Embodiment Construction

[0233] In the following, mutually comparable, similar or equivalent structural and / or functional elements will be denoted by the same reference numerals. The detailed descriptions will not be repeated in all instances in which they appear.

[0234] Fig. 1 is a schematic block diagram illustrating a possible structure of a communication environment 100 to which an embodiment of the power line communication method of the present invention can be applied. The communication environment 100 may be referred to as a global network of devices that may interact with each other through one device or another.

[0235] The communication environment 100 shown in FIG. 1 includes: a first power line communication system P located in a first room of an apartment 1; The room is in a spatially separated second room.

[0236] The first power line communication system P comprises three power line communication partner devices P1 , P7 and P10 in the example shown in FIG. 1 . Between the power l...

Abstract

A power line communication method is provided for realizing data communication between at least one first or sending power line communication partner device (P1) and at least one second or receiving power line communication partner device (P10). The inventive method comprises a step of checking transmission conditions of a plurality of possible communication channels (Ch1, ..., Chn). Thereby generating transmission condition data which are descriptive for the communication conditions of the respective possible communication channels (Ch1, ..., Chn). Additionally, a step of selecting communication conditions of the plurality of possible communication channels (Ch1, ..., Chn) as actual communication conditions based on said transmission condition data.

Description

technical field [0001] The invention relates to a power line communication method and equipment. [0002] More specifically, the present invention relates to a power line communication method for enabling data transmission or data communication between at least one first or sending power line communication partner device and at least one second or receiving power line communication partner device. More specifically, the present invention relates to a dynamic frequency domain or FD coexistence method for a power line communication system and / or to a dynamic time domain or TD coexistence method for a power line communication system. Background technique [0003] Although wireless communication technologies have become increasingly important in recent years, power line communication networks and power line communication systems are still valuable, and they participate in certain technological strategies. However, achieving a high degree of reliability remains a major task in t...
