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