Telecommunications Program purpose: Provide reliable telecommunications for public-safety and transportation efficiency. Specifically:
- Provide WYDOT with one-stop-shopping for telecommunications, exchanging voice, data and video information between distant locations on shared telephone, microwave and mobile radio infrastructure.
- Give balanced telecommunications service and support to all customers, including other agencies as appropriate, and to meet responsibilities with due priority.
- Provide technical integration and support of electronics systems in DOT vehicles and on Wyoming roadways.
- Provide system architecture expertise for connecting distant information systems using appropriate communications.
The Telecommunications Program maintained WYDOT’s sophisticated telecommunications systems at very high levels of reliability, averaging 99.9% for mission critical communications. We performed preventative maintenance and technical inspections of Telecommunications Infrastructure – all 222 individual infrastructure assets were confirmed to be in Acceptable to Very Good condition. Our critical radio systems include public safety radio repeaters, microwave communications, dispatch consoles, and telephone systems; as well as WYDOT building wiring, data communications to roadside devices, and more than 2,000 mobile/portable radios.
“WyoLink” is Wyoming’s statewide, public-safety, interoperable radio communications system. The Telecommunications Program finished several more WyoLink core sites: 53 of the 55 planned core sites are providing service to about 112 Local, State and Federal public-safety agencies. Work continues to acquire property or leases, and finish construction of the remaining core sites. Also, WyoLink Portable Coverage Enhancement sites are drastically improving WyoLink handheld radio coverage for local agencies in six municipalities; work is underway on six more designated sites. The project has enjoyed growing participation from Wyoming public safety agencies. Continued Legislative funding for ongoing support and regular update services is being sought.
The Telecommunications Program worked to optimize WYDOT’s use of WyoLink mobile and portable radios for all operations, including evaluation of coverage gaps, training, and reconfiguration of radios. We met FCC “narrowband” requirements by very complex coordination of our staff and technicians’ work, spectrum licenses, and customer-agency notifications.
We continued to improve WYDOT’s statewide telephone network with four upgraded phone switches connected to the centralized phone system statewide, which gave remote WYDOT offices improved performance and features, made voicemail available and reduced equipment costs by half. We connected extraordinarily hard-to-serve WYDOT shops, like Burgess Junction, with WYDOT wireless Internet Protocol voice and data communications. We cut cost and improved capacity and effectiveness by replacing conventional T-1 circuits with advanced Metro-Ethernet technology, which will avoid $108,000 annually in WyoLink dedicated circuit costs.
The Telecommunications Program supplies expertise necessary for progress on many projects that require roadside data communications, coordinating with other programs. We expanded the Internet Protocol Backhaul network over the digital microwave backbone, for more mission critical broadband data communications along Wyoming highways.
