    After listening to Frank Kent's introduction, Qin Shiou still didn't understand the working principle of the so-called tetra, but it didn't matter. It was just like North American slang: If you want to eat a chicken, then just go and eat it. You don't have to understand it.  How to do it.

    Qin Shiou needs a radio base station, but not a cluster radio for walkie-talkies, but a high-power communication system for the airport tower.

    He told Frank about his goal, and Frank said happily: "That's no problem. Civilian private airports only need a 100m power communication base station, which costs about 100,000 yuan."

    The price is not expensive. Qin Shiou settled it directly with Frank. There was no need to choose between left and right. Motorola is still very prestigious in the wireless field.

    Listening to the discussion between Qin Shiou and Frank, Hamre rolled his eyes, twitched the corners of his mouth with a smile, and then said: "Qin, don't you plan to build a tetra digital time division multiple access base station?"

    "It's no use to me."

    "No, no, buddy, of course it works. You see your fishing ground is so big, when you produce fish, there must be multiple fishing boats working together. Do you plan to use mobile phones to communicate by then? The signal at sea is not good."

    Hearing what Hamre said, Qin Shiou felt it made sense.

    Farewell Town has its own mobile communication base station, but it is not very powerful. Qin Shiou¡¯s mobile phone signal is not up to standard all year round. Once it is windy or rainy, the signal gets worse, so he can only use wifi to access the Internet at home.

    "It makes sense, but what is the radiation range of the cluster base station? I think if a base station is built on the island, it won't have much effect, right?" Qin Shiou asked doubtfully.

    Frank said: "Yes, sir, if you only build one base station on the island, the radiation range will extend to at most twenty kilometers in the ocean. However, if you build a communication cluster on the island, and then install a shipboard  Terminal, the radiation range can reach four hundred kilometers into the ocean!"

    "So domineering?" Qin Shiou asked in surprise. Frank silently felt the distance of four hundred kilometers and couldn't help but nod.

    "If your tetra system is so powerful, why not promote it to the civilian market? A communication distance of four hundred kilometers is very tempting for home communication, right?" Qin Shiou asked strangely.

    Frank smiled bitterly and said: "That won't work, sir, that's useless. Our tetra requires the base station host and the base station terminal to be used together. Whether it is the host or the terminal, the size and weight are too large and cannot be used in the car. Besides, who  Do you like carrying a heavy walkie-talkie around a lot?"

    Qin Shiou thinks about it. Mobile communication costs in Canada and the United States are relatively low, and ordinary calls at night and weekends don't even cost money.

    Seeing that Qin Shiou is interested in building a cluster base station, Frank perks up. A cluster base station cannot be built for tens of thousands of dollars. If he can win a customer, the bonus alone will be more than his monthly salary.

    So, he took out the map of Farewell Island and showed it to Qin Shiou: "Look, the shape of your island is a very uniform oval, and there is Mount Kanbar in the northeast. The base station host is built on the mountain peak, so the radiation range can be wider."

    "My suggestion is that you can build a cluster of four base stations across the island, with the Kanbar base station as the first host, according to the 800m tetra, and the others can use 400m. In this way, the ocean around the island is yours.  communications territory.¡±

    "If you want to build a four-connection cluster, it can be done for about 500,000 yuan."

    Five hundred thousand, Qin Shiou thought for a while and was about to nod, when Hamre put his arm around his shoulders and said with a sly look: "Don't make a decision in a hurry, Qin, I said you have no problem building a base station, can you let us suppress it?"  Do you want the people to take advantage of it?"

    When Hamre said this, Qin Shiou understood what this guy meant. He wanted him to open the cluster wireless channel, so that as long as he had the password, the townspeople could buy a walkie-talkie and talk to each other for free.

    ¡°More than that, many things have become easier with radios. For example, when a tour guide leads a group to climb Mount Kanbar, there is no signal in the mountain, so every time tourists enter the mountain, extra manpower must be provided to prevent accidents.

    With radios that can radiate throughout the island, and allowing each tourist to bring a walkie-talkie into the mountains, there is nothing to fear. Even if tourists leave the group and get lost in the mountains, they can still be found.

    Qin Shiou is not a stingy person, and it is okay to let the townspeople take advantage of him, but he must first ask clearly: "After forming a radio cluster, how many people can use it at most?"

    "You mean how many private terminals can be connected?" Frank asked, "You don't have to worry about this. Tetra uses digital time division multiple access technology. Its systemThe system function is more powerful, the communication quality is more excellent, the confidentiality performance is better, and the frequency resources are used more effectively"

    "Dude, don't talk nonsense, okay?"

    "Sorry sir, I'm used to it. Okay, let me introduce it. Our tetra system-dimetra is currently the world's most technologically advanced and most productized digital trunking communication system. In terms of transmission methods, it can not only provide  "One-to-one" full-duplex cellular phone service can also perform fast "one-to-many" team scheduling communication. After a cluster is built, 16 channels can be opened, enough for 1,600 private terminals to access." Frank introduced  road.

    "It's definitely enough." Hamre said with a smile.

    Qin Shiou shrugged, "I haven't agreed yet, man!"

    "Oh, don't be like this, my man, you will agree, won't you? In fact, if we can enjoy your channel, it will also be helpful to the fishery. If you have any questions, just shout on the public channel, then the whole town will know, and no one will come to find you  If you are troublesome, we can help you as soon as possible," Hamre said.

    Politicians are politicians. Qin Shiou heard that this was true. His base station cluster was equivalent to connecting every household in the town to a network. Whoever was in trouble was just a matter of words.

    Thinking of this, he naturally had nothing to say, OK, let¡¯s build it, then build a base station cluster.

    "We can also help you on the public channel with advice on how to capture the Jiadeli Fishing Ground." Hamre was afraid that Qin Shiou would not be willing, so he continued to raise tempting topics.

    But this is a trivial matter to Qin Shiou. He waved his hand and said, "Just leave the Jiadeli Fishing Ground to me. I can handle it."

    Qin Shiou decided to build a base station, so Frank didn't leave. He called the company and delivered the machine directly to Farewell Island.

    Driving home, Qin Shiou went to take a hot spring bath in the afternoon.

    The hot spring has not been expanded yet and has an original ecological smell. After the hot spring was dug for a period of time, sulfur steam continued to surge upwards, and the surrounding stones were slightly yellow with a faint smell of sulfur.

    Qin Shiou put a deck chair in the water and lay down on it. Well, the water was slightly hot and it was comfortable.

    Du Lele was not as good as Zhonglele. Qin Shiou beckoned to Huzi Leopard. The two little guys jumped to him and followed him on the lounge chair.

    When Xiong Da saw them entering the water, he immediately became curious and jumped towards Qin Shiou with his fat butt.

    "Fuck, no!" Qin Shiou screamed!  (Remember the website address: www.hlnovel.com
