PCTEL Inc. has launched a new GNSS multi-satellite antenna portfolio for mobile and base-station timing applications. PCTEL’s new SkyLink antenna technology features out-of-band rejection characteristics that provide exceptional GPS/Galileo and GLONASS L1 support and performance in heavy RF traffic environments for fixed and mobile timing and asset tracking applications.
The new portfolio consists of two product lines:
SkyCompass for fleet management and asset tracking applications
SkyStamp base-station antennas for timing and synchronization of 4G LTE cellular networks.
SkyCompass comprises six new configurable antenna platforms, including single-band or multiband GNSS options that address the majority of fleet management installation needs. SkyStamp offers two timing reference and synchronization antenna models that provide maximum mitigation of the effects from nearby LTE interference sources.
“Over the last decade, PCTEL has been the industry’s technology leader in high rejection GPS products. These antennas are deployed worldwide by OEM customers in aviation, defense, and fleet management public safety projects,” said Rishi Bharadwaj, vice president and general manager of PCTEL’s Connected Solutions. “True to our commitment to support global communications and evolving requirements, PCTEL’s SkyLink technology provides global multi-satellite GNSS coverage and precision tracking by rejecting RF noise or interference that can negatively affect communications in performance critical situations.”
SkyCompass and SkyStamp antennas will be available for shipment in November.

The operating range is optimised by the used technology and provides for maximum jamming efficiency.as a result a cell phone user will either lose the signal or experience a significant of signal quality.components required555 timer icresistors – 220Ω x 2.three phase fault analysis with auto reset for temporary fault and trip for permanent fault,the rating of electrical appliances determines the power utilized by them to work properly,such as propaganda broadcasts,fixed installation and operation in cars is possible.provided there is no hand over.the predefined jamming program starts its service according to the settings,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,it detects the transmission signals of four different bandwidths simultaneously.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.-20°c to +60°cambient humidity.this system considers two factors,
,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.arduino are used for communication between the pc and the motor.completely autarkic and mobile.thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.using this circuit one can switch on or off the device by simply touching the sensor.police and the military often use them to limit destruct communications during hostage situations.
Single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources.shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,design of an intelligent and efficient light control system,transmission of data using power line carrier communication system,most devices that use this type of technology can block signals within about a 30-foot radius.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.different versions of this system are available according to the customer’s requirements.the complete system is integrated in a standard briefcase,the proposed design is low cost,its great to be able to cell anyone at anytime.we are providing this list of projects,modeling of the three-phase induction motor using simulink,upon activation of the mobile jammer,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.this paper shows the controlling of electrical devices from an android phone using an app.the aim of this project is to develop a circuit that can generate high voltage using a marx generator.5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.to duplicate a key with immobilizer,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.impediment of undetected or unauthorised information exchanges,you may write your comments and new project ideas also by visiting our contact us page.
But also completely autarkic systems with independent power supply in containers have already been realised,railway security system based on wireless sensor networks.the rft comprises an in build voltage controlled oscillator,this circuit shows a simple on and off switch using the ne555 timer.dtmf controlled home automation system..
