What are the effects of communication base stations on the social economy?

Why build a communication base station?

Regardless of the mobile communication system, the calling and called users do not directly transmit information. The calling user transmits the demand signal and transmits it to the central computer room through the base station. The central computer room analyzes this information, determines the location of the called user, GSM jammer and transmits relevant information to the base station near the location of the called user, and the base station transmits to the called user. Since each base station has coverage distance and access capacity limitations, it is necessary to build multiple base stations to form a communication network to achieve seamless coverage of the entire area.

What is the effect of mobile communication on the social economy?

The development of mobile communications has had a profound impact on the reform of the telecommunications industry, economic growth, independent innovation and social life.

First, it has promoted the change of Chinese people’s concepts and led to the rise of communication culture. Over the past 20 years, my country’s mobile communication network has continuously expanded its coverage and enriched business content, expanding the breadth of people’s communication, deepening the depth of people’s communication, expanding the time and space of communication with each other, and accelerating people’s ways of thinking, working, and Changes in lifestyle. The reduction of information exchange cost brought about by convenient mobile communication has expanded people’s information sources and effectively promoted the improvement of national quality.

The second is to promote the improvement of social and economic operation efficiency and economic development. Through continuous innovation in business services, my country’s mobile communications industry has effectively helped related industries to reduce operating costs, avoid operating risks, improve management efficiency, promote the improvement of social and economic operation efficiency, and bring double value that is difficult to measure with money.

The rapid development of my country’s mobile communications has played a positive and direct role in attracting foreign investment, becoming a global electronic communications manufacturing base and important research and development center, and has promoted my country’s mobile communications manufacturing enterprises to enter international competition, thereby changing mobile communications systems and mobile phones. The global layout of the manufacturing industry has greatly stimulated the development of the domestic communications manufacturing industry and even the global communications manufacturing industry.

The third is to promote environmental protection. In 2009, the “thumb economy” represented by mobile phone text messages for New Year greetings reappeared. According to estimates, the number of mobile phone text messages sent nationwide during the Spring Festival holiday exceeded 18 billion. Compared with the previous paper greeting cards, 4,000 paper greeting cards are about one tree. Calculated, it is equivalent to cutting down 450,000 trees. In today’s era when paperless office is promoted, mobile communication platforms extend this concept to the extreme.

Amazon: We’re fixing a bug that leaves the Key Security Camera open to Wi-Fi interference

A malicious courier could easily freeze the key’s cloud camera and roam a customer’s home unattended.

Amazon is fixing a solution to a bug in the surveillance camera that is used to monitor couriers delivering packages to key customers’ homes.

Amazon Key is the recently launched service that allows Amazon couriers to place goods in the homes of Prime customers. The service works in tandem with Amazon’s new Cloud Cam security camera, a smart door lock, and the key app that remotely unlocks the door and displays a live video feed.

However, as Wired reports, Seattle-based security company Rhino Security Labs has discovered a bug in the process that would allow a devious courier to freeze the camera. This ability undermines the key component that gives customers security when they let a stranger into an unattended home.

The attack can be launched within Wi-Fi range, exactly where a hacker courier would be positioned. Using a computer, the attacker sends a volley of “deauthorization” packets to the target cloud camera, preventing them from using an access point when trying to authenticate again. It is a well known technique for wifi signal jammer and not specific to Cloud Cam.

Even though the Amazon camera is offline, it will still display the last image the camera took when it was connected, so the homeowner will not know that the view on their app is not live.

Rhino’s demo video shows a delivery man delivering a package as expected, but after freezing the camera on a picture with the door closed, he re-enters the house. The camera does not record the second entry and the Key app does not log the second entry.

An Amazon spokeswoman told the ZDNet sister site CNET that they are currently notifying customers when Cloud Cam is offline for a “longer period”.

An update released later this week will inform users when the camera goes offline during a delivery. The service will also not unlock the door if Wi-Fi is disabled and the camera is offline.

All major couriers undergo a comprehensive background check that Amazon checks before they can deliver at home, the spokeswoman said. In addition, Amazon links each delivery to a specific driver and verifies that it is the right driver at the right address.

The manufacturer’s opinion about the installation plan of the cell phone signal jammer in the factory

With the increasing popularity of mobile phones, the number of mobile users in China has exceeded 900 million a few years ago. The current mobile phone automation functions continue to expand. In addition to basic voice calls and short message functions, they also enjoy digital cameras and surveillance. More application functions such as camera, voice recorder, and Internet. The application of these smart phones greatly facilitates the communication and communication between people, facilitates the carrier of information, and enriches people’s lives. However, while mobile phones are actively promoting social development, there are many problems caused by the proliferation of mobile phones. The disadvantages brought about, for example, in the production workshops or assembly lines of some large factory enterprises:

16 Antennas Signal Jammer

Cell phone signal jammer manufacturers analyze why they should install signal jammers in the factory:

1. During production, workers often stop their work to answer mobile phones or reply to text messages due to a sudden call or text message.

2. Although some factories or enterprises require workers not to use mobile phones when working, there are always unconscious people who use mobile phones secretly.

3. Some workshops require a quiet operating environment, and the work environment is disturbed by someone’s sudden ringtone, and the normal work of others is affected.

4. In some assembly lines, if an employee makes a call or flips through a mobile phone, it will cause the continuity of the entire assembly line and affect production efficiency.

5. The production and processing process, processing technology, and product information of some companies belong to the company’s commercial secrets, but at any time they may be used by individual employees with ulterior motives to take photos and video recordings of smartphones. It is easy to keep confidential information outside. vent.

6. Some chemical companies that are explosion-proof and flame-proof products must strictly restrict and prevent the use of mobile phones in the factory.

To sum up, the widespread use of mobile phones is a double-edged sword. The benefits of mobile phones need not be expressed too much, but for some special places, the use of mobile phones should be restricted or even prohibited. In some special places, such as workshops, the use of mobile phones is restricted. Traditionally, relying on enumerating rules and regulations, personnel supervision, and punishment systems cannot completely eliminate and eliminate the proliferation of mobile phones. At present, it is more feasible from the perspective of technical products. The solution is to install mobile phone signal jammers or mobile phone signal shielding systems in appropriate locations in the factory area. Each mobile phone signal jammer can cover a certain area, and these coverage areas can be formed into area coverage in the form of cellular networking. Complete signal shielding to reach large areas.

The current mobile phone signal shielding projects have been able to do, for all types of mobile phone signals on the market: GSM (Mobile, Unicom), CDMA, DCS (1800MHz), PSH (PHS), 3G (including TD, WCDMA, CDMA200) , 4G, etc. are all effectively shielded. If the customer needs to add WIFI and Bluetooth shielding, it can also be added.

The current mainstream hand signal jammer manufacturers usually work in two ways:

1. Simply install a mobile phone signal jammer to achieve the most basic mobile phone signal shielding function.

2. The mobile phone signal jammer + intelligent control system is an intelligent mobile phone shielding solution in the same industry in China. It can realize the remote centralized control of any one or a group of mobile phone signal jammers, It can perform fault self-checking, alarm, automatic timing control, unattended operation and other humanized management functions for mobile phone signal jammers.
