CommSite has recently rolled out the new “E” series Motorola MotoTRBO range of radios incorporating all the latest digital radio enhancements into an underground tunnel environment to provide an improved level of safety for the operational staff. The new DP4000e series portable radios provide location information both from on-board GPS when outdoors and from Estimote iBeacons when indoors or underground in tunnels, returning the data to the Trbonet console in the control room. This provides the console operators with an instantaneous, accurate location in an emergency or man down situation. The portables are also UL rated for hazardous areas and utilise the on-board WiFi capability for remote upgrades. This is an exciting project allowing us to bring the latest in Motorola’s digital radio technology to a major water utility to vastly enhance their personnel safety and work group efficiency.
