Four parts of the five-part Harmonised Standard for UWB
were completed in 2016; good progress was made with the
final part, on UWB on board aircraft. In August we published
the third part of a multipart TR on UWB signal characteristics,
describing the various UWB regulations in place in different
parts of the world.

Work progressed well with two new SRdocs, on UWB in
medical applications and on amended mitigation techniques
for UWB. Work on an SRdoc on UWB-based vehicular access
systems was completed in June.

Satellite Communications
Satellite technology is an important delivery platform for
diverse services such as direct-to-home TV and mobile, high-
speed Internet access and location services. It is particularly
useful for rural and outlying regions, where it is difficult to
deploy other systems on a commercial basis, and therefore
plays a key role in ensuring that all European citizens are able
to access high quality information services.
