Explanation
RTS request to send, CTS clear to send (in 802.11 standard)
In Ethernet networks, a section of a network that is bounded by bridges,
routers or switches. Dividing a LAN segment into multiple smaller
segments is one of the most common ways of increasing available
bandwidth on the LAN.
Service Location Protocol. A method of organizing and locating the
resources (such as printers, disk drives, databases, e-mail directories, and
schedulers) in a network. Using SLP, networking applications can discover
the existence, location and configuration of networked devices.
With Service Location Protocol, client applications are 'User Agents' and
services are advertised by 'Service Agents'. The User Agent issues a
multicast 'Service Request' (SrvRqst) on behalf of the client application,
specifying the services required. The User Agent will receive a Service
Reply (SrvRply) specifying the location of all services in the network which
satisfy the request.
For larger networks, a third entity, called a 'Directory Agent', receives
registrations from all available Service Agents. A User Agent sends a
unicast request for services to a Directory Agent (if there is one) rather than
to a Service Agent.

Structure of Management Information. A hierarchical tree structure for
information that underlies Management Information Bases (MIBs), and is
used by the SNMP protocol. Defined in RFC1155 and RFC1442 (SNMPv2).
Station ManagemenT. The object class in the 802.11 MIB that provides the
necessary support at the station to manage the processes in the station such
that the station may work cooperatively as a part of an IEEE 802.11
network. The four branches of the 802.11 MIB are:
dot11smt - objects related to station management and local
configuration
dot11mac - objects that report/configure on the status of various MAC
parameters
dot11res - Objects that describe available resources
dot11phy - Objects that report on various physical items.
Simple Network Management Protocol. A set of protocols for managing
complex networks. SNMP works by sending messages, called protocol data
units (PDUs), to different parts of a network. SNMP-compliant devices,
called agents, store data about themselves in Management Information
Bases (MIBs) and return this data to the SNMP requesters.
SNMP includes a limited set of management commands and responses.
The management system issues Get, GetNext and Set messages to retrieve
single or multiple object variables or to establish the value of a single
variable. The managed agent sends a Response message to complete the
Get, GetNext or Set.
An event notification sent by the SNMP managed agent to the management
system to identify the occurrence of conditions (such as a threshold that
exceeds a predetermined value).
