Millions of people use mobile phones in the United States and around the world. These gadgets are great - you can chat with people anywhere!
But have you ever thought about how to use your cell phone? What makes it different from ordinary phones? PCS, GSM, CDMA and TDMA what do these terms mean? In this article, we'll talk about the technology behind the phone so you can see how great they really are.
Portable cell phone jammer.For starters, one of the most interesting things about mobile phones is that it's actually a radio - a very complicated radio, but still a radio. Telephone was invented by Alexander Graham Bell in 1876, the wireless communication can trace its roots in the 1880 s of radio invented by nikola tesla (by a young Italian named Marconi in 1894 formally proposed). It is therefore natural that these two great technologies will eventually be merged.
The genius of the mobile phone system is to divide a city into smaller systems. This can be widely used throughout the city, so that millions of people can use mobile phones at the same time.
A good way to understand the subtlety of a cell phone is to compare it to a CB radio or walkie-talkie.
In a full-duplex radio, two transmitters use different frequencies so that the speaker can talk simultaneously. The phone is full duplex.
Full duplex and half duplex - two intercom and CB radio are half duplex equipment. That is, two people on a CB radio use the same frequency, so only one person can speak at a time. The cell phone is a full-duplex device. That means you use one frequency to speak, another frequency to listen. The caller can speak at once.
Channel - a walkie-talkie usually has a channel, and a CB radio has 40 channels. A typical mobile phone can be on 1664 channels or more communication!
Range - the interphone can transmit about a mile (1.6 kilometers) using a 0.25 watt transmitter. CB radio is capable of transmitting about 5 miles (8 km) using a 5 watt transmitter because of its higher power. Cell phones work inside cells, they can change the cell movement. These cells provide incredible phones. People can travel hundreds of miles with their mobile phones and keep talking because of the cellular approach.
Because cell phones signal jammer and base stations use low-power transmitters, the same frequency can be repeated in non-adjacent communities. Purple cells can use the same frequency again and again.
In a typical American analog phone system, mobile phone operators receive about 800 frequencies for use throughout the city. The carrier cuts off the city in the cell. Each neighborhood is usually about 10 square miles (26 square kilometers).
Each community has a base station consisting of a tower and a small building containing radio equipment. We'll get to the base station later. First, let's look at the cell phone that makes up the cellular system.
When you start a legitimate phone scrambler, you can block any movement signal within a given range. In the case of a GSM network, the technology is the same as the technology used to destroy radio waves. We all know that our phones use antennas on specific networks to build signals. What a wave interference is simply sending the same radio frequency as a mobile signal, and in this way, it breaks the connection between the phone and the nearest antenna. So the United States has a legal portable jammer!
Public order, national defense and national security, or just public services. The dual utility of this device: buy a wifi jammer.
With him, you can't find your GPS technology. In fact, it can prevent your location by picking up your location or providing a GPS signal scrambling system that provides geolocation services.
In addition, the GSM jammer feature lets you protect a specific environment from using the GPS jammer operator's launcher or retransmitter.
This deceiver is very effective, it will go beyond the satellite launch signal, far away, and give the whole place false information.
The bluetooth jammer has been used by truck drivers who want to escape the company's supervision. In many countries, it is forbidden to use them, but it is easy to get them for $50 to buy a jamming pocket. They can access it freely through the Internet.
In the dark ages before mobile phones, people really need to install cellular radio communication on their phones. In the wireless telephone system, each city has a central antenna hanger, which may have 25 channels on the tower. The central antenna means that the phone in your car needs a powerful transmitter - enough to transmit 40 or 50 miles. It also means that few people can use a wireless phone - he just doesn't have enough channels.
While practical and useful, mobile phones are not without drawbacks, especially in quiet places where devices or their users are noisy. Some manufacturers have had to deal with the idea that GSM interference assets should send a strong signal that a high-power jammer relay will cut off receipts to prevent the use of mobile phones.
Unmanned aerial vehicle (uav) is of the very popular equipment, its function and role to a certain extent, replaces the function of the people, but also can have flying and candid privacy to track multiple threats our behavior, using drone jammer is the best protection method.

To demonstrate the effectiveness of GPS jammers, jean-francois has arranged an appointment on a Paris metro platform. He walked up and down, put his hand in his coat pocket, ready to start the mechanism, if anyone came out on the phone. But on this platform, there are fewer unrepentant talkers than he imagines. Some people are only cautious when they hang up quickly. In the labyrinth of the station, montparnasse made a new attempt. A young woman seemed to tell her interlocutor part of her whole life. The case is operational, but it does not disturb the unknown. "We have to wait for the wave to reach the target," asked francois to try to catch up with the girl.
