The RF Xbee-pro 900HP is ideal for smaller power consumption, from point to
multipoint on low latency net application. It is used on peer to peer and net from point
to multiple point. The XBee-900 module has a higher selectable transmission power
of 250 mW. This higher Tx power allows a line-of-sight range up to 28 miles with
antenna right. This one is ideal for situations in which the RF penetration and absolute
transmission distance are of extreme importance for the implementation.
As part of the RF XBee line, this module is easy to use, includes drop-in gateways
nets, and uses Digi and Adapters. The RF does not need any out-of-the-box
configuration and any necessary advance configuration can be replaced with simple
commands.

In the specific case of Peru, the modules were configurated to work on a 915,5 a 927,7
MHz frequency, setting the cm register (Channel Mask) with a value of
FFFFFFFE00000000, that same value is defined during the production of mag-100R and
it is storage on the inter flash of the XBee 900-HP.
The starting process of the Mag-100R is configured following the next steps. If the XBee
900-HP radio module is changed, then the correct configuration is ensured.
