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)

■ 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”

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

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
