Our series of Tait Radio Academy lessons on P25 continues, this time looking at the difference between P25 Phase 1 and Phase2. This course is taught by Andrew McTaggart, a Customer Support Engineering Specialist at Tait Communications. Prior to that, he was a product trainer on P25 digital radio communications equipment.
A question commonly asked is, “What is the difference between P25 Phase 1 and Phase 2?”
One of the original goals of P25 was spectrum efficiency. The radio spectrum is a limited resource. There are only so many radio channels that can be licensed in a given area.
