.com/ Making Telecoms Work Philips and DiBcom known as Television Mobile Sans Limite14 (Mobile Television without Limits) to promote wider adoption of the DVB SH standard. China have several parallel standards initiatives using satellite and terrestrial interactive infrastructure and other localised reinterpretations of the T DMB and DMB T standards. 16.34 Eutelsat and SES ASTRA GSO - 'Free' S Band Payloads Eutelsat¹ has twenty three geostationary satellites. SES Astra¹6 has 36 satellites in 25 orbital locations. Together, they deliver over three thousand TV stations and over 2000 radio stations to 200 million cable and satellite homes. The transition to HDTV represents a challenge and opportunity to these providers and implies a possible future need to work more closely with the terrestrial broadcasting community. There are no stated plans by either entity to implement a hybrid ATC network, however, an S Band payload wase included on the Eutelsat W2A satellite launched in 2008/9 and the companies have a joint venture working on delivering additional S band capacity. The technology, engineering and launch costs of these platforms are already very adequately amortised across a substantial and largely captive subscriber base. S Band capacity can there- fore be added at minimal incremental cost. It could be presumed that Intelsat would have similar economies of engineering, sourcing and subscriber scale that could be applied in a similar way. Other present and proposed S Band only providers need to consider the impact this could have on their future operational margins. 16.35 Intelsat C Band Ku Band and Ka Band GSO Intelsat¹7 provides bidirectional transponder services to corporate and national governmental markets predominantly at C Band (3.4 to 7.025 GHz), Ku Band (10.7 to 14.5 GHz and Ka band (17.3 to 30 GHz). Intelsat has 51 geostationary satellites and uses spot beams to provide global, hemi, zone or spot beam coverage predominantly to fixed users. There are no stated plans for a hybrid ATC network.
