Point-to-Multipoint
A wireless network in which one point (the access point) serves multiple other
points around it. Indoor wireless networks are all point-to-multipoint, and long-
range wireless networks that serve multiple clients usually employ either a single
omnidirectional antenna or multiple sector antennas.
Point-to-Point Network
A network consisting of a single Master radio and a single Remote radio. All data
from the Master is received and acknowledged by one Remote. All data from the
single Remote is received and acknowledged by the Master radio.
Poll
A method of electronic communication.
Power Supply
Device that supplies electrical power to the I/O chassis containing the processor,
coprocessor, or other modules.
Protocol
The language or packaging of information that is transmitted between nodes on a
network.
Q
QoS
Quality of Service. Required to support wireless multimedia applications and
advanced traffic management. QoS enables Wi-Fi access points to prioritize
traffic and optimize the way shared network resources are allocated among
different applications.
R
RADIUS
Remote Access Dial-In Service. This describes a general method for allowing
remote users access to a network. It authenticates the user, specifies passwords
and access rights to network resources. It also keeps track of accounting for
when and how long the user is logged onto the network. It was originally used for
dial-in users, accessing corporate networks via modems. It is now being
specified as part of the 802.11i standard to control access of users to wireless
networks. Any of several protocols can be used by the wireless client to
communicate with the RADIUS server to gain access to the network resources.
These protocols include EAP-TLS (Windows), LEAP (Cisco) and EAP-TTLS.
Range
The distance covered by a wireless network radio device. Depending on the
environment and the type of antenna used, Wi-Fi signals can have a range of up
to a mile.
