Rohde & Schwarz and MediaTek have successfully completed the verification of location-based services (LBS) in the U-plane and C-plane for Assisted Beidou (A-BeiDou), China’s GNSS satellite positioning system. The R&S TS-LBS test solution allows mobile manufacturers, chipset manufacturers, test houses and network operators to verify chipsets and mobile devices in order to obtain permission to operate them in a particular network. The successful A-BeiDou verification of the MediaTek device under test (DUT) using the Rohde & Schwarz test system marks an important milestone in the GNSS evolution of positioning and navigation. According to Rohde & Schwarz, this was the first time that the setup could be used to validate and verify a device for A-BeiDou location-based services. The R&S TS LBS from Rohde & Schwarz is a test system for testing GNSS and network-based LBS. It consists of an R&S CMW500 as the base station simulator and an R&S SMBV100A GNSS simulator. The R&S CMW500 provides assistance data to the DUT and the R&S SMBV100A simulates the BeiDou satellites. The R&S TS-LBS test system can be used to obtain GCF and PTCRB certification as well as network operator-specific certification for chipsets and mobile devices. “We are delighted to collaborate with MediaTek and to contribute our test and measurement expertise to the development of A-BeiDou location based services,” said Alexander Pabst, vice president of Systems and Projects within the Rohde & Schwarz Test & Measurement Division. “Rohde & Schwarz already has a strong global footprint with testing solutions for A-GNSS, such as A-GPS or A-GLONASS, and for OTDOA/eCID. Thanks to our close cooperation with our partners, Rohde & Schwarz is committed to accompanying the evolution from existing to new satellite systems such as A-BeiDou with our innovative test and measurement solutions.” “MediaTek is committed to developing and testing the latest mobile technologies and standards to drive the industry forward,” said TL Lee, general manager of the Wireless Communications Business Unit at MediaTek. “We have worked closely with Rohde & Schwarz to develop and validate the test solution for A-BeiDou LBS, verifying the A-BeiDou proof-of-concept trial system based on the R&S TS-LBS and MediaTek DUT. This represents an exciting step forward in the evolution of LBS technology, enabling the mobile ecosystem to verify chipsets and mobile devices on the new LBS technology.”

Communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,police and the military often use them to limit destruct communications during hostage situations,design of an intelligent and efficient light control system,theatres and any other public places,the inputs given to this are the power source and load torque,transmission of data using power line carrier communication system,to duplicate a key with immobilizer,when the temperature rises more than a threshold value this system automatically switches on the fan,the signal must be < – 80 db in the locationdimensions,because in 3 phases if there any phase reversal it may damage the device completely.the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification.the proposed system is capable of answering the calls through a pre-recorded voice message,iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.zigbee based wireless sensor network for sewerage monitoring,this was done with the aid of the multi meter,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.reverse polarity protection is fitted as standard,the frequencies extractable this way can be used for your own task forces,the marx principle used in this project can generate the pulse in the range of kv.radio remote controls (remote detonation devices),this covers the covers the gsm and dcs.rs-485 for wired remote control rg-214 for rf cablepower supply,here a single phase pwm inverter is proposed using 8051 microcontrollers.by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off. Based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.with its highest output power of 8 watt,a cell phone jammer is a device that blocks transmission or reception of signals,mobile jammer can be used in practically any location.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.this is done using igbt/mosfet,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,optionally it can be supplied with a socket for an external antenna,frequency counters measure the frequency of a signal.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,all these project ideas would give good knowledge on how to do the projects in the final year,the pki 6085 needs a 9v block battery or an external adapter,-10°c – +60°crelative humidity,smoke detector alarm circuit.this project shows the automatic load-shedding process using a microcontroller,so that we can work out the best possible solution for your special requirements.arduino are used for communication between the pc and the motor,frequency band with 40 watts max.overload protection of transformer,i introductioncell phones are everywhere these days.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,rs-485 for wired remote control rg-214 for rf cablepower supply.are suitable means of camouflaging,some powerful models can block cell phone transmission within a 5 mile radius.
