Wi-Fi 6 Launch 1 introduced a number of applied sciences (DL/UL OFDMA, DL HE MU-MIMO, 1024-QAM, HE TX Beamforming, and Goal Wake Time) which enabled better throughputs, decrease latency, and better reliability and spectral effectivity within the present 2.4/5 GHz networks.
With Wi-Fi 6E, Wi-Fi entered a brand new period – increasing using Wi-Fi 6 into the clear 6 GHz band – opening 1200 MHz of spectrum unbridled by legacy gadgets and constraints. This untapped spectrum affords as much as fourteen 80 MHz channels or seven 160 MHz channels in 6 GHz for bandwidth-intensive purposes.
This 1200 Mhz being greenfield spectrum meant that gadgets shouldn’t have to deal with legacy gadgets for airtime – thus realizing better spectral effectivity and community reliability, even in very dense and congested environments. Concurrently, the obligatory utilization of solely probably the most safe WPA3 Safety within the 6 GHz area has meant that not solely do gadgets working on this band expertise higher efficiency and reliability however that they’ve a safer, safer community they will depend on.
This extension of Wi-Fi 6 into the 6 GHz band has been probably the most consequential improve Wi-Fi has seen previously 15 years and it’s anticipated to generate financial development of as much as 4.6 trillion, per WFA alliance, within the subsequent 3 years.
With Wi-Fi 6 Launch 2 in early 2022, the Wi-Fi Alliance has unleashed a plethora of latest options and optimizations, geared toward assembly the ever-increasing calls for from immediately’s wi-fi environments.
Cisco has been working with the WFA alliance and different eco-system gamers to make sure the 6 GHz Wi-Fi expertise is optimized.
Cisco Catalyst 9136 is industries First (and solely present) Enterprise Class Entry Level to certify Wi-Fi6 launch 2:
Notable options of launch 2
- UL Multi-Person MIMO: Bettering add speeds by 90%, thus enabling hybrid work experiences (WebEx Video, Whiteboard), and different excessive bandwidth purposes to scale with none impression on expertise and efficiency.
- UL Prolonged Vary: a spread extension function, permitting for consumer gadgets to keep up connectivity farther from the entry level than ever earlier than – which means fewer over the net calls from cellular gadgets being dropped or connectivity misplaced.
- Multi-BSSID Management Body Optimizing numbers of management frames and liberating up airtime for information transmittal and receival. This interprets to an finish consumer’s improved community efficiency and high quality – particularly in a crowded, dense enterprise surroundings the place A number of BSSIDs are ever prevalent.
- Goal Wake Time Info Frames & Prolonged Sleep Time, extends its advantages to IoT gadgets, by permitting the STA to droop or/and resume an present TWT settlement, permitting extra versatile updates and optimizations of this settlement. Which means even when in low energy mode, a consumer system can shortly ramp up its efficiency as and when wanted – making certain seamless experiences whereas saving valuable battery life.
- UL Multi-user management/information disable: permits gadgets to proceed to take part in UL MU transmissions utilizing UL OFDMA acknowledgments and sounding suggestions through the introduction of a “information disable” solely mode, Leading to better DL throughputs and decrease community overheads because of DL Body acknowledgments.
The mixture of the 6 GHz clear spectrum and WiFi6 R2 newest printed commonplace baseline will allow the Wi-Fi ecosystem to allow METAVERSE use instances on Wi-Fi. We count on different ecosystem gamers to observe go well with and undertake 6E with launch 2.
