This buyer’s guide provides an overview of how different digital two‑way radio communication systems work. While a qualified two‑way radio service provider is an important partner in finding the solution for your team, this guide can get you started with your research.
Simplex — Radio‑to‑Radio
This method describes one radio talking to another radio on the same frequency, on either the 150 MHz or 450 MHz band. 150 MHz works well in open rural areas or suburbs. 450 MHz radio‑to‑radio works well in an urban environment, but its limitations become apparent in antenna height and radio power.
