Product Overview

The new full rate LEDR microwave radio family provides full duplex, scalable bandwidth and capacity from 1 x E1 (2.048 Mbps) in a 500 kHz channel to 4 x E1 (8.192 Mbps) in a 2.0 MHz channel. These radios are designed to operate in a point to point environment with a wide range of applications. They are especially effective for telecommunications access and transport links, and for use as backhauls to extend existing telecommunication channels. The full rate LEDR microwave radio is designed to connect to any industry standard E1 G.703 source.
