Mobile terms glossary
Dual-SIM - As a SIM links a phone to a specific carrier (service provider), billing account, and phone number, a dual-SIM phone can be linked to two different phone numbers associated with two different billing accounts. Those accounts and phone numbers can be with different carriers, and even in different countries.
One common use is to use one phone with both a business phone number (and account and a separate personal line. Another use is to have accounts with carriers in two different countries, in order to take advantage of favorable rates for local versus international calls, or to permit favorable rates for people calling you, by have local phone numbers in two countries.
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).
Enhanced messaging service (EMS) uses some features defined in the Short Message Service (SMS) specification to enhance the user experience when sending messages. A thin client is added to the mobile phone and by using standard SMS parameter fields, such as the user data header, binary-encoded and concatenated messages can be sent that display enriched content, such as italicized, emboldened or underlined text, predefined sounds, monophonic tunes and static or animated images.
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.
