[Ham-80211] 802.16e?

[Rich Osman]

Darryl,

Since the 802.16e standard isn't complete yet, it's hard to understand 
how equipment would be available anywhere.   There *are* high speed 
wireless data networks in Australia.  None I am aware of are OFDM. 

Unwired Australia uses Navini Networks (CDMA based)
Personal Broadband Australia (was CKW Wireless) uses Arraycomm's iBurst 
(they are owned by Arraycomm) iBurst is not OFDM.

Since both of these companies are in Sydney I suspect you are taling 
about one of them. 

IQ networks will be deploying UMTS-TDD (3G Time Division Duplex CDMA 
from IPWireless) in the north, but I'm pretty sure that's later this 
year.  This is the same technology already used by Whoosh wireless in 
New Zealand. 

You also said: "OFDM, so now power limits"  I'm guessing that this is a 
typo and was intended to say "no power limits."  If that is what you 
intended, there are still power limits imposed by local regulators 
regardless of modualtion scheme.


You are absolutely correct that wireless broadband data is rolling out 
everywhere.  It's likely that 802.16e will eventually dominate, but 
right now no one makes equipement. Some manufacturers claim the ability 
to upgrade with software.  We'll see.
