Qualcomm has just announced the FastConnect 7800 WiFi 7 and Bluetooth 5.3 subsystem for smartphones, laptops, and virtual reality headsets promising peak speeds of 5.8 Gbps as well as sub-2 millisecond latency. We first detailed some of WiFi 7 features such as up to 40 Gbps link, and real-time capabilities when MediaTek showcased its future 802.11be compliant Filogic processor to customers, so it should be no surprise that Qualcomm had been working on its own solution, and announced it at Mobile World Congress 2022. Qualcomm FastConnect 7800 (WCN785x-1, WCN785x-5) specifications: Wi-Fi Standards – Wi-Fi 7 (802.11be), Wi-Fi 6E, Wi-Fi 6 (802.11ax), 802.11ac Wave 2, 802.11a/b/g, 802.11n Spectral Bands: 2.4GHz, 5GHz, 6GHz Peak QAM: 4K QAM Peak speed: 5.8Gbps or 4.3Gbps where the 6GHz spectrum is not available Features 4-stream Dual-band simultaneous (DBS) extended into the High Bands Multi-Link Operation (MLO) using 320 MHz (Single channel or 160 + 160) 8×8 […]
WiFi 7 (802.11be) will support up to 40 Gbps links, real-time applications
I still don’t own a WiFi 6 router, but MediaTek has already started to demonstrate WiFi 7 (802.11be) to customers with solutions based on upcoming Filogic 802.11be processors which deliver “super-fast speeds and low latency transmission” and provide a “true wireline/Ethernet replacement for super high-bandwidth applications”. The company goes on to explain that Wi-Fi 7 relies on the same 2.4GHz, 5GHz, and 6GHz frequencies as WiFi 6/6E, but can still provide 2.4x higher speeds than Wi-Fi 6, even with the same number of antennas, since WiFi 7 can utilize 320Mhz channels and support 4K QAM (quadrature amplitude modulation) technology. There’s limited information about MediaTek Filogic 802.11be WiFi 7 processors since it will take a few more years before becoming available, but we can find more details in a document entitled “Current Status and Directions of IEEE 802.11be, the Future Wi-Fi 7” from IEEE Xplore. Here are some of the […]
