Deployed: Delivering Backhaul for Mobile Public Safety 4G LTE Networks


Public safety officials are often plagued by constant communications interruptions due to overwhelmed cellular towers during major events, and disaster scenarios. These occurrences cause an immediate influx of cellular traffic that would cripple most towers in the area, leaving public safety officials without critical communications.

What these officials needed was a public safety communications solution that would remain operational, despite how many carrier towers buckled under immense use. First responders required a solution that was efficient and flexible, allowing them the freedom to use the solution to communicate through voice, video, photos, or chat.

Although the FirstNet 4G LTE network has been a valuable coordination and communications tool for many agencies, there’s still a need in delivering a flexible communications infrastructure that can expand and contract operationally as the need arises; to deliver critical communications when and where it’s needed most.


BATS utilizes the BTS platform to design a nomadic wireless backhaul link that is able to meet the bandwidth requirements needed for real time voice and data communications for mobile LTE network Cell-on-Wheels (COW) deployments. The links are typically achieved by placing dedicated point to point (PTP) radios, like the Cambium PTP650, on both sides of the link to transport high-speed; low-latency voice and data communications.

One BATS BTS 50 system paired with a PTP radio serves as a mobile backhaul node atop a public safety COW. A second BATS DVM 50X (or similar) system paired with another PTP radio is placed in a base station location overlooking the entire operational area.

This arrangement allows for operators in the area to extend the existing wireline infrastructure at the base station location, wirelessly, to mobile LTE sites up to 30 miles away; filling a major telecommunications gap for event communications.

BATS’ innovative antenna alignment and stabilization technology allows for an efficient arrive-and-connect workflow, eliminating the need for technical resources or extensive planning in rolling out a flexible public safety network.

Solutions similar to this have delivered 95 Mbps or more of aggregate throughput, allowing operators free and uninterrupted use of their Public Safety LTE handsets for ongoing coordination and safety efforts.
