The world's richest man started by developing gutter oil

"Look at this section of the code of Lianxing WIFI. They use 256QAM modulation technology. Our current customized standard is only 64QAM. This algorithm is about ten times more complex than ours.

In addition, they also added a technology called MIMO. "Zou Qiuzhen added.

Franz Sachs took the document from the other party and read it carefully.

QAM is a commonly used modulation technique used to transmit data in digital communications.

It can represent digital information by simultaneously changing the phase and amplitude of the signal, thereby achieving efficient data transmission.The basic principle is as follows.

QAM modulation technology is based on the superposition of orthogonal signals.

It divides digital data into groups of bits and maps each group of bits to a specific signal point.

These signal points lie on a complex plane, where the real axis represents the amplitude of the signal and the imaginary axis represents the phase of the signal. By changing the phase and amplitude of the signal, different digital information can be represented.

The modulation order of QAM indicates the number of bits represented by each symbol. For example, 16-QAM means that each symbol transmits 4 bits, and 64-QAM means that each symbol transmits 6 bits.

一个比特数里可以包含2个信息（0或者1），4比特可以包含2^4个信息，6比特就可以包含2^4个信息，所以比特数越多，所能传输的信息量就越大。

Modulation depth represents the amplitude range of each signal point.The greater the modulation depth, the greater the amplitude variation range of each signal point, and more information can be transmitted.

The larger the value of m in m-QAM, the more information can be transmitted and the faster the transmission rate.

In the same way, the larger the value of m in m-QAM, the more complex the algorithm involved.

MIMO technology is a technology that can exponentially increase the capacity and spectrum utilization of communication systems without increasing bandwidth.

It can be defined as the existence of multiple independent channels between the transmitter and the receiver, which means that there is sufficient spacing between antenna units. Therefore, the correlation of signals between antennas is eliminated, the link performance of the signal is improved, and the Data throughput.

"Zou, if we can reverse the algorithms here, can our WIFI also achieve their effects?" Franz Sachs looked at Zou Qiuzhen and asked.

"There is no problem in theory, but in practice it is very difficult. Some equations have only one algorithm, and not every equation has multiple algorithms.

Moreover, it is not enough for us to solve QAM alone. We also need to solve MIMO technology. The whole thing is much more complicated than we imagined.

If we cannot develop products of the same level in the short term, then the field of WiFi can only be temporarily ceded to the other party. "Zou Qiuzhen replied.

If they don't purchase Bluetooth and WIFI licenses from Deep Blue, then they can only use their own backward technologies.

At that time, customers will definitely buy from Deep Blue Semiconductor and use independent solutions to use new technologies.

The reason why Qualcomm and Deep Blue Semiconductor purchased the license from Alliance Star WiFi is that they hope to launch their own products through Alliance Star WiFi. At the same time, purchasing the license from Alliance Star can also fill the gap in their high-end products.

"What if we never develop products of the same level?" Franz Sachs looked at Zou Qiuzhen and asked, hesitating to speak.

"Then we can only withdraw from the field of WIFI. The other party only authorizes the technology of the receiving end and does not authorize the technology of the transmitting end." Zou Qiuzhen replied.

Deep Blue Technology only licenses the receiving end technology to external parties. Without the transmitting end technology, they cannot produce wireless router chips. All they can produce are wireless network cards, or they can integrate the wireless network card technology into the CPU.

To put it simply, Deep Blue Semiconductor has a monopoly on the production rights of wireless router chips.

"In addition, if you look at their Bluetooth technology, they have added an ultra-low power algorithm that can reduce power consumption by 90%. This ultra-low power algorithm is difficult to bypass. We may We need to completely abandon the field of Bluetooth." Zou Qiuzhen said very seriously.

"Boom~boom~boom~"

At this moment, someone knocked on the office door.

A Chinese man in his early thirties opened the office door. The man was Shi Chuanhua, Zou Qiuzhen's student and deputy.

Zou Qiuzhen turned around and saw that the person coming was Shi Chuanhua and asked, "Xiao Shi, what's the matter?"

"Teacher, the radio frequency technology we submitted was rejected. Our patent conflicts with someone else's patent." Shi Chuanhua said and handed a document to Zou Qiuzhen.

Zou Qiuzhen read the document carefully after taking it, but the more he looked at it, the more he frowned. Although the other party's technology was not used in communications, it overlapped with their radio frequency patent, and the other party's patent was issued more than half a year ago. applied before.

If they don't have a way to use this patent, then they won't be able to use the new technology and their 4G speeds will be limited to 70Mbps.

Only by obtaining this technology patent can they increase the 4G network speed to more than 150Mbps.

"Why is it this dark blue semiconductor again?" Zou Qiuzhen said with a frown.

"What's going on?" asked Franz Sachs.

"We have recently updated the radio frequency technology of the 4G network. This technology patent can increase the speed of the 4G network. However, our patent conflicts with their patent. Judging from the other party's patent description, the other party should develop it when developing short network technology. patent.

If we have no way to obtain a patent for this technology, then our 4G network speed will be limited to 70Mbps.

Only with this patented technology can the 4G network speed be increased to more than 150Mbps.

It is very likely that our radio frequency chips will lose market competitiveness because of this patent. "Zou Qiuzhen said.

Hearing Zou Qiuzhen explain that Franz Sachs felt a little headache. Losing the WIFI market had already given him a big headache. If he lost the RF chip market again, what would be the difference between cutting off both of their hands.

"I will arrange a time to fly to China. I must get this patent." Franz Sachs said.

Cupertino, California.

Mr. Qiao is playing with the wireless headset sample that Jonathan Ive just sent over.

Of course, this headset is not as small and exquisite as the fruity AirPods, but this headset is definitely the lightest among similar products. The design of the headset is similar to that of our later sports headphones, but the volume is slightly larger than that of later sports headphones. Click.

Of course, this product is made with chips sent to them by Deep Blue Semiconductor.

Although they have obtained the technical authorization for Listening Bluetooth, it will take a certain amount of time to produce the chips.

What they have to do now is to remove the original Bluetooth module and integrate the Listening Bluetooth module into it.

After all, the cost of using technology licensing will definitely be much cheaper than directly purchasing Deep Blue chips.

"Jonathan, how long can this thing last?" Mr. Qiao asked with great satisfaction after putting down the headphones.

"If you just listen to music, you can listen for 8 hours, and you can use it for 5 hours continuously during calls. The battery life far exceeds all existing Bluetooth technologies." Jonathan Ivey said.

"This battery life is really great. Whether it is paired with an iPod or an iPhone, it is a perfect work of art." Mr. Qiao said happily.

"Thank you for the compliment, Boss." Jonathan Ivey smiled. "I hope that the size of the next generation product can be reduced by another 50%, and its battery life cannot be changed." Mr. Qiao said.

"Boss, I will try my best." Jonathan Ivey gritted his teeth and said.

To reduce the size by half but still maintain endurance, the overall design requirements of the headset are very high. The boss does not know how many brain cells will die with just one order, not to mention that his boss is Mr. Qiao, who is known as the tyrant.

2009 12 Month 3 Day.

In a hotel in Shenzhen City.

After the little farewell, Yin Ruoyue became a female knight last night. Unfortunately, Yin Ruoyue's physical strength was really poor, and she was defeated in just half an hour.

"Ding dong~"

[Product this week: A complete set of RGBW sensor technologies, priced at 1000 million soft sister coins]

[Introduction: The amount of light entering is increased by more than 75% compared to traditional RGB, and the noise is reduced by 45% compared to traditional RGB. Even in the dark, I can clearly take pictures of the acne on your face. This technology includes both COMS and CCD design solutions and algorithms. 】

Han Chen finally woke up after hearing the sound of the system.

"Finally good stuff." Han Chen murmured softly.

In the past two times, the system has provided junk products. The most bizarre one was Marilyn Monroe's original flavored underwear.

This grandmother-generation woman has been buried for so many years, and I don’t know where the system got her original underwear. The most important thing is that this broken system is still selling for 2000 million.

When Han Chen saw the price, it was full of black lines.

After purchasing RGWB sensor technology, Han Chen picked up his phone and checked the time.

At this time, the time has reached 09:30.

"Yueyue, it's time to get up and have breakfast." Han Chen pushed Yin Ruoyue in his arms and said.

"No, I want to sleep for a while longer. If you want to leave, go ahead." Yin Ruoyue said drowsily.

Seeing Yin Ruoyue's dazed look, Han Chen knew that she wouldn't wake up before noon. Han Chen took out a bottle from the bedside wallet, then took out the gene optimization capsule inside, and stuffed it in while Yin Ruoyue was still awake. into her mouth.

She didn't know if Yin Ruoyue was used to it, but she consciously swallowed the capsule into her stomach just like she swallowed milk last night.

Then Han Chen gently put her aside and covered her with a quilt.

Because the apartment was not far from the company, Han Chen came to the company at [-]:[-].

After Han Chen came to the company, he opened Deep Blue Video to check the playback volume of the mythical TV series.

The Shinhwa TV series has been viewed 2 million times within 1700 days of its release. Because the plot has not yet fully unfolded, Shinhwa's reputation has not yet come out.

As for Shinhwa's entire advertisement, it was taken over by Naice Group. Naice is very willing to spend money on advertising.

Zhang Huajian first contacted P&G, but P&G felt that the price of Shinhwa was too high. Not only did the price of Shinhwa increase by 10 million, but the number of views also dropped from 5 billion to [-] million, so they declined Zhang Huajian.

Zhang Huajian contacted Naais Group immediately. Naais was still hesitant at first.

However, after they watched the Shinhwa TV series, they immediately signed a contract with Zhang Huajian.

At this moment, the door light on the table turned on. Han Chen pressed the switch after seeing the door light turn on. Chang Huazhang opened the door and walked in after seeing the light turn on.

"Mr. Han, Mr. Franz Sachs, the vice president of Qualcomm, would like to make an appointment to meet with you. Do you want to see him?" Chang Huazhang asked.

"Just look at the arrangements for these two days. Just tell me after you make the arrangements." Han Chen said after thinking about it.

Han Chen had already guessed the purpose of Mr. Franz Sachs coming here. He was just here for the patents of Deep Blue Semiconductor, but now Han Chen still planned to meet him first.

After all, people are willing to come all the way here, so how can he be embarrassed not to see them.

"Mr. Han, according to your daily habits, I will arrange it for the afternoon of the day after tomorrow." Chang Huazhang said.

"Yeah." Han Chen nodded.

After Chang Huazhang left, Han Chen immediately immersed himself in learning.

In a coffee shop in Beijing.

A man in a black suit with a tall hairline who looked a bit like Bakujiang opened the door of Box 2 under the guidance of a waiter.

When Yang Bili saw the other party, she immediately stood up and greeted him with a smile.

"Hello, Mr. Hong." Yang Bili greeted with a smile.

Yang Bili is Tong Jingjing's colleague at Worui Headhunting Company, but she has now left Worui Headhunting Company. She is now the general manager of Deep Blue Manpower BJ Company.

The man in front of me who looks like Baojiang is called Hong Feng. He joined Google America in 2005 as a senior software engineer. He is the main person in charge of the Google Calendar and Google Maps 3D Street View projects.

In 2006, he served as senior product manager of Google China, leading the Google China team to launch a music service that combined with Chinese characteristics and created the Chinese business model.

The projects led by Hong Feng at Google China also include Google Chinese Input Method and Google Video.

"Hello, Miss Yang." Hong Feng shook hands with Yang Bili and said with a smile.

After the two sat down, the waiter asked Hong Feng what he wanted to drink. Hong Feng also casually ordered a cup of latte coffee. The other party was able to come to the coffee shop to meet her as requested. The other party had already guessed Yang Bili's purpose, so Yang Bili also I planned to get straight to the point with him.

"Mr. Hong, Deep Blue Group plans to engage in mobile phone business next year, and would like to invite you to join Deep Blue Group as system development director. Your main task is to develop the Android system for the second time. The salary will be increased by 30% based on your current salary." Yang Bili said bluntly.

"Ms. Yang, although Deep Blue Group has become famous recently, Deep Blue's prospects are better than Google's. If it were based on salary alone, I would not consider working at Deep Blue because salary is not my only choice." Hong Feng said.

"I believe Mr. Hong should know that Google has been negotiating with its superiors recently. Mr. Kai-fu Lee's choice to leave Google means that Google will not compromise with its superiors. As expected, Google will withdraw from the Chinese market within half a year, because Chinese law will not be affected by a certain company. And to make a change.

This also means that Mr. Hong will be unemployed within half a year. Although the current Deep Blue Group is not as good as Google, Deep Blue is definitely the fastest growing company in China.

Because Deep Blue Technology has several cash milk products, this also means that Deep Blue will not be affected by funds. Deep Blue is far more stable than you think. It is a stable and promising company, and Deep Blue is still a nascent company.

Mr. Hong, I can't think of a better choice than this. "Yang Bili smiled. (End of chapter)
