AGPS
Assisted GPS, generally abbreviated as A-GPS or aGPS, is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system.
BGA
A ball grid array (BGA) is a type of surface-mount packaging used for integrated circuits.
BSC
Base Station Controller - This is a part of the GSM network. It is connected via Abis interface to the BTS. Upstream connection is to the MSC. The BSC provides, classically, the intelligence behind the BTSs.
BTS
Base transceiver station (BTS) - This is the part between the MS and BSC in a GSM network. It is interfaced to the BSC using the Abis protocol.
FBGA
FINE ball grid array - see (Glossary#BGA)
FPGA
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable". (not used in v1)
GPRS
General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications (GSM).
GPS
The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible by anyone with a GPS receiver with some technical limitations which are only removed for military users.
GTA01
Internal codename of the first phone hardware release, the Neo 1973.
GTA02
Internal codename of the second phone hardware release, the Neo FreeRunner.
MSC
Mobile switching center (MSC) - A major component of the GSM Network.
PLMN
Acronym for Public Land Mobile Network what your mobile phone almost certainly connects to.
