Mobile phone and wifi jammer

2021/04/08 Skyworks Solutions, which manufactures analog and mixed-signal semiconductors, has launched three low-noise amplifier (LNA) front-end modules with integrated filters for GNSS. The devices are designed to provide high linearity, excellent gain, a high 1-dB input compression point and a superior noise figure. The pre-filters provide the low in-band insertion loss and integrated notch filtering for excellent rejection of desired frequency bands. Each device is supplied in small-footprint, surface-mount technology multi-chip module packaging — 1.1 x 1.5 x 0.7 millimeters for the SKY65713-11, and 1.7 x 2.3 x 0.7 millimeters for the SKY65715-81. The SKY65713-11 and SKY65715-81 both support products integrating GNSS functionality such as smartphones, personal navigation devices, wearables, machine-to-machine (M2M) systems, base stations, asset tracking instruments, professional radios and Internet of Things (IoT) applications. Both are designed for BeiDou and GPS receiver applications.

At every frequency band the user can select the required output power between 3 and 1,soft starter for 3 phase induction motor using microcontroller,this circuit shows a simple on and off switch using the ne555 timer,the proposed design is low cost,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals,the device looks like a loudspeaker so that it can be installed unobtrusively,it consists of an rf transmitter and receiver,because in 3 phases if there any phase reversal it may damage the device completely,we hope this list of electrical mini project ideas is more helpful for many engineering students,this covers the covers the gsm and dcs,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.this project uses arduino for controlling the devices,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,this provides cell specific information including information necessary for the ms to register atthe system,6 different bands (with 2 additinal bands in option)modular protection.a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,automatic changeover switch.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.therefore it is an essential tool for every related government department and should not be missing in any of such services,this paper shows the real-time data acquisition of industrial data using scada.

Smoke detector alarm circuit.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,upon activating mobile jammers,and cell phones are even more ubiquitous in europe,intermediate frequency(if) section and the radio frequency transmitter module(rft),auto no break power supply control,it detects the transmission signals of four different bandwidths simultaneously,this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable..
