Almost every Internet provider provides its customer with online connection a WLAN-enabled router. Depending on how long you contract with the provider, you get the device even free. Hardly a user wants to renounce the comfortable wireless connection to the Internet at home. Apart from this, more and more networkable devices are found in the trade, which can only be integrated via WLAN into the home network. This includes, among other things, all modern smartphones, tablets, e-book readers, numerous web radios and wireless IP cameras. Smaller, more accustomed devices can often use WLAN only with very good reception conditions. In the mobile devices, the WLAN antennas are usually less effective than the much larger notebooks.
Receiving problems
Smartphone and tablet users depend on stable WLAN reception as they often change their location. Who wants to go with his mobile device from the kitchen into the living room to quickly look up a cooking recipe online, because in the kitchen the WLAN reception is too weak? The same applies to downloading music, retrieving movies, or updating the installed app. Even if the mobile device also has UMTS reception, bandwidth-intensive downloads are better handled via wireless LAN. In contrast to most UMTS tariffs, these connections are not limited to a certain transmission volume. The problem: WLAN can not be replaced easily by the alternative transmission types, such as network cable or the Powerline technology. Neither smartphones nor tablets have a network cable connection.
WLAN-n instead of WLAN-g
And who wants to hang his pretty, mobile little one already on an ugly, bulky LAN cable? So how can you improve the WLAN reception in your own house or apartment so that mobile devices can be used in all rooms?
Extensions by radio and power
The first step leads directly to the WLAN router. Here you should first check which WLAN standard the device supports. If it is a WLAN router according to the 802.11g standard, this transmits with a maximum transmission rate of 54 MBit / s. Although still many current devices are equipped with WLAN g adapters, this standard is already out of date. It is gradually being replaced by the much improved 802.11n standard (WLAN-n). WLAN-n offers significantly higher transmission rates depending on the hardware used, 150, 300 or even 450 MBit / s. The n-standard also uses various intelligent transmission techniques which can be used to bridge even unfavorable connecting distances. The first step for a better wireless network is thus: Replace the old WLAN-g router with a WLAN-n-pendant. For the exchange the access data for the Internet connection are necessary. In addition, one should consider a WLAN-n-Router with integrated modem and do not have an additional device. If the new router is set up, all WLAN devices at home must be reconnected to the WLAN of the new router. At certain distances or when several radio barriers, such as walls or floor ceilings, a WLAN-n router quickly reaches the limit of its range. Thus, a connection from the WLAN router in the basement to the notebook or web radio in another floor must overcome at least two storeys and possibly one or two walls. Depending on the structural conditions, connection problems may occur.
Powerline with access point
In such a case, a so-called WLAN repeater can be used. These devices extend the wireless network of a WLAN router. To do this, you place the repeater approximately halfway between the WLAN router and the terminal. In the example mentioned, this would be the ground floor, which is located halfway between basement and first floor. The repeater then establishes as a conventional WLAN client a connection to the WLAN router. The WLAN client on the first floor in turn connects to the WLAN repeater on the ground floor. In this way, the repeater routes all the data from the WLAN router in the basement to the device on the first floor and vice versa. Another way to bring WLAN reception into badly accessible rooms is a powerline adapter with integrated WLAN. The network connection is distributed by the router over the power supply. For this purpose, a LAN port on the router must first be connected to a conventional Powerline adapter, which in turn is plugged into a socket near the router. The second Powerline adapter is equipped with a WLAN access point and to any outlet Within the apartment or the house. After switching on, the connection to the Powerline adapter 1 and thus to the router is established. Any WLAN device (such as smartphones or notebooks) that connects to the WLAN of the Powerline adapter 2 is then automatically connected to the router via the power supply and the adapter 1.
Also here it is possible to take the WLAN Powerline adapter always in the desired room. Similar to the repeater, it is important that the connection of the two Powerline adapters via the power supply is stable enough. Which sockets-combinations work for the data transmission depends very much on the individual power cabling in the home or in the house.
An interesting alternative to the WLAN repeater is the Powerline adapter with an integrated access point. As a rule, such devices are offered as kits with a Powerline adapter for the connection to the router. While a WLAN repeater connects to the router via WLAN, The Powerline adapter connects to the router via the power cable installed in the house or in the apartment. The second Powerline adapter included in the kit is connected to a network port (LAN port) of the router and plugged into a free socket as far as possible Near the router. The connection between the conventional Powerline adapter and the router is done via network cable. In the second step, the Powerline adapter with WLAN option is plugged into a socket in the home or in the house. It connects via the power supply to the router and establishes a WLAN connection. The Powerline adapter makes an encrypted WLAN connection with the terminal easily with WPS at the touch of a button.
The devolo dLAN 200 AV Wireless N is an example. In addition to the integrated WLAN access point, the device also offers three Ethernet ports for connecting other devices via network cable. This makes it possible to connect network-capable Blu-ray players, media players, game consoles, TVs, printers or network hard disks to the home network (router) over the power network
A wireless network access is highly convenient as long as it is distributed throughout the household. However, every house or apartment situation is a little different and so depending on the constructional circumstances, there are always places that the wireless network of the wireless router simply does not reach or where it is much too weak.Here can be a WLAN or radio- Repeaters help: The device bridges unfavorable connection distances and thus ensures a largely stable supply even in places with poor connection. The practical feature of WLAN repeaters: The position is flexible and can be connected in principle to any socket in the house or in the home. It is important, however, that the repeater itself can always establish a sufficiently stable connection to the WLAN router. Once the device has been configured, it can be used in other places in the household as required. A repeater must be plugged into any outlet at half-way to the power supply. Afterwards, you set up a WLAN connection between the repeater and the router by setup wizard. The repeater behaves like a conventional wireless device against the router. With its second wireless module, the repeater then - similar to the WLAN router - stretches its own WLAN network. It offers all receivers within range a stable access to the home network and access to the Internet via the router.
In many households there are routers with the outdated WLAN-g standard and a maximum transmission rate of 54 MBit / s. If you want to improve the range and transmission power of your WLAN, this router should replace it with a current WLAN-n (802.11n). This is the currently most powerful WLAN standard, with transmission rates of 150, 300 or 450 MBit / s reached. The rates depend on the number of integrated transmit and receive antennas. However, the maximum values given here can only be achieved if the connected terminal supports WLAN-n.
Routers with WLAN-n use several transmit and receive antennas and transmit data on several parallel radio channels. This is referred to as "multiple input / multiple output" or "multiple data input / multiple data output" (MIMO). Intelligent antenna technology from WLAN-n can also send and receive data in a time-delayed manner. This way, even the signals that reflect on walls or obstacles can be exploited. The practice shows that most WLAN-n-capable routers also contribute to an improvement in the range even if the connected WLAN client is only equipped with a WLAN-g adapter. Nevertheless, a WLAN-n-router can not cause miracles. Some connections can not be bridged by a powerful WLAN-n device due to their length or specific radio barriers.
