I was wondering if there is a manufacturer which offers qualified GSM (2G/3G) communicational equipment for lower and slower flying aircrafts and mainly helicopters?
Basically a GSM transceiver is what I am interested in ((external) antenna and communicational unit on board) for voice/data directly over a cellular network?

I hope it wouldn't be using it for a com link, as GSM makes very annoying sounds for the user when you are on the fringe of reception and your signal is cutting in and out...I'd rather deal with static from AM modulation (like we currently do!).

Get a signal amplifier inside connected to the GSM device inside, and an antenna outside... there are several antennas that work in L-band that can be used as GSM antenna too... and some transponder antenna. This is used in some aircraft to transmit data through a 3G cellular network once on the ground. Voice would be disabled I would think.
The question now is, what kind of data do you want to receive/transmit? Volume? filesizes? Why not satcom like Iridium SBD or SwiftBroadband? Equipment cost issues? Airtime cost issues?
The thing with 3G systems for use while on air over cellular networks... would anyone want to STC the stuff if you custom make them?

That's the point... not willing to custom make them because of certification issues. Looking for partial or complete OTS solution - which could mean - qualified antenna and qualified transceiver (voice/data) or qualified system.
SAT-COM is too slow for transmission of larger data... at least until Iridium NEXT hits.
The idea is to use 3G (where available) for data transmission (both up and down). I am aware of the challenges of GSM/UMTS handover, but it still works fairly good under the same conditions now when you "accidentally" leave your mobile phone on
Can't believe there isn't a solution already on the market. Must be.

Get a swiftbroadband high gain antenna like Cobham's HGA6500...
Streaming video from surveillance has been done using SB before...
Or get the SB system on this: http://www.scottygroup.com/scotty_diamond_da42mpp
Yes it's only up to 432kbps... but GSM in airplanes won't be much above 2G/EDGE speeds with external antennas while flying around...
And a Ku/Ka band satcom solution would be too big for the aircraft in question?

I am aware of the alternative solutions, which have disadvantages on their end.... but I would still like to know if there is an OTS product for data/voice communication over GSM/UMTS....!?

Not as far as I know.
There are some guys in the US doing this kind of installation for experimental aircraft...
As of for commercial use, no. The nearest you can go to it is the FOQA 3G data transmitter that sends FOQA and some QAR data over 3G... as soon as the aircraft is on the ground.
People who needs 3G connection without airborne certified datalink just slap a patch antenna on a window and connect it to their 3G modem...
