Sneezing realm of Gardena
Ingeniously: LAN connection over conventional water pipelines
Otherwise rather for garden devices well-known manufacturers Gardena revolutionary sneezing realms succeeded.
The speech is from a hardware adapter, which makes a LAN connection over convententional water pipelines.
The principle is very easy: The adapter is attached to a tap and the cock is untwisted, so that a water connection is created.
But no concern, in the adapter is a water stopper, which prevents the discharge.
The network signal is then modulated by particularly developed electronics by means of inductive stray voltage over a phase electric rectifier on the water pipeline.
With spurious frequencies one does not have to fight here, since a water pipeline is free from frequencies and the waterpipelines serve as good isolation, then is reported it from intern circles.
Depending upon adjusted water temperature data transmission rates in the Gigabit range can apparent be obtained.
First prototypes are already finished and successful in the test.
Series production is to follow soon! We remain times strained, whether that will become generally accepted;)!
