hi w_w,
thank you sincerely for your speedy, generous and thorough reply.
i thought i read that VOFDM was a virtual mobile wireless technology, that it overcame (or could overcome, with further development)line-of-sight limitations, so that if i, the user, can roam among the skyscrapers, i would not care that the antennae of the senders are fixed. i realize that the ultimate solution has to be mobile wireless
sender/receiver can roam. you mention the traditional providers, using CDMA, enhanced TDMA etc. since the superior among them is CDMA, whose payload is limited, i find myself back to square one in trying to dope out who has at least an edge in achieving the next step.
on a slightly different angle, do i have it right that for LMDS, teligent is the current leader? is there a website - other than teligent's - to read about LMDS? Dr. Levy says LMDS is needed for true broadband access. that seems to me an enormous advantage, and that rather than seeking low-cost repeaters for VOFDM, as cisco is doing, it would be more worthwhile for someone to develop repeaters for LMDS, and to increase LMDS's broader applicability. |
