> Is anyone familiar with 3G repeater gear? I'm asking for a neighbor whose family owns a cottage in a Swiss mountain valley with poor 3G reception.
well its not so easy to give you an definite advise, the signal is based
on reflection i believe, that has to be resolved.
you have to take into consideration is there a point with clear view
for the next tower ?
reception based on non sight will not give any satisfaction.
3g has even more bandwith need which degrade the signal more in case of
non sight.
there are a lot of 3g enabled repeater (basically 2 way amplifier)
available from chinese dealer.
price will be 200-300$ and deliver arround 60db gain up to 28dbm
forgett about the cheap office repeater, those are only usable inside
office in a small range and have tendency to oscillate which will call
BAKOM on the Plan.
And you need antennas at a high pole .. for 60db you need at least 15m
between the both antennas, good cable (rg213 or better cellwave above
3/8" the antenna on top vertical yagi 16-20element.. and below
horizontal panel or even yagi.
due the different polarisation of the two antennas you win theoreticaly
20db more decoupling (real you will reach 16db)
the antenna for the user could be up to 600m far away if used an high
gain antenna.
if an higher amplification needed you need an channelselective repeater,
those are available up to 90db
but they need to be tuned onsite on the specific channel and of corse
need better cable to prevent feedback between in and out.
channelselective repeater with 90db will cost up to 2000$. 5/8 cellwave
will cost aprox 8-10$ per meter.
and dont forgett the N-Plugs for those cable .. 12-15.- each
i got only a usable system with 5/8 cellwave with up and downlink 25m
seperated and the user antenna was below of a metal roof, the
decoupling between the two antennas was 70db
if you only need data would an 3g modem mounted near the antena with
good reception and an wlan link the better idea, more stabil more
reliable and will not reach your 1000.- limit
an 3g modem doesnt cost much, and two ubiquity nano loco on 5.8ghz for
300.- will bridge 1-4km on sight if need more distance use airgrid 5m
for the same price, they will go up to 8km.
i hope i could help a bit to give you at least an idea
