The NX-E1 is the world’s first spectrum-scalable point-to-point digital radio that can deliver 2048 kbits of data in as little as 400 kHz of channel bandwidth. Advanced modulation and digital processing techniques allow one radio to deliver user-defined rates from 64 kbps to 8/34 Mbps in user-selectable bandwidths of 25 kHz to 7 MHz. Built-in Network Management and complete diagnostics minimize installation and maintenance costs.
