According to Duke's understanding of existing earth communication technology, except for satellite communication, only microwave communication can achieve the ultra-long-distance wireless technology of point-to-point data transmission.

However, if he does not return all the knowledge he has learned in the school to the teacher, it seems that the maximum practical transmission distance of a point-to-point microwave device is within 50 kilometers, and at this limit distance, it must be unblocked. Even so, in this limit state, the data transmission is not very stable.

But the microwave still has the disadvantages of being unable to cross and bypassing large buildings. From Duke's home to Bileme, there is not a plain in the middle where there is no obstacle. Although Duke's villa is outside Chengdu, you can vaguely see the peaks on the other side of Xiling when the weather is good.

However, there are many high-rise buildings in the middle, not to mention that the mountain is still in its original state. Bileme's alien mothership is covered by towering trees. Obviously, it is difficult to complete under this situation if microwave method is used.

Duke couldn't help but be curious and expectant about Lyme's remote wireless access technology.

Bileme's concept of time is still relatively strong. Soon, Duke received Bileme's new communication equipment design plan.

"This is a design I made on the spot. It may be a bit simple, but it's enough to use it." Bileme said after passing on the design plan. "The technology and components used are selected based on the basics of your existing wireless communication equipment on earth. You should be able to easily understand this thing and easily find the components that implement this thing for assembly."

Duke couldn't help but burst into tears when he heard Bileme say this. Bileme was finally able to provide something that could be used directly without worrying about himself.

Open the solution, with Duke's current communication technology foundation, this design does not look particularly complicated, and it tastes like a mixture of two current mainstream wireless communication technology, Wimax and LTE. So this is an improved solution for the existing wireless transmission technology on the earth. There is nothing particularly surprising in terms of transmission speed. It can provide about 100 megabytes per second transmission capability on a very narrow communication frequency band.

However, Bileme uses a genius and creative modem algorithm to perfectly filter out background noise under low bandwidth signals, and thus obtain excellent transmission distances. According to Bileme's existing instructions, Bileme's wireless communication device can send signals to more than 100 kilometers at a power of several watts, which means that the remote transmission distance can reach hundreds of kilometers.

This transmission distance is beyond the reach of two current mainstream wireless communication technologies, Wimax and LTE.

In addition, this technology has a higher utilization efficiency for communication channels, which can be said to be technically surpassing Wimax and LTE. It is indeed a treasure. Duke couldn't help but feel ecstatic when he saw this. With this thing, the future New Nokia Mobile will be able to use this technology to enter the wireless communication system and equipment market and rewrite the world communication market standards after getting rid of the 5-year protocol restrictions in the future.

However, Duke's joy did not last long, because he soon discovered that the design of Lime was a little too simple, and it only provided something as simple as a circuit design drawing and a modem algorithm. Judging from the circuit design drawing, how did Duke feel that after those familiar circuit designs, he felt a familiar feeling.

Duke has even seen many things elsewhere, so this communication device is undoubtedly designed using some ready-made things on the earth. However, it is precisely because of so many circuits that Duke is familiar with that Duke has the idea that this thing is pieced together.

In fact, this is exactly what Bileme used the earth's communication technology he learned to temporarily piece together, but he borrowed some of his own planet's realization ideas in terms of modem and demodulation. During this long period, Bileme not only went online to exchange knowledge about the universe and starry sky with fans, but also learned some scientific and technological knowledge on the earth through the Internet. Now, at least in terms of communication technology, it is no less than that of a master's student in a regular communication major.

However, the design handed over to Duke is really at the level of graduate students. Duke will soon suffer for a poor design of Bilme.

Duke took Bileme's design and spent two days to understand it. Although Duke had reservations about Bileme's design, based on Bileme's consistent trust and the extremely huge halo of alien technology, Duke did not dare to question Bileme's design, but decomposed it into a circuit board design and component list.

Bileme's design seems to be more complicated than a mobile phone, but the difference is not particularly big. Duke believes that if there is a suitable circuit board, he can realize this long-distance wireless transmission device himself. This thing is related to Bileme's big secret. Duke decided to do it himself and create it himself.

There is nothing to keep in mind about Duke's circuit board, so it is handed over to the sal hardware research laboratory to realize it. Now Rongcheng is almost the base camp for sal research and development, and has built various communications research and development laboratories that can be regarded as first-class in the world. It is not difficult to make such circuit boards designed by Lyme.

To be on the safe side, Duke asked the hardware research laboratory to provide ten circuit boards and ten sets of components in one go. Duke was worried that his welding skills would not be up to standard, so he deliberately made a few more for backup. Soon, Duke was glad that his decision was so wise.

There are indeed not many of the components that Duke needs, and there are a lot of stocks in the warehouse of the SAL hardware laboratory. So the next day Duke got what he needed, then found a laboratory to lock it up, and started doing the work he used to do.

Although Cai Siqiang was a little surprised why Duke was coming back to deal with mobile phone traffic issues, he went to the laboratory at this time, but Duke used to do such inexplicable things, and most of them were eager to study and verify after having some strange ideas.

And usually after this, Duke will produce a new result.

Of course, the idea of ​​genius is not something that ordinary people can guess. Moreover, in Cai Siqiang's opinion, that traffic issue is indeed not a big problem. As long as Duke does not mention it being leaked, what is it worth spending a little more traffic fee?

In Cai Siqiang's opinion, the reason why Duke rushed back was probably because he was worried that something had been leaked, so he would be relieved to come back and check it out.
