There will *never* be free firmware for 3G cellular devices. At least
not in consumer devices as there are major legal issues with it. There
are USB 3G modems which aren't dependent on OS loadable firmware, but
that doesn't mean they do not have firmware.

Atheros is not going to release the code for ath10k. I know this because
I worked on getting the code released for ath9k-htc firmware. After a
loss of two key developers inside the company and management changing it
is no longer feasible to get the code. You need both management's
cooperation and the cooperation of developers. Neither are budging.
They're hostile beyond comprehension. They even moved key things out of
the driver and into the firmware so support for things like mesh
networking, packet injection, etc won't be possible.

We're hoping to convince another company to cooperate on 802.11ac. We've
made the right connections, but it'll still take time.
