Cordless phone + extra base range?

[edro]

I see all these new cordless phones with the extra unit and base... and they are like 40 Gigawatthertz... but none of them give a range on the box.

I know the signal is determined by walls and interferance and all that... but at least give a decent estimate.

My parents want to have a cordless phone in their house, and also an extra hand unit out in the garage. It is probably 150ft, and through 3 walls. Do you think most of these $150 high end cordless phone systems would go through all that?

Any certain brands that are better than the other? I see that Uniden and Panasonic make some nice high-end models.

Thanks!

yeah def, we have some cheap phone we bought about 2 years ago that I can go otuside and across the street... thats thru a brick wall plus some drywall... and it still crystal clear

Cool... I guess I will get some for them then.

We have a Panasonic 2.4. For a school project we set the base unit on the porch railing. Made about 1/5 mile before it cut out. Not bad.

900mhz, goes the farthest

I have the Uniden TRU8865 5.8ghz phone and I can go all the way down my street with it and it's still crystal clear. My street is about 500ft-600ft.

What? So the 5.4ghz ones are just more clear?

The 5.8ghz phones are just as clear as 2.4ghz phones but they won't pick up interference from microwave ovens, and won't cause interference with wireless networks or security systems.

EDIT: got this off a site:
46-49 MHz - 40 to 250 feet
900 MHz - 75 to 400 feet
900 MHz w/spread spectrum - 200 to 1500 feet
2.4 GHz w/spread spectrum - 300 to 2000 feet

5.8 will have the longest range due to higher frequency. 2.4 may interfere with your and neighbors wireless lan.

I am replacing my 900 dss with another 900 digital phone. 900 is completely clear since everyone is on 2.4 and 5.8.

I think you got that backwards. THe lower the frequency, the higher the range. Look at 802.11a and 802.11b... 802.11a runs @ 5Ghz, 802.11b runs on 2.4ghz. The range of A is shorter though, but it has higher bandwidth.

See here:

This paragraph:
Of course the superior performance of 802.11a offers excellent support for bandwidth hungry applications, but the higher operating frequency equates to relatively shorter range. I've seen demonstrations of 802.11a radios delivering 54 Mbps with distances of about 60 feet, which is far less than the 300 feet or so that you'll have with 802.11b systems. As compared to 802.11b, you'll need a much larger number of 802.11a access points to cover a facility, especially large ones.
