Mobile terms glossary




Dual-SIM This specifies whether a device is capable of supporting two SIM cards. The two major types of dual-SIM phones are active and standby. Dual-SIM Standby (DSS) requires the user to specify which of the two SIMs is able to make and receive calls, while Dual-SIM Active (DSA) enables both cards to receive calls at the same time. This latter feature usually requires an additional transceiver for the secondary SIM card, and as such consumes more battery life. More recent models feature Dual SIM Dual Standby (DSDS) technology which enables them to have two active SIMs with only one transceiver.

GSM stands for Global System for Mobile Communication and is the most popular 2G mobile phone standard in the world.
GSM is used by about 80% of all mobile phones - approximately 2 billion people across more than 212 countries.
The widespread use of the GSM standard has made it easy for most mobile phone users to use their phones overseas thanks to roaming agreements between operators using the same GSM standard.
GSM - then labelled Groupe Spécial Mobile was originally conceived back in 1982 as a European standard for mobile phones. The first GSM network went live in 1992 in Finland.
GSM introduced the concept of the SIM card (Subscriber Identity Module card) - a detachable smart card that lets users swap their phone number and contacts between handset.

MMS is an extension of the SMS (Short Message Service) protocol, allowing the exchange of text messages exceeding 160 characters. Unlike SMS, which is text-only, MMS can deliver a variety of media. This media may include up to forty seconds of video, audio, one image, or a slideshow of multiple images. MMS requires a third generation (3G) network to send large MMS messages (though smaller MMS messages may be transmitted over second generation networks using GPRS).

Bluetooth is a low-power wireless networking technology operating in the 2.4 GHz unlicensed Industrial, Scientific and Medical (ISM) band. There are two classes of Bluetooth device — Class 1 devices have higher output power and a range of about 100 meters, and Class 2 devices have lower power and a range of about 10 meters. Bluetooth enables ad hoc networking of up to eight devices (supporting voice and data). The Bluetooth Special Interest Group (SIG) was founded in 1998 by IBM, Intel, Ericsson, Nokia and Toshiba, and is supported by more than 2,500 organizations. The Bluetooth v.1.0 specification was ratified and published in 1999 and supported data rates of up to 1Mbps. Bluetooth Version 2.1, along with its enhanced data rate (EDR) specification, was ratified in March 2007, supporting data rates of up to 3 Mbps, and simplified “pairing” — the process used for securely linking one Bluetooth device to another. It also reduced power consumption, doubling the battery life of headsets and other mobile devices for which the Bluetooth radio consumes a large percentage of the power budget. Version 3.0 (“Seattle”) was adopted by the SIG in April 2009, and the specification included Wi-Fi as an alternative transport layer for large volumes of data, supporting data rates of up to 24 Mbps. The SIG also adopted “Bluetooth low energy,” a new ultra-low-power variant, previously referred to as Ultra Low Power (ULP) Bluetooth and Wibree.

GPRS stands for General Packet Radio Service and was the first popular data standard for mobile phones.
GPRS was used for WAP and MMS messages and offered modest connection speeds - typically 30-40 Kbit/s, although the theoretical maximum is 115 Kbit/s. GPRS is known as a 2.5G technology.
One of the early advantages of GPRS is that it s always on so no connection handshake is needed. It is still very popular, especially in the developing world.

The name of EDGE in full is Enhanced Data rates for GSM Evolution. This is a 2.75G technology further developed from the 2G and 2.5G technologies. Its data transmission speed is higher than that of GPRS and is closer to 3G technology.
