I wouldn't think you would be required to use FDD. 802.16e supports
varying channel widths, so you could for example deploy a multi-point
system with two 10Mhz channels or six 3Mhz channels all TDD.

Thank you.
What are you doing about equipment to operate in that spectrum range?
That is the $100,000 question right now. 802.16e for mobility and
fixed wireless is designed strictly for TDD use. I have paired
frequencies which are generally relegated to some type of FDD system
like those used in the cellular industry. There are some next gen
choices in that area that I am looking at. I personally believe
someone will adapt 802.16e to work in FDD whether it is standards
compliant or not. Then I will likely choose that. I could use 802.16d
gear like BreezeMax but I really want to offer mobility as well as
fixed which is not an option with 802.16d. Nortel is working on me
pretty hard right now. We'll see where this goes. It is going to be a
while before I can get the incumbent users of my bands relocated so I
have some time to ponder.
