|
| Code Division Multiple Access (CDMA)
|
|
CDMA separates communications by code. Voice is broken into digitised bits, and groups of bits are tagged with a code. Each code is associated with a single call in the network. Groups of bits from one call are randomly transmitted along with those of other calls. Then they are reassembled in the correct order to complete the conversation.
|
|
The geographic area determining the signal range from each base station.
|
|
Criminals with specialist equipment can capture identity codes from analogue mobile phones and create "clone" IDs allowing them to charge calls to your mobile phone account. Most mobile phone companies will normally refund the costs of such stolen phone calls - it is essential to check your bills carefully. Digital phones cannot be cloned in this way and are less vulnerable to eavesdropping than analogue phones. |
|
A conference call allows you to bring two or more people into the call at once, the exact number of people you can join into the call depends on the model of the mobile phone. This service must be activated by the network provider. |
|
Sometimes a one-off connection fee will be charged when you start a contract with one of the networks. Many networks will offer free connection but do check before you sign up. |
|
When a mobile phone usersigns up for a pay monthly/contract tariff, the network provider will require the user to sign up for a minimum term - this is usually 12 or 18 months depending on the details of the offer. We recommend carefully checking the details of the contract before signing up. |
|
Refers to the geographic area determining a network's service to users. |
Also known as X-Net(work)
Cross network refers to using your mobile phone on networks other than the one to which you pay your monthly line rental. It is worth noting that cross network charges are generally much higher than same-network, so it makes sense to coordinate with those you wish to make the most calls to.

|
|
The process of "pulling" (or transferring) information from one computer onto another. For example, when you access a web site, the HTML code and graphics must be downloaded from a remote server onto your computer before you can see the web site. The time it takes to do this depends on the bandwidth of your connection to the Internet. The opposite action is upload.
|
|
Mobile communications work in 'bands' of frequencies. Mobile phones which operate on both the GSM 900 and GSM 1800 (MHz) bands are known as "dual-band" phones. This gives a greater choice of networks when roaming.

The module allows the owner to insert a bank Smart Card so that online e-commerce transactions can be made directly from the phone.
|
|
EDGE (Enhanced Data Global Evolution) is an extension of GSM. EDGE gives the mobile telephone user access to increased bandwidth and multimedia services, such as video clips. From the point of view of the operator, the advantage of EDGE is that this technology allows the existing GSM infrastructure to be expanded to EDGE, achieving data transfer speeds almost as high as those of UMTS without the need to buy a UMTS licence or build a completely new infrastructure.
|
|
E-mail, an abbreviation of electronic mail, is a method of sending messages, mail, pictures and information from one Internet user to another. E-mail can also be sent to a large number of addresses at once through a mailing list. Some cellular devices now have in-built functionality to allow users to send and pick up e-mail, enhancing their communication capabilities.

Flash Memory is a type of EEPROM (Electrically Erasable Programmable Read-Only Memory) used in PC Cards and Memory Cards. This type of memory is non-volatile and is often used to store data in devices such as mobile phones, notebook computers, PDAs, and digital cameras. The memory is called 'flash' because multiple memory locations can be written or erased in a single action.
As flash memory is written and erased in 'blocks' of memory, this means equipment using it can operate more quickly when required to read and write several locations at the same time. After a certain number of erasure cycles flash memory devices will eventually wear out, although for most practical applications this is unlikely to be a problem. |
|
Some mobile phones include an integrated FM radio for listening to live-broadcast FM radio stations. Some phones with this feature require that a headset be connected to use this feature, so that the headset wire can be used as an antenna.

Calls to or from a mobile phone get to their destination via antenna located on buildings or masts. Each antenna (usually a group of antenna) is at the centre of what is known as a cell. A group of cells makes up a network. Because the power output from the mobile phones and antenna is relatively low, to communicate over anything but the smallest distances, a call has to be passed from one cell to the next until the signal gets to the intended receiver. Each cell overlaps with the neighbouring cell in the 'network' to allow calls to be passed on.
Network operators are companies that have been granted a licence by the Department of Trade and Industry to operate a telecommunications network. For the most part these are the mobile phone companies such as Orange, O2 and Vodafone.

Most networks offer customers a pay as you go (or pre-pay) option whereby no monthly line rental is paid, but instead credit vouchers are purchased in order to make telephone calls. Handset costs with pay as you go may be slightly higher than pay monthly handset costs as networks do not subsidise this scheme in the same way as they do with pay monthly tariffs.
|
|
Pay monthly is a payment scheme whereby a 12 month (or occasionally 18 month) contract is agreed between the customer and a network. A monthly line rental is paid for a tariff which may include free talk time minutes and text messages. When signing up to a pay monthly tariff, handsets are generally given to the customer at low cost or free.
|
|
A payment scheme whereby a customer pays for 12 months' line rental in advance. The network in return will offer free talk time minutes every month.

Handsfree (or hands-free) is the term used to describe the method of operating a device, such as a mobile phone, PDA or notebook (that is normally handheld), without holding or touching the handset. Some of these devices are fitted with a small speakerphone, which amplifies the voice of the caller and so makes it possible to conduct a conversation on the phone without holding it to the user's ear.
Many handsfree accessories are available, such as headsets and car kits, enabling the user to operate a mobile phone or similar communication devices without using their hands. Handsfree operation is considered to be an essential in-car safety requirement and as of 2003, it became a specific offence to use a handheld phone, or similar device, when driving. Most recent mobile phones now have a handsfree facility fitted as standard, or available as an optional extra.
Handsfree control is made easier in those mobile phones that are designed for operation by voice commands, which enables voice dialling and other menu selections to be made by the use of the voice alone. Bluetooth is another popular method of handsfree communication.
|
|
A feature on a phone that allows the storage of names and telephone numbers in the phone's memory. More advanced phones allow users to store further information such as images, alternative phone numbers and email addresses.

|
| Picture and Video Messaging |
|
The ability to send a photo or video clip from a compatible mobile phone to another mobile phone or email address. The service is sometimes known as MMS, which stands for Multimedia Messaging Service.
|
| Personal Identification Number (PIN) |
|
A PIN is used as a security measure to prevent unauthorised users making calls. You may want to set up a PIN for a variety of uses such as restricting handset access and retrieving voicemail. Each mobile phone network sets the PIN number of their SIM cards to a standard default SIM number. You can change this via your handset if you wish. If you have entered you're PIN incorrectly 3 times your SIM card will be blocked and you will be unable to make and receive calls/texts. To unblock your handset, you will need to obtain the PUK code from your Network/Service Provider.
|
|
Polyphonic comes from the word polyphony, meaning "many sounds". It refers to music that has many notes sounding together, either in a chordal, or countrapuntal setting. Polyphonic ring tones vary in specification from phone to phone, but all polyphonic phones support the playing of more than one note together, so your ring tone is generally more musical.
|
| Portability (Mobile Number) |
|
Mobile Number Portability (MNP) is the ability to retain a mobile number when moving or porting from one mobile carrier to another. MNP occurs when the mobile network is different and mobile number is the same. This process is also sometimes called migrating or transferring. To begin the process, contact your current Service Provider (the company your contract is with) and ask for a Porting Authorisation Code (PAC). The PAC is your authority to request a transfer and will allow the Network you wish to move to, to request your number be transferred to them. However the PAC is only valid for 30 calendar days so you must action your request promptly.

Usually used as a marketing term to described a web site that is or is intended to be the first place people see when using the web. Typically, a portal site has a catalog of web sites, a search engine, or both. A portal site also may offer e-mail and other service to entice people to use that site as their main "point of entry" (hence "portal" to the web). Most networks offer their own WAP portal which can be accessed via a WAP-enabled handset. |
| Predictive Text Messaging |
|
Predictive text messaging is a facility built into many mobile phones that allows the phone to 'guess' the word you are trying to type. Predictive text messaging saves you having to press your mobile phone keys several times over to get the letters and words you want. Instead you just press the keys once and then go on to the next letter. Your mobile phone will then fill in (or predict) the word you are typing.

SIM Free refers to GSM phones that are sold without a connection or line. SIM Free phones can be locked to any particular network and therefore they may not accept any SIM inserted. A tri-band SIM Free phone will work on any GSM network in the world, but you must insert a SIM that works in the area that you want to use it.
All GSM 900 / GSM 1800 compatible SIM Free phones will work on any UK SIM.
|
|
A SIM Lock code is a code which prevents your phone being used on other mobile networks in that it will not accept SIM cards from other networks. If your phone is bought with a pay monthly agreement or pay as you go, then your phone is likely to be SIM locked to that network. You can get the unlock code by contacting the network operator that you signed up with. The network operator may charge you a fee for this if you have not fulfilled your agreement.

Some camera phones have a zoom facility which you can use to bring an object closer rather than you moving closer to it. There are two types of zoom you should be aware of. A digital zoom will take each pixel that the camera sees and stretch it so that it appears larger. Doing this will reduce the overall picture quality and the more you do this, the more blocky the picture will appear. An optical zoom uses lenses to enlarge the image. This allows you to get closer to take a picture of the subject without reducing the quality.
