Mobile terms glossary
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.
3G - Analog cellular phones were the first generation while digital marked the second generation. 3G is loosely defined, but generally includes high data speeds, always-on data access, and greater voice capacity.
The high data speeds are possibly the most prominent feature, and certainly the most hyped. They enable such advanced features as live, streaming video.
There are several different 3G technology standards. The most prevalent is UMTS, which is based on WCDMA (the terms WCDMA and UMTS are often used interchangeably).
The GPU (Graphics Processing Unit) is a specialized circuit designed to accelerate the image output in a frame buffer intended for output to a display.
GPUs are very efficient at manipulating computer graphics and are generally more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
Modern smartphones are equipped with advanced embedded chipsets that can do many different tasks depending on their programming. GPUs are an essential part of those chipsets and as mobile games are pushing the boundaries of their capabilities, the GPU performance is becoming increasingly important.
Bluetooth is a short-range wireless technology used to create PANs (Personal Area Networks) among your devices, and with other nearby devices.
Bluetooth allows you to leave your phone in your pocket, while talking on your phone with a Bluetooth headset - with no wires. You can also exchange contact or scheduling information with other Bluetooth-enabled phones nearby, or send such information to a nearby Bluetooth-enabled printer.
Another common use is to give your laptop computer or PDA wireless high-speed Internet access via Bluetooth and your phone.
Many newer automobiles also have Bluetooth, which can interface with a phone in a pocket, to allow automatic hands-free phone capability.
More innovative uses include playing a game against someone with a similar phone nearby, or using a special Bluetooth pen to send SMS messages by simply writing them on paper.
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.
Wi-Fi is a WLAN (Wireless Local Area Network) technology. It provides short-range wireless high-speed data connections between mobile data devices (such as laptops, PDAs or phones) and nearby Wi-Fi access points (special hardware connected to a wired network).
The older variant of Wi-Fi, 802.11g, is capable of providing speeds of up to 54Mbps and is backwards compatible with 802.11b (providing up to 11Mbps).
The more recent standard is called 802.11n (offering speeds of up to 150Mbps per channel or up to 600Mbps in total). It can be used in the 2.4 GHz or 5 GHz frequency bands, though a receiver needs to have dual-band antenna to operate on both.
