At any rate, Warner has the card now. | There are only a few people that make 802.11{fh|ds|a} chips: | | 802.11-Frequency Hopping 2Mb/s | Raytheon, using their own MAC (chip is made by VLSI) and | discrete RF | Current(ish) cards from Webgear | | Oki, using the 7730 MAC and typically partnered with an old | Hewlett Packard RF chipset | Current(ish) cards from NDC Comms. InstantWave This seems like a very military-centric card. Do you know where one can get such cards? How far is the range and how well does it deal with, say, intentional EMF burns and 802.11 nodes moving at high speeds? If this is the case, I am pretty sure that I can get an "institution" to pay for the cost of developing a driver on FreeBSD. | 802.11-Direct Sequence 2Mb/s | Harris/Intersil, (Prism) using a variety of MACs e.g. AMD/Atmel | Many vendors using the already mentioned reference designs | | Lucent using the WaveLan chips (Hermes) | Many vendors using reference designs | | 802.11b-Direct Sequence 11Mb/s | Harris/Intersil, (Prism II) ditto above | | Lucent/Orinoco. ditto above | | 802.11a-OFDM 54Mb/s | Radidata and a couple of others have announced chipsets, but | this stuff is not in products yet. Will be v. nice. | Not many MACs announced yet. In other words, people who use these on their LAPtops may be sterile? | A few people have their own chipsets for their own products like Proxim. | | I can probably find out more from work - we've had a hand in some of the above. -- +------------------------------------------------------------------+ | keichii@peorth.iteration.net | keichii@bsdconspiracy.net | | http://peorth.iteration.net/~keichii | Yes, BSD is a conspiracy. | +------------------------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
