2.4GHz Cordless Phone Frequencies
Third generation 2.4GHz cordless phones have been allocated the frequencies between 2.4Ghz and 2.4835Ghz, with a channel spacing of 5MHz.
The 2.4GHz cordless phone frequencies are shared with 802.11b and 802.11g wireless networks.
5.8GHz Cordless Phone Frequencies
Fourth generation 5.8GHz cordless phones have been allocated the frequencies between 5.725Ghz and 5.850Ghz.
It is important to note that some 5.8GHz cordless phones use the 5.8Ghz frequencies only for base-to-handset transmissions, while still using the 2.4Ghz frequencies for handset to base transmissions.
This split-frequency technique saves batter life on the cordless phone handset, because it requires more power to transmit at the higher 5.8GHz frequency than at the lower 2.4Ghz frequency.
The 5.8GHz cordless phone frequencies are shared with 802.11a wireless networks.
