Walking on the way to the dormitory, Liu Haiyang turned to look at Atletico Ma and asked, "The richest man in Ma, what did you mean by donating 106 yuan and 5 cents just now?"

"A donation of 100 dollars, to be taken out to 6 of the Red Cross. 5% of the management fee!" Atletico didn't want to say, "I specifically checked the information, according to the regulations of the 14th session of the United Nations General Assembly, the Global Red Cross and Red Crescent Society can withdraw a part of the donation as a management fee for its own operation and the start of the project, called the project support fee, which can be withdrawn up to 6. 5%。 So I consciously added it, saving them from withdrawing a hundred yuan after the donation becomes 93 yuan5 is not neat. ”

"Uh, can you do this?" , the boss opened his mouth wide and asked, "Is there really such a rule?"

Atletico nodded, "Of course." The vast majority of National Societies are civil society organizations that need to take a management fee to pay the salaries of their employees, as well as subsidies and logistics for volunteers. You can't let people come to volunteer and don't even care about a meal, and let them bring their own dry food and five cents, right?

"Not only did I donate this way, but I also asked Jiajia to donate this way, and we also donated this way at Bee. Employees are 10 yuan according to the level level, and then the company adds 6 on the basis of all employees' donations. 5% of the management fee, and finally made up more than 133,600 yuan and made a donation account to the Ludao Red Cross Society. Don't look at the small amount of money, it is because we have few employees, which is already beyond the donation strength of the housing department. ”

Liu Haiyang looked at Atletico Madrid, with an expression on his face that you have betrayed the revolution with thick eyebrows and big eyes, "Who are you not good at, learn from Fang Kewang Shi? They donate an average of 12 yuan for an employee, and you also donate 10 yuan each?"

"It's not one person who donates 10 yuan, but a first-level donation of 10 yuan, like I also donated 130 yuan in the company, which is much more than Lao Wang's donation. Atletico said with a smile.

"That's not right!" Liu Haiyang suddenly remembered that it seemed that the bees had donated a lot of material in kind, and the 130,000 yuan was not as much as the teachers and students of several colleges in the school. It's obviously disgusting, but I don't know if it's a disgusting room or a disgusting Red Society.

"I remember that your official website said that you donated more than 1,000 dragonfly drones, which should be tens of millions, right?"

Atletico said as he walked: "It's good to donate in kind, it is not easy for them to withdraw management fees from the Red Cross Society, and it is not easy to be misappropriated, after all, there are words on it that bees donate to the earthquake-stricken area." ”

This is Liu Shumeng next to him and said, "But you are still a little bit of a child, you see that people Jia Duobao smashed out this 100 million, 'donate 100 million if you want to donate, drink Wang Laoji' A sentence suddenly made their herbal tea from a local drink in the south to a well-known product in the country." This is fame and fortune!"

Regarding the third brother's statement, Atletico Madrid could only shake his head with a wry smile, "Things can't be simply mixed up." ”

"Herbal tea and instant noodles are fast-moving consumer goods, and the price itself is highly competitive, and the price includes one-third of the advertising and marketing costs. From 95 years to 14 years this year, there are 14 CCTV standard kings, and only four times the electronic products are VCD cordless phone repeaters, and the remaining ten times the standard king has three liquor, four drinks, and three P&G shampoos. Biaowang advertising only has ten seconds between the completion of the simulcast and the weather forecast every day, but it costs hundreds of millions a year, JDB spent 300 million last year just to get a live broadcast partner on CCTV Sports Channel, for them, the advertising fee that was originally going to be handed over to the TV station was donated 100 million, and it is very cost-effective and worthwhile to exchange for high-density discussion and recognition of netizens and media across the country. That is to say, the FMCG industry can play like this, but the actions of other FMCG companies have been slowed down, and JDB has stolen the limelight, so they are embarrassed to follow the trend to do this disaster marketing. ”

"Disaster marketing, hey, why does that sound so awkward?" Liu Haiyang chimed in.

"Although it sounds ugly, this kind of marketing and promotion behavior does exist!" Atletico Madrid counted with his left hand, "Wang Laoji's water army and some netizens and fans called on consumers to empty the shelves and support Wang Laoji with actions, which is a typical disaster marketing." Thanks to the earthquake and huge donations, it has gained a high level of attention and reputation, and sales have increased significantly, and it is said that many places are really selling out. Again, after Fang Ke was scolded by netizens for saying that the donation of ten yuan per person was too little, the board of directors immediately unanimously decided to take out 100 million yuan to do public welfare projects in Shu Province, in fact, he also wanted to do disaster marketing, but he did not have the first-mover advantage of Wang Laoji, and the result was still sprayed by netizens. “

"But don't you think it's ridiculous?" Atletico Madrid pointed to the boss Liu Haiyang and the three Liu Shumeng, "Listen to me about the 6 of the Red Cross to withdraw donations." 5% as a management fee to pay your own salary, you find it all kinds of unacceptable, but you agree with the concept that buying Wang Laoji is equivalent to donating. Don't you know that in a 4 yuan jar of Wang Laoji, there will not be more than 1 yuan that can really fall into the hands of JDB? Most of the money has been divided between supermarkets and layers of wholesalers, and JDB cannot really donate all their profits, and what they donated is actually the advertising money that was originally going to be given to the TV station. In this sense, if you spend four yuan to support Wang Laoji, it may end up being equivalent to only a few cents entering the donation channel, and it is better to transfer one dollar directly to the online account of the Red Cross Society. Moreover, the Red Cross Society does not have to mention so much management fees fixedly, this earthquake is all over the country and at home and abroad, as well as those foreign companies and foreign political axes who are forced by the iron rooster list to donate tens of billions, and it is impossible for them to withdraw billions of management fees. After all, they have a limited number of staff and supervisors, and they can't sit in too many cars and sofas. ”

"Similar 'you buy a bottle of water, I'll donate a penny' charity action, a lot of drinks are being carried out, but in the end, the thunder and rain are small. It can only be said that when a disaster actually occurs, not many people think of charity, and this attitude is very abnormal. In fact, Wang Shi is right, doing charity should be a long-term daily routine, and we must do what we can, and we can't turn charitable donations into burdens. For example, Jiajia and I donate 1,000 yuan a month to my mother's water cellar project to repair a water cellar, and now there are more than a dozen. ”

"Pony, you're not authentic!" Liu Shumeng put his arm around Atletico Madrid's shoulders and said: "Just the two of you quietly do good deeds, why don't you bring the third brother and me? If you can't afford to donate a thousand a month, it's still no problem to donate a mouthful a year, if you can do it in installments, it would be better." ”

"Do it, do what you can, charity is not enough, like the kind of behavior that makes oneself poor in order to donate money to education, it is admirable, but it is not worth learning. ”

"Well, yes!" the boss made a final decision: "How big a bowl to eat, how much to eat, in fact, it is more important and practical not to waste it, not to mess around, and not to cause trouble to the country and society." ”

"Gotta got, isn't it just to buy a new mobile phone, as for biting like this?" said Liu Shumeng took out his touch tov8 from his pocket, looked at the time and said: "It's not all to blame the fourth child, your MT mobile phone has jumped again, I've been waiting for a semester and haven't officially launched it, I really thank you for the flowers I waited." ”

"We can't be blamed for this, it's all a problem with our partners, and we can only continue to wait for the food to be cooked if the supply of WAPI chips can't keep up. "Atletico Madrid.

"Others are waiting for the dishes to be cooked, but you are waiting for people to grow vegetables!" Liu Shumeng said with hatred: "Anyway, the WAPI Alliance is too pitiful, right? From 03 years to be set up as a national standard, it has not been officially industrialized for 5 years now. Always saying that it is about to be industrialized and about to go public, but you only hear the sound of the stairs and no one comes down, you should have given up a long time ago. ”

"We used to sit on a copycat solution, regardless of the problem of illegal wifi. The result is that I am now ready to make a mobile phone, only to find that I can't use wifi. At that time, it was either like other mobile phone manufacturers to directly remove the wifi and use Bluetooth, or wait for WAPI to be mass-produced and listed, and the result was hehe...... These people have not yet made money, so they have started a fight for the issue of sharing money!"

"Are you still waiting for Vantone and Huada to launch mass production chips?" Although he has given up waiting for the Bee MT mobile phone, Liu Shumeng is still very concerned about the recent situation of the Bee mobile phone.

"Don't wait. We plan to officially release the first Sunflower Sunflower phone at CJ this year. Atletico shook his hand, "In fact, we had three preparations, MT1 is a WAPI solution, MT2 is a WiFi solution, waiting for the country to lift the ban or take the export route, and MT3, the development of a new technology to replace the wireless LAN." ”

"Develop new technology, do it yourself?" Liu Shumeng was obviously surprised by Atletico Madrid's statement and decision, so much so that he almost tripped and fell on the stairs under his mental loss.

Fortunately, even if Atletico reached out and grabbed his arm, he himself reached out and propped himself up on the ground, so he didn't really bend his knees on the stairs.

Shocked for a while, Liu Shumeng took out a wet towel and wiped his palms and asked: "Xidian, Wantong These companies develop WAPI on the basis of WiFi, and the others don't move, just change the encryption algorithm and spend tens of millions, and now I don't see any hope of recovering the cost, you bees are so rich that you can afford to burn this money?"

"Who made them have only turtles and doctors, and no openers like me. Ma Jing slapped himself twice on the chest and said with a smug face.

"Yes, yes, you're an open-minded person, you're a genius, you're a superman, right? God-level genius Superman classmate, can you tell us mortals about your thinking, so that when we go out, we can brag to others: we also lived in a dormitory with the richest man back then!"

"We don't have the same ambition as the WAPI Alliance, as long as the basic usability is not too expensive. If it weren't for Bluetooth 2. 1. Although the standard is there, but the chip has not yet been listed, maybe we will give up independent research and development and directly use the new generation of Bluetooth chips. Atletico first said: "In fact, there is nothing new under the sun, many technologies have already had prototypes and concepts, and the same is true of our sunflower plan." And because the MT3 solution is the first mobile phone equipped with a visible light communication solution, we simply named it Sunflower in Chinese. ”

"Optical communication route?" Liu Haiyang frowned and asked, "VLC technology has not been out of the laboratory for more than ten years, and you have solved all its problems?"

"I solved a part of it, and it basically worked. Atletico said.

VLC is the abbreviation of visible light communication (VI private ble-light-munication), as early as 2000, Keio University (Keio) and Sony Institute of Computer Science in Japan opened up the research direction of using visible light for data transmission. Subsequently, a number of Japanese and Korean electronics and communication companies such as Casio, NEC, Panasonic, Samsung, Sharp, Toshiba and NTTDOO jointly established the Visible Light Communication Alliance to promote IEEE802. 15 wireless personal LAN standards committee added". 7" working group, with a view to elevating visible light communication to an equal footing with infrared communication and wireless communication.

"In VLC, our country is also catching up with the international trend and is not too far behind. The year before last, a university made a transmission level of 20 centimeters, and now two years have passed, both the bandwidth and the communication distance should be greatly improved. We don't have the technology to use them, though. ”

VLC visible light communication is simply to use the lighting bulb as a communication device, the light of the bulb represents "1", the off represents "0", by adjusting the frequency of millions of times per second can transmit data signals, so that as long as there is light, there is a network and there is a signal.

It sounds like a cool futuristic technology, but it's hard to put into practice. First of all, the problem of light bulbs, traditional incandescent lamps and fluorescent lamps cannot achieve a high frequency of light and off changes due to the principle, only LED lamps can achieve this function. Even LED lights, limited by the life of the bulb, millions or even tens of millions of times per second (10MHz) are basically to the limit, and any more may lead to the life of the bulb being too shortened and losing its practical value.

And the common carrier frequency of wifi is 2. 4GHz and 5GHz, the two I** engineering and medical frequency bands, theoretically the higher the frequency, the more signals can be carried, and the greater the bandwidth provided. However, the result of too high a frequency is that the wavelength is too small, so that the more directional the electromagnetic wave is, it will eventually become a branch propagation like visible light, so 802 with a frequency of 5 GHz is used. Although the 11a protocol is faster, it is not as good as practical2. 4Ghz 11b as well as Improver 11g are widely used.

In fact, in the final analysis, VLC is to remove the optical fiber of optical fiber communication and let the data communication between two light-emitting diodes be carried out directly. There is nothing new in principle, but this saving brings great technical difficulties.

The optical fiber uses the refraction phenomenon to bind the laser signal inside the optical fiber, so that the laser that travels in a straight line can be repeatedly refracted and reflected in it, and is not afraid of the bending of the optical fiber, and the visible light communication takes off the optical fiber, which naturally does not have this benefit, and blocking the receiver with your hand, leaving the specific light irradiation range or walking into the shadow may lead to unstable communication or even interruption.

Moreover, the optical fiber not only binds the laser signal, but also blocks the signal emitted by other light sources, so that the laser signal can get a high signal-to-noise ratio, and the higher the signal-to-noise ratio, the higher the recognition of the signal, the less likely it is to lose the information. Visible light communication not only faces the interference of other indoor light sources, but also faces the interference of the bright sun during the day, which is the most fatal.

The sun's warm white light is not a mixture of red, green, and blue, but a mixture of more colors, depending on the elements of the sun. Each element atom will emit several different frequencies of light due to the different movements of their outer electrons at high temperatures, which is the so-called elemental spectrum, and the solar spectrum is the mixture of the elemental spectrum of various elements in the sun, which is not pure white.

"The current VLC communication technology is still very rudimentary, and the bandwidth is completely incomparable with WiFi, even if it barely reaches the Bluetooth level, but the effective distance is shorter than Bluetooth, and basically it is still impossible to get out of the laboratory. Our sunflower solution combines technologies from other technical fields to create a whole. For example, PLC technology for power line communication, as well as 11G OFDM orthogonal frequency division multiplexing, as well as multiple-input multiple-output, and even CDMA code division multiple access. The existence of these off-the-shelf technologies has made our chip design work go smoothly and we have now started to tape out. As he spoke, Atletico opened his drawer and took out a box from it.

"This is the Sunflower phone," he said as he unpacked the box, "They sent me a sample at noon today, and I was dragged by you to the donation party before I could even see it." Haha, boss, third brother, you can also boast to others in the future that you are the first people in the world to see a real practical VLC Internet mobile phone. ”

"Wait a minute," Liu Haiyang raised his left hand and asked, "How many people are in this first batch?"

"Well, two or three hundred, if you count the number of MT mobile phones in other schemes, it will be even more. ”

The front of the white cardboard box is printed with a huge sunflower flower pattern, and on the outer tongue-shaped petals lies a blue and white bee, which is the bee's logo and mascot. There is also black text on the side of the bee phone Sunflower 1.

Removing the paper cover on it, the three of them saw an orange straight mobile phone lying in the box, as well as orange in-ear earbuds and orange data cables in transparent plastic bags, but what attracted Liu Shumeng and Liu Haiyang's attention the most were the three smaller plastic objects with colored patterns printed on a white background inside the box.

All three of these small devices have two-pin plugs on them, and it looks like they are all plugged into the mains outlet.

Atletico picked up one with a USB interface on it and said, "This is a special power adapter, which can charge the mobile phone with 5V DC power output at the same time, and also has the functions of power cat and USB Internet access, and can be used to access the Internet on a data line in the case of failure of light communication." ”

"Then these two should be the VLC communication terminal that the power cat and you said, right?" Liu Shumeng picked up one and asked, "Hey!

"There's no way, the integration is not enough, so we can only make up for it with volume. Atletico nodded, "You take the RJ45 network port on it, it is the power cat, it modulates the network signal into the dormitory power grid, and the power cat function integrated on the other two devices reads out the network signal." ”

As he spoke, he picked up the third one and pointed the side where the ten bulbs were installed towards Liu Shumeng, "This is the light cat or light router, one of the so many light bulbs is to increase the bandwidth, and the other is to expand the irradiation range and enhance the signal strength." ”

"I understand this, the principle of shadowless lamp, this middle school physics textbook has been specially taught, and I am very impressed. Liu Shumeng shook the electric cat in his hand, looked down at the bottom of the table at Atletico Madrid, and said, "Come on, hurry up and try it, it's a mule or a horse coming out to slip!"
