This will allow me to talk to a whole lot of people at the same time. The next question I had was, can I use a whole lot of these at once? It looks like I can. Metafilter provided the answer.
Can two separate 5.8GHz cordless phones co-exist in a home?
I've got a Uniden 5.8GHz cordless phone set that I use for business on a VoIP line and I want to get another cordless set (with digital answering machine) for my home land line.
Because I have an 802.11b/g network I don't want it to be 2.4GHz (or 900MHz) so the second phone set would also be 5.8GHz (probably the AT&T 5840).
And the answers ...
Uniden's phones are frequency-hopping spread-spectrum, and two different systems should automatically stay out of each other's way. A FHSS phone 2.4 GHz phone will also stay out of the way of a WiFi network -- I use a Panasonic 2.4 GHz phone and it works fine with my WiFi. But I'm looking to upgrade to a 5.8 GHz system eventually anyway, because that's where all the cool new features are coming out.
Being pedantic, no they don't. They stay out of each other's way by pure chance by constantly changing frequencies at random. They do occasionally collide, but only for a fraction of a second until they next hop to new frequencies.
Lovely!
