1. 9XTend USB RF Modem
The 9XTend RF Modem affords OEMs and integrators an easy-to-use RF
solution that sustains reliable delivery of data between remote devices.
Out-of-box, the modem is configured to immediately sustain long range
wireless links between devices. Simply feed serial data into one modem
then the data will surface on the other end of the wireless link. The modem
transfers a standard asynchronous serial data stream between devices,
features 256-bit AES encryption and sustains up to 115.2 Kbps data throughput.
