What is an Access Point? Unlike the Repeater and APN – simply explained

The term access point often arises in connection with WLAN and routers such as the Fritz box. We tell you in this guide, which is an access point, and what are the differences to the repeater and what APN (Access Point Name) smartphones means.

What is an Access Point?

An access point is building its own Wi-Fi at a different location and is connected to the router via LAN.An access point is building its own Wi-Fi at a different location and is connected to the router via LAN.

Access Point translates &Access point; # 8220&# 8221 ;. Exactly describes the function very clear: An access point allows other devices to log in via WLAN or LAN in a network and access as the Internet. The access point is connected via a LAN connection to the router. The WLAN Access Point case has a different SSID than the router.

A router like the Fritz box can be connected to another Fritz box as an access point. How to do this, we show here:

Difference: Repeater and Access Point

A repeater is connected to the router via Wi-Fi Bridge and amplifies the signal.A repeater is connected to the router via Wi-Fi Bridge and amplifies the signal.

(WLAN) repeater translates &Repeaters; # 8220&# 8221; or &# 8220; amplifier&# 8221 ;. A repeater links usually via wireless bridge to a router and enhance the existing wireless signal as in other areas of an apartment. Wireless repeater is available as a standalone solution. However, a Fritz box also can be set up as a repeater to another Fritz box:

Info: Since an access point is connected via a LAN cable to the router, the wireless connection and range of an access point usually faster and more stable than that of a repeater. In a repeater, one can assume that the data rate is halved as it takes time until it has passed the wireless signal to the router.

What is an APN?

The term comes from the APN Mobile area and means &# 8220; Access Point Name&# 8221 ;. He called an access point to a mobile network. A smartphone can thus register with the provider in the mobile data network via GPRS (also EDGE) or UMTS / 3G. Thus the APN defined, to which the access point and thus to which network a connection for a mobile terminal to be established. Whether you use a device with Android, iOS or BlackBerry, it does not matter.

When setting up a GPRS or UMTS connection, the phone informs the SGSN (Serving GPRS Support Node) to the APN. This then determines through a DNS query in the GPRS backbone network the registered for this APN competent GGSN. Thereafter establishes a GTP connection between SGSN and GGSN, via which the data packets are transported from the smartphone to the access point and from there to the packet data network.

The access point name can be in the settings under Android under &Wireless; # 8220 & networks&# 8221; > More&# 8230; > mobile networks > view and edit access points (APN). In general, the access points are automatically set but with the use of the SIM card of the provider.
