DAS and Public Safety
Adding Public Safety Services To A Das
In many municipalities across the country, legislation is in the works to require buildings to meet a minimum signal requirement for public safety first responders inside the building. There are two ways to meet this requirement, either the building has sufficient coverage from the outdoor repeater sites, or the property owner must enhance the service using a Distributed Antenna System (DAS). If you are already planning on installing a DAS in your building, it is a good idea to make sure it will support public safety channels in case they are needed in the future.

Survivability Requirements
A public safety DAS is useless if it isn’t operational in the event of a disaster. For this reason, public safety agencies usually have more stringent requirements for survivability than WSPs. These may include centralized power with battery backup, installing cables in conduit and equipment in NEMA enclosures. All of these items are difficult and costly to retrofit, but relatively easy to incorporate in the initial system.
If you are feeling overwhelmed by all of these new requirements for your DAS, the best thing to do is contact an expert. Planning ahead will avoid many problems down the road if you need to add public safety channels to your DAS.
