AI Overview
4G PoC (Push-to-Talk over Cellular) radios offer nationwide or global instant communication by using cellular data networks and Wi-Fi, bypassing the range limitations of traditional radio. They operate with a PTT button, often using apps like Zello, and require a SIM card with a data plan. Popular models include Retevis L51/L61/L71, RadTel P8, and Motorola Wave TLK110.
This video explains the basics of how PoC radios work:
