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.
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.
