METHODS AND NETWORK NODES FOR COMMUNICATION BETWEEN A FIRST NETWORK NODE AND A SECOND NETWORK NODE OVER A TWISTED PAIR WIRE

摘要

A first network node of a cellular system is configured for communication with a second network node over a twisted pair wire. The first network node includes a receiver for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also includes an up-converter for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal.

1. A method performed by a first network node of a cellular system for communication between the first network node and a second network node over a communication channel comprising a twisted pair wire, the method comprising:
receiving, over the communication channel comprising the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted by the second network node from a high frequency signal having a frequency higher than a frequency of the intermediate frequency signal; and converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal.
