AT&T 5.8GHz Cordless Accessory Handset

5.8GHz digital system: The 5.8GHz frequency-hopping spread spectrum technology operates on a different wavelength with much less traffic than 2.4 GHz technology, while maintaining the great security, incredible clarity and long range of that lower frequency technology.
