|

|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm cnw
|
||
|
|
interface provides access to a theoretical 1 Mb/s wireless ethernet network
|
||
|
|
based on the Netwave AirSurfer Wireless LAN (formerly known as the Xircom
|
||
|
|
Netwave Wireless LAN).
|
||
|
|
It use 32K of I/O memory mapped to the card along with either 16 I/O ports
|
||
|
|
or 4K of additional I/O memory for access to command registers. The
|
||
|
|
driver currently only supports the use of the additional 4K of I/O memory.
|
||
|
|
.Pp
|
||
|
|
In use, the cards appear to achieve up to a 420Kb/s transfer rate, though
|
||
|
|
a transfer rate between 250Kb/s and 350Kb/s is typical. The card
|
||
|
|
operates in the 2.4Ghz frequency range and is subject to interference
|
||
|
|
from microwaves as well as earth.
