NTT was spun off from the Nippon Telegraph and Telephone Corporation in '85, and today retains its name and is collectively known as the Denden and Telephone Corporation.

If NTT is a descendant of the Nippon Telegraph and Telephone Corporation, then KDD (International Telephony) is a side branch that was spun off.

There is a certain relationship between the two, which is considered to be from the same department under the Ministry of Postal Affairs.

However, there is no doubt that NTT, as a descendant, has inherited most of the business of the Telecommunications and Telephone Corporation in Japan, and the users of fixed telephones are basically under NTT's umbrella.

As for KDD (International Telephony), it only took away the international and domestic long-distance services, which can be regarded as mainly overseas business.

Therefore, after seeing that Shirakawa Electric and NUCT jointly launched a mobile phone with GSM signal, the most urgent thing is NTT.

Local calls, short-haul and most fixed-line services are within NTT's main business scope.

Now that NUCT has released mobile communication mobile phones in advance, it is carving up its future fundamental market.

Therefore, just a few months after the launch of Shirakawa Electric mobile phone, NTT also launched its first generation of mobile communication mobile phone.

In fact, NTT has been doing this project for a long time, and in the past few years, the car mobile phones on the market are basically NTT products.

So in terms of technology accumulation, NTT has its own two brushes.

It's just that because Shirakawa Electric and NUCT are moving too fast, NTT is a little slower.

NTT's TZ-802 mobile phone continues Motorola's early design style.

With the same brick design, you may not be able to hold it in the palm of your hand. It weighs up to 900g, which is close to one kilogram.

After all, as the originator of the mobile phone industry, Motorola is also a subconscious action under normal thinking habits when it is regarded as a reference object by NTT.

But Shirakawa Kaede is different, he has seen all kinds of designs of mobile phones in later generations.

Where technically possible, the semi-clamshell design is a breeze.

Therefore, in terms of recognition, Shirakawa Electric's ONE series mobile phones are unique.

There is no doubt that such a design is also too much more than the brick machine in terms of aesthetics.

However, with its previously large user base, NTT's mobile phone was released a few months late.

But soon, it caught up with NUCT. At present, the number of users of the two operators is almost not much different, both of which are around 500,000 or 600,000.

And with the improvement of infrastructure, both are growing rapidly, and this phase is likely to continue for a long time.

In terms of communication standards, NTT has adopted its own communication format, FDD-FDMA-FM, also known as the HICAP standard for short.

This communication standard was developed by NTT itself, and as the predecessor of the state-owned institution, NTT has a wide range of research institutes.

From communication standards to the development of mobile terminals, everything is available.

However, neon is not only about these two communication operators, since the privatization of communications in 85, there are several newly established operators with a certain scale.

In addition to the aforementioned NTT, KDD, and Shirakawa Holdings' United Communications (NUCT).

There are also Nippon Mobile Communications (IDO), which was jointly established by Toyota, Daini Electric (DDI), which is centered on Kyocera, Shindenden (NCC), which is a state-owned company, and Nippon High-Speed Telecommunications (TWJ), which is a public interest organization under the Ministry of Construction.

As soon as privatization was opened, powerful enterprises were setting up their own telecommunications groups.

At present, four of the seven mainstream companies have a state-owned background, and three belong to the chaebol group.

There are two companies that have officially launched mobile communication business, one is NTT, which has a state-owned background, and the other is NUCT of the chaebol group, which has a layout in new industries.

And now seeing that these two businesses are so prosperous, can the others not have some ideas in their hearts?

Of course, there is, but because of the speed of the layout, whether it is IDO, DDI or TWJ, they have not yet completed the construction of base stations.

The first generation of communication standards they use, that is, the analog signals of the 1G era, are also diverse.

For example, IDO uses the same HICAP standard as NTT, but DDI uses the TACS format.

The TACS format is a British communication standard, and DDI, like United Communications (NUCT), has imported foreign technology.

However, at this time, TACS will be slowly integrated into the GSM format in Britain, and there will be no further development in the future.

But as an analog signal technology in the 1G era, these are enough.

If you look at the overall situation, you will find that several communication operators of Neon have different communication formats with each other and are not compatible.

And today's mobile phones are all contract phones bundled with operators, which means that mobile phones are not compatible with each other.

Well, the closed gameplay between the small days has been involuted from the very beginning.

It is precisely because of the incompatibility of each other's signals that this can stump the remaining few communication operators.

Fortunately, IDO said that its signal format is the same as NTT's, and NTT's TZ-802 mobile phones can be sold directly in the business hall.

Then quickly carry out mobile communication services, even if the base station does not cover all, it doesn't matter, at least Tokyo, Osaka and other metropolises have been built.

But DDI with the TACS standard is miserable, because the only two phones on the market do not support the TACS format.

There is no way to customize the mobile phone is still under development, in order to enter the market quickly, DDI can only find Shirakawa Electric.

What are you looking for Shirakawa Electric? It was to ask Shirakawa Electric if it would be commissioned to produce mobile phones in TACS format.

In the face of the customers sent to the door, how could Shirakawa Kaede not agree?

He will not be as short-sighted as other friends and deliberately restrict the development of IDO.

Don't forget that DDI's shareholders include Sony and Mitsubishi Corporation in addition to Kyocera.

These three companies either make their own electronic products, or they have related businesses behind the group.

Even if Shirakawa does not accept this order, it will not take a year and a half at most, and they will be able to come up with their own mobile phones.

So without much hesitation, Shirakawa Kaede agreed to DDI's commission and asked Shirakawa Electric to start producing mobile phones that support TACS.

These phones are compatible with both GSM and TACS formats, which is to some extent a kind of all-Netcom mobile phone.

In fact, there is no technical difference between the contract machine and the full Netcom mobile phone, the difference is that the corresponding frequency band is exactly the same when you swipe the program.

So this is not difficult for Shirakawa Electric, just a matter of modifying the program.

For Shirakawa Electric, selling NUCT to its own is profitable, and selling it to DDI is also profitable.

Since it's all about making money, who is it not selling to?

In terms of price, it is 430,000 yen to the outside world, but of course, the price of DDI there is definitely not so much.

Shirakawa Electric's profit source is a part, and at the same time, Shirakawa Electric can also get a part of the commission in DDI's tariff package.

This is the mainstream method of cooperation between contract phones and operators, but because mobile services are an emerging industry, some places are not perfect.

For example, after seeing that DDI used Shirakawa Electric's mobile phone, IDO actually came to the door.

Like DDI, they wanted Shirakawa Electric to help them produce phones that support the NTT format, which is the HICAP communication standard.

It is understandable that IDO came to the door, after all, he has no choice.

But your IDO is mixed with NTT, and you ask me Shirakawa Electric to produce mobile phones that support HICAP format, can he NTT have no opinion?

This is to be a minotaur in person, to be honest, Shirakawa Kaede is a little hesitant.

After all, doing so could offend NTT, which produces its own mobile phones.

Now that foreign mobile phones support the NTTT format, won't the mobile phone market produced by itself be compressed?

However, after the IDO came up with NTT's licensing agreement, Shirakawa Kaede did not hesitate any longer.

After all, IDO is an independent operator, and there are major shareholders such as Toyota Motor and Tokyo Electric Power Company behind it.

It has only signed a format adoption agreement with NTT, which does not include content that must be made by NTT.

So from a legal point of view, it is up to IDOs to use which manufacturer makes their phones.

So there is this scene where IDO also comes to the door, and the reason why IDO chooses Shirakawa Electric is very simple.

That is Shirakawa Electric's One series of mobile phones, which are superior to NTT mobile phones of the same period in terms of technological advancement and aesthetic styling.

This mobile phone, endorsed by Akina Nakamori, quickly aroused a warm response in society because of its fashionable shape.

After all, one is more than 600 grams, and the other is nearly one kilogram, and the visual gap is very obvious.

So what the people like, then the operators will take advantage of the trend to launch.

Therefore, whether it is DDI or IDO, they are all moving closer to Shirakawa Electric.

After agreeing to the IDO to provide NTT-formatted mobile phones, Shirakawa Kaede simply went to talk to the president of NTT, Tsuneshi Mato.

He hopes that Shirakawa Electric can produce a full Netcom mobile phone that supports three formats: HICAP, GSM, AND TACS.

In return, NTT can also produce handsets that support other carriers' communication standards.

Unfortunately, NTT rejected Kaede Shirakawa's proposal.

As the big brother of Neon's domestic communications industry and a state-owned enterprise with strong roots, NTT is very disdainful of the market share of NUCT and DDI.

Well, NTT has proud capital, and its future prospects are indeed broader than those of several others.

At the same time, the internal conservative forces are also playing a role, and they still cling to their background as state-owned capital, and more or less look down on other private enterprises in the future.

Since NTT did not agree, there was no way for Shirakawa Electric to produce mobile phones that supported the NTT format alone, and they could only be sold at IDO's franchise stores.

There is no other way to sell NTT-formatted phones directly on the market.

In addition, Shirakawa Electric can also produce mobile phones that support both GSM and TACS formats.

Because of the two-way authorization, IDOs can also produce similar mobile phones in the future.

As for how customers choose, it depends on which mobile phone does better.

In short, the current mobile communication market is a mess, and the formats are incompatible with each other.

The same is true for hardware, obviously there are only two kinds of mobile phones, but they are divided into 3 categories.

However, NTT may not have expected it, because Shirakawa Electric's mobile phone is too popular.

Many customers buy NTT-format versions of One-series phones from IDOs and insert the calling cards they have made at NTT.

In this way, it is possible to use Shirakawa Electric's mobile phone with NTT's package.

As a middleman, IDO found that his communication package did not sell much, but a lot of mobile phones were shipped.

Although the current business hall is a contract machine, it is not mandatory to buy a mobile phone to buy a package, or to buy a mobile phone to buy a package.

This is all the way to play in later generations, and now the mobile business has just begun, so there are many loopholes.

It is precisely for this reason that it has led to the strange phenomenon of buying a mobile phone from an IDO but plugging in an NTT calling card.

Soon after, NTT discovered the anomaly and began to require one-to-one binding of IDO package fees with mobile phones, and NTT began to do so itself.

However, IDO is procrastinating and refusing to implement it, because the business hall only sells mobile phones, and it is also profitable, and it is quite fragrant.

Seeing IDO happily doing two dealers, NTT was angry enough.

So it threatens to stop opening the NTT communication standard to IDO if it doesn't enforce it.

IDO has a stalk in the neck, you don't let me use it, it's a big deal I'll throw myself into the arms of GSM, and I won't get along with each other completely.

Choked by the reply of the IDO single, NTT really didn't dare to threaten too much.

However, this is short-term quick money after all, and the capital behind IDO is not short-sighted.

Doing so will only cheapen Shirakawa Electric and NTT, but IDO's own communication market share has been slow to rise.

Therefore, after the reform of Yitong, the contract machines of each business hall began to be bundled one-to-one.

Since then, this phenomenon has been greatly reduced.

However, although there was a turmoil, the popularity of Shirakawa Electric's mobile phone can also be seen.

Even the IDO is discussing abandoning the NTT format and preparing to join forces with DDI to fight NTT and NUCT together.
