FUNCTION AND FEATURE ACCESS POINT

FUNCTION.
Access Point serves as a regulator of the data traffic, allowing many clients to connect over a network (network).
as a Hub / Switch that acts to connect the local network with a wireless network / wireless, the access point is a data connection / internet emitted or transmitted via radio waves, measure the signal strength also affect the coverage area will be reached, the greater the signal strength (in units of measure dBm or mW) the more far-reaching.

FEATURE ACCESS POINT
 A. Multifunction Modes
A good wireless access point is able to work or operate in different operating modes: as an Access Point, Repeater, Bridge and Wireless Client. As a wireless access point (WAP), this device could allow the network LAN cable developed a wireless network by connecting to an AP is one of your LAN network port Ethernet Switch kesebuah eg to a modem or router directly.
The following figure is an example diagram of several operating modes AP

As the wireless bridge or wireless client, enabling the device with an Ethernet port to connect to your wireless network. With a wireless bridge you can connect a LAN to another LAN network through wireless connections between buildings for example. Or some network devices such as desktop computers, printers, notebooks, which are connected to a switch and connect the wireless bridge to connect to your wireless network.
While the wireless repeater, you can add AP to expand your wireless network without having to connect to the wired backbone network.



2. Support WDS
Best wireless access point must support the features Wireless Distribution System (WDS). With a WDS wireless network can be developed using a wireless AP without having to use a cable backbone network and wireless client roaming between APs can. With WDS feature is you can develop a large wireless network with each link between the wireless AP with WDS links without having to be connected to the backbone network cables as well as traditional AP. Generally WDS feature is very suitable for use on a wireless network environment is vast and wide such as in factories, on campus and so on.

3. Wireless N
Wireless access point would be the best in the stretcher with the latest wireless technology 802.11n wireless standards the final version. We know that the draft version of 802.11n has been approved by the IEEE in September 2009 and then became the official 802.11n wireless standard with only a few additional options from its draft version. Combined with MIMO smart antenna technology, the 802.11n wireless standard provides a speed up to 300 Mbps ideally even more, and also a wider range.
If the wireless network you are using streaming video, gaming, or voice, it is better to use a wireless N dual-band versions (2.4 and 5 GHz).

4. Advanced Security Features
Best wireless access point must support the reliable security features including the latest wireless security features to support the industry standard Wireless Protected Access (WPA/WPA2), MAC address filter, SSID broadcast control. For use in environments jarngan corporations will need also need to advance security features (EAP-MD5, EAP-TLS, EAP-TTLS, and PEAP), and also if necessary, that will support RADIUS authentication if you have a network of corporations central RADIUS server. And also to facilitate the installation of client connections to the network also features needed to support Wireless Protected Setup (WPS), which is usually just press the push button for easy connection.
