Hi -
you'd be surprised. I have built WiFi links up to 25 km (480 KByte/sec
TCP throughput with 802.11b). Which is not rocket science and actually
relatively short, compared to the WiFi world record of 380 km...
Even with the default antennas, a popular Wifi router has a range of
approx 2 km at 1 Megabit, given a clear fresnel zone.
What you are referring to is the fact, that those WIMAX modems don't
support multipoint-to-multipoint networking. Actually there is an idea
to have this mode in WIMAX (don't know the IEEE draft number, though),
but it surely is not implemented...

Hi thanks for the feedback
CB Funk is only up to 9000 baud, that is too slow.
The question is, if every laptop has a HDSPA WIMAX stick, if those can
connect directly to each other, so, that they can exchange data,
the answer is now, as both need a SIM card, but then the question is,
if any firmeware can be coded, that the Stick can send to each other,
as they have the capability to send to 3-7 km or so.

Can two E220 connect to each other without a sim card with a new firmware?
I guess that is not possible, and that will limit BATMAN to wifi chips
of a range of a few meters. not kilometers.
Given that, i see only one solution, to build Batman based on the
Wimax/HDSPA and E220, which then will cause Data retention logging as
there is an ISP, but you can solve this with encryption layer networks
(http://www.i2p2.de/ / retroshare.sf.net <http://retroshare.sf.net>
etc). But that is nonsense as well, as you use batman, where no cable
or central wimax station is given.
So batman will stay on wifi, if there is no hardware development on
wimax, that these chips can mesh together over greater distance
without any sim-card.

Hi -
I'd say if you run a data network you can run BATMAN on it. For
packet radio you may want to choose a Originator interval in the
range of 30 seconds or more, though.
