Maintain Dispatch Autonomy and take advantage of Regional Public Safety Resources – The Wake Forest Story

For Wake Forest, it started in 2007, when Forsyth County and the City of Winston-Salem Wake Forestcompleted a trunked digital 800 MHz public safety grade radio network and offered to lease radio frequencies to Wake Forest. The department accepted the offer because using the same radio system allowed interoperability, and soon its police and EMS transmissions were on the 800 MHz system.

As the system was used, however, gaps in radio coverage began to appear on campus and became more apparent daily, particularly when the radios were used indoors. Many of the school’s concrete and brick buildings were impenetrable by the 800 MHz radio waves, so the radios were often inadequate when the officers found themselves needing to use their portables indoors.

To solve the problem, Wake Forest investigated having their own radio system, however they did not want to give up access to the regional 800MHZ service.

An article here in Campus Safety Magazines describes the innovative solution – from Catalyst, of course!

Catalyst Propulsion and Simoco DMR Tier III Radios  

Propulsion Console

Propulsion is a graphics rich, critical voice dispatch console for Simoco Tier III radios that provides advanced communications with these radios through the DMR console standard AIS wireline interface. In addition, the console supports a variety of additional standards based and manufacturer proprietary radio interfaces including Project 25 (P25)Common Air Interface (CAI) and Fixed Station Interface (FSI), Digital Mobile Radio (DMR), SmartNet™, EDACS™, LTR, Verizon Push-To-Talk, MDC 1200 and more. Interoperability between radio systems is achieved, and migration from legacy radio systems to Simoco DMR can be easily and thoughtfully managed.

This touch screen compatible, infinitely configurable user interface displays Unit ID, Emergency, and Call History.  Dispatchers can simulselect or patch up to eight channels with intuitive graphical controls, instantly transmit on each module, uniquely set the volume for each module, differentiate audio on select and unselect speakers, and replay recent calls with a single click.  Each agency can add custom graphics to accelerate recognition of who is talking.

Communications between console positions and radios occurs through Radio over IP (RoIP).  Propulsion routes voice and messaging across your organization’s existing computer network using Internet Protocol (IP).  Dispatch positions and interoperability management can be established virtually anywhere on the network including across low bandwidth links like satellite. A peer-to-peer architecture allows communications to keep flowing when a controller or console is off-line.  Bottlenecks are eliminated, reducing connectivity costs and providing reliable voice traffic.

Propulsion Consoles communicate with Simoco Tier III DMR radios through the DMR standard AIS wireline interface. The console also has Session Initiated Protocol (SIP) and Real Time Protocol (RTP) technology which provides interoperability with a wide variety of complementary communications tools including IP Telephones, Collaboration solutions, tablets, etc. Connectivity between these devices, Simoco Tier III radios, radios from other manufactures using different protocols including Project 25 (P25), Digital Mobile Radio (DMR), EDACS, and EIA tone control, and your Dispatchers, can occur over your existing Internet Protocol (IP) network. The Propulsion console is compatible with routers, switches, and other network equipment from a variety of network equipment manufacturers.

Through the DMR Standard AIS Console Interface, Dispatchers have advanced communications with Simoco Tier III radios including:

  • Talk Group selection
  • Unit ID with centralized alias database
  • Emergency Display
  • Patch
  • Simulselect
  • Individual Volume Control
  • Integrated call logs, exportable for billing, analysis, etc.
  • Tone and voice alerts
  • All Call
  • Messaging
  • Control of Auxiliary IO at the Gateway
