For GSM outdoor we're using FSR - frequency shifting repeater

Br,

If you have MetroEthernetNetwork, I can recommend you ipaccess (nano/femto/picocell). I think a repeater isn't panacea, because it doesn't expand capacity.
For eample http://www.ipaccess.com/picocells/nanoGSM.php

No, we don't have MetroEthernetNetwork yet.

Thanks for suggestion

For outdoor repeaters ... with no condition to be extra-small in size ...
Freq. shifted repeaters of andrew now ... old name was Mikom.
Freq. translated repeaters of avitec ... old url was www.avitec.se ,
now under name axell wireless ... excellent one.
All repeaters are with its OMCs which makes remote polling / control and command settings much easier.
Google for the details or ask forum more detailed ...

Intermodulation Cancelation System (ICS) Repeater is always the best one.

You can have 3 sectors configuration with a very minimum distance between donor and services antennas while we can't have this with RF or Frequency Shift Repeaters

How many units do you need?
I can offer you best price and discount for ordering more than 50 units :)

PM me !!

@elhape
could you attach some tech. description of products you mention ?
seems interesting this small distance between pickup and serving antenna ...
as this two antenna isolation in this cases is always an limiting issue ...

Axell Wireless is actually a merger between two companies: Avitec and AFL, and later on they purchased Dekolink Wireless from Israel.
I've been working with both Avitec and Dekolink repeaters, although we used Avitec for donor/repeater configuration, for large rural coverage, and Dekolink for medium-sized indoor coverage. And we also used Avitec for FiberDAS fiber-fed indoor multi repeater system.
Both of the repeaters are very good, although very expensive as well. Maybe Dekolink isn't that expensive when you compare it against it's output power.
Just wanna mention that Avitec repeaters had a problem with poor weather protection of it's casing, causing LIMPA modules to fail if there's high humidity, so take care about that.
For indoor solutions I'd say that Andrew repeaters are just as good, and they are much cheaper.
Still, for large area coverage, I'd say it's better to go with microbase station, than with repeater.

Could somebody please shed some light on Intermodulation Cancelation System (ICS) Repeater and Frequency Shift Repeaters? What are the differences and what is the margin of gain they can provide and other concerns?

you can have channel selective and frequency shift but there is some difference between them .
1- isolation in frequency shift can easily be achieved because using different frequency but in channel selective you have harder obtain and this case you have vertical isolation or horizontal isolation recommended is vertical .
2- higher gain in channel selective than frequency shift.

If I may add,,, FSR has limited channel only compared to band selective ( i think 2 channel only is available in market).. anyone who had tried using a proven vendor outdoor repeater in their network ,, please enlist.. thanks all!
