[NLRS] 915 MHz ISM Band and Digital Modes

Since David Palm asked a 902 MHz related question, I thought I would ask a
another question about 33 cm.

Are any of you doing any work with digital messaging or beacons up at 915
MHz?

Since as amateurs we are able to use the ISM band in ways that unlicensed
makers cannot, this has been an area of recent interest for me as a number
of microcontroller designs utilizing the RFM69HCW -
http://www.hoperf.com/rf_transceiver/modules/RFM69HCW.html have appeared
lately.

For general wireless communication between microcontrollers, 915 MHz works
far better than 2.4 GHz WiFi, BLE, or ZigBee do around your home/office,
and 915 devices are much easier on battery/solar power.

For the amateur who might already have 33 cm loopers and amplifiers, the
use of these small devices opens up some interesting possibilities for very
little investment.

Thoughts?
