Wireless device Frequency question. 1

[golyg]

I was looking into purchasing a cordless phone and a wireless router for my home office this past weekend but noticed that the phone and my wireless router would both use the same frequency, 2.4mHz.
I was curious if anyone knows if router technology may move up to 5.8mhz frequency or just always stay 2.4mHz....

I don't want to get the 5.8 phone and then see the routers and the other wireless gadgets move there as well.....

any ideas?

thanks

They are already there.
802.11a (hundreds of products available now) use the 5 ghz. spectrum.

Two thoughts:

. There are multiple channels within the definition. For example, at the 2.4 ghz. spectrum, see:

. The phone side is almost always DSS, (except for old 900 Mhz units). To be honest I have never had an issue, but I know some people have. Usually a channel change to the end of the spectrum on the router end will remove the problem: use channels 1 or 11. I would not place the base station for the phone next to the router, however. This discussion is typical of user experiences:

In all likeliehood you will end up with 802.11g on the computer side, which is the 2.4 ghz area. (802.11b and g have well over 90% of the market for routers). It is more likely, my experience only, that another router will cause interference before your phone will.

great links, thanks.

Interesting, it seems people may recommend 900mhz over the 2.4Ghz phones.

Thanks again,

Yes, the 900 mhz recommendation is popular. But honestly a good 2.4 DSS phone should work fine, just do not park the base station next to your router.

The 802.1x specs call for a seperation of 300' for shared spectrum devices. Honestly, with good phones and a good router they can co-exist without trauma.
