After listening to Frank Kent's introduction, Qin Shiou still didn't understand how the so-called tetra works, but it doesn't matter, just like the North American slang: if you want to eat a chicken, then you go for it, you don't have to figure out how to do it.

Qin Shiou needed a radio base station, but instead of this kind of cluster radio for walkie-talkies, he installed a high-power communication system for the airport tower.

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

The price is not expensive, Qin Shiou directly finalized it with Frank, there is no need to pick and choose, Motorola is still very prestigious in the wireless field.

Hamlet listened to Qin Shiou and Frank's discussion, his eyes rolled, the corners of his mouth twitched to reveal a smile, and then said, "Qin, aren't you going to get a tetra digital time division multiple access base station?" ”

"I want it useless."

"No, no, man, of course it works. You see that your fishing grounds are so big, when you produce fish, there must be multiple fishing boats working together. Are you going to use your mobile phone to communicate then? The signal at sea is not good. ”

Hearing Hamlet say this, Qin Shiou felt that it made sense.

Farewell Town has its own mobile communication base station, but the power is not large, Qin Shiou's mobile phone signal is not up to standard all year round, once it is windy and rainy, the signal is worse, he can only use wifi to surf the Internet at home.

"It makes sense, but how much is the radiation range of the cluster base station, I think if a base station is built on the island, it shouldn't be of much use, right?" Qin Shiou asked suspiciously.

Frank said, "Yes, sir." If only one base station is built on the island, the radiation range extends to 20 kilometers into the ocean at most. But. If you build a communications cluster on the island, install a shipboard terminal on your ship. That radiation range can enter the ocean for 400 kilometers! ”

"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 roll it out to the civilian market? A communication distance of 400 kilometers is very tempting for home communication, right? Qin Shiou asked strangely.

Frank smiled bitterly, "That's not going to work, sir, it's useless. Our tetra needs the base station host and the base station terminal to work together, whether it is the host or the terminal, the size and weight are too large. It cannot be used on the bus. What's more, who likes to walk around with a heavy walkie-talkie? ”

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

Seeing that Qin Shiou had the intention of building a cluster base station, Frank was in high spirits, the cluster base station was not something that could be done for tens of thousands of yuan, if he could win a customer, just raising achievements would be higher 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 very uniform oval, and there is also Mount Cambar in the northeast, and the peak of the mountain is built with a base station host, so the radiation range can be more extensive. ”

"My building yì is. You can build four base stations as a cluster on the pan island, of which the Khambar base station is the first host, according to the 800M tetra. Others with 400m on it, so the island around the ocean. It's all your communications territory. ”

"If you want to build a four-online cluster, it will cost about 500,000 yuan."

Half a million. Qin Shiou thought about it and was just about to nod, Hamlet suddenly reached out and hugged his shoulder, and said with a thief's eyebrows: "Don't rush to make a decision, Qin, I said that you have no problem building a base station, can you let our townspeople follow with some light?" ”

As soon as Hamlet said this, Qin Shiou understood what this guy meant, and wanted him to open the trunking wireless channel, so that as long as they had the password, the townspeople could talk to each other for free if they bought a walkie-talkie.

More than that, with the radio, many things are simpler, such as the guide leading the climb of Mount Cambar, there is no signal in the mountain, so every time tourists enter the mountain, they must be equipped with additional manpower to prevent accidents.

With a radio that can radiate the whole island, let each tourist bring a walkie-talkie into the mountain, then there is no fear of anything, even if the tourists leave the group and get lost in the mountains, they can be found.

Qin Shiou is not a stingy person, and it is not a problem to let the townspeople follow him to get some light, but he has to ask clearly: "After forming a radio cluster, how many people can use it at most?" ”

"You're talking about how many private terminals you can connect to?" "You don't have to worry about this, TETRA uses digital time division multiple access technology, which makes the system more powerful, the communication quality is better, the security performance is better, and the frequency resources are used more efficiently......"

"Dude, don't talk clichés, okay?"

"Sorry sir, I'm used to it. Well, let me introduce that our TETRA system, Dimetra, is currently the world's most technologically advanced and productized digital trunking communication system. In terms of transmission mode, it can not only provide 'one-to-one' full-duplex cellular telephone service, but also carry out fast 'one-to-many' team scheduling communication, and can open 16 channels after building a cluster, enough for 1,600 private terminals to access. Frank introduced.

"Absolutely enough." Hamley said with a smile.

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

"Oh, don't do that, my fellow, you'll say yes, won't you? In fact, if we can enjoy your channel, it will also help the fishing grounds, if there is any problem, you shout on the public channel, then the whole town will know, and if someone is looking for you trouble, the big guy can help you as soon as possible. Hamre said.

A politician is a politician, Qin Shiou heard that it was really like this, his base station cluster is equivalent to connecting every household in the town to a network, and whoever is in trouble is a matter of one sentence.

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

"You can also help you with advice on how to win the Gatoroli Fishery on the public channel." Hamlet was afraid that Qin Shiou would not be willing, so he continued to throw out seductive topics.

However, this was trivial to Qin Shiou, he waved his hand and said, "Just leave it to me at the Gatoroli Fishery, I can handle it." ”

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

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

The hot springs have not yet been expanded, and they have a pristine smell, and after digging for a while, the hot springs continue to gush upwards with sulfur steam, and the surrounding stones are yellowish with a faint smell of sulfur.

Qin Shiou put a recliner in the water, and then lay down, well, the water is a little hot, and it is comfortable.

It is better to be happy alone than to be happy with everyone, Qin Shiou beckoned to the tiger and leopard, and the two little guys jumped to him left and right and followed him and lay on the recliner.

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

"Damn, don't!" Qin Shiou screamed! (To be continued......) R1292
