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.
