it really depends on the type of operation and measurement you are gonna do but you must "engineer" a way not to TX regulated traffic anyway . a shield room is your first choice , engineering the patch antenna on the handset would be another , of course you always can ask your regulatory for temporary limited license to do research and the cost depends on how crowded your area is .

most of the test systems are not built to be used for on-air operations . the ones that offer such features must be used in Shield rooms where no signal gets in or out . these rooms are expensive but usually tech universities have some rental hours for their shield and antenna rooms . its expensive as well , otherwise you are probably going to have some conflict with local regulatory sooner or later regards
So how does it work "off-air"? I'll need a shielded cable and attach it on to the antenna pads of the handset?
The last thing I want is regulatory hassles.
