  2. An Application of mmWave System- Video Transmission System - This system has been developed by YRP Collaboration Research Project on Millimeter-Wave Video Transmission Systems Hiroyo Ogawa, CRL

  3. Outline 1. Introduction 2. Background and concept of mmWave video transmission system 3. Developed MMIC-based experimental transmitter and receiver 4. Result of successful demonstration 5. Conclusions Hiroyo Ogawa, CRL

  4. Introduction ■Advantage of home-use radio system (home-link) using 60GHz band ・Frequency confusion less than 30GHz-band -Technical advance of millimeter-wave devices -Shift to higher frequency band ・Demand for multi-media communications -Need for broader frequency band ・Unique characteristics of millimeter-wave transmission -Line-of-sight propagation -Interference avoidance using antenna’s directivity -Attenuation by atmospheric oxygen (16dB/km@60GHz) Hiroyo Ogawa, CRL

  5. mmWave Video Transmission System ■ Background: - Popularization for wall-hanging, small and flat TV - Personal use of TV with chance of digital broadcasting ■ Problem: Complicated connection of feeder-line ■ Need for “wireless” video transmission system as “Replacement of Wire” Hiroyo Ogawa, CRL

  6. System Conceptual Image Home base station CS BS Passport size Terrestrial TV Control circuit Flat ANT Wall-mount TV Transmitter LCD TV Portable PC within TV tuner MMIC DV D Power supply CATV Feature: - One-way simple transmission system for cost-effective equipment - Broadband wireless-link for multiplexing (TV broadcasting, Video, Data, etc.) - Small-size all-in-one-type mmWave RF devices Hiroyo Ogawa, CRL

  7. System Utilization Image Service distance 10-m as typical value High of Tx Around 2-m high on the wall High of Rx Around 1.5-m on the TV Antenna adjustment Manual or remote control by using level indicator Access point　　 　 Point-to-Multipoint (Reflector is available) Hiroyo Ogawa, CRL

  8. Demand Prediction in Japan ■44 million TV viewer for terrestrial broadcasting, 12 million TV viewer for BS broadcasting - 4.4 or 1.2 million market for assuming 10% viewers ■ 11 million TV products for a year - 1.1 million market for 10% produced TV ■ Considerable wireless applications concerning low-cost mmWave devices - Widely applicable systems (wireless access system, ITS, Wireless-LAN etc.) for low-cost devices Hiroyo Ogawa, CRL

  12. Conclusions • A mmWave video transmission system, as one of attractive mmWave systems, has been presented • This mmWave system can be potentially applied not only for video transmission system but also for various wide-band communication systems • ARIB standard (standard of Association-of- Radio-Industries-and-Businesses of Japan) of this system will be presented at Vancouver meeting Hiroyo Ogawa, CRL
