It is expected that various radio spectrum
uses have been drastically expanding in
such areas as the home, business,

nationals, so that the radio spectrum uses
contribute to realization of convenient/

[Definition of market sizes of radio-related industries]
Core Radio-based Industries: Sales amounts of industries in which the usage of radio spectrum plays the central role of businesses (e.g., radio
communications carriers/broadcasters, manufacturers of radio communications/broadcasting equipment, etc.)
Industries Using Radio (radio-related amounts)*: Radio-related partial amounts of the total sales of industries in which the usage of radio spectrum does
not play the central role in business, but cannot operate business activities without using radio spectrum (energy suppliers, such as power and gas
utilities, airline, maritime, railway and automobile transportation services, etc.)
Industries Potentially Using Radio (radio-related amounts) *: Radio-related partial amounts of the total sales of industries whose businesses are not using
radio spectrum at present, but whose products and services will be highly improved and become effective through radio spectrum use in the future
(distributors, education, medical/nursing care/welfare services, games, etc.)
* Note: Upon estimate, market sizes are calculated by multiplying annual sales amounts (annual growth rates are considered) by degree of dependence on
radio spectrum use.

- 330 – 340 MHz bandwidth (5 years later)
- 1,060 - 1,380 MHz bandwidth (10 years later)

- The frequency band that can be used for outdoor applications has
been greatly expanded.
⇒ More users are able to use faster communications.
-Common frequency bands that can be used on a worldwide basis
have been expanded.
⇒ Users can benefit from improved convenience and less
expensive equipment.
