Seeing that this phone can actually make calls to the Soviet Union is not as simple as it is convenient. It is simply an artifact, which can greatly improve the frequency and efficiency of people's contact. As Bao Zixuan said, you can be found anywhere in the world.

Bao Zixuan said: "It seems that Brahova lives in a happy family, her father is a mechanical management engineer, her mother is a teacher, and her younger brother has been admitted to the best university in the Soviet Union. She is also very good, so Family is very beautiful to me."

Branova: "Thank you Mr. Bao for giving me this opportunity. If I was really reluctant to talk to my father on the phone for so long. The cost of calling from the US to the Soviet Union is too high."

Bao Zixuan: "This is a small matter, I would also like to thank you for giving us a chance to test the performance of the mobile phone. Who else wants to call home and friends, we are choosing the last one. As for the future, you can only Wait until the phone hits the market to experience its capabilities.

A middle-aged man stepped onto the stage and said to Bao Zixuan, "I'm David Owen, a teacher at Oxford University, UK. Can I make a phone call to Oxford University?"

Bao Zixuan: "Of course, I graduated from Oxford, but I didn't see you when I was studying, so I don't know you. I hope you don't take offense."

David Owen: "I'm a teacher of electronics and you're a student of aerodynamics. But I'm proud that Oxford has produced students like you."

After calling the Oxford University Electronics Laboratory, a female voice came from the opposite side and said, "Hello! This is David Owen's laboratory! How can I help you!"

David Owen: "Is that Shirley? I'm Professor David Owen. I'm calling you on my phone now, mainly to test his performance. Is the call clear to you?"

Shirley: "The call is very clear, I can hear every word you say!"

David Owen: "That's good, I'll hang up."

Bao Zixuan said to Professor David Owen, "Professor Owen, how is the performance of our product!"

David Owen: "Awesome! I can't believe there is such a convenient product in the world."

With the approval of David Owen, an expert in electronics, the authority of Black Cloud Mobile has been confirmed. Bao Zixuan said: "The mobile phone demonstration has been completed, and the next step is the reporter's question-and-answer session. You can ask questions at will."

A young male reporter asked: "Hello, Mr. Bao! I would like to ask you what the price of this phone is!"

Bao Zixuan: "The Black Cloud phone is divided into two versions. The uniform black version for men is priced at $2,388 each. The color version for women requires special customization, so each unit is priced at $2,588."

Hearing that the women's version is more expensive than the men's version makes many men worry about their wallets. After all, if you don't use it yourself and buy one for your wife, it's definitely not easy at home.

Another middle-aged reporter asked: "Hello Baosheng! Where can I use this phone now."

Bao Zixuan: "We only opened seven cities in the first batch, including six cities in the United States, Los Angeles, New York, Boston, Chicago, Atlanta and Detroit; only one city in Asia was opened, and that was Hong Kong."

"These 7 cities can be used by everyone now. As for other needs, we will continue to open up. The initial infrastructure investment is very huge, and we need to build signal towers in each city. We will also seek cooperation with local telephone companies. In order to achieve full coverage of the network , let more people use Heiyun mobile phones."

Then a beautiful reporter asked: "Mr. Bao, hello! I would like to ask how much is the construction price of a cell phone tower; what is the coverage area?"

Bao Zixuan: "There are two types of signal towers, one is the outdoor type. Its price is 2 million US dollars and can cover a radius of 20 kilometers. The disadvantage is that the ability to penetrate walls is weak. One is the urban use type, the price is It costs $300,000 per unit. It can cover a 5-kilometer radius and has a strong ability to penetrate walls, but the signal transmission distance is short.

At this time, beauties always have some privileges, and the beauty reporter then asked: "What should we do if we want to contact this mobile phone."

Bao Zixuan: "Our Heiyun mobile phone has two number segment modes. One can be installed by the telephone company with a fixed number, similar to a car phone. The other is a phone card developed by Heiyun, as long as the number is distinguished. To form another kind of number segment system independently, which requires the telephone company to choose by itself, and can also decide according to customer needs.

At this time, a Xiangjiang reporter asked: "Hello, Baosheng! I would like to ask what number tier is being used in Heiyun, Xiangjiang, and when will we be able to buy it."

Bao Zixuan: "In Xiangjiang, we have used a set of independent number segments in Heiyun. There is a device at the terminal that can copy the number to the phone card through the computer, then this number is yours."

"Heiyun uses an 11-digit phone number to distinguish the existing fixed number system. Currently, Heiyun stores in Xiangjiang already have mobile phones for sale."

"At the same time, the first batch of mobile phones has been distributed to the management of Heiyun. The first is for testing, and the second is to popularize mobile phone usage. It will make our work more efficient."

Then another female reporter asked: "Hello, Mr. Bao! How can the signal tower form a network? If I use a Hong Kong phone number, can it be used in the United States!"

Bao Zixuan: "The signal tower can cover every corner of the city where it is located, and the telephone company can be connected to the landline system when operating, so that a larger network can be formed."

"Xiangjiang's phone number can of course be used in the United States, but the price is much higher. Because you have to pay roaming charges to the U.S. operator. After all, this place uses a remote signal connection, and to put it bluntly, you have to pay double the fee."

"For example, the price of a phone number in Xiangjiang is US$0.1/minute when used in Xiangjiang, and it may cost US$0.2/minute when used in the United States. So I don't recommend applying for a number in another place~www.mtlnovel.com~ This will increase the usage fee. "

Everyone was scrambling to ask Bao Zixuan all kinds of questions. A reporter asked, "Hello, Mr. Bao! How can I prevent the thief from using the phone if it is lost?"

Bao Zixuan: "You can contact the operator at this time, and they will cancel your number. This way, once the phone sends out a signal, it will be locked and cannot be used in the future. But you want me to help you find it. technology can't do it.

The reporter next to him asked: "Hello, Mr. Bao! I would like to ask if this phone can be used by linking satellites in places where there is no signal!"

Bao Zixuan: "It is absolutely possible, provided that the satellite company agrees with you to access the signal. However, such a fee is not affordable for ordinary people. After all, the basic cost of satellite communication is very high."

"Heiyun mobile phone supports multiple communication modes, and we have put a lot of effort into this aspect. It is to make customers feel at ease when using it, so that they can easily and quickly contact the people you want to contact."

"There is one last question, leave it to a beauty!" Seeing Bao Zixuan looking at him, the beauty reporter asked happily, "Can this phone be used for military purposes."

Bao Zixuan: "Theoretically, yes, as long as there are signal towers in the area where the two warring parties are located. And the signal towers can still work normally, but I personally recommend not to use them in the military. Military equipment has strong anti-jamming capabilities, and Heiyun mobile phones can reach Less than requirements. All the chips and components we use are civilian products, and the strength is not up to military requirements.

Hearing that it cannot be used in the military is very reassuring to the US intelligence agencies. After all, if this thing is used in the military, it is really difficult to control, and now these concerns have been eliminated, but further investigation is needed.
