Alcatel demonstrated Europe’s first broadcast of live TV channels on mobile handsets in S-band. The demonstration used the new DVB-SH
standard (Satellite services for Handhelds), which is currently being
drafted by the DVB Project. To perform this demonstration, Alcatel was assisted by UK broadcasters Sky, ITV and BBC.
DVB-SH is a new technology targeting the S-band. DVB-SH is a
related standard to DVB-H. With DVB-SH technology, Mobile TV signals can be broadcast from satellites as well as from terrestrial transmitters directly to handhelds.
The demonstration featured SAGEM myMobileTV handsets using the S-band telecom frequency between 2.17GHz and 2.20GHz, which is adjacent to the 3G/UMTS band. 30MHz of spectrum is currently available all across Europe and in other major regions in the world.
In addition, Alcatel demonstrated two possible key technical features using the DVB-SH standard. Reception Antenna Diversity, a feature using two antennas inside the same mobile device, enables improvements in the signal quality under difficult conditions. Furthermore, improved Time Interleaving overcomes fading impairment in mobility conditions. The significant quality enhancement was demonstrated by implementing these DVB-SH features.

- In October 2006, SES GLOBAL and Eutelsat Communications announced a 50/50 joint venture company, which will operate and commercialize S-band satellite services over Europe for mobile video services. The S-band (2.0 and 2.2 GHz), which represents a new frequency band for both SES and Eutelsat, provides a set of frequencies optimized for supporting a wireless distribution network for mobile devices, including phones, PDAs, laptops and vehicle receivers.
Eutelsat Communications confirmed its order with Alcatel Alenia Space for an S-Band payload on its upcoming W2A satellite, which is slated for launch in 2009. Based on the Alcatel Alenia Space Spacebus 4000C4 platform, W2A’s missions also comprise up to 46 transponders in Ku-band and a C-band payload of 10 transponders.
