A network via socket.

House or apartment to network is "in" - but usually far too difficult. A wireless LAN must be configured for a cable network stripping drag. Simple it with Powerline adapters go. The advantage of the local power for local area networks, are usually easy to operate.
  PCs and other devices at home networking, is sometimes associated with hard work. The non-functioning automatic assignment of IP addresses is still the least of evils. Poor driver for a post-installed Wi-Fi card will not only lay people quickly to the Palm. Remedial promise the producers of so-called powerline adapters.
Another new product, and a manual, which you must durchackern are mainly consumer technikmüde say. Far from it: Powerline adapter, the networking in the home easier - and do it well. The idea behind it, data on the power line to send it there for decades.
Powerline adapter for home use are also not new. Meanwhile, the bandwidth to cope with adapters, including the transfer of movies in HD-quality permit. Moreover, the first devices with an easy to use encryption on the market.
Alternative for Ethernet and Wi-Fi
Requires at least two adapters. These have on the one hand, a standard connector for the outlet. On the other side is according to design an Ethernet interface or a USB port for connecting to a computer or another device that is inserted into the network will be. Powerline is an alternative to both Wi-Fi as well as wired Ethernet network.
Especially comfortable Powerline, because relatively few users, or depending on the model did not work must configuration. It is usually the adapter into the outlet to stöpseln and ordering the equipment - and the network stands. So far, however, were supported bandwidths not large, so that for example, the streaming videos are often not very smooth shape.
Digital television by Stromleitung
With the adapters in the current generation are now data rates of up to 200 megabits per second (Mbps) achieved gross. Is the net value, according to Christoph Rösseler by the manufacturer Devolo around 90 Mbit / s. The actual transmission speed may vary from household to household differ, which is much different in the nature of the electricity network is justified. Moreover, other grid connected devices such as refrigerators or washing machines, the quality of the transfer price.
The Internet provider Alice holds the transmission speed is high enough to meet its customers a discounted product to offer. Alice brings to its customers via DSL and television into the house. Now, the phone jack for the DSL connection in most cases right next to the TV. To the TV program yet elegant for the set-top box or the TV to get the adapter.
Beware of multiple sockets
Among the manufacturers of such products include Allnet, Devolo, D-Link, Linksys, Netgear and Siemens. Devolo dLAN 200 has the AVeasy in the program - consisting of two adapters. It allows the power supply for applications such as Internet TV in HD quality to use. The range is as specified by the manufacturer within a 200 meter circuit.
Without a hook is not Powerline: "It is not all as easy as it looks at first," says Peter Knaak from the Stiftung Warentest in Berlin. Apart from the fact that the electricity wiring in the house a significant impact on the bandwidth of the powerline network did, it was recommended that the adapter directly into the wall socket to plug. Even manufacturers such as Devolo disrecommend, the adapter into the multiple socket to plug an extension because of which the transfer could suffer.
The solution is Powerline adapter, which in turn have an outlet, so that the wall does not block it.
And the security?
When it comes to safety via Powerline transmitted data, some manufacturers have been so herausgeredet that own electricity a safe barrier to unauthorized access from some neighbors in the apartment building impossible. Meanwhile, experience has shown that under certain conditions an unwanted intrusion into the network adapter with an identical or with an adapter that supports the same standard, and thus a possible encryption makes sense.
The IT security of Powerline products based, according to Frank Sebastian by the Federal Office for Information Security (BSI) in Bonn usually proprietary solutions to the manufacturer. "For most products, each adapter a Security ID, by an adapter may be clearly identified." Over a bundled configuration software can be a network password for the encryption to be created. A part of the manufacturer offers at least in its current devices to an integrated encryption: In order to activate it, enough to a certain button on the adapter itself press.
Very cheap Powerline is not: A pair of Powerline adapter with a gross transfer rate of 200 Mbps is about 100 euro. Models with lower bandwidth is much cheaper. A pair of Powerline adapter with a gross transfer rate of 200 Mbps and integrated power cost from around 130 euros.
