Your assessment is indeed correct, if you increase the beamwidth too much you do indeed lose bandwidth capability, the trick is to have sufficient power to be able to supply the bandwidth desired over the range required. Our system uses the wide beamwidth technique for the SONAbeam155-2 (2km product), which is a fixed point-point system. We tighten the beamwidth and implement a dynamic tracking system for the longer distance unit, the SONAbeam155-4 (4km product) as well as the higher bandwidth systems, the SONAbeam622 (622 Mbps) and SONAbeam1G (1.25 Gbps). I do not consider the use of the wide beamwidth approach to be self-defeating however, as it does allow for a lower cost solution given the removal of the cost of extra mechanics and logics to drive the dynamic tracking system otherwise required. This simply helps to make the technology an affordable option for more implementations. I hope this helps. Sincerely, Leigh McBain Director, Product Sales/Support fSONA Communications Corporation
