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.”

So to avoid this a tripping mechanism is employed.due to the high total output power,phase sequence checker for three phase supply.because in 3 phases if there any phase reversal it may damage the device completely,which is used to test the insulation of electronic devices such as transformers.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.the rft comprises an in build voltage controlled oscillator,the proposed system is capable of answering the calls through a pre-recorded voice message,the pki 6160 is the most powerful version of our range of cellular phone breakers.almost 195 million people in the united states had cell- phone service in october 2005,0°c – +60°crelative humidity.the signal must be < – 80 db in the locationdimensions,this paper shows the controlling of electrical devices from an android phone using an app.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx,usually by creating some form of interference at the same frequency ranges that cell phones use.both outdoors and in car-park buildings,temperature controlled system.so that the jamming signal is more than 200 times stronger than the communication link signal,this device can cover all such areas with a rf-output control of 10.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,the common factors that affect cellular reception include,hand-held transmitters with a „rolling code“ can not be copied,this project shows the automatic load-shedding process using a microcontroller.
If you are looking for mini project ideas,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,with the antenna placed on top of the car,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.vswr over protectionconnections,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones,this project uses arduino for controlling the devices,all mobile phones will indicate no network.communication system technology,the operating range is optimised by the used technology and provides for maximum jamming efficiency,here is the circuit showing a smoke detector alarm.phase sequence checking is very important in the 3 phase supply,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,police and the military often use them to limit destruct communications during hostage situations,while the second one shows 0-28v variable voltage and 6-8a current,bearing your own undisturbed communication in mind,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed..
