Cordless Phone-s often fail to work in NYC apartments with thick heavy walls.

• and don't get me started on the Baby Monitor market

The 5.8GHz Uniden I just bought won't even work 1 room away.

I'm hoping that a digital technology will improve things.

• you have to be careful, because some phones have "digital" in the name, but they're talking about the answering machine feature, not the phone radio.

Some different digital technologies are [Spread Spectrum] ([DSS]) and [Frequency Hopping Spread Spectrum] ([FHSS]) and [Direct Sequence Spread Spectrum] ([DSSS]).

• It sounds like [FHSS] will interfere with [DSS]. And that having multiple [FHSS] sources is a bad idea. And that multiple [DSSS] sources is a bad idea.

• This (and this ) makes it sound like [FHSS] is simply better than [DSS].

Jan'2006 - bought the Panasonic [KX]-[TG5431] (5.8GHz/[FHSS]) - seems great, good sound quality throughout the apartment. Cost $90 and included an answering machine, so I could give away my old one and free up some counter space. (Product Review)

Feb'2007 - Wired Mag reviews some 5.8GHz phones. They demand multi-handset support (which might become necessary if I switch over to VoIP and dump my POTS service). They don't discuss [DSS] vs [FHSS], etc. They like the [ATAndT] phone.
