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. http://en.wikipedia.org/wiki/Huawei_E220 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. Max

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.

Hi -

why in hell do you want to use WIMAX? People are networking large areas all over the world (particularly developing countries) with WiFi + Batman or OLSR.

Of course *if* WiMAX becomes:

* Cheap * License-free * Supports Ad-Hoc networking

(which it isn't, nothing of this tiny list can be affirmed)

we can use BATMAN with it and maybe have a bit more fun than we already have with WiFi...

I'd rather ask the good fairy in my dreams for more WiFi drivers that actually support ad-hoc mode. Particularly USB. Ralink rt73 would be one of my favorites... Maybe the good fairy is already subscribed to this mailing list?

Dream on Elektra, dream on...

Hi well that sounds great. then we only need to research the additional IEEE and we need a hardware manufacturer, who is offering small FON like Routers, whith the batman protocol. So two users can connect to the internet over the air, while only one has DSL. To make it safe, encryption is important. Like this two one over power: http://www.devolo.com/co_EN_cs/produkte/dlan/dlanaudioextsk.html Isnt there a manufacturer, who can offer that with BATMAN inside?` That would be perfect, that I buy these two USB sticks, one in the laptop on a router with DSL, and the other on any machine in the air and this one can surf as well. maybe it is as well a stratey, to use BATMAN first from point to point (encrypted), and then to add the modus, that ANY Stick can be joined for DSL in the neighbourhood. For meshing there will be no hardware manufacturer, but for point to point like Devolo, this would be fine. The Software should be build in the stick like in the huawei USB modem, which simulates a CD rom. maybe we can start such a manufacturer contact?? Regards Max
