  1. SuperComm Report Michael Childers LightStream Communications

  2. Five Key Words at SuperCOMM Wireless Optical IP Convergence Broadband

  3. Evolution from 2G to 3G • 2G= Second Generation Wireless • 3G=Third Generation Wireless • 3G is driven by the demand for connectivity

  4. Evolution from 2G to 3G • 2G is circuit-centric…dependent on switch integration • 3G is IP-centric…switch independent

  5. Evolution from 2G to 3G • 2G provided basic Web-browsing • 3G provides full Web-browsing • 2G provided access to e-mail • 3G provides e-mail with attachments

  6. Optical Networks • Circuit-switching creates hard connections • IP networks create virtual connections • Optical networks depend on light rather than electronics; photonic switching transmits light as light without conversion

  7. Optical Networks • Expand via signal multiplexing rather than fiber multiplication • Dense wavelength division multiplexing (DWDM) splits colors into multiple paths enhanced by tunable laser technology and erbium-doped fiber amplification

  8. Optical Networks • Today’s networks: • Process 40 colors… • Split each color into 160 wavelengths… • Carry 1022 wavelengths on a single fiber strand… • Providing 6.4 terabits of throughput

  9. Optical Networks • One Tbps can deliver: • Every television broadcast in the world simultaneously • 500,000 movies simultaneously… • …over one fiber strand

  10. Cellular Telephones • U.S. cellular system is based on AMPAS (Advanced Mobile Phone Service) • AMPAS is used in about 90 countries • Other standards: • Nordic Mobile Standard (NMT) • Total Access Communication Service • Global System for Mobile (GSM)

  11. Cellular Telephones • GSM evolved as an all-digital service for roaming in Europe • There is an effort by the ITU to reduce interoperability problems using 3G

  12. Cellular Telephones • Existing AMPAS systems use Frequency Division Multiple Access (FDMA) • In 1999, CTIA agreed to develop a digital standard • In 1991, TIA released IS-54 using Time Division Multiple Access (TDMA) • IS-54 is replaced by IS-136

  13. Cellular Telephones • In 1993, TIA approved a second standard (IS-95), using Code Division Multiple Access (CDMA) • TDMA & CDMA refer to standards for multiplexing

  14. 3G Standardization • 131 specifications have reached publication as standards for 3G applications • “Release 99” - made public by the 3GPP in December 1999 • ITU’s standards group known as IMT-2000

  15. 3G Standardization • The new generation of specs will permit: • Global Roaming • Internet Access • Multimedia Services up to 2Mbps • Standards based on all-IP network

  16. 3G Standardization • GSM will evolve from 2G to 3G via ETSI’s interim standard called EDGE…Evolved Datarates for GSM Evolution • GSM will evolve to EDGE, than to UMTS…Universal Mobile Telephone Service

  17. Wi-Fi…Broadband Internet Access • Wi-Fi= A trademarked term referring to “wireless fidelity” • Wirless LANs made possible by wireless Ethernet • Targets “public hotspots”: • Airports, hotels, convention centers, universities

  18. Wi-Fi vs. Cellular • Cellular: GPRS, UMTS, EDGE • LAN: Wi-Fi, IEEE 802.11b, 2.4 GHz • Cellular: <400 Kbps; Ubiquitous • LAN: >11 Mbps; Localized

  19. Wi-Fi…Broadband Internet Access • Delta Airlines planning to equip: • Atlanta, Boston, Chicago, Dallas, Fort Lauderdale, LaGuardia & Kennedy, Los Angeles, Orlando, Salt Lake City, San Francisco, & Washington DC • …plus plans to implement onboard

  20. Wi-Fi…Broadband Internet Access • Wireless Ethernet Compatibility Alliance (WECA): • 42 members, including-Lucent, Cisco, Intel, 3Com, Compaq, IBM, Nokia, Philips, Dell, Sony, Intersil

  21. Fixed-Mobile Convergence • 3G-UMTS and Wi-Fi are expected to converge • UMTS will result from the convergence of TDMA & CDMA with GSM

  22. Fixed-Mobile Convergence • GPRS & other next-gen standards will require IP addresses to provide Internet access • 32 million GSM IP addresses will over-tax IPv4, and will require IPv6

  23. “The Connected Traveler” • IPEC 2001: 25-27 April, 2001 • New technologies make it possible to connect the traveler in the air, the airport, & beyond. This connectivity has the ability to be seamless.

  24. “The Connected Traveler” • Identify all the services that connect travelers • Identify all of the networks, backbones & supply chains that provide platforms • Identify network access points and user interfaces that provide access

  25. “The Connected Traveler” • What are the issues involving systems integration, interoperability, and standardization? • How do we make these services operate together?

  26. Digital Cinema • Three potential forms of digital delivery: • a) highly-encrypted DVD • b) satellite • c) fiber optics

  27. Digital Cinema • On June 7, 2000, the world’s first network delivery of a major motion picture from studio to exhibitor took place across a VPN. • The movie was “Titan A.E.”, a 42-gigabyte file.

  28. Digital Cinema • 1) Content cache from a QuVIS Server • 2) Cisco 7140 VPN Router • 3) DS3 fiber optic path • 4) Cisco 7140 VPN Router • 5) Content cache in a QuVIS Server • 6) TI’s DLP Projector

  29. Summary • Please read the AVION article • Please put IPEC on your calendars, and encourage WAEA to work together to ensure IPEC & WAEA educational sessions are complementary • Put SuperCOMM on your schedule • Prepare for a broadband, wireless, optical future.
