Chapter 247 (2/2)
Then a beautiful reporter asked, ”Hello, Mr. Bao! I would like to ask how much the construction price of mobile phone signal tower is; What is the coverage? ”
Bao Zixuan: ”there are two types of signal towers. One is outdoor. His price is $2 million, which can cover a radius of 20 kilometers. The disadvantage is that his ability to penetrate the wall is weak. One is for urban use, with a price of 300000 US dollars. It can cover a radius of 5 kilometers, has strong wall penetration ability, but the signal transmission distance is short. ”
At this time, beauty always has some privileges. The beauty reporter then asked, ”what should we do if we want to contact this mobile phone?”
Bao Zixuan: ”our black cloud mobile phone has two number segment modes. One is that the phone company can install a fixed number for this mobile phone, which is similar to a car phone. The other is the telephone card developed by heiyun itself. As long as the numbers are distinguished, another number segment system can be formed independently, which requires the telephone company to choose by itself and can also be determined according to the needs of customers. ”
At this time, a Xiangjiang reporter asked, ”Hello, Bao Sheng! I would like to ask what number segment is currently used in Xiangjiang black cloud, and when can we buy it? ”
Bao Zixuan: ”in Xiangjiang, heiyun uses a set of independent number segments. There is a device in the terminal that can copy the number to the phone card through the computer, so this number is yours.”
”Black cloud uses an 11 digit phone number to distinguish the existing fixed number system. At present, there are mobile phones in the black cloud store in Xiangjiang. ”
”At the same time, the first batch of mobile phones have been distributed to the black cloud management. The first is to test and the second is to popularize mobile phone usage. Make our work more efficient. ”
Then another female reporter asked, ”Hello, Mr. Bao! How can the signal tower form a network? If I use Xiangjiang telephone number, can I use it in the United States? ”
Bao Zixuan: ”the signal tower can cover every corner of the city, and the telephone company can be connected with the fixed telephone system when operating, so as to form a larger network.”
”Of course, Xiangjiang's phone number can be used in the United States, but the price is much higher. Because you have to pay roaming fees to American operators. After all, we use remote signal connection here. To put it bluntly, we have to pay double fees. ”
”For example, the price of Xiangjiang's telephone number when used in Xiangjiang is US $0.1/min, and it may reach US $0.2/min when used in the United States. Therefore, I don't recommend handling numbers in different places, which will increase the use cost. ”
Everyone was scrambling to ask all kinds of questions about baozixuan. A reporter asked, ”Hello, Mr. Bao! I would like to ask how to prevent thieves from using their mobile phones after they are lost. ”
Bao Zixuan: ”at this time, you can contact the operator and they will cancel your number. In this way, once the mobile phone sends a signal, it will be locked and can not be used in the future. But you want me to help you find it. The current technology can't do it. ”
The reporter nearby asked, ”Hello, Mr. Bao! I would like to ask if this mobile phone can be used by linking satellites where there is no signal! ”
Bao Zixuan: ”absolutely, if the satellite company agrees you to access the signal. However, such costs are not affordable for ordinary people. After all, the basic cost of satellite communication is very high. ”
”Black cloud mobile phones support multiple communication modes, and we have made a lot of efforts in this regard. It is to let customers feel at ease when using it, and you can easily and quickly contact the person you want to contact. ”
”There's one last question, just give it to a beautiful woman!” Seeing baozixuan looking at himself, the beautiful reporter asked happily, ”can this mobile phone be used for military purposes?”
Bao Zixuan: ”theoretically, it is possible, provided that there are signal towers in the area where the belligerents are located. In addition, the signal tower can work normally, but I personally suggest not to use it in the military. The anti-interference ability of military equipment is very strong, and the black cloud mobile phone can not meet the requirements. All the chips and parts we use are civilian products, and the strength can not meet the military needs. ”
Hearing that it can not be used in military affairs reassures us intelligence agencies. After all, if this thing is really hard to control after military, these concerns have been eliminated, but further investigation is needed.
