Chapter 529: Radio Waves

Ye Tao nodded to the two technicians in standard overalls, and after opening these wooden boxes, and pulling out the fillers such as cotton wool and paper strips used to absorb the impact, the true face of the goods was revealed. There were three boxes containing seven tin boxes, large and small, as well as a bunch of wires and metal bars. The technicians skillfully installed the entire set of equipment, while Ye Tao explained to Tan Weiran and Chi Lei on the side.

"This is a wireless telegraph that has not yet been fully finalized. In fact, the telegraph transmission and reception test has not been carried out over such a long distance, especially since there are various terrains in between. The farthest distance we did seemed to be from Gondor to Wind Tracer, and the straight-line distance measured on the map was 3,320 li, but from Gondor to Tianmeng City, I am afraid it was more than 4,000 li. Between Gondor and Wind Tracing City, because there are no mineral deposits, and the interference is relatively small, I don't know if it is easy to use when it comes to your side. I hope it works, but it's just a test. Ye Tao told me that when it came to these technical things, the confidence and unquestionable confidence he showed would always exceed his level as a strategic envoy of Northern Xinjiang. It is only on this occasion, which is becoming less and less common now, that they, old friends who have known Ye Tao for many years, can confirm from the bottom of their hearts that Ye Tao has never changed.

"You mean...... Can we telegraph directly to Gondor in Tenmon? This...... It's incredible. Chi Lei stammered to confirm.

"Yes, theoretically. Actually...... We'll have to wait for the results of the test. Ye Tao nodded.

"If you can really telegraph directly with Gondor...... If this thing could be a little smaller, if there could be one in each battalion, then the way of fighting would have to change drastically. Tan Weiran groaned slightly, and discovered the meaning of wireless telegraphy.

"Yes," Ye Tao said, "This is now one of Dongping's top secrets. If you succeed in the test here, you'll ship four or five more to this side. Several wireless telegraph stations can communicate with each other. ”

Radiocommunication was developed almost as soon as the wired telegraph was first introduced. But now, with the popularization of the cable telegraph network, as the telegraph stations began to penetrate into the smaller and smaller administrative units of Dongping, it is not an exaggeration to say that the telegraph has changed the lives of the people of Dongping. Dongping's rule over the localities also became more centralized and efficient with the spread of the telegraph network. Now, if there is any trouble, as long as a telegram is sent to Danyang, you can quickly get instructions from the imperial court. Whether in civil affairs or military, the central government's control over the entire country has never been stronger, and its authority is heavier. And after this benefit gradually became apparent, Chunnan now wants to popularize the telegraph network, instead of having telegraph stations only in a few metropolises in Chunnam as it is now.

Many people do not understand, since there is already such a powerful cable telegraph network, what else do you need to do with wireless telegraphy? The more they came to this time, in the face of the respectful incomprehension of others, the more Ye Tao and Tan Weixin felt how valuable it was for the two to communicate with each other, they had long been tired of playing prophetic characters, and they had been effectively changing this era. However, there are some things that can never be achieved easily. For example, in the field of wireless communication, what they see is that in I don't know how many years later, something as cumbersome and inefficient as the telegraph will definitely be replaced, there will be something like walkie-talkies, and in the future that they should not have time to see, there should be more interesting and fun means of wireless communication, maybe the mobile phone they are familiar with? But all of this is based on the fact that people in this era must be proficient in the technology of microwave carrier transmission signals, and they must be able to unswervingly persist in the field of electronics......

The wireless telegraph was basically the product of Ye Tao's insistence, but when the first test model was trial-produced, Tan Xiaopei was shocked, he went to Gondor in person, and then went to the Ye's Workshop Research Institute, where he personally verified that the wireless telegraph machine could communicate at three distances of 20 miles, 100 miles, and 200 miles. Later, when the communication distance of wireless telegraphy reached 1,000 miles, he ordered 25 units to equip the main armies of Dongping. And this time, the telegraph brought to the northeastern border is the latest model.

However, the reliability of today's telegraphs is still somewhat reduced because the distance is too long. Therefore, it is estimated that it is necessary to take multiple repeated transmissions for verification to ensure that there will be no sending errors. In particular, sending a relatively long message may require a day or two of continuous verification, but even if it is, it is much faster than our original method. ”

"It's natural...... I really didn't expect it...... In the past, the so-called military situation was just a matter of thinking, but I didn't expect it, but now it can really be done. Tan Weiran sighed.

Originally, in terms of operational command, it would only take three or four hundred miles of wireless telegraphy to convey military orders. But once the territory expands to a certain point, it is a completely different situation, and a wireless telegraph may be an important strategic resource to completely control a piece of land. Dongping, now there are two unbordering lands in Tianmeng City and Yazhou, and in the future, I am afraid there will be more such places. The lack of reliable communication is very disturbing. As for the question of reliability, we can only wait for the improvement from generation to generation. Ye Tao continued to explain: "Now this kind of wireless telegraph, only three have been trial-produced, one is in Danyang, one is being installed in Gondor, and there is this one, go back, and after a few more trial-production, you will try to set up a relay communication station somewhere on the sea, Yicheng and Zhenningguan will also be installed, and then your communication will not have to rely on one-to-one telegraph for repeated verification." A few messages to make do, how do you know what you're talking about. ”

Ye Tao ran away to Tianmeng City? This is by no means good news for Beiliao. For many years, the deployment of assassinating Ye Tao, Tan Weixin and others has never been interrupted, but it is indeed difficult to succeed. And in Tianmeng City, although it is said to be a place closer to the Northern Liao forces, no one who really understands the battle situation here will do this kind of useless work. Northern Liao himself pushed himself into a situation where he did not share the sky with the tribe, and he had never selected and cultivated any secret spies among the tribes. The people in their own hands are too far apart from the people on the tribe's side, their image and appearance, and so on. The strange local words of the tribe can make any spy collapse. Now Beiliao is in several hidden places not far from Tianmeng City, and there are indeed more than a dozen capable scouts, and their skills are also good, but it is absolutely wishful thinking to want to sneak into Tianmeng City, which is full of tribes and Dongping people.

Ye Tao stayed in Jiamen Town for more than a day, and then went to Tianmeng City. Tianmeng City is probably the fastest-built, but also the most expensive city ever. After the site selection, only a few large brick kilns were built nearby to provide bricks and stones for auxiliary positions in urban construction, and most of the other materials were shipped from Yicheng and then all the way from the port. Considering that Tianmeng City is an important fortress city and the convenience of transportation, the bricks of the city wall are completely made of the latest research of the master's workshop, and the special city wall bricks called "King Kong bricks". The density of this kind of brick is not much different from the red bricks used in ordinary people's homes, but the hardness is only slightly inferior to that of natural rock. The success of the research and development of this kind of brick has made the Shijia extremely excited, and the Shijia has been closely following the footsteps of Ye's Workshop since the early years, and has spared no effort in the training of various technicians. The brick kiln of the Shijia family was established in the second year when they cooperated with the Ye family and began to participate in the assessment of the craftsmen of the Ye Workshop, and originally wanted to take advantage of the vigorous development of the Ye Workshop, especially the Ye Construction Bank can always receive the best projects, they want to rely on their familiar faces, so as to make a small fortune and become an excellent supplier for many years. General brick and tile materials, naturally it is not worth Yip's Construction Bank not to use the materials produced by the local brick kiln to use their products, but the division has taken three years to become the best supplier of glazed tiles, hollow bricks, refractory bricks, hard turns, corrosion resistance and water erosion resistant materials in the country. The construction of Gangduo and Danyang relied on the brick kilns of the Shijia family. In the early years, the Shi family relied on Ye Tao to provide glazed tiles and hollow bricks, but gradually, their accumulation of technology in this area has made Ye Tao a little dumbfounded. Shijia now has the most comprehensive sample library of all kinds of soil and stone materials from all over the country, has a complete set of logistics system that can transport heavy and extremely large quantities of bricks to the whole country, and has 1,700 brick kilns large and small for the production of brick and tile materials of various sizes...... King Kong bricks, perhaps just this kind of long-term accumulation, the most normal outbreak. And after the birth of this material, the order from the Dongping Imperial Court alone was enough for the master to work for three or five years. It is precisely because of this material with the right hardness and density that Tianmeng City can have a large scale in just a few months.

Tianmeng City was built in a very special way, and it will eventually become a regular octagonal Tianmeng City, with a five-story turret at eight vertices first, and then a section of the wall between the turrets. After that, there are the various facilities within the city. It was Zhao Dazhu who did the design of Tianmeng City, Zhao Dazhu, who was so exquisite that it was incredible, although in terms of the aesthetic planning of the city, it was probably the worst among several brothers, Tianmeng City was the first time he was involved in such a large-scale construction project, but his ideas were very simple and practical. After the entire Tianmeng City is established, even down to the last turret, it will be able to form a posture of continuous resistance, and it will not fall as a whole because of the fall of one city gate or one part. But when considering the need to fight and construct at the same time, Zhao Dazhu had to leave the sewer system, which has now become the norm for the new city, to be carried out after the exterior wall was completed. By the time Ye Tao arrived, six of the eight turrets had been completed, while the city walls and gates facing the Northern Liao side had already been completed in advance. Once it encounters an attack from the Northern Liao, Tianmeng City may only be able to defend itself as a fortress group rather than a city, but now, the Northern Liao may not have much chance.
