Hands-free:
The operation of a cellular phone without using the handset; usually installed in vehicles.
Handoff:
The transfer of control of a cellular phone call in progress from one cell to another, without any discontinuity
HCS
Hierarchical Cell Structure; the architecture of a multi-layered cellular network where subscribers are handed over from the macro to the micro to the pico layer depending on the current network capacity and the needs of the subscriber
HDLC - High level Data Link Control
HIPERLAN: - High Performance Radio Local Access Network
(a wireless local area network being standardised by ETSI), (Also HIPERLAN2)
HLR - Home Location Register
( the database within a GSM network which stores all the subscriber data.A vital element in the roaming process)
HR - Half Rate Traffic
HSCSD - High Speed Circuit Switched Data
( a special mode in GSM networks which provides higher data throughput By cocatenating a number of timeslots, each delivering 14.4kbit/s, much higher data speeds can be achieved)
HSPSD - High Speed Packet Switched Data
HSCSD - High Speed Circuit Switched Data System
( this enables the transmission of data over current GSM networks at speeds up to 43.2 kbps. HSCSD enables such high speeds by using multiple channels.)
