Hi Simon,

Throughput will be highly dependent upon the RF environment and what
transceiver you are using. The M0+ most likely has enough power to do it
under ideal conditions, but retransmissions due to collisions will limit
the effective bandwidth.

You can use 900 mhz and 2.4 ghz transceivers with 15.4. ~900 is
significantly less crowded but lower theoretical bandwidth. The Atmel 212B
is 900 Mhz and specs 1000 kbps as the max air data rate.

Which transceiver are you using?
