The invention discloses a GSM-based geological change timing, positioning and remote short message alarm system. January Radio Frequency RF and Mobile signal jammer is an illegal device in many countries. Based on the distribution feeder fault location system for wireless communication. JPA en. Theraja, B. Although we must be aware of the fact that nowadays lot of mobile phones can easily negotiate the jammer effect are available and therefore advance measures should be taken to jam such type of devices. These disadvantages will restrict the use of Radio Frequency jammer.

GSM transceiver system and presents that achieved results in comparison to the ETSI GSM specifications. Figure 1(b): Transceiver block diagram (Downlink).
The GSM-based geological change timing, positioning and remote short message alarm system of the invention is simple in structure and is convenient to install.
This device will block the transmission of Radio and GSM signals.
CONSTRUCTION OF RADIO FREQUENCY GSM SIGNAL JAMMER Project Topics
A Radio Frequency jammer is a device used to disrupt or prevent communication via a broadcasted RF signal. The frequency can then be varied using a frequency tuner mounted on the jammer:. Principles of Wireless Communications, 4th Ed. CNY en. The GSM-based geological change timing, positioning and remote short message alarm system includes a power source module, a single-chip microcomputer as well as a vibration detection module, a rainwater detection module, a temperature detection module, a battery voltage detection module, an operation indication module, a GPS receiving module and a GSM receiving and transmitting module which are respectively connected with the single-chip microcomputer, wherein the power source module comprises a solar panel, a charging module, a storage battery and a voltage stabilizing module which are connected with one another sequentially, and is used for providing storage battery voltage and a voltage stabilized power source for the single-chip microcomputer and the above modules.
Most modern GPS receiver designs are digital receivers. For this reason, a high-level block diagram of a modern generic digital GPS receiver will be used to.

Ahlin, L. This project is mainly intended to prevent the usage of mobile phones in places inside it coverage without interfering with communication channels outside it range, thus providing a cheap and reliable method for blocking mobile communication in the required restricted area only.
CNC en. From Fig. The device can possibly block these frequencies by transmitting a dirty signal like noise on the same frequency at which the GSM and radio system operates. These requirements fulfil the GSM specifications. It can be said that the resultant of the signals is zero.
