900 MHz and 2.4 GHz Spread Spectrum


 jump to related pages

The DGR 115 R and W series of spread spectrum transceivers is available in a ruggedized professional series of enclosures, at both 900 MHz and 2.4 GHz.

The new transceivers are more compact, use standard N type RF connectors, and are available in waterproof and non-waterproof versions. The 900 MHz series are also completely compatible with all other 900 MHz FreeWave transceivers, allowing easy expandability and upgrades.
