Distributed antenna systems offer venues a way to provide safety and security measures, enabling first responders to have quick, clear radio communication within any given space. Using distributed antenna systems, a public-safety network can be deployed within a building or other venue. Distributed antenna systems increase and extend mobile coverage and capacity ensuring there are no dead zones within a venue that would prohibit first responders from doing their jobs.
When considering network design for a public-safety network, there are a few important things to determine.
First of all, find out if your municipality or city has ordinances in regards to distributed antenna systems and the network design of any public-safety network. You may be required to pass a public-safety network test, or otherwise meet regulations.
You also must meet National Fire Protection Association (NFPA) and International Fire Code standards for your public-safety network, which will ensure the reliability of your distributed antenna systems network design. You may need to have a fully waterproof installation, for example, or use a backup system for your network, depending on what distributed antenna systems you use.
Redundancy is important within a public-safety network, which is different from your typical commercial distributed antenna systems network design. For public safety reasons, you also need to consider how to defeat interference and integrate handset power control and coverage standards into your network design.
Generally speaking, it is wise to separate a public-safety network from any kind of public or commercial distributed antenna system, as each system may have vastly different requirements for network design. Trying to combine the two can lead to unnecessary costs and complications. Also, you will want to have your public-safety network fully accessible to emergency workers, something that becomes complex if there are public or commercial users on the system. This means the infrastructure itself should be different and separate, with maintenance and user access strictly controlled so there is no unwanted crossover.
To make network design easier for a public-safety network, take a look at all of the standards you must meet, and establish what equipment will do that job safely and reliably. Set up your public-safety network separately from any other distributed antenna system you are running, and make sure you maintain the system.
