With more agencies moving to digital voice systems, are police officers in danger of losing a signal because of the Cliff effect?
Cliff effect
In telecommunications, the (digital) cliff effect or brickwall effect describes the sudden loss of digital signal reception. Unlike analog signals, which gradually fade when signal strength decreases or electromagnetic interference or multipath increases, a digital signal provides data which is either perfect or non-existent at the receiving end. It is named for a graph of reception quality versus signal quality, where the digital signal "falls off a cliff" instead of having a gradual rolloff.
