Glossary

Authentication: A verification that a given user is who claim to be based on userID and password. Authentication will allow a user to access the Air Orange network. Authentication does not trigger any drive mappings or single-sign-on type actions.

Bluetooth™: Bluetooth is a computing and telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can easily interconnect with each other and with home and business phones and computers using a short-range wireless connection.

Enterprise Bluetooth Network: A wireless gateway between mobile devices and the fixed infrastructure, granting mobile users access to the enterprise telephony and data services. The network consists of Bluetooth access points installed at distances pre-configured to create a seamless coverage area across the enterprise. Handover between access points enables the user to maintain a continuous connection while moving from the coverage of one access point to another.

Broadband: A transmission facility having a bandwidth sufficient to carry multiple voice, video or data channels simultaneously.

CDMA (Code Division Multiple Access): A technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In CDMA, a frequency is divided into a number of codes.

CDMA2000: CDMA2000 is a radio transmission technology for the evolution of narrowband cdmaOne/IS-95 to 3rd-generation adding up multiple carriers.

Digital: In digital systems the signals of interest are represented as sequences of numbers, which are processed using mathematical techniques. Digital networks are rapidly replacing analog ones as they offer improved sound quality, and secure transmission and can handle data as well as voice.

DSP (Digital Signal Processors): DSP’s are unique microprocessors that are programmable and massive real-time processing capabilities. DSP technology is fundamental to the technology industries two fastest growing markets - wireless and multimedia.

EDGE (Enhanced Data Rates for GMS Evolution): EDGE is an evolution of GSM and US-TDMA systems. This enhanced modulation will significantly increase network capacity and data rates, enabling value-added Mobile Multimedia services. It provides data rates up to 473 kbit/s.

Fixed to Mobile Convergence (FMC): FMC is currently one of the crucial strategic issues in the telecommunications industry, is the way to connect the mobile phone to the fixed line infrastructure. With the convergence between the mobile and fixed line networks, telecommunications operators can provide services to users irrespective of their location, access technology, and terminal.

GPRS (General Packet Radio System): GPRS will provide packet switched data primarily for GSM based 2G networks. GPRS network elements consists of two main elements: SGSN (Service GPRS Support Node) and GGSN (Gateway GPRS Support Node).

GPS (Global Positioning System): A worldwide radio-navigation system that was developed by the US. Department of Defense. In addition to military it is widely used in marine and terrestrial navigation (for example car navigation systems).

GSM (Global System for Mobile Communications): Originally developed as a pan-European standard for digital mobile telephony, GSM has become the world’s most widely used mobile system.

Third Generation (3G) : The next cellular radio technology design to support wideband data communications. 3G applies high-speed data transfer and state-of-the-art radio terminal technology (third generations systems enable multimedia and are currently in the process of being standardized under 3GPP).

Internet Protocol (IP): A communication protocol commonly utilized by communication hardware comprising the Internet.

MVNO (Mobile Virtual Network Operator): A mobile operator that does not own its own spectrum and usually does not have its own network infrastructure. MVNO’s have business arrangements with Cellular operators to buy minutes of use (MOU) for sale to their own customers.

MP3: A standard technology and format for compressing a sound sequence into a very small file, while preserving the original level of sound quality when it is played. MP3 is the most popular Internet-Audio format and is revolutionizing the music distribution industry by allowing users to download music over the Internet.

MSC (Mobile Switching Center): A mobile switching center is responsible for connecting calls together by switching the digital voice data packets from one network path to another, a process usually called ’call routing’. MSC’s also provide additional information to support mobile service subscribers, including user registration, authentication, and location updating.

Packet Switching Service: A communication system whereby data is divided into packets of set size. Its special feature is that communication between terminals with differing formats is possible since transmission/reception is performed after data has first been stored at the exchange. In contrast to circuit switching where a circuit is occupied until all data transfer has been completed, packet switching improves efficiency through common use of circuits.

PBX (Private Branch Exchange): A private telephone system within an enterprise that switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines.

Smart Phone: A Mobile phone that provides additional information accessing features. Any mobile telephone that combines voice services with data services like e-mail, calendar, and Internet access is called a smart phone.

UTMS (Universal Mobile Telephone System): Third generation telecommunications system based on WCDMA-DS.

WCDMA (Wideband Code Division Multiple Access): A technology for wideband digital radio communications of Internet, multimedia, video and other capacity-demanding applications. WCDMA, developed by Ericsson and others, has been selected for the third generation of mobile telephone systems in Europe, Japan and the United States.

Wi-Fi (wireless fidelity or wireless LAN): Applies to wireless LANs and provides 11 Mbps transmission in the 2.4 GHz band. 802.11b uses only DSSS (Acronym for direct-sequence spread spectrum. DSSS is one of two types of spread spectrum radio.) 802.11b was a 1999 IEEE ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet.
