There is a guaranteed minimum throughput for a packet-based network, but the actual throughput realized by a packet-based network node will depend on • the number of users in the network, and • how much traffic is being generated by each node at any given time. The advantage of a packet-based network is that multiple transmissions can travel along the network at the same time, using whatever path is appropriate to the routing from the source to the destination. The most significant characteristic of packet-based networks is the wireless interface access protocols they use, such as CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance), which can result in more efficient use of the aggregate bandwidth by dynamically allocating throughput to nodes based on demand.P-Com DataMetro II supports Point-to-Point, Peer-to-Peer, and Centralized (Star) packet-based network topologies. Each topology has its own optimized wireless protocol.

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. Figure 2-1 Point-to-Point TopologyThe range and interference immunity that can be achieved with packet-based point-to-point topology is maximized by the use of highly directional antennas on both sides of the link.DataMetro II applies native modification of the CSMA/CA protocol for the point-to-point topology. Each node sends its frame immediately after receiving a frame, in which case the delay value is equal to zero. The node that sent the frame will wait for a reply. If there is no reply, it will send the next frame using the standard CSMA/CA protocol.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3((5723((57232/2*<In peer-to-peer topology (unique to packet-based networks), there are three or more nodes, any one of which can communicate directly with any other node. Since each node has direct access to every other node, the time delay for transferring data between nodes is the least for this type of topology, unless WAN traffic is very high. However, this also implies that each node must have a clear communication path to every other node, that is, there must be clear line of sight. An example of a three node peer-to-peer topology is shown in Figure 2-2 on page 2-3.DATAMETRO II DATAMETRO IIEthernet Ethernet

The Star Base acts as a switching device. The Star Remotes communicate with each other through the Star Base.A DataMetro II wireless network with centralized topology can connect up to 127 wireless nodes. The MAC protocol used is a combination of random and polling MAC protocols, with positive Data Link acknowledgment that improves the reliability of frame delivery.Figure 2-3 on page 2-4 shows DataMetro II wireless router nodes in a star topology.DATAMETRO II DATAMETRO IIEthernet EthernetDATAMETRO IIEthernet
WIRELESS NETWORK DESIGNCentralized (Star) Topology2-4 P-Com DataMetro II2Figure 2-3 Star TopologyA directional antenna can be used for the central site if all of the nodes fall in the main lobe of the antenna pattern. Since the remote sites need only communicate with the central site, directional, high gain antennas can be used.The range of a Star topology network can be increased if the remote nodes are all located within a confined sector from the central site. Communication between two remote sites must be relayed through the central node.Medium access contention on the Star Base is resolved by the specific Star Base MAC protocol. The Star Remote sends the data frame only when it gets permission from the Star Base. Each frame regularly transmitted by the Star Base contains the PID (polling ID) of the wireless cluster node. If a polled Star Remote has a frame to transmit, it explicitly sends the frame to the Star Base. The Star Base relays this frame to the Star Remotes indicated by the DID (destination ID) of the original frame. A polled Star Remote does not reply on the PID if it has no frame to transmit.DATAMETRO IIDATAMETRO IIDATAMETRO IIDATAMETRO IIBASE STATION REMOTE STATIONSEthernetEthernetEthernetEthernet

The basic configuration requires• RF channel—all units in the WAN must use the same RF channel. Separate WANs in the same geographic area may need to use different channels. The DataMetro II Model 1280 provides nine channels; the Model 320 provides 14 channels.• PN code—all units in the WAN must use the same PN code. Different PN code sequences reduce interchannel and co-channel interference between networks. The DataMetro II provides eight PN codes. • topology—the Data Metro II provides these topologies: peer-to-peer, point-to-point, centralized (star base and star remote)• reboot—to install the basic configurationYou can set up a basic radio configuration through one of three methods:• through twelve DIP switch positions• through a terminal command line interface• through the Site Manager software application
