After some more temptation, the crowd became more convinced that the sound of tinnitus was made when the iron awl touched the stone saucer!

"What's going on??? "Wan San said in great confusion, meaning that although I had read countless technology magazines, I had never heard of such a thing. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"That's weird enough...... Also, this voice...... Could it really be tinnitus?" Er Lei also said very entangledly, and doubted the classification of this sound.

It is true that as I said before, this sound does sound like the tinnitus, but as I said before, the tinnitus cannot be intermittent.

So......

......

"Hmm, why do I hear this sound like ......" Lao Zhang stopped talking, and motioned for Hachi to touch the iron awl to the stone dish again.

"Well, what is it like? You should tell me quickly...... "The master hurriedly urged.

"Like that...... The blind sound of the telegraph or fax machine ......," said Lao Zhang, thinking about it.

"Well, yes, it's really like a blind sound from some kind of electromagnetic wave......" Chen Fei also said suddenly.

After Lao Zhang said this to Chen Fei, everyone immediately realized! Indeed, although everyone has rarely or never seen the telegraph or fax machine, they have all heard the radio in their lives. Even if you don't have a good time, you have used those headphones, otherwise how to solve the middle school English listening test?

So now, everyone unanimously concluded that this faint sound like tinnitus that surrounded the ears was some kind of signal blindness!

Thinking of this, everyone couldn't help but be overjoyed, and said that they didn't expect the mystery of the sound to be revealed so quickly...... But where did this sound come from, and how could it come from in such a situation?

So to put it bluntly, the mystery of the sound at the moment, I'm afraid it's just begun......

......

"Huh, is it possible...... Is it because it's really high here, and it's made of metal, so it receives the signals of the past by mistake? That is, the sound is transmitted wirelessly...... ...... coming," Erlei said thoughtfully.

Indeed, at this time, Erlei's statement does have some truth in the ears of those who don't understand wireless transmission at all or know a little about it. And, at this time, apart from the wireless transmission, everyone really can't think of any other explanation.

Here, let half a bottle of vinegar Erlei make up for the basic knowledge of wireless transmission for everyone......

......

Wireless transmission, technically called wireless communication.

This wireless communication is a communication method that uses the characteristics of radio signals to propagate in free space for information exchange.

Wireless communication on the move is also commonly known as mobile communication, and people refer to the two together as wireless mobile communication. To put it simply, wireless communication is a communication method that uses only electromagnetic waves and does not pass through cables.

Wireless signals can be sent from one transmitter to many receivers without the need for cables. All wireless signals are transmitted through the air with electromagnetic waves, which are energy waves that are made up of electronic parts and energy parts.

To put it in more detail, the spectrum in wireless communication includes frequencies between 9 khz and 300,000 GHz. Each wireless service is associated with a region of the radio spectrum. The wireless signal also originates from the current transmitted along the conductor, and the electrical signal travels from the transmitter to the antenna, which then emits the signal into the air as a series of electromagnetic waves.

The signal travels through the air until it reaches the target location.

At the target location, another antenna receives the signal, and a receiver converts it back into current. Antennas are required to receive and transmit signals, and antennas are divided into omnidirectional and directional antennas. In the propagation of signals, due to the effects of reflection, diffraction, and scattering, wireless signals will follow many different paths to reach their destination, forming a multipath signal.

Whereas, wireless communication mainly includes microwave communication and satellite communication.

Microwaves are radio waves that travel a distance of only a few tens of kilometers.

Microwave communications require the construction of a microwave relay station every few tens of kilometers.

Satellite communication is the use of communication satellites as relay stations on the ground to establish microwave communication links between two or more earth stations or between moving bodies......

......

Er Lei made up for the knowledge of wireless transmission that he could understand in one go. But at this time, he realized that just now when he was pretending to compare, he forgot to squint his eyes and raise his hands like Wan San.

Gotcha, it's a loss.

However, after his bad remedy, everyone has a general understanding of this so-called wireless transmission.

"Hmm...... That's right, the signal is supposed to be transmitted wirelessly......" The Master nodded affirmatively, as if he really understood.

However, regardless of whether this master really understood at this time, and whether Erlei's knowledge of the wireless transmission was correct or not, one thing was certain, that is, the signal sound at this time was specified to come from this wireless transmission! This is undeniable to anyone, and the reason is very simple, there is indeed no physical line on the entire Iron Palm Peak....... Hi......

......

"But...... Where did this signal come from?" Ye Qiu still wondered. What he means is that, according to the principle of wireless communication, in order to achieve this wireless transmission between the two, there must be the same electromagnetic frequency. But this Dading is not an antenna, so how can there be the so-called electromagnetic frequency?

"...... this?" Er Lei was speechless, because half a bottle of vinegar is half a bottle of vinegar after all.

"Also, in order to achieve this wireless transmission, it is necessary to generate an electric current. But this big tripod ...... It's not electrified, ......?" Ye Qiu continued. Yes, it seems that this kid is well hidden, and he knows more about this wireless transmission than that Erlei.

"...... this?" Er Lei was still speechless, and the reason was still like that.

"Well, could it be because of the lightning ...... just now?" Hachi interjected. What he meant was that it was because of the lightning that had just been that the tripod was electrified.

Everyone shook their heads, which means that although we don't understand this wireless transmission, and we don't understand the problem of electricity, we can be sure that if this Dading had electricity at this time, then you would have become a Jordan by now, at least the same skin color as him......
