We have a customer who wants a wireless bridge/mesh link between two buildings. They want as much throughput as possible, better than 802.11b/g 54Mb for preference. We've identified Cisoc 1552E or I APs as suitable devices but we can't tell from the literature what sort of bandwidth we can expect over the backhaul link, will it use 802.11n speeds or are we stuck with b/g data rates? Any advice would be much appreciated.
