How well do those work? What kind of range are you looking at, and how
many users can use that added range at once? My friend gets REALLY
weak signal in his house (0 bars to roaming), yet outside by the road
he will get half to 3/4 signal... if those are not TOO high priced
would it be smart for him to buy one and hide it in a shed outside
near the house or something?

Repeaters work as long as they are setup correctly.

Above sites have more brands to choose from in addition to the original
post.

I have one from 4 years ago and if I unplug it, I have no signal in the
house to having 5 bars.
The Antennas ( both ), cable and amplifier make all the difference. The
system as a whole has to be installed correctly.
It fairly simply, just has to be done right.

Anyway, check out links. They have more info about how the things work. :-)

Hope this helps.

I'm waiting for a snide rejoinder on this one from Scott.

and since this know-it-all knows nothing about repeaters....

Illegal to install in US unless you have carrier's approval, confirmed by
FCC staff.

Yeah, and your little generality showed you're the expert, right?

NOTHING works right if you don't set it up correctly.

Tell it to the Sprint folks that have been promoting it.
They think since all the stores have one you should too.

Who's been promoting it? I see no reference to that. Are you promoting
illegal activity?

Do you know how the repeaters reconcile w/ CDMA's open-loop &
closed-loop power control systems?

While both GSM & IS-136 have subsequently implemented power control
procedures for improved capacity via tighter re-use, the FDMA air
interfaces are still far more tolerant of imprecise power control.
CDMA, on the other hand, lives or dies by the sword of power control,
as in CDMA power essentially equates to bandwidth.

W/ what appears to be a minimum 40 dB of gain produced by the active
repeaters, such could be just what is needed to salvage a marginal
signal. But amplification of an already reasonably strong CDMA signal
could wreak havoc w/ power control, particularly on the reverse-link,
w/ the mobile(s) being amplified by the repeater transmitting at their
minimum power floor, unable to decrease Tx power any further in
response to commands from the BTS, thus decreasing the overall
capacity of the cell site.

The amp I have keeps attenuated beyond a certain level.

http://www.canyonriver.com/accessory_rfbooster.html
It's the JAA-001

Yep it's older then dirt but, could get barely get the pilot before ( CDMA )
and barely get AMPS SAT.
Now, I get 5 bars on my Startac 7868 ( CDMA ) and when I am in analog mode,
get 4 bars and a great signal.
I ran a 1/2" Foam Heliax ( brand ) cable up to the roof, put a spark
arrestor inline, and used a Planar Antenna outside and a 3dB magnet mount
ant inside and did a little pointing and viola!
Much better reception. I haven't seen any issues with power control.
The repeater has some sort of limited built in power control to keep it at
..6 up and .1 down, from what the manual that came with it said.

I know my battery life greatly improved after it went in.

Anyway, the new repeaters have to be better nowadays, being that the one I
have is over 5 years old. :-)

Well, Phillie, did you by any chance actually *read* what you quoted?=20
"unless you have carrier's approval." If SPCS is providing these=20
repeaters, don't you think it's safe to say SPCS is also providing=20
the permission to do so?

Fine, but its another SECRET, to trick folks into thinking SprintPCS
has acceoptable indoor coverage when the 1900 MHz band is known for poor
building penetration.

I'd call it a clear case of a Deceptive Sales Practice.

And "everyone else does it", does not change the deception.

It's fallacious that 1900 MHz has poor building penetration. Its
subject to the same vagaries as all other RF. The higher the
frequency, the more attenuation in free space. Building materials will
affect various frequencies in different ways. There are some buildings
that high powered FM transmitters can't penetrate.

>I'd call it a clear case of a Deceptive Sales Practice.

If a company claims coverage in a building and they deliver, do you
care how they got it there?

>And "everyone else does it", does not change the deception.

If they deliver what they promise, whoever it is, it is not deception.

We've got people here who claim that 800 MHz carriers can't deliver
service to them when the 1900 MHz carriers can. It's simply the
placement and number of transmitters.

If the mobile (amplified or not) doesn't obey the power control
commands of the cell, the mobile will be commanded to shut down.
