Radio Frequency Interference Best Practices Guidebook   [open pdf - 2MB]

From the Executive Summary: "Public safety voice and data communications are continuously at risk of radio frequency (RF) interference, which is defined as 'the effect of unwanted energy due to one or a combination of emissions, radiations, or inductions upon reception in a radio communication system, manifested by any performance degradation, misinterpretation, or loss of information which could be extracted in the absence of such unwanted energy.' RF interference can impact a variety of commonly-used wireless technologies such as land mobile radio (LMR), Long-Term Evolution (LTE), Bluetooth, Wi-Fi, and Global Positioning Systems (GPS). Both manmade and natural sources can generate undesired signals that may cause RF interference capable of disrupting wireless communications, including 911 calls, essential LMR or LTE communications between first responders, and navigational systems using GPS or other satellite-based location services. To mitigate possible risks to public safety communications, SAFECOM and the National Council of Statewide Interoperability Coordinators (NCSWIC) developed the 'Radio Frequency Interference Best Practices Guidebook' with the support of the Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security Agency (CISA) and the Science and Technology Directorate (S&T) to educate public safety organizations on RF interference threats."
