Ok, I have ordered a four RT5370-USB adapters.
I am building a distributed wireless audio with shairport that will operate
4 nodes outdoors, plus a laptop. It will be running on four Rasp-Pi Zero W,
each equipped with a audio amplifier and Wifi-mesh through this external
adapter. The on-board WiFi could be used as an access-point.
So, Am I on the right track?
If the mesh your are building is very small and not very dense, this
may work, but really don't expect any performance or range miracles
from that Ralink Rt5370 1T1R USB Wifi, nor reliability... (I'm not
saying that the SDIO Broadcom on-board WiFi crap on those RaspBi boards
is any better)
Why are you so keen on using that toy hardware? Using of-the-shelf
WiFi routers is so much more convenient and even cheaper than using
those RaspPi boards + Wifi dongles... Any reason why it got to be those
boards (which neither has any fast IO interfaces to attach proper
wireless hardware, nor any decent networking capabilities itself)?
Cheers
Daniel
