Radio penetration is greatly influenced by the building material used in construction. For
example, drywall construction allows greater range than concrete blocks. Metal or steel
construction is a barrier to radio signals.
Enhancing Coverage
The system architecture options of the wireless station and LG Access Points provide for
a variety of coverage alternatives and flexibility. The system can be designed to provide
a wide coverage area with minimal overlap or coverage with heavy overlap. The latter
improves system performance and protection against downtime in the event of a
component failure. By arranging the LG Access Points so the overlap in coverage area
is minimized, a large area can be covered with minimal system cost. The total bandwidth
available to each mobile station will depend on the amount of data each mobile station
desires to transfer and the number of stations located in each cell. Seamless roaming is
supported as a mobile station moves in and out of range of each LG Access Point,
thereby maintaining a constant connection to the wired LAN. Each device in the radio
network must be configured with the same Service Set Identifier (SSID) to provide the
roaming capability. Multiple systems can operate in the same vicinity. The architecture
provides multiple channels, which can coexist in the same area with virtually no
interference to each other. In this mode, each system must be configured with different
Service Set Identifiers (SSID) and different channels, which prevent clients from roaming
to LG Access Points of a different wireless system.
