Can your wireless network meet the demand for capacity and coverage in a harsh environment?

Increasingly, commuters everywhere expect seamless high-capacity wireless service as an integral part of their lives. Staff and public safety personnel also rely upon wireless networks to do their jobs and maintain a safe environment. Staying connected with business associates, friends, family, and media is part of nearly everyone’s daily routine. No matter what carrier they subscribe to, a fast, dependable connection is expected throughout a subway’s harsh, subterranean environment.

Custom solutions

Each building is different, so your solution is engineered to suit your building. 5G, Internet of Things (IoT), and Private Cellular Networks leveraging the Citizens Broadband Radio Service (CBRS) are all part of the SOLiD solution.


Every leg of a subway, train depot, and wing of an airport terminal is different. Today’s commuters and travelers demand uninterrupted wireless connectivity whenever their journeys lead them to a mass transit hub and points beyond.

Airports present a special set of challenges with their expansive terminals, high ceilings and other wide-open areas. While subways and railways often weave through harsh environments, the prevailing passenger demand for connectivity remains. And when travelers are stuck on a layover, waiting for the next train or racing down the corridor to their next flight and business meeting, they are also inundating wireless networks with voice calls and data, scrambling for those on-the-go updates and bursts of productivity.
