| Term | Description |
| GAIT | Generic Access Profile; a DECT term. |
| GB | The interface between the PCU and the SGSN in a GSM/GPRS network. |
| Gb Interface | The interface between SGSN and BSS. |
| Gbit/s | A unit of data transmission rate equal to one billion bits per second. |
| Gc | The interface between the GGSN and the HLR in a GSM/GPRS network. |
| Gd | The interface between the SGSN and the SMSC in a GSM/GPRS network. |
| Geostationary | Refers to a satellite in equatorial orbit above the earth which appears from the surface to be stationary. |
| GERAN | GSM-EDGE Radio Access Network; the name for the evolution of GSM towards 3G based on EDGE. |
| Gf | The interface between the SGSN and the EIR in a GSM/GPRS network. |
| GGRF | GSM Global Roaming Forum. |
| GGSN | Gateway between a cellular network and a IP network. |
| GHz | A unit of frequency equal to one billion Hertz per second. |
| Gi | The interface between the GGSN and the Internet in a GPRS network. |
| GMPCS | Global Mobile Personal communications by Satellite. |
| GMSC | Gateway Mobile Services Switching Center; the gateway between two networks. |
| Gn | The interface between the GGSN and the GGSN and the SGSN in a GPRS network. |
| GOS | A measure of the success a subscriber is expected to have in accessing a network to complete a call. The grade of service is usually expressed as percentage of calls attempted by the subscriber during the busy-hour that are blocked due to insufficient network resources. |
| Gp | The interface between the GGSN/SGSN and the Border Gateway in a GPRS network. |
| GPRS | General Packet Radio Service. A packet-based wireless communication service based on Global System for Mobile (GSM) communication that deliver effective data rates up to 50 Kbps and continuous connection to the data services for mobile phone and computer users, as well as telematics applications. The higher data rates allow users to send multimedia messages, and interact with multimedia Web sites and similar applications using mobile handheld devices as well as notebook computers. GPRS complements existing services such as Short Message Service (SMS) and circuit-switched cellular phone connections. |
| GPRS accelerators | Offer only very limited improvements as far as corporate messaging is concerned, mainly by filtering out graphics and audio compression and do not provide an over-all mechanism for improving GPRS services. |
| GPRS KPIs | Key performance indicators. |
| GPS | Global positioning system; a location systenm based on a constellation of US Department of Defense satellites. Depending on the number of satellites visible to the user, can provide accuracies down to tens of meters. Now being incorporated as a key feature in an increasing number of handsets. |
| Gr | The interface between the GGSN and the SGSN and the HLR in a GPRS network. |
| GRX | GPRS Roaming Exchange. |
| Gs | The interface between the SGSN and the MSC in a GSM/GPRS network. |
| GSM | Global System for Mobile Communication. Originally developed as a pan-European standard for digital mobile telephony, GSM has become the worldds most widely used mobile system. It is used on the 900 MHz and 1800 MHz frequencies in Europe, Asia and Australia, and the MHz 1900 frequency in North America and Latin America. |
| GSM MoU | The GSM Memorandum of Understanding, an agreement signed between all the major European operators to work together to promote GSM. The precursor of the GSM Association. |
| GSM-R | GSM-Railway. A variant of GSM designed to meet the special communications needs of international train operators. |
| GTP | GPRS Tunneling Protocol. Responsible for mobile/initiated network/initiated PDP context activation/deactivation and tunneling of user data between SGSN and GGSN. |
