Chapter 365: Drinking Cold Water Also Gets Stuck in Teeth (2)
Sun Liang discovered that during this period, Qiao Keli's calls mainly came from three sources:
One was Qiao Keli's wife and her lawyer, and their conversation with Qiao Keli was mainly about discussing the specific details of property division.
When wealthy people divorce, the most important issue is the division of property. Because there's so much wealth, dividing it up can be a bit tedious. For example, a property appraisal must be conducted on all assets held by both spouses, such as houses, to determine their value... The same applies to cars and yachts. Also, all valuables and securities...
They often started arguing on the phone while talking, and both sides' words were very unpleasant, sometimes even unbearable to hear.
The second most frequent calls were with lawyers and police in Guangdong. The lawyers were seeking to prosecute the general manager, who had fled abroad, while the police were using every available means to track down the general manager and his relatives who had absconded with the funds. On two occasions, Sun Liang even detected Qiao Keli's phone signal at a five-star hotel in Shenzhen.
The third was to call Yong Wu to discuss a meeting to discuss the three people's arrest...
Tracking Qiao Keli's cell phone signal and monitoring his calls was not difficult for the police. This was because when the police were investigating a case, the telecommunications departments such as China Mobile, China Unicom, and China Telecom had to cooperate with the investigation.
There are currently three ways to track a cell phone:
One method is base station positioning, or SIM card signal positioning. Mobile phones can make calls across the country because mobile companies have built cell phone signal towers in every region, often referred to as signal towers. When a phone passes by a tower, that tower records the corresponding signal. Based on this, as long as the suspect's phone is on, the police can roughly determine the suspect's location. However, if the suspect turns off the phone or removes the SIM card, the location becomes impossible. However, if the phone is previously linked to a SIM card, it will search for a base station when it is turned on. The base station will record which numbers the phone has been linked to, allowing the suspect's phone to be tracked.
The second type of positioning is GPS. Modern smartphones all have built-in GPS systems. If a phone's GPS is enabled, it can track the current location of the person holding the phone. Even if the phone is turned off, as long as the battery is still connected to the phone, GPS can still be connected.
The third method is location tracking using IFI connection points. Mobile phone communications transmit signals through base stations spaced a certain distance apart. Within the telecommunications company, each base station's location and internal number are fixed. Each base station's coverage area is a circle centered on the base station. Multiple base stations can simultaneously transmit and receive radio signals, so accurate positioning can be achieved using at least three base stations.
As for fixed-line phone positioning, it is even simpler. Because when installing a fixed-line phone, you must register your real name with the telecommunications department. The telecommunications department will collect all this information.
"What's wrong with you? You hired an unreliable lawyer who can't even do the math." Qiao Keli's anger towards his wife could be heard over the phone.
"The lawyer I hired is the best lawyer in Huacheng. I didn't make any mistakes in the calculation, it was you who made the mistake! Don't slander me..." Qiao Keli's wife.
"If you continue to be unreasonable, I will sue you in court!" Qiao Keli's wife refused to give in and maintained a firm attitude.
Both of them were very angry, and they started arguing again...
When a couple who married voluntarily reach the point of divorce, their attitudes become like those of enemies—no longer tolerant, no longer friendly, and even intolerant...
Sun Liang pondered.
