Distributed Antenna Systems (DAS) Takeoff

Important

Complete emergency-systems-research before beginning takeoff.

[!info] See emergency-communications-systems for information about Emergency Responder Radio Communication Systems (ERRCS).

[!info] Cellular Systems Less common than ERRCS are "cellular DAS" systems
