Testing a cable

A test device for testing a cable connectable to a remote radio head of a plurality of remote radio heads connectable to a same radio base station of a wireless communication network, the test device comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, causes the test device to:
• generate an outbound test container, the outbound test container comprising digital samples representing a test signal;
• transmit the outbound test container and a frequency parameter, indicating a frequency on which the test signal is to be transmitted, to a converter device being connectable to the plurality of remote radio heads connectable to the same radio base station via respective cables, for transmission by the converter device;
• receive an inbound test container, the inbound test container comprising digital samples of a response signal received by the converter device based on the outbound test container;
• and
• evaluate the inbound test container,
• wherein the test device is a separate device from the converter device, and
• wherein each of the plurality of remote radio heads is configured to transmit wireless signals to a user equipment as part of a single radio cell of the wireless communication network.

A test device comprising:

• means for generating an outbound test container, the outbound test container comprising digital samples representing a test signal;
• means for transmitting the outbound test container and a frequency parameter, indicating a frequency on which the test signal is to be transmitted, to a converter device being connectable to a plurality of remote radio heads connectable to the same radio base station via respective cables, for transmission by the converter device;
• means for receiving an inbound test container, the inbound test container comprising digital samples of a response signal received by the converter device based on the outbound test container;
• and
• means for evaluating the inbound test container,
• wherein the test device is a separate device from the converter device, and
• wherein each of the plurality of remote radio heads is configured to transmit wireless signals to a user equipment as part of a single radio cell of the wireless communication network.

A non-transitory computer readable medium which contains a computer program for testing a cable connectable to a remote radio head of a plurality of remote radio heads connectable to a same radio base station, by a test device which, when run on the test device causes the test device to:

• generate an outbound test container, the outbound test container comprising digital samples representing a test signal;
• transmit the outbound test container and a frequency parameter, indicating a frequency on which the test signal is to be transmitted, to a converter device being connectable to the plurality of remote radio heads connectable to the same radio base station via respective cables, for transmission by the converter device;
• receive an inbound test container, the inbound test container comprising digital samples of a response signal received by the converter device based on the outbound test container;
• and
• evaluate the inbound test container,
• wherein the test device is a separate device from the converter device, and
• wherein the remote radio head is configured to transmit wireless signals to a user equipment as part of a single radio cell of the wireless communication network.

A method for enabling testing of a cable connected to a converter device, the cable being connectable to a remote radio head of a plurality of remote radio heads connectable to a same radio base station, the method being performed in the converter device and comprising the steps of:

• receiving an outbound test container and a frequency parameter from a test device, the outbound test container comprising digital samples representing a test signal, wherein the frequency parameter indicates a frequency on which the test signal is to be transmitted;
• converting the digital samples of the outbound test container to an analogue test signal on the frequency indicated by the frequency parameter;
• transmitting the analogue test signal on a cable connected to the converter device;
• receiving an analogue response signal from a cable connected to the converter device;
• generating an inbound test container comprising digital samples of the analogue response signal;
• and
• transmitting the inbound test container to the test device,
• wherein the test device is a separate device from the converter device, and
• wherein the remote radio head is configured to transmit wireless signals to a user equipment as part of a single radio cell of the wireless communication network.
