Case Study: Simulcast Expands Channel Availability and Cuts Expenses for Public Safety

For those agencies considering P25 for the future, Carlson’s Trailblazer offers the perfect migration path because the system allows for both IP and TDM analog


“One of the other things I like about the Trailblazer is it offers the best of both worlds,” says Adams. “We can have analog, true TDM, fixed latency, microwave, with a little bit of Ethernet. We only use a portion of the Trailblazer’s 512 KB bandwidth for connectivity to different sites to do diagnostics requiring Ethernet.”

As many as 10 Trailblazers have been placed at a site with almost no degradation, because CommTech found a way to successfully eliminate localized interference by using the Trailblazer to spread the usage over various frequencies.

For those agencies considering P25 for the future, Carlson’s Trailblazer offers the perfect migration path because the system allows for both IP and TDM analog. If it was being used for analog simulcast and then the agency switched to P25, they could change over the bandwidth to IP and use it to migrate to P25. However, since most agencies using an IP backhaul need higher bandwidth capable of supporting extensive data, such as video traffic cameras or other streams, Carlson also offers its LongHaul family of IP bridges for that purpose.

But for CommTech, the Trailblazer fits its needs “to a T.”

“Carlson’s Trailblazer has found its niche in analog simulcast because it is a true TDM radio. It does exactly what it’s supposed to do,” says Adams. “It does fixed latency backhaul for analog communications, and it does it quite well.”
