On the Cisco note Matt, Cisco is making ASN gateways for WiMAX and so far the only ones they have slide into our WiMAX macro base stations, so we have and are doing considerable work with them to integrate some of their pieces into ours.
Regarding 3.65 MHz, in spite of the ruling's imperfections, I think it presents a great opportunity. It certainly will be much cleaner spectrum than we are all used to and it gives the WISP market its best and first real opportunity to implement business models with limited truck rolls, at least relatively close in to the base stations. And if Intel eventually turns on the ability to use the band within its chipsets then the opportunity gets even more attractive. But along with that point, the only way operators will be able to participate in that part is if they go with an 802.16e version of 3.65 GHz product. The first WiMAX products to hit the band will be based on the old 802.16d standard. While that will provide some of the service benefits of WiMAX, it will not have all the goodies 802.16e will have nor should it be able to achieve the same link budgets that can be achieved with 802.16e. On the regulatory side, vendors also have to solve the unrestricted contention requirement or else your gear will be relegated only to the lower 25 MHz. I suspect some will try to come out with proprietary means of dealing with this, but with that goes some of the standardization. That's what 802.16h set out to fix when the task group was formed 2.5 years ago and it is what we support. Another set of hurdles are the exclusion zones. These zones are 80 miles in radius -- that's over 20,000 square miles per license. The FCC does not require the satcom license holders to work with you and you can't deploy along much of the eastern and western seaboard without their approval. And should they agree to work with you, the FCC does not tell them how to do so, so they can require anything of you they wish pretty much, and that might make such areas too onerous to deploy. In the mass of the interior though you won't have to deal with this since there are no zones except near Louisiana and Dallas, Texas. In any event, it is likely that WISPs will have several choices for this band beginning as soon as later this quarter. The decisions you'll need to make: exactly what type of business model do you want; do you only want to stay in the lower 25 MHz; what mix of self-install install and outdoor units will make the model work for these higher cost WiMAX base stations; do you want to be able to support laptops in the network; what model makes your network the most valuable; what is your planned exit strategy? If you only want pure fixed, maybe the old 802.16d versions you are about to see will suffice. If you want more, you might want to wait a quarter more or so for 802.16e versions to appear.

Now that we have read your post regarding Alvarion's market leading position and your insight into the entire market, I'd like to know your thoughts on using WiMAX in 5Ghz and 3.65Ghz. It is fair to say that most readers of this list won't be gaining access to the ideal spectrum profiles for WiMAX. That leaves 5Ghz and 3.65Ghz. WiMAX vendors are offering or planning on offering WiMAX like equipment for these spectrum ranges. As a side note, I'd also like you to comment on plans to integrate WiMAX base stations into the network better than they are today. For example, why not produce a 7600 line card for your base station? Or do we have to wait for Cisco to complete their WiMAX acquisition for that? -Matt ------------------------------------------------------------------------ -------- ** Join us at the WISPA Reception at 6:30 PM on October the 16th 2007 at ISPCON ** ** ISPCON Fall 2007 - October 16-18 - San Jose, CA www.ispcon.com ** ** THE INTERNET INDUSTRY EVENT ** ** FREE Exhibits and Events Pass available until August 31 ** ** Use Customer Code WSEMF7 when you register online at http://www.ispcon.com/register.php ** ------------------------------------------------------------------------ -------- WISPA Wants You!
