Glossary for Nokia 3510i Product Support Site A-G H-N O-Z Accessories A wide variety of additional pieces of equipment to enhance the productivity of wireless phones, including extra batteries and rapid, travel or desktop battery chargers, headset kits, car kits and covers. Access code There are up to six different access codes in your phone: Battery The power source for a wireless phone. Rechargeable batteries such as nickel cadmium, nickel metal hydride and lithium ion are used in wireless phones and communication devices. Bookmark A bookmark consists of an Internet address (mandatory), bookmark title, WAP access point, and, if the service requires, a username and a password. CSD Circuit Switched data. Data transmitted over a dedicated (although usually virtual) channel. The destination address is implicitly defined by the (virtual) circuit that is selected. Data services The ability to access services such as e-mail, faxes and SMS messages using a wireless phone or communicator. EGSM Enhanced GSM. The EGSM operating frequency extends 10 MHz lower than usual on the 900 MHz band. Both the phone and the network must support this feature. GSM Global System for Mobile Communications, or GSM, is the digital transmission technique widely adopted in Europe and supported in North America for PCS. GSM uses 1900 MHz in the Americas, and 900 MHz and 1800 MHz in Europe. GPRS General Packet Radio Service. With GPRS you can be online all the time. You can be continuously connected to data networks and use your favorite information and entertainment services. It also provides immediate connectivity and higher data throughput than before, so information retrieval is more accessible and convenient. The main initial use for GPRS is to have it as a bearer for WAP services. In GPRS technology the data is sent in "packets"; this is well suited to the sporadic nature of data applications. GPRS can also be used as a bearer for PC applications in a similar way as CSD and HSCSD are used. HSCSD High Speed Circuit Switched Data. The most important feature of this technology is the increased speed. This makes connection times shorter and the use of current applications more convenient and faster. Data connections can be up to four times faster than earlier, which means that applications such as mobile navigation services using maps and graphics become more attractive. As HSCSD is 'circuit switched', it is more suited to applications such as video conferencing and multimedia than applications that send data in bursts such as e-mail. HSCSD allows wireless data to be transmitted at 43.2 kilobits per second over GSM networks. This is comparable to the transmission rates of usual modems via fixed telephone networks today. IP address Internet protocol address. A unique string of numbers that identifies a computer on the Internet. Shown in groups separated by periods, like this: 123.456.789.012. ISDN ISDN connections are a way to establish a data call between your phone and your access point. ISDN connections are digital from end to end and as such offer quicker set-up times and faster data rates than analog connections. In order to use ISDN, both your Internet service provider and network operator must support them. Java™ technology Java™ is a programming language developed by Sun Microsystems. Some versions of Java™ are likely to be used in the creation of wireless services. LCD screen Liquid Crystal Display screens have low energy requirements and are generally easy to read. LCD screens are made by sealing a liquid compound between two pieces of glass and/or a filter. The screen has hundreds or thousands of dots that are charged or not charged, which makes them reflect or not reflect light to form letters, characters and numbers. Some LCD screens have an electroluminescent panel behind them and are termed "backlit." Li-Ion Refers to a type of battery, a Lithium-Ion battery, used to power wireless communication devices. Li-Ion batteries are lighter weight than earlier battery types, have a relatively long cycle life and generally do not suffer from memory effect. Messaging Using various products, services and technologies to transfer messages from one person to another, or from one device to another such as traditional numeric or alphanumeric paging, e-mail or short messages (SMS) delivered to wireless devices. MIDI Musical Instrument Digital Interface. A communications protocol originally designed to allow synthesizers to communicate with computers and each other. MMS Multimedia Messaging Service (MMS) is a new standard that is being defined for use in advanced wireless terminals. The service allows for non-real-time transmission of various kinds of multimedia contents like images, audio, video clips, etc. Mobile phone A term often used interchangeably with cellular phone or wireless phone. Initially, a mobile phone referred to a phone attached to a vehicle, the vehicle's battery and had an external antenna. Mobile phones were distinguished from transportable, portable, cordless and personal phones. Network In the wireless industry, a network refers to the infrastructure enabling the transmission of wireless signals. A network ties things together and enables resource sharing. Over the Air services (OTA) Over-The-Air (OTA) download of ringing tones, picture messages, and other content to your mobile phone. PIN Code Personal Identification Number. In the context of wireless devices, the PIN is a code used in conjunction with a SIM card to complete a call or data transmission. Polyphonic ringing tones Polyphonic ringing tones consist of several sound components played at the same time like a real melody through a speaker. SIM card Subscriber Identity Module. A small, flat electronic chip on a plastic card. A module that is inserted into mobile equipment for subscriber identification and other security-related information. The SIM is considered part of the mobile station. It contains security-related information, other subscriber-related information and algorithms. Security code A number used to prevent unauthorized or accidental alteration of data programmed into wireless phones. The security code can be used by the owner of a phone to change the lock code. Service provider Telecommunications company that offers its users telecommunication services. May or may not be the same company that provides the radio masts. SMS Short Message Service is a feature available with some wireless phones; it allows users to send and/or receive short alphanumeric messages. Standby time The length of time a wireless phone or communicator is fully charged, turned on and ready to send and receive calls or data transmissions. Standby time, once stated in only hours and minutes, can now be extended to many days with current phone models. Standby time is affected by the amount of time the phone is used for talking because talking on a phone draws more energy from a battery than standby time does. Wireless devices depend on batteries for power; batteries slowly discharge their power and must be recharged and eventually replaced. Talk time The length of time a wireless device may be engaged in transmission (phone conversations, sending or receiving data) before it runs out of battery power. Talk time, expressed in hours and minutes, is much shorter than standby time because transmission requires more power. Therefore, standby time is effected by the amount of time the phone is used for talking. Wireless devices depend on batteries for power; batteries slowly discharge their power and must be recharged and eventually replaced. VGA Video Graphics Array. Supports pixel addressabilities of up to 640 x 480 x 16. This is the de facto video standard and consists of a number of video modes. WAP Wireless Application Protocol is a protocol developed to allow intelligent transmission of optimized Internet content to wireless phones. Wireless Without wires. Communication without any physical connections between the sender and the receiver using the radio frequency spectrum (airways) and hardware, software and technologies to transmit information. WML Wireless Markup Language, a markup language (like HTML), however optimized for wireless use |
