The FCC has made a swath of 1200 MHz available for Wi-Fi. Unlike an invasive species, Wi-Fi must respect the rights of services that already use the frequency band. Here’s why and how.
Wi-Fi 6E is coming, chipsets with MIMO now sampling
The QCS-AX2 series from ON Semiconductor brings 6 GHz Wi-Fi 6E to routers and access points. Just as LTE cellular is running out of capacity (hence 5G), so is Wi-Fi. Originally operating at 2.4 GHz (70 MHz band), IEEE 802.3n added 5 GHz, which supplemented with 500 MHz but at a decreased range. That’s happening…
What every engineer should know about IEEE 802.3bt PoE
Power over Ethernet (PoE), a networking feature defined by the IEEE 802.3af and 802.3at standards, enables Ethernet cables to supply power and data simultaneously to network devices over an existing data connection. Approved on September 27, 2018 by the IEEE-SA Standards Board, the IEEE 802.3bt standard lets significantly more power to be passed over the…
