Hi, I agree 100% the self contained radio 100% the best way forward, but the time lines and planning involved are huge investment in resources, needing all the networks working at the event. The boosters are way less power, much lower specifications and need that donor antenna to link to a base station, but they do work and a simple option for small events, that just need a little help to get the signal, not just ee usually everyone is effected as the event is either far from a tower or indoors where no signal can get into the building.
For us it's about having an office with access to make calls for emergencies that really helps. I know they are not the be all but they really help when your in the middle of "no where" and lost the signal a mile back on the way to get set up for a country show.
For small events I think they are helpful, suitable only for the indoor locations, find a few key areas you can put them and it can makes the difference between an event going well for the people paying to have there stand at the show, the visa cards working etc. and having that signal in an area where people know they can pick up calls and messages, even if its just at the canteen you put a booster it help the event. Anyhow just an idea and hope its helps
