Wi-Fi Alliance exec: ‘Think about what we will accomplish with what we’ve just been given with Wi-Fi 6E’
Wi-Fi Alliance’s Senior vice chairman of selling Kevin Robinson told RCR Wireless News that the Alliance is thrilled about the FCC’s decision to open 6 GHz for unlicensed Wi-Fi. consistent with him, the approval of Wi-Fi 6E is unprecedented, and it won’t be long before the production of Wi-Fi 6 devices which will operate within the new, wider band ramps up.
“When Wi-Fi got started,” he explained, “almost all Wi-Fi at the time was operating during a very small piece of the spectrum — about 60 megahertz of the spectrum — was all that was effectively used. But now, we’re going from that 60 megahertz to 1,600 megahertz with this new allocation in 6 GHz.”
The potential impact of such a rise in the spectrum becomes clearer once you consider everything that has already been accomplished on the tiny amount of spectrum available to Wi-Fi these past years.
“Think about what we will accomplish with what we’ve just been given,” added Robinson.
Robinson claims that that device with Wi-Fi 6E will become available very quickly, anticipating quite 300 million Wi-Fi 6E devices coming to plugin 2021.
“The expectation is for things like access points to return to plug within the fourth quarter of this year,” he continued. “In addition, W-Fi Alliance is going to be launching its certification for Wi-Fi 6 devices to work in 6 GHz in early 2021.”
His prediction echos further comments made by the Alliance on its website.
Robinson also stated that next year, flagship smartphones will already be implementing Wi-Fi 6E, which by making use of the broader channels in 6 GHz, a smartphone is going to be ready to achieve very high-performance numbers, which was previously impossible because phones send so few spatial streams.
“That’s incredible because previously, hitting those speeds required tons of antennas,” he said.
The “E” in Wi-Fi 6E stands for “extension” because Wi-fi 6E is just Wi-Fi 6, or the newest generation of wireless technology, extended into the 6 GHz band. during this way, the advantages of Wi-Fi 6E are literally just the advantages of the features offered by Wi-Fi 6 when utilized in a wider band.
When used with one connected device, maximum potential speeds of Wi-Fi 6 should be up to 40% higher compared to Wi-Fi 5 — a 6.1 Gbps increase. This feat of speed is accomplished through more efficient data encoding, leading to higher throughput. The chips wont to encode and decode the info packet into radio waves are getting more powerful and more capable of handling extra work.
The 9.6 Gbps speed of Wi-Fi 6 is more of a theoretical maximum; however, the sweetness of that 9.6 Gbps is that it doesn’t need to attend one device, but can instead be break up across an entire network of devices, leading to more speed for every device on the network.
This is because unlike Wi-Fi 5, Wi-Fi 6 utilizes a channel access method called Orthogonal Frequency Division Multiple Access, or OFDMA. the tactic allows for the division of a wireless channel into an outsized number of sub-channels, with all carrying data intended for a special device.
Wi-Fi 6 also has an improved version of multi-user or MU-MIMO that lets devices answer the wireless access point at an equivalent time that involves multiple antennas, which let them access point ask multiple devices directly. With Wi-Fi 5, the access point could ask devices at an equivalent time, but those devices couldn’t respond at an equivalent time.
“When you check out the performance improvements that came with Wi-Fi 6,” said Robinson, “to get the really high bandwidth promised, you needed these wide channels, and 6 GHz delivers those wide channels.”
“6 GHz helps deliver the complete potential of what Wi-Fi 6 was always designed to be,” he added.
Further, when it involves Wi-Fi use on the new band, only the devices supporting the newest Wi-Fi generation are going to be ready to operate within the new channel, ensuring high performance and efficiency.
“The backward operability that’s such a key a part of what made Wi-Fi great created some inefficiencies. Now, though, you’re only getting to have the foremost efficient Wi-Fi devices operating within the new band creating a really clean, pristine environment,” Robinson said.
