[lwip-users] RE: [lwip] Wireless Ethernet

To elaborate: The AT86RF211 is a transceiver and the AT86RF401 is a
transmitter only, neither of which are 802.11b compatible.

Thanks for the input Kieran...

The Atmel AVR chip you mentioned is a transmitter only and does not support
802.11b, I was thinking more along the lines of Wireless Ethernet (802.11b).

When I started with lwip I had not done embedded programming for years, had
never done anything with tcp/ip stacks, never used the Keil compiler, never
used a real-time embedded operating system and had never worked with
multiple threads, semaphores and mutexes on a low level. For people who
start like this the more documentation or references to documentation there
are the shorter the learning curve and the quicker the adoption of
lwip...the quicker the adoption of lwip the quicker we will have more
utilities/bug fixes for it...

Also, as far as developing a wireless Ethernet device/driver I was targeting
the people who are creating Ethernet devices/drivers, not the ones that are
not. I'm sure these people would agree that in most circumstances Wireless
Ethernet is better than Wired Ethernet, Wireless Ethernet is the future of
networking...

Anyway, thanks again for the input...

Vicente

Also, I forgot to mention...

If you're interested in developing some hardware to do this sort of thing
you might like to look at the Atmel AVR chips - they are an 8bit RISC
processor and have built in 2Mbps radio link, on chip memory etc.  I don't
remember all the technical stats off hand, but you'll be able to find out
more at www.atmel.com

TCP/IP already exists for these chips, and there's been some discussion in
comp.arch.embedded about this.  See

for example
