Chapter 501

After listening to Frank Kent's introduction, Qin Shiou still didn't understand the working principle of the so-called tetra, but it doesn't matter. It's like North American Slang: if you want to eat a chicken, you have to eat it. You don't have to figure out how to do it.

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

He told Frank about his goal. Frank said happily, "it's no problem. The civil private airport only needs a 100m power communication base station, which costs about 100000 yuan."

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

Hamley listened to Qin Shiou's discussion with frank, his eyes turned, his mouth stirred, showed a smile, and then said, "Qin, aren't you going to get a TETRA digital time division multiple access base station?"

"It's no use asking for it."

"No, no, man, of course it works. You see, your fishing ground is so large that when you produce fish, multiple fishing boats must work together. Are you going to use your mobile phone to communicate then? The sea signal is not good. "

After listening to Hamley, Qin Shiou thought it was reasonable.

Farewell town has its own mobile communication base station, but the power is not large. Qin Shiou's mobile phone signal is dissatisfied all year round. Once it rains and winds, 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 cluster base stations? I think if a base station is built on the island, it should be of little effect?" Qin Shiou asked suspiciously.

Frank said, "yes, sir, if only one base station is built on the island, the radiation range can extend up to 20 kilometers into the ocean. However, if you build a communication cluster on the island and install shipborne terminals on your ship, the radiation range can enter the ocean for 400 kilometers! "

"So overbearing?" Qin Shiou asked in surprise. Frank felt the distance of 400 kilometers silently and couldn't help nodding.

"If your TETRA system is so powerful, why not promote it to the civil market? A communication distance of 400 kilometers is very tempting for home communication, isn't it? " Qin Shiou asked strangely.

Frank said with a bitter smile, "that won't work, sir. It's useless. Our tetra needs to be used together with the base station host and the base station terminal. Both the host and the terminal are too large in volume and weight to be used on the vehicle. Besides, who likes to walk around with a heavy walkie talkie? "

Qin Shiou thinks so. Mobile communication costs in Canada and the United States are relatively low. Ordinary calls at night and on weekends don't even cost money.

Looking at Qin Shiou's intention to build a cluster base station, Frank is in high spirits. The cluster base station can't be done for tens of thousands of yuan. If he can win a customer, the Commission alone will be higher than his monthly salary.

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

"My suggestion is that you can build four base stations on the pan island as clusters, with kambar base station as the first host, 800m tetra and 400m for others. In this way, the oceans around the island are your communication territory."

"If you want to build a four online cluster, the price of about 500000 can be done."

Five hundred thousand, Qin Shiou thought. Just about to nod, Hamley put his hand around his shoulder and said stealthily, "don't hurry to make a decision, Qin, I said you have no problem building the foundation station. Can you let our villagers follow?"

When Hamley 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 a password, the townspeople could talk to each other free of charge by buying a walkie talkie.

More than that, with the radio, many things are simple. For example, the guide leads the team to climb kambar mountain. There is no signal in the mountain, so every time tourists enter the mountain, they have to be equipped with additional personnel to prevent accidents.

With a radio that can radiate the whole island and let each tourist bring a walkie talkie into the mountain, he will not be afraid of anything. Even if the tourists leave the team and get lost in the mountain, they can find them.

Qin Shiou is not a stingy person. It's not a matter for the villagers to follow him. However, he must first ask clearly: "how many people can use it after forming a radio cluster?"

"You mean how many private terminals can be connected?" Frank asked, "you don't have to worry about this. Tetra adopts digital time division multiple access technology, which has stronger system function, better communication quality, better security performance and more effective use of frequency resources..."

"Man, don't talk nonsense, OK?"

"I'm sorry, sir. I'm used to it. OK, let me introduce that our TETRA system dimetra is the digital trunking communication system with the most advanced technology and the highest degree of product in the world. 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. After a cluster is built, 16 channels can be opened, enough for 1600 private terminals to access. " Frank introduced.

"Absolutely enough." Hamley said with a smile.

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

"Oh, come on, my man, you'll promise, won't you? In fact, if we can enjoy your channel, it will also help the fishing ground. If there is any problem, shout on the public channel and the whole town will know. If someone asks you for trouble, big guys can help you at the first time. " Hamley said.

Politicians are politicians. Qin Shiou's base station cluster is really like this. His base station cluster is equivalent to connecting every family in the town to a network. It's a matter of one sentence if anyone is in trouble.

Thinking of this, he naturally said nothing. OK, build it. Then build a base station cluster.

"You can also give advice on how to win Jiadeli fishery on the public channel." Afraid of Qin Shiou's unwillingness, Hamley continued to throw out tempting topics.

However, this is a little fun for Qin Shiou. He waved his hand and said, "just give me Jiadeli fishing ground. I can handle it."

Qin Shiou decided to build a base station, but Frank didn't go. He called the company and directly delivered the machines to farewell island.

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

The hot spring has not been expanded, and it has a very original ecological flavor. After digging this period of time, the hot spring keeps pouring sulfur steam upward, 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 comfortable.

Dullele is not as good as zhonglele. Qin Shiou waved to the tiger and leopard. The two little guys jumped to him from left to right and lay down on the couch.

When Xiong Da saw that they were underwater, he became curious and jumped to Qin Shiou with his fat ass.

"Sleeping trough, no!" Qin Shiou screamed!
