The mobile phone short message advertisement has a radiation range of 5 kilometers, which saves you the trouble of printing and distributing paper advertisements. The delivery speed is 50,000 pieces per hour. This short message was sent through a pseudo base station.

A pseudo base station is a pseudo base station that forcibly sends short messages such as fraud and advertisements to users' mobile phones by using other people's mobile phone numbers at will and pretends to be an operator.

It is a high-tech instrument assembled and produced by lawless elements privately, which is mainly composed of host computer, notebook computer, short message transmitter, radio frequency unit and so on. Criminals usually put the pseudo base station equipment in the car, drive slowly or park the car in a specific area, search for the user's mobile phone signal within a certain radius around it, and send fraudulent short messages and advertising information.

Sending spam through pseudo base stations seriously endangers national communication security and social public order, which is an illegal and criminal act.
