Interchangeability With Other Devices - ELSA LANCOM Wireless L-2 Manuel De L'utilisateur

Technical basics R3
always knows which stations are available on the wireless side, and thus knows exactly
how any given data packet is to be handled. This process is also known as bridging.
As mentioned earlier, an Ethernet backbone can also be used to extend the range of a
wireless LAN. In this case, multiple base stations can be incorporated in the same LAN
and configured to the same WLAN domain. When a mobile station wants to establish a
connection with the network, it seeks out and logs onto the base station with the
strongest signal. Two mobile stations logged onto different base stations can thus
communicate with one another even though they are not within direct radio range. The
Ethernet linking the base stations closes the gap.
If a station continues to monitor the radio situation after logging on, it can determine the
relative signal strengths of the base stations and automatically switch over to the
strongest base station at any given time without user intervention. This process is known
as roaming.

Interchangeability with other devices

ELSA LANCOM Wireless devices based on the IEEE 802.11 standard are in principle
interoperable with 802.11 devices from other manufacturers. However, as the 802.11
standard is relatively new and many manufacturers are only just making the transition
from proprietary wireless LAN solutions to 802.11, interoperability cannot be guaranteed
at all times. At the very latest, interoperability can fail due to the modulation process
used: ELSA LANCOM Wireless devices use the so-called direct sequenced spread
spectrum (DSSS) process, while some other manufacturers use the frequency hopping
spread spectrum (FHSS) process. The exchange of data between devices based on FHSS
with those using DSS is not possible as a rule.
