Clearer Cordless Connections

Techstination feature for Wednesday, January 29, 2003

A clearer connection from cordless phones. Bloomberg Boot Camp, a report on today's technology. Go shopping for a cordless phone these days and the choices can be pretty confusing. There are 900 MHz models... .2.4 GHz models... and now others that use 5.8 GHz technology. What's the difference? The main one is 5.8 models let you escape from frequency clutter. At Uniden America, President Al Silverberg puts it this way...

"Well it means the telephone is going to act the way it's supposed to act. When you pick up the phone, make a call or receive a call and you walk around the house or yard you're not going to have interference issues if you turn on your microwave oven or someone else in the house is using the home networking equipment, or if you have a 900 MHz phone, you're not going to have interference issues with baby monitors or other cordless telephones."

A 2.4 GHz phone isn't recommended near the kitchen or in the vicinity of 802.11b wireless networking equipment. New 802.11a equipment operates at 5.2GHz... but...

"In radio spectrum there's a huge difference between 5.2 and 5.8, so there's really no interference issues at all."

The problem with the 5.8 GHz phones on the market, from Uniden, Vtech, AT&T, Panasonic and others right now is price. Like all new technology... it's expensive because it's new, typically 150 dollars or more. If you don't have interference issues, a 30 dollar 900 MHz model works fine.
