Ad Hoc wireless LAN is applicable at adepartmental scale for a branch or SOHO operation.BSSIDA specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS mustbe configured with the same BSSID.DHCPDynamic Host Configuration Protocol - a method in which IP addresses are assignedby server dynamically to clients on the network. DHCP is used for Dynamic IPAddressing and requires a dedicated DHCP server on the network.Direct Sequence Spread SpectrumThis is the method the wireless cards use to transmit data over the frequencyspectrum. The other method is frequency hopping. Direct sequence spreads the dataover one frequency range (channel) while frequency hopping jumps from one narrowfrequency band to another many times per second.ESSIDAn Infrastructure configuration could also support roaming capability for mobileworkers. More than one BSS can be configured as an Extended Service Set (ESS).Users within an ESS could roam freely between BSSs while served as a continuousconnection to the network wireless stations and Access Points within an ESS must beconfigured with the same ESSID and the same radio channel.EthernetEthernet is a 10/100Mbps network that runs over dedicated home/office wiring. Usersmust be wired to the network at all times to gain access.GatewayA gateway is a hardware and software device that connects two dissimilar systems,such as a LAN and a mainframe. In Internet terminology, a gateway is another namefor a router. Generally a gateway is used as a funnel for all traffic to the Internet.

In networks with StaticIP address, the network administrator manually assigns an IP address to eachcomputer. Once a Static IP address is assigned, a computer uses the same IPaddress every time it reboots and logs on to the network, unless it is manuallychanged.Transmission Control Protocol / Internet Protocol (TCP/IP)TCP/IP is the protocol suite developed by the Advanced Research Projects Agency(ARPA). It is widely used in corporate Internet works, because of its superior designfor WANs. TCP governs how packet is sequenced for transmission the network. Theterm “TCP/IP” is often used generically to refer to the entire suite of related protocols.Transmit / ReceiveThe wireless throughput in Bytes per second averaged over two seconds.Wide Area Network (WAN)A WAN consists of multiple LANs that are tied together via telephone services and / orfiber optic cabling. WANs may span a city, a state, a country, or even the world.Wireless LAN (WLAN)A wireless LAN does not use cable to transmit signals, but rather uses radio orinfrared to transmit packets through the air. Radio Frequency (RF) and infrared are thecommonly used types of wireless transmission. Most wireless LANs use spreadspectrum technology. It offers limited bandwidth, usually under 11Mbps, and usersshare the bandwidth with other devices in the spectrum; however, users can operate aspread spectrum device without licensing from the Federal CommunicationsCommission (FCC)
