Campus-REX2 RS Interface Card User Manual

Point-to-Point LAN Extension

As organizations move or change, LANs also evolve and may become
fragmented or physically separated. The Campus-REX2 provides a
lower-cost alternative to other LAN-extension solutions. The Campus-REX2
provides a built-in 10/100Base-T LAN interface that eliminates the need for
other internetworking devices while providing 30 times the performance of
other sub-rate wireless connectivity options, as shown in the following figure.
