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.

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.
