Spectrum (DSSS) and operates in a range of the radio spectrum between 2.4GHz
and 2.5GHz for transmission. See the expert technical specifications for more
details on wireless operation.
3.5.1.3 Antennas
Direct the external antenna to allow optimization of the wireless link. If for example
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.
3.5.1.4 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.
3.5.1.5 SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to
roam within the range of the network. Wireless devices that wish to communicate
with each other must use the same SSID. Several access points can be set up
using the same SSID so that wireless stations can move from one location to
another without losing connection to the wireless network. The Modem operates in
Infrastructure mode. It controls network access on the wireless interface in its
broadcast area. It will allow access to the wireless network to devices using the
correct SSID after a negotiation process takes place. By default the Modem
broadcasts its SSID so that any wireless station in range can learn the SSID and
ask permission to associate with it. Many wireless adapters are able to survey or
scan the wireless environment for access points. An access point in Infrastructure
mode allows wireless devices to survey that network and select an access point
