actually ............ the " next " generation of cordless phones will be UWB phones operating in the 5 and 10 gig spectrum. ( with uwb , frequency is not specifically relevant , only the general band they operate on ) .. the " past " generation of cordless phones , operating at 2.4 gig hz , was discontinued by asian makers last year sometime ( or before for some ) , to tool up for the " current " generation of 5 gig digital ( all 5 gig phones are digital or spread spectrum ) cordless phone production. plain digital UWB transmissions are 10X more secure than the best spread spectrum radios / phones. consumer scanners could not detect spread spectrum phones and the new UWB radios will be MUCH harder ( 10X ) than spreaders to find. no known available radio equipment ( not even watkins johnson or Racal ) can detect UWB transmissions from a distance yet. ( even old watkins johnson could find spread spectrum carriers , tho not decode the digital modulation codec ) tho the military has had UWB radios deployed in certain applications for more than 10 years now , they have still NOT deployed surveillance equipment , in the field , which can detect UWB. rumors have it that a few communications eavesdropping satellites already have UWB capability ...... certain other people , in the know , say it's only use / response to the " current " deployment of military UWB radios and not general UWB eavesdropping equipment . more remains to be seen about military UWB .... probably be years before much gets leaked into the civilian sector about this state of the art equipment. type " UWB radios " or " UWB cordless phones " into Google for more up to date info ....... http://www.wi-fiplanet.com/tutorials...le.php/1598581 http://reviews-zdnet.com.com/4520-6033_16-4206967.html k...............................

People will eventually get tired of cell phones and the ripoffs from the celluar phone companies and go back to the good old days before cellphones of using a pay phone or politely asking "May I please use your phone to make a local call?" Or just telling people "I will be at [name of destination]. If you need me for something important, call me at [telephone number]. I'll be there from [time of arrival] to [time of departure]" Or, "this is [name of caller], at [location] calling. Is there anything to be picked up between here and [next destination]?" You now the way things used to work before cell phones came along. That way people won't have to put up with the discourtesy of a friend yakking on the phone during dinner at a restaurant. Or some twit using his cellphone and not paying attention while driving. Teenagers of course can bug Mom and Dad for a phone, but it will be one of those cream colored desk phones with a handset. Tied into the home phone number so that Mom or Dad can hear what Junior is talking about and to who. Of course the teenager will see the phone and ask: "What's that thing?" "It's called a telephone." "Does it take a picture?" "No". "Ring tones?" "You can beep off Mary Had a Little Lamb on it" "Email?" "You use your computer for that" "Call Waiting?" "Sure. Sit in the chair and wait for it to ring". Scanners of course will become so sophisticated that Dad can listen in on digital encrypted signals right out of the box, eliminating "Sam The Scannerman" and his basement brewed scanner modifications that the police know about, but Sam doesn't know the police know. |

I remember when I was his age, my friends and I would serenade one another with "Mary Had a Little Lamb" and other songs via the touch-tone buttons. We thought we were so clever. :-) The main thing that really irritates me about cell phones is this. When I'm on the highway and happen to glance over at an adjacent driver, I would conservatively estimate that 75% of the time, he/she is yakking on their cell phone when they are supposed to be driving. Just another way of taking people's attention off the road -- like we all need that. I cannot even think about paying what these cell service providers ask for their monthly plans without laughing. I still use public payphones on very rare occasions, but that is generally only if I am delayed and need to call someone to let them know I will be late. Nevertheless, I won't completely lambast cell phone usage for everyone. I suppose if you travel a lot or own your own business and you're out on the road a lot, they are a godsend. But I rarely use my home phone! I just can't justify the extra expense of a cell phone. Jackie |

: I use a DECT cordless phone which operates over the 1880 to 1900 Mhz band. The signal is easily blocked by trees and I can only imagine that at 5.8 Ghz it would be far worse. How practical are 5.8 Ghz phones? My 5.8 seems to work just fine under all conditions. |

hi Buzzygirl ........... I know what you mean , about people driving and yaking on their cellfones. makes me crazy too. something else tho ....... cellfones are kinda handy if you have a health emergency , accident or similar. anyone can buy an inexpensive cellfone from any garage sale for a couple of bucks and carry it in their car to use if there is an emergency. ( get it with the car cord for this use , so you won't have to worry about batteries ) you usually can't make ordinary calls on it ( tho there is an exception in some parts of the country where you can use a credit card on a roaming network setup ) but " every " cellfone is required to be usable for calling 911 in an emergency , even if it's not activated. so in other words .. " any " working cellfone can be used to make 911 calls if needed , at NO charge to the user. having one for yourself ( if you don't have regular cellular service ) and giving one to loved ones, that drive, is nice too. great for that emergency call to 911 if the need arises and inexpensive too. it's win - win deal ............ k......................

Yep, I know, good idea. My boyfriend just changed his cellphone service and has a cellphone that is no longer being used, so I might get that from him for that purpose. Jackie (Buzzygirl) |
