transmitted data extracted. The transmission method used by
the access point is called Direct Sequence Spread Spectrum
(DSSS) and operates in a range of the radio spectrum between
2.4 GHz and 2.5 GHz for transmission. See the expert
technical specifications for more details on wireless operation.
Antennas
Direct the external antenna to allow optimization of the wireless
link. If the antenna is erect, wireless links in the horizontal
plane are favored. Please note that the antenna characteristics
are influenced by the environment, that is, by reflections of the
radio signal against walls or ceilings. It is advisable to use the
received signal strength as indicated by the wireless client
manager to optimize the antenna position for the link to a given
client. Concrete walls weaken the radio signal and thus affect
the connection.
Range
Range should not be a problem in most homes or small offices.
If you experience low or no signal strength in some areas,
consider positioning the Router in a location between the
WLAN devices that maintains a roughly equal straight-line
distance to all devices that need to access the Router through
the wireless interface. Adding more 802.11g access points to
rooms where the signal is weak can improve signal strength.
Read the section about placement of the Router titled Location
in the next chapter, Hardware Installation, for more information.
Radio channels
The 802.11g standard allows several WLAN networks using
different radio channels to be co-located. The OV804WV
supports multiple radio channels and is able to select the best
radio channel at each startup. You can choose to set the
channels automatically or manually.
The different channels overlap. To avoid interference with
another access point, make sure that the separation (in terms
