Problems solved by technology

Although the cost of this solution may be less, the method of passively interconnecting devices leads to increased attenuation between nodes due to the use of various transmission devices in parallel, to the detriment of connections that already have significant attenuation themselves
Furthermore, the noisiest unit will limit the dynamic margin of the cleanest unit by increasing its noise level or noise floor
[0009] Another limitation is that the PSD (Power Spectral Density) cannot be adjusted for each device, and the power delivered from one device to another depends on factors beyond the control of a human
This would require injecting the minimum allowable power in the most constrained device, thus disadvantaging devices where more power could be injected

Embodiment Construction

[0026] In the case of a network via in-house wiring, the transmission device may be one of the following:

[0027] ●PLC (“Power Line System”)

[0028] ●Telephone line

[0029] ●Coaxial cable

[0030] ●CAT5 cable, etc. (Ethernet type)

[0031] According to the invention, the device interconnecting the devices consists of a single node (rather than one node for each transmitting device) with a single multi-device network (domain) (where there is not the same number of networks as devices) ( image 3 and Figure 4 ). This node is connected to different devices with separate AFE (Analog Front End) for each device. Since this node is a single node, there is only one AMP (Access Device Plan). And all devices operate jointly at the access device level. Each configuration in the AFE is used to inject signals into the specific device it is connected to, and is consistent with the power spectral density (PSD) mask allowed in each device.

Abstract

The invention relates to a communication node and a procedure for various means of transmission. A node and a procedure are configured for their use in a data signal communication system through N different means of transmission. The node comprises N independent AFEs. Each AFE is configured to receive or transmit the signal on a corresponding means of the N different means of transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Spanish patent application ES201030411 filed on March 22, 2010. The entire disclosure of the above application is hereby incorporated by reference. technical field [0003] The present invention is applied to communication systems using various transmission devices. In particular, the nodes and procedures of the present invention allow a node of a communication network to be simultaneously connected to various communication devices and to communicate with a node connected to any one of the communication devices. Background technique [0004] For the purpose of improving the coverage of a communication network, various transmission means (electrical, coaxial and telephone cables, or wiring) are available which are connected to each other to implement a common communication network. [0005] For this purpose hitherto known systems use different nodes for each device and switch bet...
