spread spectrum
A radio transmission technology that spreads the user information over a much
wider bandwidth than otherwise required in order to gain benefits such as
improved interference tolerance and unlicensed operation.
SSID
Service set identifier (also referred to as Radio Network Name). A unique
identifier used to identify a radio network and which stations must use to be able
to communicate with each other or to an access point. The SSID can be any
alphanumeric entry up to a maximum of 32 characters.
T
transmit power
The power level of radio transmission.
U
UNII
Unlicensed National Information Infrastructure—regulations for UNII devices
operating in the 5.15 to 5.35 GHz and 5.725 to 5.825 GHz frequency bands.
UNII-1
Regulations for UNII devices operating in the 5.15 to 5.25 GHz frequency band.
UNII-2
Regulations for UNII devices operating in the 5.25 to 5.35 GHz frequency band.
UNII-3
Regulations for UNII devices operating in the 5.725 to 5.825 GHz frequency
band.
unicast packet
A single data message (packet) sent to a specific IP address.
UPoE
Cisco Universal Power Over Ethernet (UPOE) extends IEEE PoE+ standard by
doubling the power per port to 60W over a single standard Ethernet Cable. It
allows the consolidation of 60 watts power on a single Ethernet (CAT5E or
higher) cable, or in short 60W per access switch port.
W
WDS
Wireless Domain Services. An access point providing WDS on your wireless
LAN maintains a cache of credentials for CCKM-capable client devices on your
wireless LAN. When a CCKM-capable client roams from one access point to
another, the WDS access point forwards the client's credentials to the new access
point with the multicast key. Only two packets pass between the client and the
new access point, greatly shortening the reassociation time.
WEP
Wired Equivalent Privacy. An optional security mechanism defined within the
802.11 standard designed to make the link integrity of wireless devices equal to
that of a cable.
