900 MHz

FHSS

Transceiver

Module

WIT910M2 transceiver modules are designed to transmit serial data using highly robust 900 MHz

frequency hopping spread spectrum (FHSS) technology. WIT910M2 modules employ RFM’s

beacon-synchronized CSMA at an RF data rate of 172.8 kb/s to support a high number of remotes.

WIT910M2 transceivers are suitable for both point-to-point and point-to-multipoint networks. FHSS

technology provides strong immunity to both interference and multipath fading. The small size, light

weight and low power consumption of these transceiver modules make them suitable for a wide

variety of applications. WIT910M2 modules are certified for unlicensed operation in the USA,

Canada, Australia, Israel and New Zeland.
