Reflecting on the past, the time before smartphones was marked by personal interactions. We engaged in face-to-face discussions or corresponded through letters. Today, however, our attention is often directed towards our mobile screens, where various social media applications have integrated into our daily routines. We routinely take photographs, post them on Facebook, and observe the lives of others. Furthermore, the presence of mobile phones in classrooms and the ringing of notifications in restaurants, theaters, and churches have become a regular occurrence.
Mobile phone usage in professional settings often results in distractions. This phenomenon is illustrated by manufacturers that enforce a ban on mobile phones, which tend to achieve unusually high productivity rates. Consequently, it may be prudent to consider the deployment of a signal jammers to inhibit mobile signals, thus fostering improved productivity among employees. It is imperative to implement targeted measures to ensure that mobile phone usage is both healthier and more regulated.
The advent of mobile phones has significantly improved the convenience of daily activities, yet it has also fostered a greater reliance on these devices. This reliance can lead to negative behaviors, such as focusing solely on mobile phones before engaging in physical activities or during family gatherings. Such habits are detrimental. Therefore, it is essential to restrict mobile phone usage to promote a healthier lifestyle for both individuals and organizations.
Why can you still receive full signal when the signal jammer is working?
A complete signal blockage by the phone jammer takes around 30 seconds. Once this duration has elapsed, your phone will no longer be capable of making or receiving calls. This is a prevalent question among our customers, who often discover that their mobile devices are indicating a false signal.
The structure of a mobile phone base station includes a mobile switching center (MSC) and multiple base stations (BS) that fall under its control. Each base station is fitted with a receiver and a transmitter. Although the radio signal from the base station appears to cover a circular area, the true operational range of each base station is defined as a regular hexagon centered on the base station itself. Therefore, the total coverage area of all base stations can be visualized as a series of interconnected regular hexagons.
As a result, mobile communication is commonly known as cellular communication. Regarding the mobile phone located in each cell, it interacts with the base station through the channel's uplink frequency, which then transmits the signal to the Mobile Switching Center (MSC) for communication with additional mobile phones.
Frequency bands are partitioned into numerous channels, each characterized by specific bandwidths. Within a cell, several channels are employed, including the broadcast control channel (BCH) and the traffic channel (TC). In standby mode, a mobile phone intermittently activates its receiving circuit to detect the BCH of the surrounding cell. The signal strength of the BCH is represented by a signal bar, which indicates the field strength. When a user initiates an outgoing call, the mobile phone first communicates with the mobile switching center (MSC) through the BCH to obtain instructions, with the MSC managing the connection for the caller or the recipient. Based on the channel conditions in the cell, the MSC assigns a service channel to the mobile phone, enabling it to transition from the BCH to the service channel and establish a call between the two parties.
