[wiki:Internal/Mapping/Topologies Back] = Topology1: Simple Point to point link with configurable PER = This represents the simplest basic topology comprising a point to point link (either infrastructure AP to client or peer to peer) with a configurable packet error rate for certain packet sizes [[Image(topo1.png)]] The configurable PER (for a particular packet size) is obtained by introducing AWGN noise at preset power levels on the channel used by the link. In order to achieve this, the following steps are needed * Fix the packet size to X bytes. (where X ∈ (80, 512, 1024) bytes) * Fix the PHY rate to Y Mbps (where Y ∈ (6, 9, 12, 18, 24, 36, 48, 54) Mbps) * Cycle through the noise levels and measure the PER for the given packet size and PHY rate From these experiments, a set of feasible PERs can be obtained for the available noise levels.
