RAY(4) BSD Kernel Interfaces Manual RAY(4)
ray -- Raytheon Raylink / WebGear Aviator IEEE 802.11 2Mbps Wireless
ray* at pcmcia? function ?
The ray 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 ifconfig(8) through a media option.
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
The device uses IEEE 802.11 standard Frequency Hopping Spread Spectrum signaling and oper-
ates 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:
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
Cards supported by the ray driver include:
WebGear Aviator 2.4

The ray driver first appeared in NetBSD 1.5.
The ray driver was written by Christian E. Hopps <chopps@NetBSD.org>.
Currently the infrastructure mode is untested, and authentication using WEP is unimple-
