Grant Service UGS The UGS is designed to support real-time service
flows that generate fixed size data packets on a
periodic basis, such as TDM and Voice over IP
without silence suppression. The service offers fixed
size grants on a real-time periodic basis, which
eliminate the overhead and latency of Subscriber
requests and assure that grants are available to meet
the flow’s real-time needs.
Uplink The direction from a subscriber to the RedMAX base
station base station.
Uplink Channel
Descriptor UCD A UCD message is transmitted by the RedMAX base
station base station at a periodic interval to define the
characteristics of an uplink physical channel. A
separate UCD message is transmitted for each active
uplink channel associated with the downlink channel.
Uplink Interval
Usage Code UIUC An Interval Usage Code specific to an uplink (to
RedMAX base station base station from subscriber).
Uplink Map: UL-MAP A set of information that defines the entire map for the
uplink. Based on that, Subscribers send data
according to the scheduled opportunities. The UL-
MAP is composed from Information Elements.
VSWR VSWR Voltage standing wave ratio (VSWR) is the ratio of the
amplitude of a partial standing wave at an antinode
(maximum) to the amplitude at an adjacent node
(minimum).
Wireless Fidelity Wi-Fi Wireless fidelity is used generically when referring of
any type of 802.11 network, whether 802.11b,
