Features:
• High speed wireless serial data
• Robust 2.4 GHz frequency hopping
• 3.3 volt operation
• Small size, light weight
• Certified for unlicensed operation in the
WIT2450M2 low-cost transceiver modules are designed to transmit serial data using robust
2.4 GHz frequency hopping spread spectrum (FHSS) technology. WIT2450M2 modules employ
RFM’s beacon-synchronized CSMA at an RF data rate of 460.8 kb/s to support a large number
of remotes. WIT2450M2 transceivers are suitable for both point-to-point and point-to-multipoint
networks. FHSS technology provides immunity to both interference and multipath fading. The
small size and light weight of these transceiver modules make them suitable for a variety of
applications. WIT2450M2 modules are certified for unlicensed operation in the USA, Canada
and Europe.
