Cordless Telephones: Use, Differences, And Security

Cordless telephones refer to telephones that consist of a base and a handset. A radio signal is transferred between the base and handset during the phone call. This allows for use of the phone at a longer range (typically 100 meters) than a phone with a cord, and prevents tripping over the phone cord.

Batteries must be charged for at least 12 hours, and 24 hours is typically recommended. Not giving adequate time for batteries to charge will shorten the lifespan of the battery and result in subsequent charges not being as full.

A lot of uncertainty exists regarding whether high or low frequencies are better for use. Some argue that use of higher frequencies leads to higher audio quality and better range. This does not appear to be the case, since higher frequencies can lead to poor reception after a relatively short distance. Using a higher frequency may also interfere with other items using this frequency band, including microwaves, baby monitors, and wireless routers.

Security features have been designed in order to limit the risk of eavesdropping. With phones that do not have any security features to protect against eavesdropping, a radio scanner can be used to listen into a conversation. However, DSS (Digital Spread Spectrum) spreads an audio signal over a wide range of frequencies in random pattern. The receiver and base are both able to decode this pattern. However, a radio scanner will not be able to listen into a conversation.

Cordless telephones are useful technology that can make talking on the phone much easier, since you are not limited by the length of the cord. Understanding the differences in frequency bands can help with purchasing the right phone. Make sure to purchase a phone with added security features, such as DSS, that will prevent others from listening in on your phone conversations.
