What is iDEN?
iDEN is a trunked, digital radio system, most commonly found as the PTT/Direct Connect service of the Telus Mike and Nextel systems. Used mainly by businesses as a hassle-free and low-cost radio dispatch solution, it is used by a handful of police services as their primary radio system (Durham Regional Police, for example use radios on the Telus Mike system). iDEN cannot be monitored with a scanner. A large 900 MHz iDEN system is used by non-public safety workers at Pearson Airport.
