Solves POC's core weakness — no signal, no radio — by bolting on an 8-watt analog VHF/UHF transmitter as a fallback. Cellular carries daily nationwide range; analog kicks in when you're off-grid or towers are down.
Off-roaders, disaster-preparedness users, and anyone who needs POC's range on a normal day but can't accept a radio that goes silent the moment cell coverage does.
The most honest answer to 'what if the network goes down' in this category. If you've been debating POC vs. GMRS, this device is the case for not choosing — it gives you both in one unit.
