Where the cell phone signal is coming from

You can check it.

The mobile phone signal is sent by the mobile phone signal station, and when two people are talking, the mobile phone signal is transmitted through the mobile phone signal station and then through the relay station. In order to ensure the quality of the call and prevent the number channeling, the mobile phone signal will be attached to the mobile phone signal station and the station of the mobile phone relay station**. The technology of the telecommunications company can find out the location of the caller based on these **.

One of the services in Beijing's Dynamic Zone is a "Dynamic Location" service, which uses this technology to return the current location of the mobile phone holder. Therefore, when the other party's mobile phone ** card is a mobile company's "Dynamic Zone" card, you can use this service to check the other party's current location. There is a "You are in **" in the dynamic location of the Dynamic Zone service.

However, if you don't have this service, you won't be able to look it up. Telecom companies don't have that big database to keep track of the "transmission paths" of all calls, which you can imagine with your toes, and there is no need for this, so you can only do this by preparing in advance and monitoring the process of the call. However, according to China's communications laws, you cannot casually monitor other people's phone calls, and only the public security procuratorate and the courts have this right.

So to sum up, you can see how to achieve your goals according to your situation and your needs. If you casually want to know where someone is, you're kidding

Actually, it's not that hard to look this up. But generally they don't check it, which is confidential or private customer information.

If you really need to check, you need the mobile company's special signal segment query test software. This is what they use when they test the towers, and you can't get them.

Don't think about looking it up, except for our staff.

The specific incoming mobile phone call is logged in at the base station, I am afraid that only the operator can find out, and for private needs, the operator will generally not meet your wishes. If you turn on the power frequency mode of your mobile phone, you can only find out the base station number that you are currently logged into.

The mobile phone can't find the specific location, and there is a GPS global positioning system.

You can check it, do you want to know the theory or the method of checking?

This mobile company can be queried, and I have tried this query.

Signals are received through electromagnetic bai waves.

DU1831, England Zhi

Faraday discovered the phenomenon of electromagnetic induction, and Maxwell's version further expounded the research results of Faraday et al. with the formula of number weight, and extended the theory of electromagnetic induction to space.

More than 60 years later, Hertz experimentally confirmed the existence of electromagnetic waves. The discovery of electromagnetic waves became a turning point in the transition from wired electricity to radio communication, and also became the birthpoint of the entire mobile communication.

The interface of the mobile phone is modulated into a high-frequency signal through signal processing and transmitted to the satellite, and the satellite is then transmitted to the target number, and the target mobile phone realizes signal transmission by demodulating the high-frequency signal into the corresponding interface signal and voice and other information.

Take the iPhone as an example:

In the frame of the fuselage, the signal receiver is shown below;

Mobile phone signal amplifier (professional name: repeater) consists of antenna, RF duplexer, low noise amplifier, mixer, ESC attenuator, filter, power amplifier and other components or modules composed of upstream and downstream amplification links. The basic principle of its operation is:

The forward antenna (donor antenna) is used to receive the downlink signal of the base station into the repeater, and the useful signal is amplified through the low-noise amplifier, the noise signal in the signal is suppressed, and the signal-to-noise ratio (SN) is improved. Then it is downconverted to the intermediate frequency signal, filtered by the filter, the intermediate frequency is amplified, and then the frequency is shifted to the radio frequency, and then the frequency is amplified by the power amplifier, and the backward antenna (retransmission antenna) is transmitted to the mobile station; At the same time, the backward antenna is used to receive the uplink signal of the mobile station, which is processed by the uplink amplification link along the opposite path: that is, it is transmitted to the base station through the low-noise amplifier, downconverter, filter, mid-amplifier, upconverter and power amplifier. So as to achieve two-way communication between the base station and the mobile station.

Generally in the upper left corner of the phone! Like the iphone is in the upper left corner MT is also nokia is all Thank you for adopting.

There is no mobile phone signal in the countryside, so sell a mobile phone number station.

The solution to the mobile phone without 4G signal: 1. Check whether the mobile phone has been shut down in arrears, if the mobile phone is down, the 4G function will be turned off, and only the function of receiving ** will be retained.

2. Currently in the basement, elevator or crowded places, the ability of mobile phones to receive signals in these places will be weakened, it is recommended to go to an open place with few people to check whether the signal can become a 4G signal.

3. Open Settings, find Mobile Network, and check if the 4G function is turned off.

Ways to solve the mobile phone WiFi signal disconnection: Method 1: 1. Click to enter the advanced settings in the WLAN settings, select the fixed frequency band in the WLAN frequency band option, and do not let the WLAN be automatically selected to prevent the current interruption caused by automatic switching.

Method 2: Replace the router, many old-fashioned routers do not have a stable signal, which leads to signal interruption.

Method 3: Update the system in time, the new system will fix some bugs, and it will be more stable to use.
