Presentation Outline About Nortel Networks Market Dynamics Role of Satellite Evolution vs. Revolution Satellite Multimedia Evolution Path Summary2

Corporate Profile Nortel Networks works with customersworldwide to design, build, and delivertelephony and IP-optimized networks. Customers include:— public and private enterprises and institutions;— Internet service providers;— local, long-distance, cellular & PCS communicationscompanies;— cable television carriers;— satellite operators; and— utilities Focused on superior value for thecustomer3

Dynamics of Broadband Access Market Pent up Demand for xDSL, Cable Modem, and LMDS— Operators: GTE, NorthPoint, Metricom, Advanced Radio Telecom,Teligent, WinStar, .— Manufacturers: Nortel Networks, Lucent, Alcatel, Intel, Broadcom,Copper Mountain, Newbridge Networks, . Large Carriers Acquiring Cable Companies to ProvideBroadband Access— AT&T buy out of Media One and TCI ISPs and New Operators Looking to Alternate Means ofProviding Access to Users— AOL Investment in SpaceWay & DirecPC for Satellite Access— Teligent and WinStar using LMDS— Utility Companies using power lines5

Satellites Traditional Role Original use for point to point TV distribution(Telstar) Evolved into trans oceanic telephony trunking(Intelsat) Step out into thin route telephony (Spade andDomsats)6

Satellites in Broadcast Satellites always have been good at broadcast(wide area coverage) First application was for narrow band messaging Lower cost ground segment invoked a DTH roleand a data broadcast role Data broadcast (Equitorial) in C Band preceededtwo way VSATs in Ku Band7

Direct-to-Home Key element is the availability of low cost receivers inthe home unit RF technology benefited from standards in EIRP fromthe satellite driving a standard receiver package Analogue broadcasts were not susceptable todiverging standards. Used existing TV standards Introduction of digital TV drove the need for astandard8

Digital TV First roll out in North America used a propriatorytechnology (Hughes Direct TV) Europeans were more active in promoting a commonstandard DVB/MPEG2 (SES Astra) North Americans now realising the benefit of thisstandard (EchoStar, Express-Vu) A manufacturing community exists in support ofDVB/MPEG (Philips et al)9

Two Way VSATs Takes advantage of the wide area coverage Often bundled with a business TV application. Some benefits from a standardised RF system.— Standard satellite EIRP and interference environment (1.8mpackage) Suffered from a lack of a digital standard— Proprietary FEC coding, modulation, MAC layer and transmissionrates10

Multimedia Satcom(Revolution or Evolution)Revolution Much hype from the revolutionaries (Teledesic,Celestri, Skybridge, Astrolink) Revolutionary in orbits, technology, cost models orinvestment needs Rationalle based on lower delay, increased capacity,applications (mesh) or combinations of these. Clear role in the future for LEO based overlaysdelivering symetrical bandwidth for highly interactiveapplications. Also attractive for 3rd generation mobile(FPLMTS)11

Multimedia Satcom(Revolution or Evolution)But Ignores the role of Regional Satellite Systems Doesn’t fit the profile of early applications (highassymetry, multicast) Promotes proprietory air interfac

the satellite output power to the maximum level, additional noise is introduced into the link from satellite to hub. Therefore, an accurate calculation of the SNR for the entire RTN link must consider: 1. the SNR of the terminal-to-satellite link 2. the SNR of the satellite-to-hub link When the output power of the satellite is at a maximum, SNR .

c. Satellite: Internet access provided through satellites orbiting the Earth. Satellite service requires a satellite Internet subscription from an Internet satellite service provider and a satellite dish. Carriers that provide satellite Internet service are DIRECTV, Dish Network, HughesNet, and Wildblue. d.
