System Overview
The Wisconsin Interoperable System for Communications (WISCOM) is a 9600 baud Project 25 (P25) Phase 1 digital VHF Trunked Radio System (TRS) that will provide interoperable communications to public safety in the State of Wisconsin.
The initial build-out will commence during the first half of 2010, with completion by the end of the year as stipulated by the federal Public Safety Interoperable Communications (PSIC) grant being used to build the system.
Hardware
The RF site equipment will be supplied by EF Johnson Technologies Inc. (EFJ) of Irving, TX. Each site will have four (4) frequencies using EFJ 3800 series digital repeaters. This equipment is part of EFJ's IP25 technology and each repeater contains it's own trunking controller.
The EFJ system will be a distributed network with de-centralized call routing, meaning there is no "central controller" overseeing PTT requests and TG access. Each site handles these needs on it's own. There will be some "central" servers with a user database and the like, but it's up to each site to grant system access.
