cellular network
communication network where the last link is wireless
code division multiple access
channel access method for radio communication, allowing many transmitters to send information over one channel using spread spectrum technology and a special coding scheme; used in GPS, cdmaOne, CDMA2000, UMTS etc
MIMO
thumb|MIMO exploits multipath propagation to multiply link capacity.
time-division multiple access
channel access method for shared-medium networks
spread spectrum
spreading the frequency domain of a signal
frequency-hopping spread spectrum
radio signal transmission method invented by Hedy Lamarr
handover
In cellular telecommunications, handover, or handoff, is the process of transferring an ongoing call or data session from one channel connected to the core network to another channel. In satellite communications it is the process of transferring satellite control responsibility from one earth station to another without loss or interruption of service.
mobile ad hoc network
continuously self-configuring, infrastructure-less network of mobile devices connected wirelessly;kind of wireless ad hoc network (WANET) that usually has a routable networking environment on top of a Link Layer ad hoc network
cognitive radio
radio that can be programmed and configured dynamically to use the best wireless channels in its vicinity to avoid user interference and congestion
spectral efficiency
information rate that can be transmitted over a given bandwidth
diversity scheme
methods to improve communications reliability
trunked radio system
class of a radio system
single-frequency network
Group of electronic media outlets that broadcasts data along the same number of cycles
multi-user MIMO
set of multiple-input and multiple-output technologies for wireless communication, in which a set of users or wireless terminals, each with one or more antennas, communicate with each other
