Support for factory programmable worldwide ISM 2.4 and 5GHz radio bands (2.4GHz and 4.9-5.8 GHz) and output power allows a single product design to meet the certification requirements of multiple markets. The unique Smart Channel feature permits the solution to select an uncongested channel in the available ISM bands to avoid collision with other co-site wireless equipment.
