Harris P25 VDOC Site Configuration

The Harris VDOC (Voice/Data on Control) solution provides public-safety personnel with trunked radio coverage in locations with limited available frequencies. This lets users take advantage of Project 25 features at a significantly lower cost than a multi-channel trunked site, according to the company VDOC sites typically consist of one to three RF channels and are integrated into multisite P25 networks. www.harris.com
