Alabama Public Television awards TSG to upgrade its microwave network

Technical Service Group (TSG) has been awarded with the bid to upgrade the microwave distribution system for Alabama Public Television. The company will support ATSC 3.0 transmission in 30 locations with bi-directional and IP components from Vislink. The project is valued at approximately $2.8 million.

The APT network utilizes nine transmitters and 21 repeaters to maintain statewide coverage. The master signal originates from the network operations center at APT’s flagship station, WBIQ, in Birmingham, Ala. To achieve bi-directional connectivity and full redundancy across the entire network, TSG will install 120 Vislink’s transceivers, the IPLink 3.0 – four at each site.

Vislink’s digital video microwave system will allow APT to transition from traditional ASI transport to an IP-centric system architecture. The new system will also utilize Simple Network Management Protocols (SNMP), which will monitor and manage the overall health of the APT network.

“Before we could upgrade to an ATSC 3.0 on our transmitters, we had to have an IP network over the microwave system designed to handle an ATSC 3.0 signal,” explained Windell Wood, director of engineering and COO for APT. The current system has been in place since 2010, and is only capable of supporting ATSC 1.0.

“Alabama has one of the best public television organizations in the country, with one of the most robust microwave infrastructures,” said Mickey Miller, CEO of Vislink. “We have worked with APT for more than 20 years, and we’re proud to continue our relationship as they prepare for an ATSC 3.0 migration and move toward a total IP-centric network. TSG is an incredible company that provides great technical solutions, and we value our collaboration.”
