Transceiver OEM
Module
Combining 900MHz frequency hopping technology and 500mW of transmit power, the WIT910 is the latest
in a long line of wireless OEM transceiver modules from RFM. With the same physical dimensions of the
industry-leading WIT2410 module, smaller than a business card and just 8.6mm thick, the WIT910 provides
immunity to both jamming and multipath fading. The WIT910 also provides a low power consumption mode
suitable for battery operation.
