Chapter 452: Lost Adult

"Everyone, it's an exciting time, and today is a great time to validate the practical application of our CDMA network!!" In the conference room of the hotel in the first building of the port building, dozens of foreigners, some local officials, and some local reporters all showed excited expressions on their faces.

These dozens of foreigners are technicians from Qualcomm Group, and Owen Jacob, chairman of Qualcomm Group, today is an extremely important day for Qualcomm Group, because Qualcomm Group has painstakingly developed the CDMA communication network for four years, and on this day, it is finally time to start regional experiments.

CDMA communication network is a wireless mobile communication network based on CDMA technology, that is, the communication network of mobile phones.

To put it simply, it is a mobile phone signal based on a CDMA signal.

In a month's time, Qualcomm deployed 18 signal transmitters throughout the port, basically covering the entire Causeway Bay area.

The purpose of the experiment is to verify whether the CDMA network can operate normally and how stable it is.

The test method is also very simple, Qualcomm Group has arranged a total of more than 200 handheld CDMA network chip mobile phone staff, they are distributed in various locations in Causeway Bay, and then let them call each other, as long as the sound of the two sides can maintain a high degree of stability, and at the same time can carry out a certain high-capacity signal transmission, then the CDMA network operation experiment is successful, CDMA network will also pass the approval of the Ministry of Information Industry of the United States, and officially obtain the qualification for listing operation.

This is undoubtedly extremely important for Qualcomm, as long as this experiment can be passed, then CDMA can obtain the market access certificate, and the CDMA network can also be proven to be a network that can be used in reality.

More importantly, they have negotiated with the relevant officials of Hong Kong and Hong Kong, as long as this experiment passes, Hong Kong and Hong Kong will become the first region in the world to install a CDMA communication network, and Qualcomm's first CDMA business can be regarded as a negotiation.

Qualcomm can monetize the technology that has been painstakingly studied for 4 years, instead of continuing to burn investors' money like the previous 6 years.

To put it simply, as long as the experiment is successful, Qualcomm can make money.

So at this moment, all Qualcomm Group is very excited,

"Chairman, it's 9 o'clock in the morning, it's time!" Owen Jacob's secretary reminded in a low voice, and Owen Jacob nodded ruddyly, and at the same time said to a dozen technicians under him, "Start the CDMA signal base station!" ”

"Yes! Start the CDMA signal base station!! More than a dozen technicians pressed the button in their hands at the same time, and the whole scene can be said to be very sci-fi, as if the base station can be controlled a few kilometers or even more than ten kilometers away through this button.

But in fact, Qualcomm staff have long been stationed near the power controllers of these base stations, and they don't need to wait for calls.

They just looked at the watch, waited until 9:00, and then sent power to the base stations at the same time, and then the 18 base stations began to work.

"Chairman, please call the experimenter!" The secretary said excitedly, and Owen Jacob waved his hand, gave the phone to an official in Hong Kong next to him, and said, "Let's let Mr. Lin come first, you come to make this first call, this is the first mobile phone in the world's history to be broadcast through the CDMA network!" ”

"Good!" Mr. Lin was red-faced when he heard this, and he thought that he might be able to record the history of mankind because of this phone call, so he was very excited to pick up the mobile phone in Owen Jacob's hand.

"There are 200 different phone numbers written here, and you only need to enter one of them to talk to any of the 200 experimenters!" Owen Jacob took out a document full of phone numbers and handed it to Owen Jacob.

The phone numbers on this document are all 4-digit phone numbers, and this is really the world's first batch of mobile phone numbers born based on CDMA!

“2233!” In his excitement, Mr. Lin dialed one of the most interesting-looking numbers.

"Toot!" With a familiar ring, the phone was successfully dialed out, and the faces of the other people around suddenly showed extremely expectant expressions, looking forward to the moment when the experimenter on the other end of the phone connected the phone.

But the problem is that the phone just rang like this, and then there was no sound at all, and finally even a squeaky current sound came out of the microphone.

"It's okay...... It takes a little time to answer the signal at first......" Owen Jacob's expression stiffened a little, but he still forcibly explained, but after waiting for a full minute, no sound came out, only the sound of electricity became louder.

"Damn, this is because the mobile phone can't communicate with the base station at all, is there a problem with signal reception?" Owen Jacob, as a technical chairman, is naturally very clear about the equipment he has personally researched, as long as he hears the sound coming from the mobile phone, he can judge what is wrong.

"I'm sorry, there may be a problem with the No. 12 base station, so I'll send someone to repair it!" Owen Jacob said quickly, then took out the walkie-talkie, adjusted the channel, and gave an order to the staff in charge of the No. 12 base station, asking them to repair and adjust the base station immediately.

"Yes! Let's go! The staff stationed at the No. 12 base station immediately rushed to the top floor, directly dismantled the base station, and began to concentrate on finding the problem of the base station.

At this time, the security guard who was standing at the door of the top floor, only staring at the flag at the top of the Golden Dragon Building in the distance, suddenly found that the color of the flag had changed from green to red.

So he reached into his toolkit and closed the switch that had been turned on.

"What to do? I can't find the problem! ”

"That's it! There is no problem! ”

The two maintenance engineers checked for a long time, but they didn't find any problems, so they could only unplug the power supply, restart the base station, and then give Owen Jacob a reply, asking them to try it again.

"Then we'll try again!" Owen Jacob's expression was a little stiff and said, that Mr. Lin was also embarrassed to dial the phone again, but this time it seemed to be really repaired, the phone was successfully dialed, and a person's voice came out of the phone, and at the same time complained, "Why did it take so long for the call to come, it's more than ten minutes late!" ”

Owen Jacob didn't get angry at the experimenter, for he let out a long sigh of relief, and it seemed that it had only been a minor problem, and now it had finally succeeded.

And this Mr. Lin also began to talk to the experimenter, asked him some information, and when he saw that everything was getting better, Owen Jacob did not notice that the flag on the top of the Golden Dragon Building not far away had changed from red to green again.

Then there was a squeak, and the call was still going on smoothly just now, and it hung up instantly, and it became a squeaky and unreachable state again.

Owen Jacob's face turned blue as the staff member who was in charge of communicating with the 200 experimenters on the walkie-talkie came with a report that some of them could actually get through to the phone, and most of the experimenters' phones could not get through.

"Go fix it, hurry up and fix the base station for me!" Owen Jacob said irritably, and the engineers under him had to repair the base stations again, and as a result, some of the base stations were back to normal, but some of them were not working properly, and some of them were intermittently stopped.

All in all, the CDMA network is extremely unstable, with various disconnections and drops, as well as signal failures that occur from time to time, and the entire network is in a state of failure for about half of the time.

By the way, many times engineers can't find a problem, but generally the machine can be temporarily restored by restarting the power supply, but after a while, the problem will reappear.

In the eyes of professionals, it is completely the communication technology network of the communication base station and CDMA itself is very unstable, and the internal circuit design is not scientific, and various electronic components do not match, so that the power off and then power on will be normal, and after a while, it will fail.

This set of equipment is full of technical flaws, and it is simply not able to afford the tasks of communication work in a large city.

"Mr. Jacob, it's not early, we have other work to do, so let's go first!" Mr. Lin said apologetically, and then left directly with a vote of government officials, while the reporters at the scene frantically flashed their flashes and kept taking pictures, along with the face of the president of Qualcomm.
