erm, a 108Mbps radio will not give you 90Mbps of video, that is rubbish. maybe 40Mbps at a push with a very good link.
i think this is about right on the old 54/108 technology thats got to be 8 or 9 years old now. I wouldn't want a car that old....
the 11n is 150mbps on a single antenna and 300 on a dual antenna, latest technology, we get 95mbps test on either.
we are quoting in an 11n max at 25km so i will let you know how that gets on. the silvernet guys are very confident and said they have an 11n link in at 33km.
as for sales gimmicks, all you wireless companies are the same you all want USP's. But i think that the silvernet stuff just works, also putting an indoor 11n router into an outdoor box isn't very good either, ahem net***r etc... probably what you have used for your short high bandwidth hops.
you should have a look at the silvernet 11n stuff it is brilliant if you havent already. Designed for outdoor use.

Their 11n max says it does up to 60KM
this is a micro link up to 2km
