| 3G | 3rd generation mobile communications. A digital system for mobile communications which aims at global use and provides increased bandwidth. 3G lets a mobile device user access a wide variety of services, such as multimedia. |
| Ad-hoc operating mode | A WLAN network mode where two or more devices connect to each other using WLAN directly without a WLAN access point. |
| Cookies | Cookies are little pieces of information, given by the server to you, to store information about your visits to a web site. When you accept cookies, the server is able to evaluate your use of the web site, what you are interested in, what you want to read, and so on. |
| DNS | Domain name service. An internet service that translates domain names such as www.nokia.com into IP addresses such as 192.100.124.195. Domain names are easier to remember but this translation is needed because the internet is based on IP addresses. |
| DTMF tones | Dual-tone multifrequency tones. The DTMF system is used by touch-tone telephones. DTMF assigns a specific frequency, or tone, to each key so that it can easily be identified by a microprocessor. DTMF tones allow you to communicate with voice mailboxes, computerised telephony systems, and so on. |
| EAP | Extensible authentication protocol. EAP plug-ins are used in wireless networks to authenticate wireless devices and authentication servers. |
| EGPRS | Enhanced GPRS. EGPRS is similar to GPRS, but it enables faster connection. For availability and data transfer speed, contact your service provider. |
| GPRS | General packet radio service. GPRS enables wireless access for mobile phones to data networks (network service). GPRS uses packet data technology where information is sent in short bursts of data over the mobile network. The benefit of sending data in packets is that the network is occupied only when sending or receiving data. As GPRS uses the network efficiently, it allows for quick data connection setup and fast data transmission speeds. You must subscribe to the GPRS service. For availability and subscription to GPRS, contact your service provider. During a voice call, you cannot establish a GPRS connection, and any existing GPRS connection is put on hold unless the network supports dual transfer mode. |
| GPS | Global positioning system. GPS is a worldwide radio navigation system. |
| HTTP | Hypertext transfer protocol. A document transfer protocol used in the web. |
| HTTPS | HTTP over a secure connection. |
| IMAP4 | Internet mail access protocol, version 4. A protocol used for accessing your remote mailbox. |
| Internet access point | An access point is where your device connects to a network. To use e-mail and multimedia services or to connect to the internet and browse web pages, you must first define internet access points for these services. |
| Infrastructure operating mode | A WLAN network mode where devices are connected to WLAN using a WLAN access point. |
| PIN | Personal identity number. The PIN code protects your device from unauthorised use. The PIN code is supplied with the SIM card. If the PIN code request is selected, the code is required each time the device is switched on. The PIN code must be 4 to 8 digits long. |
| PIN2 | The PIN2 code is supplied with some SIM cards. The PIN2 code is required to access certain functions supported by the SIM card. The length of the PIN2 code is 4 to 8 digits. |
| POP3 | Post office protocol, version 3. A common mail protocol that can be used for accessing your remote mailbox. |
| PUK and PUK2 | Personal Unblocking Key. PUK and PUK2 codes are required to change a blocked PIN code or PIN2 code, respectively. The length of the code is 8 digits. |
| SIP | Session Initiation Protocol. SIP is used for creating, modifying, and terminating certain types of communication sessions with one or more participants. |
| SSID | Service set identifier. SSID is the name that identifies the specific WLAN. |
| Streaming | Streaming audio and video files means playing them directly from the web without downloading them first to your device. |
| UMTS | Universal Mobile Telecommunications System. UMTS is a 3G mobile communication system. Besides voice and data, UMTS enables audio and video delivery to wireless devices. When you use your device in GSM and UMTS networks, multiple data connections can be active at the same time, and access points can share a data connection. In the UMTS network, data connections remain active during voice calls. You can, for example, browse the web faster than previously possible while simultaneously speaking on the phone. |
| UPIN | PIN code used in UMTS network. |
| UPUK | UPIN Unblocking Key. UPUK code is required to change a blocked UPIN code or PIN2 code. The length of the code is 8 digits. |
| USIM | SIM card used in UMTS network. |
| USSD command | A service request, such as request to activate an application or configure various settings remotely, that you can send to your operator or service provider with your device. |
| VPN | Virtual private network. VPN creates a secure connection to compatible corporate intranet and services, such as e-mail. |
| WAP | Wireless application protocol. WAP is an international standard for wireless communication. |
| WEP | Wired equivalent privacy. WEP is an encryption method that encrypts data before it is transmitted in WLAN. |
| WLAN | Wireless local area network. |
| WPA | Wi-Fi Protected Access. Security method for WLAN. |
| WPA2 | Wi-Fi Protected Access 2. Security method for WLAN. |
