In recent years the demand for high-speed networking, driven mainly by the rapid expansion of the Internet, has been growing at an exponential rate. While a wide range of wireline and wireless solutions offering broadband connectivity are or will shortly be available, communication satellites are beginning to emerge as an attractive solution in providing broadband connectivity to a variety of users.
The wide area or global coverage of satellites enables service provision to a large number of dispersed users and solve the expensive "last-mile" issue without dedicating to each user cable, fiber, switching equipment ports, etc. The broadcast nature of satellites supports efficiently the transmission of the same message to a large number of stations, making satellites the natural choice for multicasting services. Satellites are also attractive for interconnection of geographically distributed high-speed networks, or for providing other multimedia services to both home and business users. Hence, while much broadband communication today is carried via terrestrial links, satellites will come to play a greater and more important role. This can be demonstrated by the increasing commercial interest in this area and the large number of systems that are currently under development.
On the other hand, considerable research work is under way to overcome some of the serious shortcomings inherent in satellite-based systems, such as significant propagation delays, wireless channel quality, exposure of systems to space radiation, etc. The service focus and nature of satellite systems themselves is also changing, with revolutionary new technologies such as onboard switching, spot-beam technology, inter-satellite links and constellations of systems in a variety of orbits (LEO, MEO, GEO, or Hybrid Orbits), that represent new challenges for the satellite industry.
As with any hot topic today, the World Wide Web offers a wealth of information on satellite systems and networks. In these pages we try to collect some of this information in a somewhat organized manner. We try to focus on links relevant to Broadband Satellite Systems, although we also provide links and information to related topics in the more general areas of satellite systems and communication networks. There is material here that could be useful to a satellite expert, an engineering professional who is ne...

...iness market. However, if satellite access is really going to catch on, as operators hope and believe, then there has to be traffic over the network after five o'clock as well. For that to happen, there has to be a consumer market, which will require much lower priced terminals. "Satellite operators have very aggressive target prices in mind for terminals, which is somewhat disadvantageous for Ericsson, compared with traditional suppliers," says Rudi Omholt. "Our strategy is to take advantage of our experiences and know-how from MINI-LINK and the telecom industry. Our strength lies in our reliability and quality and the fact that we are able to show operators an impressive production capacity and a global presence." Ericsson is following developments in the market for broadband access via satellite with interest, and is trying to put its finger on the desires of customers. By offering terminals and trying to land its first contract, the company hopes to form a stable foundation for new operations. "We will be setting serious requirements that one or more of the major telecom operators express an interest in the satellite market," says Ingmar Karlsson.
3. Shaw Direct provides direct-to-home satellite programming to more than 900,000 subscribers - largest in the country
Due to compression, TV audio and video require less bandwidth and multiple digital TV channels can fit unto one satellite transponder as oppose to a single analogue channel occupying the whole transmission line.

NSSS states a few current trends in space as being “congested and contested” (NSSS, 8), which is shaping our space strategic environment as well as fueling debates for space weapons. “Congested” trend refers to the current “60 nations and government consortia that own and operate satellites and the expectation to have 9000 satellite communication transponders in orbit by 2015.
Launch of the herms in 1976 was world’s first direct to home experimental telecommunication satellite.
Would people be willing to pay $12.50/month for commercial free radio beamed right to their car or home. Well two companies and many big investors are betting about $3 billion dollars that people are willing to do just that. In 1997, the Federal Communication Commission (FCC) granted a portion of the S-band spectrum for satellite radio and two companies purchased use of these bands and started the only two companies competing in the satellite radio business today, namely Sirius and XM. Analysts like William Kidd of CE Unterberg Towpin, predict satellite radio will generate about $10 billion a year in revenues by 2007 (McClean, 2001). However, to date neither of these companies has earned a dime. According to industry analyst though, “its not whether satellite radio will take off-rather it’s a matter of how fast.” (Helyar, 2004). Despite lofty predictions, satellite radio has some big issues to overcome before it becomes a serious threat to the $19.6 billion per year terrestrial radio industry.
Satellite radio is a technology that provides a radically new way to listen to radio. XM’s service makes use of advanced satellite capabilities and elaborates terrestrial receiver architecture to deliver a wide array of high quality radio programming nationwide. In early 1998, Robert Acker, director of strategic planning at XM, needs to develop a marketing strategy for this new radio service. There are several decisions that need to be made by the company in order to finalize the business plan. At fist XM needs to decide which of two business models to pursue, whether emphasis should be placed on charging customers a monthly subscription fee, or whether to rely more on earning revenue through advertising. In addressing this problem, management must consider the value that XM radio could propose for different consumer segments as compared with existing modes of radio (AM, FM) and in relation to its sole competitor in satellite radio – SIRIUS. Besides choosing a business model there is also a need to explore how best to approach and leverage manufacturer and channel partners, considering high unknown and high-risk technology. The purpose of this report is to analyze possibilities and outline possible recommendation on strategies for XM Radio. The following areas will be examined:
Effective competition is widely seen as a key to the development of telecommunications services. The ability of new telecommunications networks to interconnect fairly and efficiently with existing networks is critical to the development of competition. AT&T has undergone numerous changes since its inception in the late 19th century. The McKinsey 7 S framework as applied by Pascale is recommended to manage the changes they are facing to adopt a greater competitive presence in the global economy. In conjunction with this framework, numerous other models were applied to analyse the global competitive position of AT&T. Recommendations for a revised strategy and direction for AT&T have been made throughout this document including two scenarios of how the telecommunications industry might develop towards 2000, while outlining the impact on AT&T.
Background One. Tel was launched by Jodee Rich and Brad Keeling in 1995 (Cook, 2001). At first, it looked to get the advantages from deregulation of the telecommunication industry by reselling other network’s capacity and making money through stock market speculation. Rich and Keeling tried to increase the company’s shares rather than profit the company (Cook, 2001). Initially, One.

Throughout the 1970s, concerted industry efforts at the federal, state and local levels resulted in continued lessening of cable restrictions. These changes, couples with cables pioneering to satellite communications technology, led to a pronounced growth of services to consumers and a substantial increase in cable subscribers.
TVS and telephones are using satellites, and I thought it would be a good idea
...space can change some of design of spacecraft and cost of operations. Economically will be advantageous to anticipate and implement these changes early in the design and manufacture of satellites and launch vehicles.
On October 29, 1969 Lawrence Roberts had created the first two nodes to travel between UCLA and SRI International. This project was originally conducted under the Advanced Research Projects Agency to counteract the USSR’s launch of the Sputnik. After the creation it had been called the Arpanet, and would be used specifically for government networks until the early 90’s. In 1990 the World Wide Web had been created as an online public network for everyday civilians to use. At least three decades later the web has grown to include over a million sites, while maintaining the original governments use to maintain a network between locations.
