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

The TACS format is the communication standard in Britain. DDI and Union Communications (NUCT) have introduced foreign technologies.

It’s just that because Shirakawa Electric and NUCT move too fast, NTT is a little slower.

However, NTT may not have expected that because Shirakawa Electric's mobile phones are so popular.

They are the same as DDI's idea, which is to ask Shirakawa Electric to help them produce mobile phones that support the NTT format, which is the HICAP communication standard.

There are two companies that have officially launched mobile communications business, one is NTT with state-owned background, and the other is NUCT with the Caibao Group's new industry layout.

Shirakawa Electric's profit source is part of the whole machine. At the same time, Shirakawa Electric can also receive a part of the commission in DDI's tariff package.

Of course there is, but because of the speed of layout, neither IDO, DDI or TWJ have completed the base station construction.

In fact, there is no technical difference between contract phones and full network mobile phones. The difference is that you can turn on the corresponding frequency band by browsing the program.

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

Since NTT does not agree, there is no way Shirakawa Electric can only produce mobile phones that support NTT format alone, and can only be sold in IDO's franchise stores.

In short, the current mobile communications market is a mess, the formats are incompatible, and they are incompatible.

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

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

These mobile phones are compatible with both GSM and TACS formats, and to some extent, they are a full-network mobile phone.

However, it would be awful to use DDI with the TACS standard, because the only two mobile phones on the market do not support the TACS format.

This communication standard was developed by NTT itself. As the predecessor of a state-owned institution, its various research institutes are very complete.

This is a mainstream cooperation method between contract machines and operators, but because mobile business belongs to emerging industries, some places are not perfect enough.

But Shirakawa Kaede is different. He has seen various designs of mobile phones in later generations.

What it signed with NTT is just a format application agreement, which does not include content like mobile phones that must be produced with NTT.

Nowadays, mobile phones are contract machines bundled with operators, which means that mobile phones are not common to each other.

It is understandable that IDO comes to him, after all, he has no choice.

Therefore, after the reform, the contract machines of each business hall began to be tied up one-on-one.

Since then, this phenomenon has been greatly reduced.

However, although there was a storm, the popularity of Shirakawa Electrical Mobile Phones can also be seen.

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