When the first working model of an artificial satellite by Hughes Aircraft was displayed from the top of the Eiffel Tower, in 1961at the Paris Air Show, the sceptics remarked that it was as high as it would go1. Today, with over 900 satellites orbiting the Earth2 the proponents of satellite technology are having the last laugh. Around the mid 1990s, “packet-switching technology” and “the Internet” – both of which led directly to the development of broadband technology, satellite and terrestrial networking enabled multimedia traffic, voice/video/data/fax, to be carried over ‘converged’ data networks. The terms Voice Over IP (VoIP) and IP Telephony (IPT) were introduced to describe how circuit switched voice signals were converted into data packets for transport on IP networks.3 Since the opportunities for convergence of data, voice and multimedia (video) on the same network are now offered by IP, satellites, with their inherent strength to cover mass geographical coverage are offering a sound solution. Satellites are therefore seen as powerful transmission tools for broadband applications. But many regulatory barriers and uncertainties need to be overcome, at both the international and national levels. This paper defines the universe of broadband satellite technology and explains why it is so vital for the expansion of multimedia services and applications around the world. In order to help readers fully appreciate the potential of satellites, this paper will briefly describe their system architectures, the technical characteristics of air interfaces, 4 and the different broadband services and applications that can be delivered through satellite systems. Subsequently, the paper deals with international, regional & national practices for satellite system approaches for broadband delivery. Description of satellite as a component of `IMT-advanced’ and use of satellites for disaster relief work is then explained. ITU practices for use of spectrum/orbit resource and some of the important satellite coordination issues that have the potential to block new satellites (including the ones that may serve the broadband markets) and that are to be discussed during the ITU World Radiocommunication Conference-12 (WRC-12) early in 2012, are then introduced. Aspects concerning the economics of satellites systems and market entry issues are followed by thoughts on best satellite regulation practices and challenges to further broadband access for all. 1.1.1 What is broadband and what does satellite broadband mean? Broadband, which also may be referred to as `wideband’ is used frequently to indicate some form of high-speed access. There is however, no universally accepted definition for this term. Broadband is frequently used to indicate an Internet connection at 256 kbit/s in one or both directionsi. The FCC definition of broadband is 4.0 Mbit/s. The Organization of Economic Co-operation and Development (OECD) has defined broadband as 256 kbit/s in at least one direction and this bit rate is the most common baseline that is marketed as "broadband" around the world5. However, for the purposes intended in this paper, the term `broadband’ refers to data rates that correspond to the user rate of 2 Mbit/s and higher (also refer section 1.2.4). Not everyone is able to access DSL (Digital Subscriber Line) or cable service, particularly in rural areas, where the subscribers may not be well served by the phone centre. For those left out, satellite broadband can be the answer. The Internet feed is beamed from satellite to a dish installed at the subscriber's home. Typically, a two-way Internet access via satellites rather than dial-up, capable of delivering speeds equal to or greater than 2 Mbit/s downstream, and 1 Mbit/s upstream 6, would fall in the category of satellite broadband. Broadband satellite7 also refers to systems that have the capability to receive and transmit `rich media content’ from the satellite to the network end- users and between the end-users whether at home or in the office. Satellite broadband can also include a hybrid solution, where the “middle mile is provided via satellite and extended to end-users via terrestrial IMT technologies. 1.1.2 Why satellites for broadband delivery? According to ITU World Telecommunication/ICT Indicators database8, “There has been strong growth in fixed (wired) broadband subscriptions, in both developed and developing countries: at the end of 2010, fixed (wired) broadband subscriptions reached 8% penetration, up from 6.9% penetration a year earlier. Despite these promising trends, penetration levels in developing countries remain low: 4.4 subscriptions per 100 people compared to 24.6 in developed countries.” 1 Regulation Global Broadband Satellite Communications Recognizing the fact
