Introduction and Overview
Overview
The SEL-3031 is a 900-MHz, license-free, spread-spectrum radio. The radio operates
in the ITU Region 2 ISM band of 902–928 MHz using a fast frequency-hopping
algorithm for noise immunity and long-distance operation.
The SEL-3031 prevents the need for multiple sets of radios or expensive dedicated
fiber transmitting over long distances. Figure 1.1 shows the flexibility of the SEL-3031
