GHz band is not be available. Latency should be less than 2ms.

One of the key features of the new system is High Band Simultaneous (HBS) Multi-Link technology. This simultaneously leverages two Wi-Fi radios for four streams of high band connectivity in the 5GHz and/or 6GHz bands. These connections can deliver the highest throughput and lowest sustained latency, while reserving high-traffic 2.4GHz spectrum for Bluetooth and lower-bandwidth Wi-Fi applications.

In addition, the new chip extends 4-Stream Dual-Band Simultaneous (DBS) into the high bands. This builds on Qualcomm’s 4-Stream DBS (2×2 + 2×2) with 5 and/or 6GHz Wi-Fi links used in concert for extreme low latency performance between access point and client or independently for multi-client scenarios. For instance, a mobile device connecting to a Wi-Fi 6/6E access point (for 2×2 backhaul in high band spectrum) can concurrently connect to an XR headset (for 2×2 fronthaul also in high band spectrum), free from the low bandwidth and congestion of the 2.4GHz band.

Qualcomm also promises high-quality Bluetooth audio with the new chip, which includes support for Snapdragon Sound. Its Intelligent Dual Bluetooth offers two radios with enhanced connections, enabling Bluetooth accessories to work up to twice the range, to pair in half the time, and speed up changing a Bluetooth connection between devices, according to the company.

Special attention was given to ensure that FastConnect 7800 maintains compatibility with all prior generation devices. Whatever generation of Wi-Fi or Bluetooth being used, FastConnect 7800 is built to provide the best connectivity. Sampling is already underway, with commercial availability rolling out in the second half of 2022.

At the launch at MWC, several companies including Honor, Meta, Xiaomi, Vivo and Oppo said they plan to use the new chip in future products.
