An active cellular system is a type of wireless communication system that uses a network of base stations to provide coverage over a large geographic area.
It is called “active” because the base stations are connected to a central network and actively transmit and receive signals to and from mobile devices.
Active cellular systems are widely used in mobile communications, such as cellular phones, wireless internet, and other wireless applications.
They are also used in public safety systems, such as emergency responders and first responders, to provide reliable communication in remote or hard-to-reach areas.
Cellular networks GSM/UMTS/LTE is the most common standard for mobile communication in today’s modern life.
It is used all over the world, network’s signal is available almost everywhere. People are carrying their mobile phones anywhere at all times.
Mobile phones or user equipment are more than just a phone, they are used for constant and continuous communication, personal data is saved on it, contacts list, social networks connections, online payment, and more. The mobile cellular phone has become as personal as an ID card.
collecting IMSI numbers and assigning them to the phone’s owner, is essential for Law Enforcement investigation, not only to combat criminal activities but also for other tasks like searching for missing persons, etc.
In addition, once the target is identified, his voice and text communication can be monitored, and call and SMS recorded and reproduced upon request.
One of the key benefits of active cellular systems is their ability to provide coverage over a wide area.
This is achieved by dividing the coverage area into smaller cells, each of which is served by a base station.
The base stations are connected to a central network, which allows them to communicate with each other and route calls and data to the appropriate destination.
Another important feature of active cellular systems is their ability to provide reliable communication in a variety of environments.
This is achieved by using advanced modulation techniques, such as CDMA, which can provide reliable communication even in the presence of interference or fading.
Additionally, active cellular systems use advanced error-correction techniques to ensure that data is transmitted accurately and without errors.
In conclusion, active cellular systems are a key technology in today’s wireless communication landscape.
They provide coverage over a wide area, support a large number of simultaneous users, and provide reliable communication in a variety of environments.
They are widely used in mobile communications, M2M communications, vehicular communications, and public safety systems.
