Usually this question needs to be judged according to the scene. There are many objective factors here. For example: connectivity technology, landscape features, power of transmitters in towers, cell size of cell phone networks and the designed capacity of the network all play a role. Sometimes base station transmitters are deliberately set to low power [...]
A mobile phone signal is the signal strength received by a mobile phone from a cellular network. Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength will vary. How does a cell phone signal work? Whenever a cell phone is used, it emits [...]
5G signals usually use some of the frequency bands of 4G signals. Of course, 5G also has millimeter wave base station equipment, but most countries do not use millimeter wave equipment. Because of the short distance of millimeter waves, the construction of base stations is difficult, the cost is high, and the economy is [...]
What is mobile phone jammer? A mobile phone signal jammer is a device that blocks reception between cell towers and mobile phones. A mobile phone jammer transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. It’s a called a denial-of-service [...]
