The PTP550 has two radios in it that you can bond together. The DSO ability hasn't been released in firmware. When the DSO is operational, it will only change one channel at a time so the link never goes down. You can also set the channel width separately for each radio. Another note is that these radios have not yet been approved for DFS frequencies, so that will be another firmware upgrade to enable that. About 5ms latency. Another feature in future firmware will be GPS sync from a CMM5. (Or Packetflux I'm sure)
