Umts Universal Telecommunications Communication Technology
|
We have all heard the buzzwords that have come into our lives with the elaboration of the Wireless industry. But do you recognise what they mean? It is mixing up to say the least so let’s try to clarify a great deal of of the terminology affiliated to the technology. Wireless – refers to telecommunications in which electromagnetic waves carry a signal over share of the communications path. 1G – First Generation, Cellular systems based on analog technology. 2G – Cellular wireless based on digital technology. 2G schemes offer increased voice quality and capacity to handle more calls. 3G – Systems designed to increase voice capacity and provide high-speed data. 3G will enable users with high-speed data, progressed international roaming and intensified multimedia capabilities. CDMA provides the basis for 3G technology, which has been imposed as CDMA2000® and WCDMA (UMTS). Air card – Aircard® is a registered trademark owned by Sierra Wireless and has become synonymous with a wireless PC card. Blackberry – Two-way wireless device that allows users to check email and voice mail (via text), and page other users using a wireless network service. Blackberry® users ought to subscribe to a wireless service that provides selective information transmission service. Bluetooth Wireless Technology – is the low-power, short-range radio engineering science that allows digital electronic widgets such as mobile phones, headsets, PDAs, notebook PCs and even cars to “talk” to each other without wires and without apparent effort transfer files at high speed. CDMA – Code Division Multiple Access, CDMA cellular schemes employ a single frequency band for all traffic, differentiating the person transmissions by assigning them distinguishable codes before transmission. Cellular – Analog or digital communications in which a subscriber has a wireless connection from a mobile handset to a comparatively nearby transmitter. As the cellular telephone user moves from one cell or area of coverage to another, the telephone is efficaciously passed on to the local cell transmitter. EDGE – Enhanced Data GSM Environment- a rapidly and without delay version of the Global System for Mobile (GSM) wireless service GPS – Global Positioning System – a emplacement scheme based on a constellation of US Department of Defense satellites. GSM – Global System for Mobile Communication is a digital mobile telephone technology GPRS – General Packet Radio Service, a packet-based wireless communicating service that provides neverending connection to the Internet for mobile phone and computer users. iDEN – Integrated Digital Enhanced Network, A proprietary technology based on the TDMA popular that allows users to access phone calls, two-radio transmissions, paging and info from one wireless device. Nextel Communications® uses the iDEN® standard as the basis for it is networks. Streaming – an Internet expression for the one-way transmission of video and audio TDMA – Time Division Multiple Access, a technique for multiplexing multiple users onto a single channel on a single carrier by splitting the carrier into time slots and allocating these on a as-needed basis UMTS – Universal Mobile Telecommunications System, a broadband, packet-based system supplying a consistent set of services to mobile computer and phone users no matter where they are located in the world WAP – Wireless Application Protocol – a set of communicating protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, may be applied for Internet access |
