1. An outdoor luminaire for suspended mounting from, or attached to, a line, the luminaire comprising:
a housing of the luminaire having
a first exit window for egress of illumination light and
a second exit window for ingress and egress of a radio communication signals;
mounting point attached to the housing for attaching the housing to the line;
a power input for providing power to the luminaire;
a levelling unit attached to the housing or to a member that is attached to the housing in a fixed manner, and to an antenna unit inside an interior cavity of the housing, the levelling unit configured to either passively, utilizing gravity, or actively, utilizing a rotational actuator, counter rotational movement of the luminaire along a rotational axis parallel to the line at the mounting point;
a first modulation unit for use as a communication node in a wireless data network connected to the antenna unit, the first modulation unit configured to generate a first modulation signal;
the antenna unit attached to the levelling unit, wherein the antenna unit comprises at least one antenna for:
emitting a first radio signal based on the first modulation signal through the second exit window along a radiation pattern having a main lobe, when the luminaire is level, in line with a plane orthogonal to the gravitational axis when the luminaire is mounted and
receiving a second radio signal through the second exit window; and
a lighting unit comprising one or more light sources for emitting illumination light through the first exit window.
