RSQ SYNC POWER DATAMETRO II Figure 1-1 Data Metro II The P-Com DataMetro II is a wireless remote access router with an embedded computing engine. The radio is based on direct sequence spread spectrum technology, operating in the 2400 MHz to 2483.5 MHz RF band. DataMetro II uses time division multiple access (TDMA) to provide access to the wireless media.
1 PRODUCT OVERVIEW Product Description price constraints. The wireless network can be dynamically reconfigured to provide new permanent or temporary services. Adding or removing nodes does not affect network operation. The DataMetro II lowers networking costs by combining routing and wireless transceiver functions in a single package. It lowers unit cost by using an embedded computing engine rather than an external PC.
Product Features .....
1 PRODUCT OVERVIEW Product Features deployed quickly, since no license is required in many countries. Where wired WAN solutions are costly or not available, the Data Metro provides a solution to support geographically dispersed enterprises and network service providers.

In a packet-based point-to-point topology, two nodes are linked directly. The most common application for this topology would be the interconnection of two LANs. In Figure 2-1, the LANs are connected via a pair of DataMetro II routers.

WIRELESS NETWORK DESIGN DATA M E T RO II Ethernet Ethernet DATA M E T RO II Ethernet Figure 2-2 Peer-to-Peer Topology In peer-to-peer topology, since all nodes need to talk to each other, the range is dependent on the type of antennas used and the local terrain. Longer ranges can be achieved by using directional antennas with power splitters to connect to all sites. &(175$/,=(' 67$5 7232/2*< ..................................................
