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.
Can you expand on that? The Cisco platforms we are running for our
network support the ASN gateway. I'd like to understand what advantages
this setup has as opposed to just using Ethernet to connect a base
station to my Cisco.
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.
What goodies are you referring to with e? Based on the results of our
testing with 3.65 we don't think mobility is going to make much sense in
the band. Further, it doesn't appear indoor (self-install) SMs are going
to do well beyond 1 mile from the base station. All of which is fine
with us. We just want the spectral efficiency and the additional
spectrum. 802.16d gets us that I believe.
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.
That would be an interesting development. I suspect we will see
802.11n-based gear available for the band soon as it should be able to
operate in the entire 50Mhz.
