What is an Access Point (AP)?

Acronyms

What does MIMO stand for?

What is ADSL?

What is QoS?

What is WISH?

What is WPS?

What is DCC?

This particular wireless technology (also referred to as " Wi-Fi ") allows radio communication between computers so they form a network. With the addition of a router, all can share a broadband Internet connection.

A 3x3 antenna design currently represents the best cost/performance ratio. Past that value of 3, the soaring cost involved does not justify the small increase in performance. As costs gradually go down, it will be more viable to include more antennas.

Wireless communications take place over the air, so anyone with a proper receiver can listen in, making this medium very unsecure. This is why encryption is important: it will prevent outsiders from tapping into your broadband connection without your knowledge and, furthermore, will protect your data from being stolen.

Scientific research has only recently begun in this area, so there is no definite answer yet. However, one study conducted between 2003-2005 about mobile phones concluded that "No evidence was found to indicate that people with self-reported sensitivity to mobile phone signals are able to detect such signals " (British Medical Journal, March 2006). Since Wi-Fi equipment emits less intense radiation than do mobile phones, this supports the argument that wi-fi radiations are in fact harmless.

"Draft" means that some details have not been finalised, and are still in discussion. This is a normal process that takes a long time to complete. Final completion of the standard is expected in early 2008. However, we know since version 2 of the draft that all products will be software-upgradable.

D-Link uses chipsets from three major providers in its range, ensuring the best level of compatibility compared with competitors.

Of course! With QoS and sophisticated wireless encryption, you get many business-class features. Only the missing official Wi-Fi stamp prevents us from marketing this range at business users.

A router is the device that allows you to share your broadband connection between several computers.

An Access Point is used for wireless connections, linking devices together wirelessly.

Multiple In, Multiple Out refers to the use of multiple antennae at both the transmitter and receiver sides, in order to increase throughput and signal reliability. It is the cornerstone of 802.11n technology.

Asymmetric Digital Subscriber Line: a broadband technology that uses the traditional telephone lines for transporting data.

Quality of Service: a mechanism that gives priority to delay-sensitive data, eg gaming will be given priority over e-mail, to eradicate lagging. With StreamEngine, the process is automatic.

Wireless Intelligent Stream Handling: the wireless version of our StreamEngine. With StreamEngine, data going to and from the Internet is assigned priorities automatically, according to how sensitive it is to delay. With WISH, the same process is applied on data moving to and from the wireless network.

Wi-Fi Protected Setup: the Wi-Fi Alliance's standard for wireless security at the touch of a button. With WPS, the wireless network name (SSID) and encryption keys are automatically generated and broadcast to the client devices. Users do not have to memorise complicated passwords and key them in several times. This considerably simplifies the process of setting up security on the wireless network.

D-Link Click'n Connect: a software that runs directly from the product CD and in a few simple steps helps install and configure your device, with no technical knowledge required. With our bundle kits, the wizard even tells you when to insert your adapter!
