May's a bit more radio be?.

Walls and ceilings are designed for wireless networks often insurmountable obstacles. Those who still want to surf on the top floor, is equipped with a Wi-Fi repeater happy. The devices amplify the radio signal - in series, they can provide whole streets.
  Daniel Frenzel has a problem: The apartment of 23-year old student, an old building in downtown Fürther runs over two floors. In the bottom, next to the door, there are telephone and wireless router. But Frenzel would also like to the first floor from the bed to surf. And no matter where the student is in his bedroom - anywhere his laptop shows "no wireless connection" to.
Also, the landlord can not do anything. His lapidary statement: Stark screen the buildings. Thick walls and ceilings, lots of steel and iron in water pipes or cables, and - what exactly the Radio-stop care can not be ascertained. One, however, was clear: In Daniel Frenzels bedroom, it will be for the foreseeable future, no internet.

Conventional DSL Router with Wi-Fi wireless technology, depending on the nature of walls and ceilings only several meters wide. If you want to enlarge the home network, however, can a technique to fall back, currently at home users is growing in popularity: For several months, for example, offers Internet provider 1 & 1 "in addition to his new FRITZ! Box a so-called" Wi-Fi repeater. For 49.99 euros, even inexperienced users will be "with only a few simple" expand its network and also in remote corners of the apartment can direct.
While Wi-Fi repeater has been a niche product for private users, not new is the W-LAN extension, however, not the former Siemens subsidiary Gigaset produced Wi-Fi repeater for five years. AVM presented competitors this year. By FRITZ! WLAN Repeater manufacturer is an improvement in the Wi-Fi range for each user, easy: "The repeater can be connected to any electrical outlet used for a secure wireless connection reaches only a brief touch of the screen," says AVM Samira Jordan spokeswoman.
Repeater: No more than one data-passing
The functioning of the Wi-Fi repeater is explained with a sentence: The unit reinforces the Wi-Fi signals so that in theory, even the supply of entire streets with W-LAN is possible and feasible. This is made possible by a technology often called "Wireless Distribution System (WDS). Here, the repeater at the range limit of the Wi-Fi router positioned to receive the signals, amplifies it and sends it again. Even neighbors could be the signal with any Wi-Fi-enabled computers receive and thus share the DSL connection.
Most buyers repeater set the device but not for the local Wi-Fi-socialism, but also to its network in remote corners of your own home use. An example: "The access point is located near the entrance and the computer in the house diagonally opposite to the upper floors. If a repeater vertically above the access point installed in the next floor, sends and receives the signals from the repeater then" horizontally on the floor, "says Christopher Volk, product manager at Gigaset Broadband Communications. Even if the Wi-Fi in other buildings on your own land, for example, in the garage, or with neighbors will be used, makes the use of a repeater sense.
To the network amplifier into operation, there are no professional skills necessary: "The repeater supports the upcoming Wi-Fi N standard, but also standard 802.11g, b or a," says spokeswoman AVM Samira Jordan. The repeater can transmit data in the 2.4 - or 5-GHz band transferred. This allows many users with Wi-Fi wireless networks, in the neighborhood to the less-used 5-gigahertz Frequenband dodge. The integrated multi-antenna methods MIMO (Multiple Input Multiple Output) is also a very good coverage and higher data rates.
W-LAN ENLARGEMENT: THE SOLUTION FOR HÄRTEFÄLLEEine further option, a Wi-Fi to expand the building if the harder is the bridge with the aid of a power line connection. Manufacturers such as Netgear adapter to offer the Internet with a connection on the power grid possible. For exotic cases, there is Power Line-W-LAN adapter, the Internet signal within the first circuit on the transport and power lines in the target area then a W-LAN network. The Powerline-hybrid solution is useful if the pure radio solution despite not gain enough: As long as DSL / router and Powerline Empfänger/W- LAN Extender other within one on a common security protection secured grid connected, does the thing - no matter how thick the walls are. Near Prone is about to guests with a LAN party via W-LAN, or to allow family members with a preference for laptops only. Otherwise, the direct path from DSL to the computer via Powerline significantly naheliegender.Netgear adapter calls this a "Wireless Range!
Extender" - an established, alternative term for the text addressed in Wi-Fi repeater. A package of Powerline adapter, which is directly connected to the DSL router or a tin can connect, and an extender will cost around 100 euros. Pure Repeater/Extender- solutions from other manufacturers, as Wi-Fi signal amplifiers are used, are 50 to 120 euros haben.pat
An unlimited Wi-Fi expansion is equipped with a repeater, however, not in it: "Under ideal conditions, is almost a doubling of the Wi-Fi coverage," says spokeswoman AVM Samira Jordan. Wi-Fi repeater can be connected in series in order to send a signal over a number of repeater stations, mainly in one direction to extend. "You can also star-arranged to ensure greater coverage in the area to ensure" says Christopher Volk, production manager at Gigaset Broadband Communications. It may be 4-6 Gigaset Repeater together, with series connection halved, however, the flow rate of repeater to repeater. "At the end of the chain is still possible, Internet access, transfer of videos, however, may be limited," warns the people.
