Transmission Band1.9 GHz? what does that mean when it comes to phones for examplez
American Telecom 1.9 GHz and is $36.00 a good price for this type of phone. im trying to buy a house phone that is cheap that is why im asking.

Answer
1.9Ghz is the RF that the handset and base communicate with each other.. that is the frequency that DECT phones operate on... it will provide better range compared to 2.4 and 5.8Ghz phones..

with radio waves the LOWER the frequency the FURTHER the range...

also, since DECT/1.9Ghz has been set aside for cordless communications there is no other consumer wireless devices in this frequency range such as in the 2.4Ghz range, where there is wifi, wireless video cameras, baby monitors, microwave ovens and other devices...

Is there a good landline phone, with LOUD volume & LOUD speakerphone, that works with Hearing Aids?

Dubber

I've heard there are telephones out there for the hearing impaired but what I am looking for is a land line telephone for my parents who wear hearing aids but refuse to wear them when using the phone. Both say they get ringing and feedback when using a cordless phone while wearing hearing aids, but when they remove them the volume of the phone isn't sufficient.

So...I am looking for a land line base phone, with speaker phone, and better than average volume and sound clarity. If possible, the phone system would come with one or more cordless phones, also with exceptional volume and sound clarity. Oh, I should also mention that they, and I, are very limited financially so can't spend a lot on this.

If a phone with these features doesn't exist, is there some sort of device that can be attached to the phone to increase volume and sound clarity?

Somewhat related, can anyone define a few things for me:

What is the difference between a 5.8 GHz, DEC 6.0, 9 GHz, and some other numbers and acronyms I can't recall atm.

Thank you for your help!

Answer
there are plenty of hearing aid compatible telephones http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832047&No=0&Nr=12001&Ns=&Ntk=MainSearch&URL=vShopSearch&cmTag=true&catalogId=13401&storeId=15001&Ntt=hearing+aid+compatible&cm_sp=SiteSearch-_-MainSearch-_-Consumer

DECT - Digital Enhanced Cordless Telecommunications these phones operate in the 1.9Ghz frequency range - an unlicensed spectrum that the FCC has set aside strictly for cordless telephones.. this is the latest and greatest in cordless phone technology...

5.8Ghz operates in this unlicensed spectrum, there are some other consumer wireless devices that operate in this spectrum, but it is one of the least crowded frequencies - however since it is the highest frequency cordless phone on the market, it also has the least range from handset to base (some 5.8 cordless phones also operate on the 2.4 Ghz spectrum)

2.4 Ghz operates on this unlicenced spectrum with many other consumer wireless devices such as WiFi routers, microwave ovens, wireless video cameras, etc...

900 Mhz phones operate on a crowded unlicensed frequency with many other consumer wireless devices, such as baby monitors, wireless speakers, garage door openers, car alarms, etc... also unless the phone has DSS then it is insecure and can be monitored by a radio scanner... (DECT, 2.4 and 5.8Ghz phones all have some form of DSS, or FHSS)

DSS - Digital Spread Spectrum - a form of encryption to prevent eavesdropping...

FHSS - Frequency Hopping Spread Spectrum - a form of encryption that also continuously searches for the best channel, and keeps changing to the best channel between the handset and base (normally these phones will not have a channel button, because the phone is constantly changing channels on its own)
