Radio Interference From Multiple Users On The Same Channel
Learn how overlapping radio coverage causes co-channel interference and how exclusive UHF frequencies help deliver clearer LMR communications.
Methods of Data Transport
Explore GPS data network design, from cellular and conventional radio to digital systems, with key pros, limits, and tracking options.
Signaling Methods for Radio Systems
Explore the evolution of radio signaling methods, from burst tones and CTCSS to advanced digital paging and remote control standards.
Controlling Antenna Site Interference
Antenna site interference is a problem that has plagued the Land Mobile Radio communications business since the inception of two-way radio. There are techniques for operating a clean antenna site so that each radio operates with little to no interference from each other at the site. When properly implemented, these techniques can also reduce or eliminate interference from other radio sites.
Conventional Radio
Explore the evolution of land mobile radio systems, from simplex and repeaters to CTCSS, simulcast, scanning, and interference solutions.
LTR Trunking
Learn how LTR trunked radio systems work, from channel pooling and reduced blocking to repeater architecture, history, coverage, and features.
