2G |
Second Generation Mobile Phone System. See GSM |
 |
3G |
Third generation mobile communications systems have high-speed
data capabilities and will offer advanced services to users on the
move. These services operate at 2GHz, the third generation
technology used in the UK is called UMTS. |
|
Aerial |
Device designed to radiate and receive electromagnetic energy. |
|
Bluetooth |
An industrial specification for wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group.

GSM |
The international, pan-European operating standard for the second
generation of digital cellular mobile communications. It enables
mobile phones to be used across national boundaries.

technology operating in the UK in the form of UK Interface
Requirement [IR2014]
GSM systems are operated by O2 and Vodafone at 900 and 1800
MHz, and by T-Mobile and Orange at 1800 MHz.

HSPDA |
A 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.4 Mbit/s. Further speed increases are planned for the near future. The networks are then to be upgraded to Evolved HSPA, which provides speeds of 42 Mbit/s downlink in its first release. |
|
Macrocell |
A macrocell provides the main radio coverage infrastructure for a
mobile network. The antennas for macrocells are mounted on
ground-based masts, rooftops and other existing structures, at a
height that provides a clear view over the surrounding buildings and
terrain. Macrocells provide radio coverage over varying distances
dependent upon frequency capacity and clutter. Macrocell base
stations have power outputs of typically tens of watts. |
|
UTMS |
The type of technology used in the UK for the 3G (see Third
Generation) mobile phones have video and multimedia capabilities.
