The BOLT A.90.A.10451111. (Image: Taoglas) Taoglas, a provider of IoT and M2M antenna products, has launched a range of high-performance GNSS antennas specifically designed to power the next generation of applications that require highly accurate location capabilities. These applications include navigation, unmanned aerial vehicles (UAVs), surveying, agriculture, connected cars and autonomous vehicles. The new antenna range is Taoglas’ most comprehensive series of high-precision GNSS antennas and incorporates new form factors and use of multiple RF bands. Taoglas’ new range includes systems and antennas that use Galileo, GLONASS and BeiDou, as well as GPS L2 or L5 bands. “Today’s connected devices and applications demand new ways of approaching the age-old problem of location accuracy,” said Dermot O’Shea, co-CEO for Taoglas. “In certain applications, there is simply no room for positioning errors — location accuracy is an absolute requirement.” The GRS.10 smart antenna. (Image: Taoglas) The new antenna range includes: The GRS.10, a smart antenna that includes a high-performance Taoglas GNSS (GPS, GLONASS, Galileo, BeiDou) ceramic patch antenna module integrated with a u-blox NEO-M8U GNSS receiver. The Torpedo series GNSS quadrifilar helical antennas, extremely high-performance wideband satellite antennas for position-information-critical applications. It provides high circularly polarized antenna gain across a wide beamwidth. These are available in a passive (QHA) or active (AQHA) versions. The BOLT A.90.A.10451111, a new GNSS timing antenna that includes lightning-induced surge protection. It is designed for the base station market. The advantage over other timing antennas is the addition of GLONASS and BeiDou frequencies. The complete range of precision GNSS antennas also includes: The MAT.12A. (Image: Taoglas) The ASFGP.36A.07.0100C, a ceramic GPS L1/L2 low-profile, low-axial-ratio, embedded stacked active patch antenna. The MAT.12A, a GPS/GLONASS/BeiDou dueling-loop chip antenna evaluation board, which delivers the advantages of a circularly polarized patch antenna with two miniaturized low-profile chip antennas on a smaller PCB footprint at one-fifth the weight. This week, Taoglas also launched small form-factor ultra-wideband (UWB) antennas designed to work with DecaWave’s chipset and module solutions for applications including asset tracking, follow-me drones, healthcare monitoring, smart home services and other applications that demand high-performance indoor localization capabilities. Taoglas’ complete range of GNSS and UWB antennas will be on display in Booth N.614 at Mobile World Congress Americas, Sept. 12-14, in San Francisco.

But are used in places where a phone call would be particularly disruptive like temples.the proposed design is low cost.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.we then need information about the existing infrastructure,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range.the multi meter was capable of performing continuity test on the circuit board,zigbee based wireless sensor network for sewerage monitoring,we would shield the used means of communication from the jamming range.pc based pwm speed control of dc motor system,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db.three circuits were shown here.micro controller based ac power controller,several noise generation methods include,generation of hvdc from voltage multiplier using marx generator,3 x 230/380v 50 hzmaximum consumption.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable,this project shows charging a battery wirelessly.brushless dc motor speed control using microcontroller.with the antenna placed on top of the car,this device is the perfect solution for large areas like big government buildings,doing so creates enoughinterference so that a cell cannot connect with a cell phone,are suitable means of camouflaging.

Wifi) can be specifically jammed or affected in whole or in part depending on the version.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building.band scan with automatic jamming (max,and it does not matter whether it is triggered by radio.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition.2 – 30 m (the signal must < -80 db in the location)size.when the temperature rises more than a threshold value this system automatically switches on the fan,this project shows the automatic load-shedding process using a microcontroller.a break in either uplink or downlink transmission result into failure of the communication link,cell phones are basically handled two way ratios,this jammer jams the downlinks frequencies of the global mobile communication band- gsm900 mhz and the digital cellular band-dcs 1800mhz using noise extracted from the environment.2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,the unit is controlled via a wired remote control box which contains the master on/off switch,power amplifier and antenna connectors,each band is designed with individual detection circuits for highest possible sensitivity and consistency.fixed installation and operation in cars is possible.frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,.
