ZO,
Is such distribution among vendors tighten to availability of licenses or just simply business case?
Licenses are awarded or auctioned off at different Spectrums. The most valuable spectrum is between 24to 29 Ghz. Amount of bandwidth a carrier has is directlty related to the amount of spectrum. For example, Maxlink in Canada owns the right to use 1 Ghz of traffic from 27.35 Ghz to 28.35. Wispra, in contrast, has 400 Mhz of spectrum at 24 Ghz. Maxlink has 2.5 times more bandwidth capabilities than Wispra, for example.
My understanding is that at 28 GHz, the LMDS band, carriers have more than 1 GHz to work with and Qos is higher and you can cover higher population.then for example at 24, but not 38
Your right. At 38 Ghz, the signal cannot sustain itself for 4-5 miles, like it can at lower frequencies of 24 or 28 Ghz.
Any idea why WinStar is pushing 38 where Nextlink 28 (Nexlinki conservatism?
Nexlink paid over a billion dollars for their 28 ghz licenses. There can only be one 28 Ghz carrier in any given market.
Hope this helps a little. It's a much more sophisticated than this, but I think you get the general idea.
Cheers,
