* HD Voice. While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD
Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives
voice a more natural sound, while the additional upper octave dramatically improves speech
clarity and intelligibility.
Wireless HD Calls. To take advantage of this extended bandwidth, both phones on the call
must support HD Voice, and both phones must be on the same carrier, in coverage areas
that support HD Voice.
