Node: | A network junction or connection point, typically a computer or |
| workstation. |
Packet: | A unit of data routed between an origin and a destination in a |
| network. |
PLCP: | Physical layer convergence protocol |
PPDU: | PLCP protocol data unit |
Preamble: | The ‘preamble’ is a sequence of bits transmitted at 1Mbps that |
| synchronises wireless transmission within the network. The Short |
| Preamble and header may be used to minimize overhead and, |
| thus, maximize the network data throughput. However, the Short |
| Preamble is supported only by the IEEE 802.11b (High- Rate) |
| standard and not by the original IEEE 802.11standard; meaning that |
| stations using |
| implementing the original version of the protocol. |
PSDU: | PLCP service data unit |
Roaming: | A LAN mobile user moves around an ESS and enjoys a continuous |
| connection to an Infrastructure network. |
RTS: | Request To Send. An |
| station to the receiving station requesting permission to transmit. |
RTS Threshold: | Transmitters contending for the medium may not be aware of each |
| other. RTS/CTS mechanism can solve this “Hidden Node Problem”. |
| If the packet size is smaller than the preset RTS Threshold size, the |
| RTS/CTS mechanism will NOT be enabled. |
SSID: | Service Set Identifier, which is a unique name shared among all |
| clients and nodes in a wireless network. The SSID must be identical |
| for each clients and nodes in the wireless network. |
