ISM 902-928.
Exact band and Power limit is relevant. Currently, the top 25% of ISM 900
bandwidth (channel 4) is unusable, in MANY areas, due to blead over from 930
Licensed high power gear (500W). If the same thing were to occur at the
lower portion of 900 ISM bandwdith, it could kill Channel 1 also, horribly
effecting WISPs using unlicenced. They also may be requesting to use higher
power on the actual ISM bands, argueing Public Safety is more important than
unlicensed use. Iftheir request is granted, specifics should be lsited on
how they are going to prevent interference with existing unlicensed band
users. Remember that the goal may not only be to use the spectrum. They
have benefit in killing off all the 900Mhz WISPs, that could compete with
Sprint/Nextel Next generation WiMax type Licensed 700M-900M solutions.

The preponderence of NexTel channels are in the private land mobile
806-821/850-865 conventional / trunking band, and a small percentage in
the 902-906 trunking band. So I believe whatever '900' channels they have
are *below* the 900 ISM band. I am most likely off on the numeric band
limits. But there are IIRC 15MHz of 25KHz channels that they hold licenses
among at 800 (and the separate reverse channels 45MHz higher), and only
4MHz of 12.5KHz channels at 900 (including both T&R, but I don't recall
the T/R split there).

Before everyone gets in an uproar about this, has anyone looked in to the
actual frequencies being used? I'm pretty sure Nextel has some licensed
900
MHz spectrum. I don't have time to dig around for the information but as
I
recall they do. I could be wrong. They certainly won't deploy an IDEN
system
in the unlicensed bands............Come on. They might however cause
interference with unlicensed stuff in certain situations where you might
be
co-located on the same sites. From what I have read I think this is only
going to be in selected East Coast cities anyway, and it's a band aid
approach to the rebanding process.
Thank You,

I am not familiar with the terms you describe below and I am a bit
confused. Can you break this down with a little more detail and
explanation? I would like to understand this as I think it is very
important for us to know what they are trying to do here in 900 MHz.
Thank you,

Nextel has been buying up 900 MHz trunked systems for years now.
Probably will do what they did to build their first ESMR (Nextel IDEN)-
Take perfectly good systems off the air so they can drive the users to an
unneeded tcchnology.

I think this is definately something we need the answer to (What part of
900Mhz). What exactly is "Green Space"?

They don't say exact freq's except for the reference to "unlicensed"...
