NAMEray — Raytheon Raylink / WebGear Aviator IEEE 802.11 2Mbps Wireless
SYNOPSISray* at pcmcia? function ?
DESCRIPTIONThe 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 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:
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).
HARDWARECards supported by the ray driver include:
- WebGear Aviator 2.4
- WebGear Aviator PRO
- Raytheon Raylink WLAN
- ray0: card failed self test: status x
- Indicates the card has failed its initial startup tests.
HISTORYThe ray driver first appeared in NetBSD 1.5.
AUTHORSThe ray driver was written by <chopps@NetBSD.org>.
BUGSCurrently the infrastructure mode is untested, and authentication using WEP is unimplemented.
