Which Phone Fits Your Needs? 5.8GHz? DECT 6.0?

By Staff Writer, 09/07/72

Telephone technology has come a long way from the days of corded phones. Thanks to the latest technology, the sound and security of cordless phones now rivals corded models — in conveniently portable handsets.

Corded phones operate on various radio frequencies which are set by the Federal Communications Commission (FCC). The two latest technologies on the market today are 5.8GHz and DECT 6.0.

Digital 5.8GHz is one of the most advanced cordless phone technologies available. Transmitting on a new, open frequency with long-range and crystal-clear sound, these phones are less likely to interfere with wireless networks and have excellent, encrypted security. 5.8GHz frequencies often escape most wireless interference from wi-fi networks, resulting in a clean and clear signal.

DECT (Digital Enhanced Cordless Telecommunications) 6.0 operates on the 1.9GHz frequency and boasts excellent sound quality. Wi-fi friendly, this technology easily integrates into homes with wi-fi and Internet services because the 1.9GHz frequency is exclusive to DECT, making it interference-free (from routers, cell phones, wi-fi cards, etc.) for cordless communications. Though new to the United States, this frequency has been used for years in Europe. Enjoy improved voice clarity and crystal-clear digital sound as well as longer battery life. Extra handsets even let you make calls to other handsets in the house. DECT is a digital wireless phone technology that could make cordless phones much more common in businesses as well as homes.

Analog: Yesterday's News

Analog technology is common and inexpensive, and benefits compared to digital are few. Digital technology allows phone signals to sound clearer and also offers increased security, while analog cordless phones use older technology, resulting in just average sound, range and security. And, analog signals can be picked up easily and interpreted by radio scanners.
