I used to drink the Koolaid, but in all fairness to Alvarion, there was
much more hope for a .16e future back then. Today, not so much. LTE has
already won and .16e will find only small, limited life and even less
mass development. Even if it had a long life, .16m won't do you a lick
of good in 3.65 GHz anymore than 16e will. These are subsets of
standards that have zero to do with the type of networks all are
building in 3.65 -- fixed. The FCC power and other rules simply do not
make anything but fixed technically feasible. And when things are not
technically feasible in scale, they will never be made to be
economically feasible. That means that no one will invest any truly
significant dollars to have end devices, interoperability and all that. 

3.65 with WiMAX is GREAT for fixed, but people need to wake up from the
misguided dream that any efforts on the mobile WiMAX front have
applicability to 3.65. Trust me, the last person in the world the big
companies in the WiMAX Forum (Intel, Huwaei, etc.) care about is a WISP
owner and they have zero interest in developing products for you. The
only possible exception might be Motorola, but their offer of a 3.65 GHz
product is less of an effort to support WISPs compared to finding a home
for their sunk investment in WiMAX because they will never re-coup it on
the carrier front -- that glossy dream has vanished. (Regardless of
their motives, it is a good -- if late -- move on their part in my
view.)

I understand your fervent hopes and dreams here, but what I am telling
you will save you much pain and wasted investment and cost if you can
accept it. Anyone trying to translate serious .16e/m/etc benefits to the
fixed/3.65 (beyond the slight range advantage of diversity, but at what
cost) world greatly misunderstands the space because every facet --
technical, social, political and economic -- work against you in this
debate. It is a fact, come to it sooner or later, but it is still a
fact.

....P.S. -- Alcatel dumped mobile WiMAX development many months ago and
the ranks of those dumping it continues to swell. Those who do not dump
it will find their lunch eaten by Huwaei, who is being subsidized below
cost by the Chinese government in a global strategic effort to capture a
major share of the global telecom market. Huwaei then (in my opinion)
uses its capture of .16e customers as the Trojan Horse to convert that
customer to LTE later.

Patrick,

16e is where the majority of the chipset development is at, and where
companies such as Alcatel/Cisco/Motorola/Alvarion/Zyxel are focusing,
and the new big deployments (Clearwire) are using 802.16e, and we want
the ability to go to 802.16m when available. We also want to take
advantage of the multipath enviroment utilizing mimo and wave 2
profiles. We have more hope of interoperability with 16e (Alvarion
states such things with it's open initiative) then we do with 16d,
although that isn't something we are counting on.

Patrick, I realize you used to work for Alvarion, and now Aperto but you
used to evangelize 802.16e and now you evangelize 802.16d, to us 802.16d
is going to be the lesser of the two technologies and offers little
advantage over our current wifi deployments, as we move to integrate
voice into our wireless deployments and replace some of our wireline
infrastructure and make a large investment in gear we want to be as
future proof as possible.
