Germany Finds Kismet, Custom Code In Google Car
theodp writes "While waiting for a hard disk of Wi-Fi data that Google says its Street View cars gathered by mistake, the Hamburg Information Commissioner's office performed tests on a Google Street View car in a controlled environment with simulated wireless networks and issued the following statement: 'For the Wi-Fi coverage in the Street View cars, both the free software Kismet, and a Google-specific program were used. The Google-specific program components are available only in machine-readable binary code, which makes it impossible to analyze the internal processing.' Interestingly, a 2008 academic paper — Drive-by Localization of Roadside WiFi Networks (PDF) — describes a similar setup, and its authors discuss how they 'modified Kismet, a popular wireless packet sniffer, to optionally capture all packets received on the raw virtual interface.' Computerworld reports that lawyers in a class-action suit have amended their complaint to link a Google patent app to Street View data sniffing." -
Linksys WRT54G drops Linux
avorobiev writes "WiFi Planet is running a story on all the advantages of Linux-based firmware for the Linksys WRT54G router. Little do they know that as of v.5 of the router Linksys dropped Linux and switched to VxWorks. And yes, they crippled the hardware (halved the RAM) so that third-party firmware can not be installed anymore." -
U.S. Firms Take on Australia's CSIRO Over Patents
dingram17 writes "ABC News is reporting that six U.S. computer companies (Apple, Dell, Hewlett Packard, Intel, Microsoft and Netgear) are taking legal action to try to break a U.S. patent that the CSIRO holds on wireless networking. The CSIRO has patents on OFDM technology, as used in 802.11a and 802.11g. It has been alleged that the CSIRO demands $4 per chipset for the use of this technology. It appears that the patent in question is U.S. Patent 5,487,069 'Wireless LAN.' From a quick look, this appears to be a wide ranging patent." -
Cutting Through a Wi-Fi Traffic Jam?
eric3xxx asks: "A week or so after Christmas, I tried to connect to my home wireless network and while I could see my access point I could not connect. After scanning the network, it turned out that there were at least twenty new access points in my apartment building (and in the surrounding buildings). Most of them had names such as 'linksys' and were all set on their respective vendors default channel (apparently a lot of people received 802.11b/g WAPs as presents). I tried changing the channel on my access point, starting at 1 and continuing through all of the channels, and none of them worked (probably since the channels overlap). In any case, I have no clear solution to this problem. I suppose I could boost the signal, however, that also increases noise. Perhaps I could convince my neighbors to put together a shared wireless network. I may just switch to 802.11a since it isn't as widely used." Has anyone else had success in configuring their APs to work in an areas of heavy wireless traffic? -
Voice Over Wireless LAN On A Chip
prostoalex writes "Texas Instruments produced a single chip platform for transmitting voice over wireless LANs. The company says the phones using the chip will be available by year-end. The chip supports 802.11b and 802.11g wireless networks." -
Cisco Sued over OFDM Wireless Standards
Agent Green writes "It's definitely not the first time someone has been sued over a standard, but Wi-LAN is in the process of taking Cisco to court over the OFDM encoding which it claims to have patents for - the standards in question apply to 802.11a/g. Interestingly, this case is being brought in Canada, where the defense needs to prove its case. Might be time to join and expand the patent busting brigade?" -
Open Source Hotspots
darthcamaro writes "Not that long ago it was a serious pain to get an 802.11b card to work on a Linux machine. [ed note: We love you Jean Tourrilhes!] Wi-Fi Planet has a story where they do an overview of a wad of open source Wi-Fi projects. Did you realize that you don't even need to spend the dough for an Access Point? - standard Linux routing is enough to create your own access point, with a few other tools like Public IP's Zone CD or the Less Networks Hotspot server, you can freely create a hotspot and manage it all in minutes. I guess all this means that both Wi-Fi and open source are literally 'everywhere'."
