Conventional private mobile radio (PMR) is an inexpensive way for professional communications. The licencee pays a flat rate for the frequencies that are required. There are no further costs for unlimited airtime. The hardware is easy to use and very rugged. Riedel distributes Motorola‘s complete PMR product range including the Motorola GP-344, which features 16 channels and a battery life of up to 11 hours in a compact housing.
