(1) Mobile　 communication which increase rapidly

Mobile phone, including PHS(personal handy phone) subscribers became 60 million and exceeded telephone subscribers on last July.

The　cause of rapid growth in only 21 years compared with ( fixed type) telephone which has 110 years history are as follows:

It is that mobile phone had a function of the mobile computer terminal to replace the personal computer which have been having exclusive attention as a leading part of IT (information technology) until now in addition to the part as a telephone.

It was popularized rapidly as a portable handy terminal which exceeded a personal computer since the NTT DOCOMO start the Internet connection service "the i mode" on September '99.

The reason of that mobile phone subscriber exceeded telephone subscriber is another company started similar service such as EZ-WEB by KDDI and J-SKY by J-PHONE.

Though once Japan took a top position of the IT in the world, USA replaced it.

However we have possibility to pull out again it with mobile phone.

(2) Will PHS(Personal Handyphone System) soon restore ?

In contrast with mobile phone, subscribers of PHS decreases from 7.1 million units as peak in September '97 to 5.7million units in last March.

Due to the image of cheap portable phone when price competition, subscriber of PHS decreased.

PHS was born from the idea that the child machine of dizital cord less telephone was handled outdoors from the first.

An antenna is installed in several hundred meter apart, and having a strong point of the transmission ability of the big capacity of 32 kbit or 64 kbit.

But, there is a fault that a service area is small due to installation sysytem of the antenna.

There are signs of restoration of PHS with the service, which applied the advantage of characteristic of PHS ,as follows:

(3)PHS position reference information service

It is the service of informing the position of the person who has PHS by using the PHS antenna net installed in several hundred meter apart.

Precision is higher than the similar service of the portable telephone.

We can know the position of the child of the late return and the old man whose position nobody knows.

(4)Data communication service and music deliver service.

The transmission ability of the big capacity and the high quality of sound are the strong points of PHS.

NTT DOCOMO has started the data transmission of 32 kbit/second in 97 and 64kbit/second since April '99.

A data transmission ratio in the total sending time of PHS in this April exceeds 50%, and exceeds the voice.

The data transmission of 64 kbit/second becomes possible with PDA (the terminal of the portable information) notebook personal computer by the compact flash card type PHS and without connecting a cable.

DOCOMO does the monitor experiment of the music monitor deliver service (MMD service) by PHS at present in cooperation with Matsushita Communication Industrial Co.,Ltd. and so on.

It is that transmits music in the miniature regenerated device through PHS and it will start business service coming autumn.

(5) Portable telephone and the compound terminal of PHS

DOCOMO introduces the compound terminal "DOCHIMO" the terminal of the compounding which complied with the mobile phone and 64 kbit/s PHS and moreover they introduced the compound terminal complying with i mode on last June.

It is possible maximum about 1500 characters/matter of sending and receiving.

They will introduce a PHS which possible receive and send of the animate cartoon figure of the color on coming autumn.

(6) Diffusion in the developing country

PHS will be used mobile phome instead of telephone in development country because

PHS has advantage of low cost and short time for make out communication network.

The Bank of Japan announced a release of zero interest policy recently.

A big factor is consumption in the economy index though they argument as that one say as economic condition changed to up

And another say it is still sluggish.

In spite of eexpensive 10 times of communication fee than telephone, mobile phone sells well like a cake though in such depression.

The consumer has anything which they want.

It will be not that the consumers don't buy the commodity due to depression but there is no superior commodity.

The thumb culture which it is proud of in the world spreads out rapidly to the world as a leading part of the next generation telephone.
