"Everyone, it's an exciting time. Today is a great time to verify the practical application of our cdma network!!" In the conference room of a hotel in a building in Hong Kong Port, dozens of foreigners, some local officials, and some local reporters all showed excited expressions on their faces.

These dozens of foreigners are technical personnel from Qualcomm Group in the United States. In addition, Irving Jacob, chairman of Qualcomm Group, today is an extremely important day for Qualcomm Group. Because Qualcomm Group has worked hard to develop a CDMA communication network for four years, regional experiments are finally about to start.

The cdma communication network is a wireless mobile communication network mainly based on cdma technology, that is, the communication network of mobile phones.

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

In one month, Qualcomm has arranged 18 signal transmitters throughout the port and 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 more than 200 staff members holding CDMA network chips to distribute them in various locations in Causeway Bay, and then let them call each other. As long as the voice of the call between the two parties can maintain a high stability and can conduct a certain high-capacity signal transmission, even if the operation experiment of the CDMA network is successful, the CDMA network will also be approved by 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, CDMA can obtain an entry permit to enter the market, and the CDMA network can also be proven to be a network that can be used in reality.

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

Qualcomm has been studying technology for 4 years and can monetize it, instead of continuously burning investors' money like in the previous six years.

Simply put, as long as the experiment is successful, Qualcomm can make money.

So at this moment, all Qualcomm Group was very excited.

"Chairman, it's 9 o'clock in the morning!" Irving Jacob's secretary reminded in a low voice. Irving Jacob nodded with a rosy face, and at the same time said to more than 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. The whole scene can be said to be very science fiction, as if you can control the base station several kilometers or even ten kilometers away through this button.

But in fact, there have been staff from Qualcomm Group near the power controllers of these base stations, and they don’t have to wait for a phone call.

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

"Chairman, please call the experimenter!" the secretary said excitedly, while Owen Jacob waved his hand and gave the phone to an official in the port and port beside him, saying, "Let me come first, you can make this first call. This is the first mobile phone in the world that has been broadcast on the CDMA network!"

"Okay!" Mr. Lin blushed when he heard this. Thinking that he might have recorded human history because of this call, he was very excited to pick up the mobile phone in Irving Jacob's hand.

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

It is always out of touch with the phone numbers above 10 digits in later generations. All the phone numbers on this document are 4 digits. This is really the first batch of mobile phone numbers born on CDMA in the world!

"2233!" In excitement, Mr. Lin dialed one of the most interesting numbers.

"Beep!" With a familiar sound, the phone successfully dialed out, and the faces of others around him suddenly showed extremely expectant expressions on their faces, 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 beeps like this, then there is no sound, and finally a squeaking current sound even came out of the microphone.

"It's okay... it takes a little time to turn on the signal at the beginning..." Owen Jacob's expression became a little stiff, but he still forced himself to explain. But after waiting for a full minute, no sound came out, but the sizzling current became louder.

"Damn it, this is that the mobile phone cannot connect to the base station. Is there a problem with the signal reception?" As the chairman of the technology, Irving Jacob is naturally very clear about the equipment he has developed himself. As long as he hears the sound from the phone, he can tell where the problem is.

"Sorry, there may be some problem with the base station No. 12. I will send someone to repair it!" Owen Jacob said quickly, then took out the walkie-talkie with a pale face, adjusted the channel, and issued an order to the staff responsible for the base station No. 12, asking them to repair and adjust the base station immediately.

"Yes! Let's go now!" The staff stationed at base station No. 12 immediately rushed to the top floor in a hurry, opened the base station directly, and began to concentrate on finding the base station problems.

At this moment, the security guard who stood at the door of the top floor and stared at the flag at the top of the Golden Dragon Building in the distance suddenly found that the color of the flag changed from green to red.

So he reached into his tool kit and closed the switch that was originally opened.

"What should I do? No problem can be found!"

"That's it! There's no problem!"

The two maintenance engineers in charge checked for a long time but found no problem. They could only unplug the power supply, restart the base station, and then responded to Irving Jacob, asking them to test it again.

"Then let's try again!" Owen Jacob said with a stiff expression. Mr. Lin also called the phone again in embarrassment, but this time it seemed that it had been repaired. The phone was successfully dialed, and a person's voice came out of the phone. He also complained, "Why did the phone call come so long? It's more than ten minutes late!"

Irving Jacob did not get angry with the experimenter because he breathed a sigh of relief. It seemed that it was just a small problem just now, but now it has finally succeeded.

Mr. Lin also began to talk to the experimenter and asked him about some of the situation. As everything was getting better, Irving Jacob did not notice that the flag at the top of the Golden Dragon Building not far away changed from red to green.

Then, with a squeak, the call was just smooth and hung up instantly, and it became a state of inaccessibility again.

Irving Jacob's face was ashen. At this time, the staff in charge of communicating with 200 experimenters on walkie-talkies sent a report saying that some of the experimenters could actually answer the phone, and most of the experimenters could not get through the phone.

"Go and repair the base station quickly!" Owen Jacob said irritably. The engineers under his command had to repair the base station again. As a result, some base stations returned to normal, but some base stations could not work normally, and some base stations were interrupted and stopped.

In short, the performance of the cdma network is extremely unstable, with various disconnections and disconnections, and signal failures occur from time to time. The entire network is in a state of inability to work for about half of the time.

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

In the eyes of professionals, this is entirely because the communication base station and the communication technology network of the CDMA are very unstable, and the internal circuit design is unscientific and various electronic components do not match, so it will be normal to turn off and then turn on, and then fail after a while.

This set of equipment is full of technical defects and cannot afford the communication tasks of a big city at all.
Chapter completed!
