hi
das kam gerade ueber den atheros ticcer...

da bin ich ja mal gespannt wie sich das entwickelt

btw. hat schon jemand den monitor-mode-patch fuer den ipw3845 (intel) 
probiert und koennte mir sagen wie das geht?
ad-hoc laeuft, bis jetzt, super...

  Wi-Fi for Linux May Get Easier
By Eric Griffith

May 1, 2006

San Bruno, California-based Devicescape makes software you probably have 
used but don't know it ? it might be running some of your wireless 
hardware from big name vendors. The company is planning several new 
initiatives around what it calls "service-enabled devices," consumer or 
mobile products that wirelessly connect to the Web without the benefit 
of a PC.

"Imagine a wireless iPod with Wi-Fi on it," says Glenn Flinchbaugh, the 
company's Vice President of Marketing, "connecting directly to iTunes 
Music Store instead of synching with the PC." The vision is that devices 
using Devicescape software would automatically connect when in range, 
download what you want (be it data, sound, or video) and you'll be set.

To get there, the company is launching a technology it calls Easy Access 
to get past the setup hurdles faced by modern WLANs. All the Devicescape 
software in the future will include it ? and it's not proprietary ? it's 
based on the Wi-Fi Alliance's work on what it currently calls Simple 
Config, a one-button (or PIN-number based) setup of security settings 
similar to what is available in products today from Buffalo Technology.

"It's similar to Buffalo's AOSS and others, but it's multi-vendor and 
goes beyond what others have done," says Flinchbaugh. This technology 
will also be part of the wireless support in Windows Vista.

Devicescape is a Cisco partner, and builds Cisco Compatible Extensions 
(CCX) into its software. The company has had version 4.0, which has 
extra voice capabilities, available to customers since January.

So what about Linux?

Devicescape's Wi-Fi driver stack is going open source under the General 
Public License (GPL).  Called the Advanced Datapath Driver, it has been 
submitted for inclusion in the Linux 2.6 kernel. That could mean that in 
the very near future, instead of struggling to get drivers and cards to 
work together on a Linux computer, users may be able to plug in just 
about any card and get up and running. Developers could potentially stop 
porting drivers from Windows or writing new drivers from scratch.

"This is the first time Linux will have native Wi-Fi support," says 
Flinchbaugh. "Previously, it just had Ethernet. That meant it was always 
a hassle to support Wi-Fi adapters or chips on a Linux system, whether 
in a PC or embedded. We're trying to make it easy for the industry to 
make devices with Linux."

Acceptance of the Devicescape driver into Linux isn't 100 percent 
guaranteed, but Flinchbaugh thinks it's very likely. In fact, he claims 
that this contribution supersedes a previous attempt by Intel to get 
Wi-Fi support in the Linux kernel, though Centrino chipsets in laptops 
tend to be a bright spot in Linux support of Wi-Fi.

As for what cards or chips the Devicescape software will support 
immediately if it becomes an official part of future Linux builds, 
Flinchbaugh could only confirm that just about every Atheros Wi-Fi 
chipset would work out of the box.  Some chipmakers may need to write 
some low-level hardware-specific drivers.

The submission will also bring some multimedia Quality of Service 
technology to the Linux kernel.

"We found that previously the Linux kernel couldn't distinguish between 
streams of traffic -- say, one with voice, one with video and one with 
data," says Flinchbaugh. "That's important as people build voice and 
video into networks... we added that as well."

Rounding out a slew of announcements today, Devicescape also inked a 
deal with LVL7 Systems, which makes software for wireless switches. 
"They do switches, we do access points, so we said, ' why not form a 
partnership?'" Flinchbaugh says. Together, the two expect they'll be 
able to offer OEM and ODM vendors a complete WLAN switch suite of software.
