Mobile terms glossary
Dual-SIM - A Dual-SIM compatible device means that it can carry two SIM cards simultaneously, typically in two different forms. This feature has yet to make a big impact in North America or Europe, but has found increased popularity in Asian markets and is slowly becoming a standard feature. The first form of Dual-SIM device is a DSS that requires the user to specify which SIM card is the active and which is placed in standby. The second form is DSA which means both SIM cards can work at the same time and both receive calls and perform other tasks.
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 an industry standard for contactless data transmission and communication between two devices. The range is usually 1 to 10 m and rarely more than 100 m. In some cases, distances of up to 200 m are possible.
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.
