How far can licence-free two-way radios communicate?

The maximum communication distance depends heavily on your surroundings due to the lower 0.5-Watt power limit:

• Open Spaces & Countryside: You can expect a range of around 3 to 5 miles (5 to 8 km), and sometimes even further if you have a direct line of sight from a high point like a hilltop.

• Built-up Areas & Cities: In urban environments with concrete buildings, trees, and vehicles, the range drops to roughly 0.5 to 1 mile (1 to 1.5 km) because obstacles block the radio signal.

• Indoors: Inside a typical office, school, or retail environment, they easily cover up to 10,000 square feet or across several floors.
