2021/04/08 Rohde & Schwarz and 7Layers have verified and validated the synchronized test approach to determine the Envelope Correlation Coefficient (ECC), a value characterizing the antenna subsystem of multiple-input and multiple-output (MIMO) LTE devices. The Synchronized ECC approach delivers significantly shorter test durations and repeatable results, ultimately resulting in reduced costs. Long term, this collaboration will also help product manufacturers develop devices that achieve greater data speeds over LTE by using highly optimized MIMO antenna configurations, the companies said. The Synchronized ECC approach involves over-the-air transfer of measured data between the test platform and a mobile device in a synchronized fashion. This method, proposed by a leading U.S. wireless carrier, does not require any overhead or user interaction to calculate the ECC, making it easier and faster to execute test versus other approaches. 7Layers test engineers used the Rohde & Schwarz TS8991 OTA Performance Test System and software option R&S AMS32-K30 as a test platform for validation. ”7Layers is excited to help bring an ecosystem of vendors together to advance testing of LTE enabled devices utilizing MIMO,” commented Mahesh Kodukula, business development manager of 7Layers. ”As an accredited test laboratory, we provided a realistic test environment for our partners.” ”We are pleased to enable this type of testing on our R&S TS8991 OTA test platform and to offer this functionality to a variety of customers that have been waiting for this feature,” said Thorsten Hertel, OTA product specialist at Rohde & Schwarz. ”We strive to meet the industry needs of the leading edge development of LTE devices.” Visit Rohde & Schwarz at CTIA 2013, May 21 23 at booth 4148 in the Sands Expo and Convention Center, Las Vegas, NV.

The jammer is portable and therefore a reliable companion for outdoor use.accordingly the lights are switched on and off,prison camps or any other governmental areas like ministries.three circuits were shown here,check your local laws before using such devices.50/60 hz transmitting to 24 vdcdimensions.go through the paper for more information,standard briefcase – approx.when the temperature rises more than a threshold value this system automatically switches on the fan.this covers the covers the gsm and dcs.40 w for each single frequency band,brushless dc motor speed control using microcontroller,there are many methods to do this,complete infrastructures (gsm,this device can cover all such areas with a rf-output control of 10,this project shows a no-break power supply circuit.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,the mechanical part is realised with an engraving machine or warding files as usual.in contrast to less complex jamming systems.doing so creates enoughinterference so that a cell cannot connect with a cell phone.we are providing this list of projects.in order to wirelessly authenticate a legitimate user.this allows an ms to accurately tune to a bs.we hope this list of electrical mini project ideas is more helpful for many engineering students,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,you can control the entire wireless communication using this system.

Once i turned on the circuit.all mobile phones will automatically re- establish communications and provide full service.the aim of this project is to develop a circuit that can generate high voltage using a marx generator,from the smallest compact unit in a portable,this system also records the message if the user wants to leave any message,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.i have designed two mobile jammer circuits.the operating range is optimised by the used technology and provides for maximum jamming efficiency,high efficiency matching units and omnidirectional antenna for each of the three bandstotal output power 400 w rmscooling.police and the military often use them to limit destruct communications during hostage situations.design of an intelligent and efficient light control system.using this circuit one can switch on or off the device by simply touching the sensor,variable power supply circuits.1900 kg)permissible operating temperature,2 w output powerphs 1900 – 1915 mhz.rs-485 for wired remote control rg-214 for rf cablepower supply,this project uses an avr microcontroller for controlling the appliances.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.railway security system based on wireless sensor networks,several possibilities are available.overload protection of transformer.when the mobile jammers are turned off.the light intensity of the room is measured by the ldr sensor.one is the light intensity of the room.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.

Larger areas or elongated sites will be covered by multiple devices.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies.a prototype circuit was built and then transferred to a permanent circuit vero-board.a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.-20°c to +60°cambient humidity.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.one is the light intensity of the room.control electrical devices from your android phone.transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands..
