Site Survey
A comprehensive facility study performed by network managers to ensure that
planned service levels will be met when a new wireless LAN, or additional WLAN
segments to an existing network are deployed. Site survey’s are usually
performed by a radio frequency engineer and used by systems integrators to
identify the optimum placement of access points to ensure that planned levels of
service are met. Site surveys are sometimes conducted following the deployment
to ensure that the WLAN is achieving the necessary level of coverage. Site
surveys can also be used to detect rogue access points (unauthorized access
point to the network).
Smart-Switched Ethernet Network
Smart Switched Ethernet (SSE) network is suitable for any communication
pattern between the radios. It efficiently determines whether to broadcast to all
radios or direct to a single radio on a packet by packet basis.
Spectrum
A range of electromagnetic frequencies.
Spread Spectrum
A form of wireless communication in which a signal’s frequency is deliberately
varied. This increases bandwidth and lessens the chances of interruption or
interception of the transmitted signal.
SSI
Service Set Identifier is a sequence of characters unique to a specific network or
network segment that’s used by the network and all attached devices to identify
themselves and allow devices to connect to the correct network when one or
more than one independent network is operating in nearby areas.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address
has two components: the network address, and the host (node or device)
address. For example, consider the IP address 150.215.017.009. Assuming this
is part of a Class B network (with a subnet mask of 255.255.0.0), the first two
numbers (150.215) represent the Class B network address, and the second two
numbers (017.009) identify a particular host on this network.
