Building Code Compliance Connectivity Testing

There are a wide range of fire codes and building permit requirements across the nation, but for public safety radio coverage some of the most commonly shared baseline requirements for wireless grid testing are maintaining the following

  • Signal strength measurement of at least -95 dBm is considered passing in that grid.
  • Passing coverage must be in 90% of the squares.
  • If adjacent squares have failing coverage, a DAS will be required.

It is possible depending on the policies in place in certain locations that buildings may require a DAS installation even with complete coverage depending on square footage.

Cellular connectivity coverage, while important for a optimal functionality, is not included in these requirements.

Commercial Cellular Connectivity Testing

While not always legally required, having total coverage for cellular connectivity is becoming more and more vital to the functioning of a business every day.  Our professional team will test for dead-spots and areas of weak connectivity to all cellular carriers.  As interference with wireless connectivity grows getting your cellular connectivity analyzed with wireless grid testing annually or biannually is becoming more and more important to determine what, if any additional systems are required to maintain optimal connectivity.


We’ve answered some of the most common questions about grid testing of wireless connectivity here, but if you don’t see your question, just ask and we’ll be in touch.

Is grid testing of wireless connectivity required?

For most businesses wireless grid testing for public safety radio coverage is required by the local authority having jurisdiction like a fire marshal.  Fire code and building inspection codes for building permits require regular wireless grid testing to maintain compliance.

What is actually tested with grid testing for wireless connectivity?

RFE Communications has expert technicians who are certified to test your location for everything from wireless connectivity for public safety radio systems, to cellular signal connectivity levels, to even LMR (Land Mobile Radio) connectivity.  Technicians walk every foot of your property performing thousands of tests and analyzing that data to provide you a detailed coverage map.

Is grid testing part of the installation process?

No, grid testing of wireless connectivity is not part of the installation process.  This is a service businesses will want to do before making any decisions about installation.  In fact it may even be determined through grid testing your facility already has complete coverage and doesn’t need any kind of DAS or other booster systems, in which case testing provides customers peace of mind that they will meet building code requirements.
