Good morning, Zeev. Regarding the wireless technologies used by the major providers, there is an ocean of such information out there, and the trick is to distill it to a comprehensible essence.
The essence of which I am aware is that AWE has assembled its network from the most disparate technological variety of systems of any of the majors and has chosen the most complex (expensive) upgrade path as well.
Extelcom is correct, with regard to the latter point, that Cingular has also chosen the same extensive upgrade path, but I think AWE still stands out as having the widest variety of pieces to integrate.
I realize this is little more than I previously posted. I also don't recall how AWE treats this matter on its 10-K - I will review that and get back to you with some details after the market closes.
regards,
