Rebirth of Fortune Soars

Cable Broadband?

In addition to transmitting TV signals, this can also transmit network data?

"Yes, cable loan!" Qin Feng nodded, "The cable TV signal line is a cable, and it can transmit signals!"

"So have you successfully developed this technology?" the TV station director asked.

Lei Jun was about to speak, but was stopped by Qin Feng.

"The technology has been successfully developed. Currently, we are at the leading international level with this technology. Only the United States has better technology than ours! Other countries do not have such professional technology! And if we use wired broadband to access the Internet, our The Internet speed will reach the international leading level!" Qin Feng said with confidence.

Lei Jun on the side was almost shocked. This technology is still only in Qin Feng's mouth. Jiang Yong is still relatively confused about the research and development of this technology.

Although it is true that wired broadband can be used for network data transmission, there are technical barriers in this regard. This also requires research and development, and the manufacturing and production of related equipment. Especially in terms of technical protocols, this requires a breakthrough.

Now there is nothing, Qin Feng boldly slaps his chest and promises, what if this can't be done?

"Is this expensive?" the director asked.

"In terms of technology, our company can provide it for free. As for the Internet equipment, it is purchased by Internet users and has nothing to do with the TV station. What the TV station needs to charge is the network service fee related to Internet access!" Qin Feng said, "And this is not just for Anyone in colleges and universities, including the whole city, who have cable TV installed can access the Internet!”

Qin Feng's eyes suddenly lit up. If we can get this wired broadband on our side, it may be able to greatly improve the domestic Internet access process.

After all, nowadays, access to the Internet is limited to telephone lines, which are not only expensive but also slow. But wired broadband is high speed.

At present, the fastest telephone line on the market for Internet access, the fastest is 64K, which is already very few. Most are not that fast.

Mostly 28K and 56K.

However, there is wired broadband technology, which separates a 6MHZ channel from the TV channels between 42MHZ and 750MHZ for downlink transmission of data. Usually the downlink data adopts 64QAM (quadrature amplitude modulation) modulation method, and the maximum rate can reach 27Mbps. If 256QAM is used, the maximum rate can reach 36Mbps. Uplink data is generally transmitted through a spectrum between 5 and 42 MHZ. In order to effectively suppress the accumulation of uplink noise, QPSK modulation is generally used. QPSK is more suitable for noise environments than 64QAM, but the rate is lower. The uplink rate can reach up to 10Mbps.

This speed is definitely not as fast as that of later generations. After all, in later generations, wired broadband Internet access was later abandoned. Because the speed is too slow.

In later generations, there will be 100M optical fiber, or even 200M. That speed, just now.

But now, at least in the next ten years, the speed of cable TV Internet access is sufficient to meet most needs.

If the whole country uses wired Internet access, then network development will usher in a golden period. China's Internet environment will usher in its heyday ahead of schedule.

And he will promote China's network development.

If this is the case, then... Qin Feng feels that he will earn incredible wealth.

Although smartphones have not yet become popular, this is difficult to overcome in the short term. But all kinds of things on the Internet can be found.

For example, chat tools, video tools, download tools, etc., as well as online shopping, online services, etc. These can all be done.

In this regard, I can completely unify myself. Get it out. By then, once the smartphones explode, your company will rule the entire China and even the world.

Thinking of this, Qin Feng became excited.

"Then what do you think the fee is appropriate?" the station director asked.

"Well, I think the initial stage is to seize the market and make it cheaper. After all, these equipment are a one-time investment.

All that will follow is proper maintenance. Usually it mainly consumes electricity. "Qin Feng said.

Later, the director asked some more detailed questions. Of course, these detailed issues are purely technical and have nothing to do with it.

After all, the station director doesn’t understand either. All I can do is ask questions like balance of payments.

"Okay, if the technology is feasible, then we can cooperate with you!!!" The station director nodded in agreement.

After all, with the mayor as his companion, as well as the presidents of Tsinghua University, Peking University, and the Conservatory of Music, he would naturally agree.

Especially, this sounds like a good thing. Then of course there will be no problem.

In this case, he will naturally agree.

"Thank you, Director! I believe you will feel lucky for this cooperation in the future. This is one of the most correct cooperations!" Qin Feng smiled.

"You are quite confident, kid. Let's wait and see!" the mayor laughed.

Afterwards, Qin Feng and Lei Jun said goodbye to everyone and returned to the company.

"Qin Feng, we haven't even scratched the surface of this technology yet. Where did you get it from?" Lei Jun asked anxiously.

"Yes, we have been thinking about this technology for a long time and have no clue at all! We don't know where to get it!" Jiang Yong also looked distressed.

Some things cannot be thought of just by thinking about them. After all, this is something created from nothing. How do you do it?

"I know, but the United States has already developed it!" Qin Fengxiao said, "Time Warner Company in the United States has developed this technology. They use a hardware device called CableModem for data transmission."

CableModem, also known as cable modem. Different from traditional models, this cable modem integrates the functions of MODEM, tuner, encryption/decryption device, bridge, network interface card, virtual agent and Ethernet hub. It does not require dial-up Internet access, does not occupy phone lines, and can provide a permanent connection that is online at any time. A VPN (virtual private network) connection is established between the service provider's equipment and the user's Modem, providing a standard 10BaseT Ethernet interface to connect to the user's PC equipment or LAN hub.

"How do you know so clearly?" Everyone gasped.

"Have you forgotten that I am also a college student in the IT Department of Tsinghua University?" Qin Feng glared, "Besides, I have been to the United States several times."

Everyone was stunned.

"But even if we know it, we don't understand it! And if we buy this equipment, we may not be able to copy it!" Jiang Yong asked.

"Don't worry. It's May Day soon. I'm going to fly to the United States to visit Time Warner to see if we can introduce this technology!" Qin Feng said, "If it can, it will be simple."

"Will they sell it?" Lei Jun frowned.

"Don't worry, as long as you make money, there's nothing you can't buy! Besides, I won't go there with my identity!" Qin Feng smiled lightly.
