  • CriticalPoint™ 700/800MHz Class A Fiber DAS
    Comba Telecom’s CriticalPointTM 700/800MHz Public Safety DAS is a Class A, fiber based signal booster solution. It is fully NFPA compliant and provides excellent in-building coverage for ERRCS, while providing the utmost in flexibility and reliability....

  • In Comba Telecom’s ongoing efforts to provide feature rich yet highly affordable solutions to facilitate in-building coverage for First Responder two way radio communications, Comba is developing a state of the art solution for campuses with multiple buildings or venues such as high rises that are too large to be powered by only a Bi Directional Amplifier. It is also a preferable alternative for projects that would otherwise require multiple BDAs or large wattage BDAs. Utilizing this distributed amplification architecture provides better coverage, a simpler to install infrastructure, and can lower your total project cost. This solution will also provide excellent performance, and advanced features that will make the solution future proof in the event of future NFPA and Public Safety ordinance requirements.

    This solution is based on digital signal processing and digital over fiber transmission technologies, and is focused on providing excellent coverage, system flexibility and reliability on a very affordable basis – while also assuring reduction of space requirements and operating costs.
