.Sh NAME
.Nm ray
.Nd Raytheon Raylink / WebGear Aviator IEEE 802.11 2Mbps Wireless
.Sh SYNOPSIS
.Cd "ray* at pcmcia? function ?"
.Cd "options RAY_PID_COUNTRY_CODE_DEFAULT=RAY_PID_COUNTRY_CODE_USA"
.Sh DESCRIPTION
The
.Nm
device driver supports the Raytheon Raylink and Aviator 2.4/PRO
802.11 FH 2Mbps wireless PCMCIA cards.  The cards can be operated in
either ad-hoc or infrastructure modes. The operating mode is
selectable with
.Xr ifconfig 8
through a media option.
.Pp
To communicate with other 802.11 cards a common network id or NWID must
be specified on each station that wishes to participate in the shared
wireless network.  The NWID can
be set with
.Xr ifconfig 8 .
.Pp
The device uses IEEE 802.11 standard Frequency Hopping Spread Spectrum
signaling and operates in the ranges of 2.400 to 2.4835 Gigahertz.
This frequency range is further restricted by country according to
that country's regulations.  Currently the
.Nm
driver defaults to using the ranges appropriate for the USA.
To change this setting you must define the kernel option
RAY_PID_COUNTRY_CODE_DEFAULT to one of the following values:
.Pp
.Bl -item -compact
.It
.Cd RAY_PID_COUNTRY_CODE_USA
.It
.Cd RAY_PID_COUNTRY_CODE_EUROPE
.It
.Cd RAY_PID_COUNTRY_CODE_JAPAN
.It
.Cd RAY_PID_COUNTRY_CODE_KOREA
.It
.Cd RAY_PID_COUNTRY_CODE_SPAIN
.It
.Cd RAY_PID_COUNTRY_CODE_FRANCE
.It
.Cd RAY_PID_COUNTRY_CODE_ISRAEL
.It
.Cd RAY_PID_COUNTRY_CODE_AUSTRALIA
.El
.Pp
The output power of the transceiver is 100mW and the card's power consumption
is 365 mA @ 5 volts.  The transmission range in open air (line of sight)
is a maximum of 1000 feet (or ~304 meters), and indoors (i.e., with
obstructions) it is a maximum of 500 feet (152 meters).
.Sh HARDWARE
Cards supported by the
.Nm
driver include:

.Sh DIAGNOSTICS
.Bl -diag
.It "ray0: card failed self test: status x"
Indicates the card has failed its initial startup tests.

.Sh BUGS
Currently the infrastructure mode is untested, and authentication
using WEP is unimplemented.
