.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:

|
|
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).
