in homes that cause interference with these phones. Telephones of this frequency are available in analog and digital. Multi-line telephones in analog and digital style cordless phones are also available for busy homes or offices. 2.4 GHz telephones are not without fault. They do have some interference issues. Some wireless headphones, wireless game controllers and microwave ovens can cause static. The biggest interference issues with 2.4 GHz telephones are wireless computer home networks (WLAN). For those people who want the safest phone but do not have wireless systems to interfere with the cordless phone, DSS technology is available. Ultimately, a 2.4 GHz cordless phone will give you better clarity and increased security. It certainly is a better choice for those who have too much interference with a 900 MHz cordless phone.

Once again, the FCC determined that the 2.4 GHz is overcrowded and opens another bandwidth: 5.8 GHz. This higher bandwidth shares many of the same characteristics of 2.4 GHz with one exception. 5.8 GHz telephones will not receive interference from wireless home networks, wireless game controllers or wireless head phones. The 5.8 GHz bandwidth is still above the spectrum for interlopers who use scanners to pick up cordless phone conversations making for better security than 900MHz phones could offer. Like 900MHz and 2.4 GHz, 5.8GHz is available in analog, digital and DSS forms. Something that should be taken into consideration when purchasing a 5.8 GHz telephone is the battery life. Higher frequency telephones use more power than lower frequency telephones. Companies have compensated for this by using dual bandwidths with their higher frequency cordless phones. To make sure that these cordless telephones have a decent battery life the 5.8 GHz frequency is only used for base-to-handset signals. Then for handset-to-base transmissions the 2.4 GHz frequency is used. Since both frequencies that are used are above the range for scanners to pick up there is less risk in using both frequencies.

Digital cordless telephones that operate on 2.4 GHz and 5.8 GHz are not as susceptible to interlopers. Scanners work on a bandwidth that is lower than 2.4 GHz. Therefore, they can not easily pick up conversations from phones on these higher bandwidths. Homes that employ many wireless devices might find 5.8 GHz phones to be better suited for them as they will not have as much interference as 2.4 GHz phones. Otherwise, 2.4 GHz phones are well suited for environments without wireless networks or many wireless accessories. All three frequencies of cordless phones are offered in analog, digital and DSS. The availability of these three frequencies of phones offers consumers any number of options based on their n
