Re: [ipwave] FCC Moves Plan Forward to Chop Up Vehicle Safety Airwaves

I think IEEE defines WLAN as IEEE802.11.
so any IEEE802.11xx standard can be called a WLAN standard.
http://www.ieee802.org/11/

also IEEE defines WMAN as IEEE802.16 technology, which was replaced by LTE
cellular technology.

FCC is pushing for 5G services/qualities to be achieved. I think it may
depend on locations/regions, because some locations may not have good
cellular communication signals.

I agree, they are pushing for that,
