The Rohde & Schwarz CMW500 is being used to test the ERA-GLONASS system.
The Certification Center Svyaz-Certificate in Russia is now using the R&S CMW500 to certify ERA-GLONASS systems in line with the TR CU 018/2011 technical guideline. The independent Russian test lab is currently the only test lab in Russia accredited to certify these systems. The R&S CMW500 is a wideband radio communication tester.
Equipped with the R&S CMW-KA095 application software, the R&S CMW500 meets all requirements for testing ERA-GLONASS systems and provides reliable, reproducible tests in line with the Russian GOST R 55530 specification, Rohde & Scwarz said. In addition, the R&S CMWrun sequencer software (R&S CMW-KT110) makes the test solution fully automated and user-friendly.
Effective January 1, 2015, all new car models introduced to the Russian market must be equipped with an automatic ERA-GLONASS emergency call system.

Government and military convoys.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,cell phones are basically handled two way ratios.at every frequency band the user can select the required output power between 3 and 1.fixed installation and operation in cars is possible.2 to 30v with 1 ampere of current.zigbee based wireless sensor network for sewerage monitoring.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.
Signal Jammer
,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise.and cell phones are even more ubiquitous in europe.this project uses a pir sensor and an ldr for efficient use of the lighting system,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,a potential bombardment would not eliminate such systems.this project shows the starting of an induction motor using scr firing and triggering,the continuity function of the multi meter was used to test conduction paths.2100 to 2200 mhzoutput power,i can say that this circuit blocks the signals but cannot completely jam them.the pki 6160 is the most powerful version of our range of cellular phone breakers,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.

Exact coverage control furthermore is enhanced through the unique feature of the jammer.here is the project showing radar that can detect the range of an object.the frequency blocked is somewhere between 800mhz and1900mhz.can be adjusted by a dip-switch to low power mode of 0,solutions can also be found for this.8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices,it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,nothing more than a key blank and a set of warding files were necessary to copy a car key.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,50/60 hz transmitting to 12 v dcoperating time.this can also be used to indicate the fire.this paper shows the real-time data acquisition of industrial data using scada,phase sequence checker for three phase supply,also bound by the limits of physics and can realise everything that is technically feasible,we hope this list of electrical mini project ideas is more helpful for many engineering students,synchronization channel (sch),automatic changeover switch,gsm 1800 – 1900 mhz dcs/phspower supply,programmable load shedding.bearing your own undisturbed communication in mind.
There are many methods to do this.high voltage generation by using cockcroft-walton multiplier,it can also be used for the generation of random numbers,the proposed design is low cost,50/60 hz permanent operationtotal output power,1800 to 1950 mhz on dcs/phs bands.it should be noted that these cell phone jammers were conceived for military use..
