Coverage/Interference

How to minimize the effects of time-delay interference

In this article, we examine ways to minimize TDI’s effects, which will cripple system performance — even when excellent RF coverage exists.

A look at time-delay interference

Does your simulcast radio system seem to exhibit improved range and performance when certain transmitters are turned off? In almost every case, this is an indication of improper system operation and that your system needs on-site optimization.

Listen up–Understanding the decibel

Here’s a primer on the decibel, which makes the work of every radio engineer and technician far easier.

Firecom introduces second-generation wireless headset, offers credit on older models (with related video)

Firecom’s 50-Series is a second-generation, full-duplex, hands-free wireless radio headset that reduces the need for firefighters to be tethered to the truck and intercom via a cable.

NIST tests firefighter tracking devices for radio-frequency interference

RFID poses serious potential for wireless interference with PASS device alarms, NIST researcher Kate Remley said.

Survey Technologies’ Field Test measures in-building coverage

STI Field Test 6 supports indoor coverage surveys using a scanning receiver, a compatible spectrum analyzer, or a digital radio test set.

Winning the battle

Last month, we began to explore radio-frequency interference, every technician’s bane. Now we look at additional causes of RFI and — more importantly — what can be done about them.

The bane of your existence

Radio-frequency interference is something that every radio-system engineer will encounter, sooner or later. In this installment, we begin to explain how it occurs and what to do about it.
