39 .Nd "Aironet Communications 4500/4800 wireless network adapter driver"
42 .Cd "device an0 at isa? port 0x140 irq 5"
46 driver provides support for Aironet Communications 4500 and 4800
47 wireless network adapters.
48 This includes the ISA, PCI and PCMCIA
50 The 4500 series adapters operate at 1 and 2Mbps while
51 the 4800 series can operate at 1, 2, 5.5 and 11Mbps.
53 and PCMCIA devices are all based on the same core PCMCIA modules
54 and all have the same programming interface, however unlike the
55 Lucent WaveLAN/IEEE cards, the ISA and PCI cards appear to the
56 host as normal ISA and PCI devices and do not require any PCCARD
59 The PCMCIA Aironet cards require kernel pccard driver support.
60 ISA cards can either be configured to use ISA Plug and Play
61 or to use a particular I/O address and IRQ
62 by properly setting the DIP switches on the board.
64 switch setting is for plug and play.)
67 driver has Plug and Play support and will work in either configuration,
68 however when using a hard-wired I/O address and IRQ, the driver
69 configuration and the NIC's switch settings must agree.
71 require no switch settings of any kind and will be automatically
74 All host/device interaction with the Aironet cards is via programmed I/O.
75 The Aironet devices support 802.11 and 802.3 frames, power management,
76 BSS (infrastructure) and IBSS (ad-hoc) operation modes.
79 driver encapsulates all IP and ARP traffic as 802.11 frames, however
80 it can receive either 802.11 or 802.3 frames.
82 selectable between 1Mbps, 2Mbps, 5.5Mbps, 11Mbps or
83 "auto" (the NIC automatically chooses the best speed).
87 driver configures the Aironet card for infrastructure operation.
