Whereas wi-fi applied sciences have continued to enhance in bandwidth, distance, and resilience in opposition to interference, most companies and basic customers haven’t but upgraded to Wi-Fi 6, final yr’s sequel to the older, standard 802.11ac (Wi-Fi 5) commonplace. That’s most likely for the very best, as chipmakers are actually shifting to Wi-Fi 6E, a superior, not too long ago accepted replace, and Qualcomm is prepared with new machine and router options that promise “VR-class low latency” and the quickest Wi-Fi speeds customers have seen.

At the moment, Qualcomm is saying the FastConnect 6900 and 6700, device-ready wi-fi methods that embody each Wi-Fi 6E and Bluetooth 5.2 for optimum wi-fi efficiency and energy effectivity. Whereas FastConnect 6700 affords a peak Wi-Fi pace of three gigabits per second (Gbps), the higher-end 6900 tops out at 3.6Gbps, utilizing four-stream dual-band simultaneous transmitting and 6GHz multi-band capabilities. These numbers are quicker than the 2- to 2.63Gbps peak Broadcom is claiming for its competing BCM4389, and Qualcomm is promising beneath 3-millisecond latency — sufficient to assist cable-free head-mounted displays for VR — with as much as eight instances higher latency discount in Wi-Fi-congested environments.

It’s laborious to overstate how essential Wi-Fi 6E is more likely to be for places of work, retail areas, and densely populated dwelling areas similar to residences. For the primary time in a long time, the brand new commonplace opens extra 6GHz radio spectrum to Wi-Fi, the equal of including a large, empty new freeway instantly subsequent to present 2.4GHz and 5GHz roads. Between further lanes and extra trendy infrastructure, customers will be capable of ship information quicker and with higher responsiveness, letting newer gadgets each keep away from and reduce congestion on the older roads. For those who’re working from dwelling, you’ll get excellent wi-fi efficiency no matter sign competitors out of your neighbors; places of work and shops will be capable of use next-generation VR headsets and holographic shows with out cables or community hiccups.

There’s an enormous year-over-year efficiency distinction in contrast with the prior FastConnect 6800, which was utilized in Samsung’s Galaxy Z Flip, LG’s V60, and Xiaomi’s Mi 10/Pro, amongst different gadgets. Along with almost or absolutely doubling the prior peak Wi-Fi pace of 1.8Gbps, FastConnect 6700 and 6900 assist Bluetooth 5.2 with LE Audio, the brand new high-efficiency audio commonplace that permits multi-point connectivity and open, broadcast-style streaming. Two Bluetooth-specific antennas are included to enhance each reliability and vary, whereas the LE Audio commonplace delivers a stronger mixture of low energy consumption and excessive sonic constancy than earlier than. Qualcomm notes that the brand new methods are constructed utilizing a 14-nanometer course of, delivering as much as 50% higher energy effectivity than prior-generation options.

On the router facet, Qualcomm can also be introducing 4 new Wi-Fi 6E Networking Professional platforms, every together with assist for Tri-Band Wi-Fi 6 — able to working concurrently on 2.4GHz, 5GHz, and 6GHZ frequency bands. Relying on the efficiency degree an OEM chooses, it could possibly supply something from a business- or campus-scale enterprise entry level to a house mesh Wi-Fi community, with assist for as much as 2,000 simultaneous purchasers.

All 4 of the Networking Professional platforms use quad-core ARM Cortex-A53 processors, however they differ in most throughput. With the highest-end 1610 platform, purchasers can collectively attain as much as 10.8Gbps of information utilization, twice the height of the lowest-end 610 platform. Nonetheless, the height single device-to-device switch pace is 2.4Gbps, which Qualcomm achieves utilizing an particularly dense (4,096 QAM) implementation of Wi-Fi 6E.

The 4 platforms are as follows:

  • Networking Professional 1610 (2.2GHz A53): As much as 16 streams, 10.8Gbps peak whole pace
  • Networking Professional 1210 (2.2GHz A53): As much as 12 streams, 8.4Gbps peak whole pace
  • Networking Professional 810 (1.8GHz A53): As much as Eight streams, 6.6Gbps peak whole pace
  • Networking Professional 610 (1.8GHz A53): As much as 6 streams, 5.4Gbps peak whole pace

Qualcomm is transport the Networking Professional platforms now, and expects them to be commercially obtainable in OEM merchandise this yr. The FastConnect 6900 and 6700 are sampling now to OEMs and are anticipated to seem in gadgets beginning within the second half of 2020.
