Powerline / DLAN
Powerline networks (also called DLAN) are implemented using power cabling within an object. The advantage here is that there is no need for complex network cabling / data cabling, but rather the normal power grid within a house or apartment. The DLAN adapters are simply plugged into a free socket. After the adapters have been "paired" with one another and have negotiated a common encryption (this prevents someone from simply gaining access to an existing network with a DLAN adapter), the adapters can now transmit data to one another.
On the underside of the DLAN adapter there is then one or more RJ-45 sockets to which a normal Ethernet cable can be connected. You can connect any number of end devices to one another via a DLAN network. Your internet router can of course also be integrated. All connected devices can then use the router's Internet connection.
Very high transmission rates (up to 1200 Mbps) are now possible. There are also modules that can send a WiFi signal so that devices can also be integrated into the DLAN network via a wireless connection. A prerequisite for a DLAN is that the sockets used are on the same phase.
It almost sounds like a dream: Internet in the whole house - without connection problems, without security issues and above all without annoying cables. DLAN a quite new technology that simply sends the data packages via the existing power cables via a power outlet. In principle, the two adapters are simply plugged into a free socket and you're ready to go. DLAN can be used both as part of a ethernet network, for example to overcome distances over floors, or as part of a WiFi network, e.g. the router can not be optimally placed. Via a network cable, the signal then reaches the first DLAN adapter, which sends it via the power network to the second adapter. This can then initiate a WiFi network.
Who is DLAN suitable for?
In principle, DLAN can be used in any household or building, if a few conditions are met. For example, it must of course be a closed power grid, so that the data can also reach the desired destination. But then virtually any socket of this network serves as its own Internet connection and can be used as well. Of course, an existing outlet in the respective rooms is also an important prerequisite.
Who lives in a small apartment, has not placed unfavorably placed or massively built walls or other disruptive factors and also on good hardware, should not have a problem with range or signal aborts in the use of Wi-Fi and does not need a DLAN network in principle. But even in this constellation and living situation, some people want a wired network, e.g. for privacy and security reasons. If you do not want to open walls, or if you want to make a crash-prone clutter of cables on the ground, you can simply bridge the distance between the rooms via the DLAN adapters and connect LAN cables to them. The possibilities are manifold. By the way: DLAN is also a great alternative even with very trivial range problems of the WiFi network: Via the DLAN network the data can be sent up to 300 meters!
How does DLAN work?
Simply put, the power line serves as a carrier for the data signals. The adapters in the socket modulate the signals so that they can be transported via the power line. In the power grid, they are perceived as tiny disturbances, but they are easily in the designated tolerance range and thus have no impact on the flow of electricity. For the user, when using DLAN, there is no difference to using other technologies such as ethernet or WiFi. Handling DLAN is therefore as simple as with these. Also, the setup and configuration of the socket adapter is done quickly. Settings for security and personalization can be made via an easy-to-use user interface. Then it can start.
Is DLAN right for me?
Depending on which structural conditions one finds in a building, different technologies must be used, if necessary also in combination. Thus, a router with sufficient space for an apartment provides sufficient range, with disruptive factors would have the same model, a high-performance WiFi antenna, a wireless amplifier or a wireless repeater can be switched on, if a stable Internet connection should be guaranteed. Although this problem does not arise with a ethernet connection, most cables would usually have to be laid, resulting in high costs and costs. Although popular powerline components are already available at very reasonable prices, you have to accept some disadvantages in terms of speed when transferring data. However, high-quality models are as fast and reliable as WLAN and thus a good investment in the future, above all because data security is high and hackers are barely able to penetrate the power grid. However, malicious software from the end devices can not stop DLAN either, which is why good firewall protection should also be provided with this technology.
