Qualcomm debuts WiFi 6E chipsets for mesh networks debuting in 2021

on

Qualcomm mentioned Tuesday that it’s going to launch a collection of 4 mesh WiFi 6 and WiFi 6E chipsets in time for brand new merchandise to ship in early 2021. Whereas Qualcomm confirmed a prototype of the brand new mesh nodes which might be smaller than a smartphone, executives mentioned that they count on customers will want extra mesh nodes than they did for prior generations.

Qualcomm introduced 4 new chipsets, a part of what it’s calling its Immersive House platform: the Immersive House 214 and 216, in addition to the Immersive House 316 and 318. The chipsets have been endorsed by 9 router makers together with Belkin, Netgear, TP-Hyperlink and Xiaomi, nearly definitely implying that their units will help the brand new chipsets.

Right here’s a fast abstract of the brand new chipsets, all of which can help 160MHz channels within the 5GHz band:

  • Immersive House 214: Four-stream WiFi 6 in a 2×2 (2.4GHz) and 2×2 (5GHz) configuration, three.0Gbps complete bandwidth
  • Immersive House 216: 6-stream WiFi 6 in a 2×2 (2.4GHz) and 4×4 (5GHz) configuration, 5.4Gbps complete bandwidth
  • Immersive House 316: 6-stream WiFi in a 2×2 (2.4GHz) and 2×2 (5GHz) and 2×2 (6GHz) configuration, 5.4Gbps complete bandwidth
  • Immersive House 318: Eight-stream WiFi in a 2×2 (2.4GHz) and 2×2 (5GHz) and 4×4 (6GHz) configuration, 7.8Gbps complete bandwidth

The latter two are probably the most important. Along with the usual 2.4GHz and 5GHz frequencies, the tri-band 316 and 318 present a devoted 6GHz backchannel for the routers to speak to your private home’s gateway with out interference. That’s a operate of Wi-Fi 6E, which makes use of the 6GHz frequency spectrum that was freed up final 12 months and has been included in chips from Broadcom and others earlier in 2020.

Qualcomm is claiming substnatial efficiency elevated over older WiFi 5 applied sciences in addition to (natually) over the competitors.

The 6GHz backhaul issues as a result of it creates a devoted categorical lane for a tool to speak straight again to the gateway, A mesh community communicates information wirelessly between your private home gateway or router and varied units all through the house. Legacy Wi-Fi units use the two.4GHz band; extra trendy ones use the 5GHz frequency. Older chipsets—even Qualcomm’s 216 and 218 chipsets, launched in the present day — use the 5GHz frequency band to speak with high-bandwidth units like smartphones, sport consoles and streaming units, then use the similar channel to ship that information forwards and backwards to the house gateway. All of the back-and-forth creates interference and lowers throughput. The 6GHz backchannel theoretically improves general throughput.

Including WiFi 6E means extra bandwidth, extra nodes

Now that Qualcomm has added WiFi 6E to its portfolio, the corporate is promoting the advantages of the brand new know-how—and explaining why a mere 5GHz mesh isn’t as environment friendly. 

“To raised perceive this, we take a single high-bandwidth utility,” Nick Kucharewski, vice chairman and normal supervisor of wi-fi infrastructure and networking, mentioned in a prerecorded video. “As it’s positioned additional and additional away from the [5GHz] mesh, the pace through which it’s transferring information turns into slower, which implies it’s occupying the radio waves and airspace for an extended time period. Which means that there’s much less out there time on the community for the entire different units on the community. Consequently, this high-bandwidth system positioned additional away from the mesh not solely experiences decrease efficiency itself, however it may well have an effect of bringing down the efficiency of different units on the community.”

One of many methods through which Qualcomm plans to get round that is what it calls “densification”—in impact, inserting extra routers inside your private home. Whereas Qualcomm’s Kucharewski argued that it places extra high-bandwidth routers nearer to high-bandwidth units, it additionally permits the interference-sensitive 6GHz backhaul to function extra easily. The smaller mesh nodes, nevertheless, could be positioned unobtrusively round your private home, he mentioned, together with straight into AC retailers.
