.Sh NAME
|
|
.Nm ral
|
|
.Nd "Ralink Technology IEEE 802.11 wireless network driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ral"
|
|
.Cd "device wlan"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_ral_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports PCI/CardBus wireless adapters based on the Ralink Technology
|
|
RT2500, RT2501, and RT2600 chipsets.
|
|
.Pp
|
|
The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink.
|
|
It consists of two integrated chips, a RT2560 MAC/BBP and a RT2525 radio
|
|
transceiver.
|
|
.Pp
|
|
The RT2501 chipset is the second generation of 802.11b/g adapters from Ralink.
|
|
It consists of two integrated chips, a RT2561 MAC/BBP and a RT2527 radio
|
|
transceiver.
|
|
This chipset provides support for the IEEE 802.11e standard with multiple
|
|
hardware transmission queues and allows scatter/gather for efficient DMA
|
|
operations.
|
|
.Pp
|
|
The RT2600 chipset consists of two integrated chips, a RT2661 MAC/BBP and a
|
|
RT2529 radio transceiver.
|
|
This chipset uses the MIMO (multiple-input multiple-output) technology with
|
|
multiple antennas to extend the operating range of the adapter and to achieve
|
|
higher throughput.
|
|
MIMO is the basis of the forthcoming IEEE 802.11n standard.
|
|
.Pp
|
|
The transmit speed is user-selectable or can be adapted automatically by the
|
|
driver depending on the received signal strength and on the number of hardware
|
|
transmission retries.
|
|
.Sh HARDWARE
|
