Hello rr and Mike (from Florida) -- I have been enjoying your posts today.
There is no doubt that NN has some successful LMDS
and MMDS products -- But, after a rapid scan of their
"Leadership in Broadband Wireless Solutions" white paper and a brief review of their transceiver specifications,
I must question the wisdom of their apparent continued reliance on (obsolete) versions of modulation (EG QPSK), in those systems.

IMHO other systems which are now appearing on the scene,
using the varied versions of OFDM , will very soon make the
current NN systems obsolete -- primarily because of their
enhanced bandwidth, interference rejection characteristics, and potential for resolving the line-of-sight problem .
Then again, perhaps they are one of those forward thinking
companies who have joined the new OFDM Alliance.

The white paper (on page 4) BTW, refers to an Insight Research Corporation document "Fixed Wireless Options in
Telecom Networks 1999-2004".
While searching for this document, I just discovered a
very interesting "Index" which contains a link to that document. See gii.co.jp

And, Mike, sorry to see that you missed another fine New England
winter.

Best regards,
Mardy.
