  • c ompetitive l ocal e xchange c arrier Incumbent local exchange carrier
  • Los Angeles existing DTV station KMEX-TV, ch. 35, was selected. Tx2 and Tx3 are hypothetical. Transmitter parameters: KMEX-TV: 400 kW ERP, 98 m AGL, dir antenna pointing South-West ° Tx2: 10 kW ERP, 50 m AGL, dir antenna pointing West Tx3: 5 kW ERP, 50 m AGL, dir antenna pointing North-East Receiver parameters: Fixed: Field strength 41 dBuV/m, 90% service availability, antenna height 10 m Mobile: C/N+I = 15 dB, 90% service availability, antenna height 1.5 m Path Loss: CRC-PREDICT v3.21, elevation and Land cover data using Computamaps (500 m resolution) Echo cancelation: The equalizer values used for echo cancelation were -10 to 45 usec and 3 dB C/N+I diff., these values may need to be reviewed and would consequently affect the coverage slightly. Low power transmitter, combined with directional antennas and the terrain elevation (mountains) were used to limit self-interference. Addition of gap filler or coverage extender in the SFN needs to be done carefully, it is easy to cause self-interference, need for advance simulation tool for planning.

      • Broadcasters sit on a lot of unused spectrum
      • Broadcasting is not spectrum efficient
      • Broadcasting can not adapt to new standards, new technological progress, new service requirements…
      • STANDARDS are prisons in the face of the ever faster technological progress
      • The convergence among the various delivery networks will lead to the death of Broadcasting
      • There is no business case for Over-the-Air digital broadcasting .
      • The next wireless communication systems will deliver hundreds of megabits to any handheld devices anywhere, anytime.

        • But some disadvantages
        • Lack of (very expensive) spectrum
        • Cost of the smaller cells required to increase capacity
        • Lack of infrastructure robustness against disasters
        • Smaller and more expensive coverage than broadcast

    • 11. Does wireless communication threaten broadcasting?
        • No if current OTA model of broadcast distribution (free spectrum, free broadcast service) is maintained
        • Possibly yes, if current model changes and wireless carriers:
              • Are able to charge for OTA broadcast video
              • Have the necessary spectrum made available ($$$) to them
              • Have access to one-to-many delivery capability
              • Can support valid television broadcast video business models
        • Not likely to threaten broadcast production , since it is distinct, but Internet content providers may...
        • Will not threaten broadcast technologies , in fact may adopt them
        • Ultimately, policy, regulatory decisions and spectrum allocation/conservation may determine the survival of broadcasting as well as the strength of the Telecom Business Case

      • The future of TV is on the Internet and over-the-air.
      Myths or realities ?
    • 28. Conclusions
      • All the various models will be used to distribute content
      • Users will find out which ones are more appropriate to their lifestyle and budget…or their intelligent devices will find tem for the users
      • Organisations will develop appropriate business plan for each technology.
      • Expect each technology to evolve and to adapt to stay competitive
      • Expect more new models to appears in the future taking advantage of technical progress
      • Broadcasting is a public services (e.g. Emergency Alerting) which requires spectrum and government regulations to succeed
      • Next generation broadcasting systems must be international
      • FOBTV has important roles to play.
