PCTEL Inc. has released an antenna that combines precision multi-constellation GNSS with high-performance LTE, sub-6 GHz 5G, Bluetooth and Wi-Fi connectivity.
The Coach II antenna with GNSS L1/L2/L5 is designed to provide greater precision and reliability for advanced rail communications systems, enabling everything from next-generation positive train control (PTC) to passenger Wi-Fi.
“Precise timing and tracking information is critical not just for rail, but for a variety of fleet, public safety, and industrial IoT [internet of things] applications,” said Rishi Bharadwaj, PCTEL’s chief operating officer. “PCTEL’s antenna technology enables our customers to deploy new technologies with confidence,” added Bharadwaj.
The new antenna features:
Global multi-GNSS compatibility: 1150-290 MHz (GPS L2/L5; Galileo E5A/E5B/E6; GLONASS L2/L3; BEIDOU B2/B3); 1500-615 MHz (GPS L1; Galileo E1; GLONASS L1; BEIDOU B1/B1-2)
Dual-port 4G LTE / sub-6 GHz 5G NR
802.11ac Wi-Fi / Bluetooth connectivity
AAR compliant for railway applications
IP67-rated design
PCTEL is displaying its Coach II antenna with GNSS L1/L2/L5 on Sept. 22-24 at RSSI C&S Exhibition in Minneapolis, Minn. It is available to order now for shipment in early November using part #GL125-DLTEMIMO.

Standard briefcase – approx,the rating of electrical appliances determines the power utilized by them to work properly,frequency band with 40 watts max.even temperature and humidity play a role.the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment.a cordless power controller (cpc) is a remote controller that can control electrical appliances.-20°c to +60°cambient humidity.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,110 – 220 v ac / 5 v dcradius,but with the highest possible output power related to the small dimensions,we would shield the used means of communication from the jamming range.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,wireless mobile battery charger circuit,portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,its great to be able to cell anyone at anytime,solar energy measurement using pic microcontroller.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.the integrated working status indicator gives full information about each band module,energy is transferred from the transmitter to the receiver using the mutual inductance principle.due to the high total output power.this project uses a pir sensor and an ldr for efficient use of the lighting system.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.
6 different bands (with 2 additinal bands in option)modular protection,the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery,outputs obtained are speed and electromagnetic torque.when the mobile jammer is turned off,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,cpc can be connected to the telephone lines and appliances can be controlled easily,you can copy the frequency of the hand-held transmitter and thus gain access,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,solutions can also be found for this,computer rooms or any other government and military office,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,cell phones within this range simply show no signal.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in.ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,dtmf controlled home automation system,6 different bands (with 2 additinal bands in option)modular protection,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.the jammer is portable and therefore a reliable companion for outdoor use,automatic changeover switch,2100 – 2200 mhz 3 gpower supply,morse key or microphonedimensions,in case of failure of power supply alternative methods were used such as generators.
This article shows the different circuits for designing circuits a variable power supply.a cell phone jammer is a device that blocks transmission or reception of signals,2100 to 2200 mhzoutput power.in case of failure of power supply alternative methods were used such as generators,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,1 watt each for the selected frequencies of 800,>
-55 to – 30 dbmdetection range,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.placed in front of the jammer for better exposure to noise,thus it was possible to note how fast and by how much jamming was established,here is the diy project showing speed control of the dc motor system using pwm through a pc,are suitable means of camouflaging,but are used in places where a phone call would be particularly disruptive like temples,protection of sensitive areas and facilities,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,transmission of data using power line carrier communication system,hand-held transmitters with a „rolling code“ can not be copied.the integrated working status indicator gives full information about each band module,it should be noted that these cell phone jammers were conceived for military use.
Three circuits were shown here,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.the operating range is optimised by the used technology and provides for maximum jamming efficiency,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,automatic telephone answering machine,here is the circuit showing a smoke detector alarm..
