RAY(4) BSD Programmer's Manual RAY(4)NAMEray - Raytheon Raylink / WebGear Aviator IEEE 802.11FH 2Mbps Wireless
SYNOPSIS
ray* at pcmcia? function ?
option RAY_PID_COUNTRY_CODE_DEFAULT=RAY_PID_COUNTRY_CODE_USA
DESCRIPTION
The ray device driver supports the Raytheon Raylink and Aviator 2.4/PRO
802.11 Frequency Hopping 2Mbps wireless PCMCIA cards. The cards can be
operated in either adhoc or infrastructure modes. The operating mode is
selectable with ifconfig(8) through a media option.
Cards supported by the ray driver include:
WebGear Aviator 2.4
WebGear Aviator PRO
Raytheon Raylink WLAN
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 ifconfig(8).
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 ray 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:
RAY_PID_COUNTRY_CODE_USA
RAY_PID_COUNTRY_CODE_EUROPE
RAY_PID_COUNTRY_CODE_JAPAN
RAY_PID_COUNTRY_CODE_KOREA
RAY_PID_COUNTRY_CODE_SPAIN
RAY_PID_COUNTRY_CODE_FRANCE
RAY_PID_COUNTRY_CODE_ISRAEL
RAY_PID_COUNTRY_CODE_AUSTRALIA
The output power of the transceiver is 100mW and the card's power con-
sumption 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).
Windows drivers may use one of two framing modes for wireless packets,
"translation" and "encapsulation." "Encapsulation" is the only framing
mode available when using some older Windows drivers.
Setting link0 flag on the interface allows the Ethernet2 in 802.11 "en-
capsulation" framing method used by older Windows drivers for the card.
For all other purposes, link0 should not be used, and "translation"
should be selected if you are given the option in a newer Windows driver.
DIAGNOSTICS
ray0: card failed self test: status x Indicates the card has failed its
initial startup tests.

The ray device driver first appeared in NetBSD 1.5. OpenBSD support was
added in OpenBSD 2.7.
AUTHORS
The ray driver was written by Christian E. Hopps <chopps@netbsd.org> and
ported to OpenBSD by
Michael Shalayeff <mickey@openbsd.org>. Support for interoperating with
newer Windows driver was added by
Steve Weiss <srw@alum.mit.edu>.
BUGS
Currently the infrastructure mode is untested, and authentication using
WEP is unimplemented.
Firmware version 4 does not interop with version 5 or higher.
