## Abstract

Methods and systems are provided for designing, implementing, and/or using communication cables comprising a leaky feeder structure, which may be configurable for homogeneous distribution of data signals. An example communication cable may comprise a core conductor, an insulation shield surrounding the core conductor, an outer conductor around the insulation shield and having one or more apertures arranged along its length, and a jacket at least partly covering the outer conductor. The communication cable may also comprise an illumination arrangement which may be arranged at least along sections of the length of the cable. The illumination arrangement may comprise a plurality of light emitting units.

## Claims

### Claim 1

A communication cable configured to distribute data signals, the communication cable comprising:
a core conductor;
an insulation shield;
an outer conductor;
a jacket; and
an illumination arrangement, wherein the illumination arrangement comprises one or more of: emitting diodes, illuminated fiber tubes, illuminated fiber strips, plastic optical fibers, fluorescence units, lasers, or bulbs.

### Claim 2 (depends on 1)

The communication cable of claim 1, wherein the illumination arrangement is powered by at least one of the core conductor or the outer conductor.

### Claim 3 (depends on 1)

The communication cable of claim 1, wherein the illumination arrangement comprises one or more light units.

### Claim 4 (depends on 1)

The communication cable of claim 1, wherein the illumination arrangement is arranged radially inside the jacket.

### Claim 5 (depends on 1)

The communication cable of claim 1, wherein the jacket comprises one or more transparent areas or openings.

### Claim 6 (depends on 1)

The communication cable of claim 1, wherein:
the illumination arrangement comprises one or more light units arranged radially inside the insulation shield along the core conductor; and
the insulation shield and the jacket are transparent at least in regions of one or more apertures of the outer conductor.

### Claim 7 (depends on 6)

The communication cable of claim 6, wherein the core conductor is operable to power the one or more light units arranged radially inside the insulation shield.

### Claim 8 (depends on 1)

The communication cable of claim 1, wherein the illumination arrangement comprises one or more light units arranged between the jacket and the insulation shield.

### Claim 9 (depends on 8)

The communication cable of claim 8, wherein the outer conductor is operable to power the one or more light units arranged between the jacket and the insulation shield.

### Claim 10 (depends on 1)

The communication cable of claim 1, wherein the illumination arrangement is located on an outer surface of the jacket, and a second jacket is arranged over the illumination arrangement.

### Claim 11 (depends on 1)

The communication cable of claim 1, wherein the insulation shield comprises light guiding material.

### Claim 12 (depends on 1)

The communication cable of claim 1, wherein the communication cable is configured for distribution of radio data signals.

### Claim 13 (depends on 1)

The communication cable of claim 1, wherein the core conductor and the outer conductor are metal conductors.

### Claim 14

A communication cable configured at least to distribute data signals, the communication cable comprising:
a core conductor;
an insulation shield;
an outer conductor;
a jacket; and
an illumination arrangement, wherein the illumination arrangement comprises one or more of: emitting diodes, illuminated fiber tubes, illuminated fiber strips, plastic optical fibers, fluorescence units, lasers, or bulbs.
