We have used the 2.4GHz version of the Exalt radio - the EX-2.4i. We were fairly happy with it. The latency and jitter was great for a TDD radio, better than any I have seen. It was very reliable from a data-forwarding perspective. The management interface was nice when it worked, but the HTTP interface would lock up after extended periods of operation. We also got unusable values from some of the SNMP error/discard counters.
In the end we took it out due to the need for more bandwidth and some issues with intermittent interference (to be expected in 2.4GHz). If the specs meet your needs then it would probably be a good solution.
