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
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.
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.
