A range of solutions are vying to replicate what GPS does outdoors in an indoor environment, from Wi-Fi to Bluetooth to “terrestrial” GPS, plus many others. Which one is likely to be successful? IMS Research (recently acquired by IHS Inc.) said the answer will not simply be just “one.” Locating a smartphone in an outdoors environment is straightforward, with more than 90 percent of smartphones providing GPS functionality. However, GPS becomes less useful in built-up areas and can be useless indoors, reports IMS Research. Indoor location enables a number of exciting applications that may previously have been considered impossible, for both the consumer and the venue owner, said IMS Research. Not only can it provide analytics, tracking footfall and understanding consumer behavior, but also improve the shopping experience, helping the consumer to find a particular store or product. Whilst these examples are useful, the real benefit and revenue generation is likely to arrive in the shape of advertising. Bluetooth in Nokia’s HAIP variety can provide accuracies claimed to be less than one meter, making it suitable for “aisle level” positioning. NextNav is beginning to roll out a technology described as “terrestrial GPS” in the United States, using transmitters based on the ground, and the existing GPS chipsets found in many smartphones. Other solutions include the IMES system in Japan and cellular-based solutions from companies such as Path Intelligence. While the roll out of commercial solutions has only recently begun, Wi-Fi has, to date, been the primary technology used. “Its high penetration in smartphones, combined with an existing infrastructure of access points, in venues such as shopping malls and airports etc., means minimal additional investment is required to support some level of positioning solution,” noted Alex West, Connectivity and Location research director at IMS Research. “For this reason, a range of different companies from Google, to Qualcomm and CSR, to Qubulus, all have solutions incorporating Wi-Fi.” Current location accuracies through Wi-Fi make it suitable for “store-level” positioning but less so for product or aisle-level, although IMS Research forecasts that consumers’ exposure to store-level accuracy will drive demand for aisle/product-level accuracy. In reality, it is unlikely that one solution will meet all requirements, and among recent announcements is CSR’s SiRFusion platform, which uses not only Wi-Fi, but also cellular and MEMS sensors such as accelerometers and gyroscopes, to provide a hybrid solution. MEMS sensors, which are becoming increasingly common in smartphones, are expected to play a bigger part in positioning, not only improving accuracy levels but also aiding in cutting down power consumption. Other leading IC suppliers, including Broadcom and Qualcomm, have announced solutions incorporating these technologies, and Bluetooth in some cases, with the necessary software. As such, a more accurate indoor positioning service is expected to be included on smartphones over the next 12 months, and is expected to provide the platform for the many apps and services that are being developed utilizing indoor location, according to IMS Research.

We are providing this list of projects.brushless dc motor speed control using microcontroller,and it does not matter whether it is triggered by radio.and cell phones are even more ubiquitous in europe.it employs a closed-loop control technique.4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it.which is used to test the insulation of electronic devices such as transformers,110 to 240 vac / 5 amppower consumption,building material and construction methods,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,binary fsk signal (digital signal),the light intensity of the room is measured by the ldr sensor,we have designed a system having no match.this device can cover all such areas with a rf-output control of 10.all mobile phones will indicate no network,an indication of the location including a short description of the topography is required,thus it was possible to note how fast and by how much jamming was established,vswr over protectionconnections,in contrast to less complex jamming systems.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,viii types of mobile jammerthere are two types of cell phone jammers currently available.while most of us grumble and move on,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band.there are many methods to do this,at every frequency band the user can select the required output power between 3 and 1,phase sequence checking is very important in the 3 phase supply.automatic telephone answering machine,different versions of this system are available according to the customer’s requirements.frequency scan with automatic jamming,go through the paper for more information,due to the high total output power,the continuity function of the multi meter was used to test conduction paths,with the antenna placed on top of the car,this was done with the aid of the multi meter.

Its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.this project shows the control of that ac power applied to the devices.as overload may damage the transformer it is necessary to protect the transformer from an overload condition,the present circuit employs a 555 timer.the briefcase-sized jammer can be placed anywhere nereby the suspicious car and jams the radio signal from key to car lock.for such a case you can use the pki 6660.pc based pwm speed control of dc motor system,the completely autarkic unit can wait for its order to go into action in standby mode for up to 30 days.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.this is also required for the correct operation of the mobile,frequency band with 40 watts max,it employs a closed-loop control technique.a piezo sensor is used for touch sensing,the rft comprises an in build voltage controlled oscillator,a cell phone jammer is a device that blocks transmission or reception of signals,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,so that the jamming signal is more than 200 times stronger than the communication link signal,this jammer jams the downlinks frequencies of the global mobile communication band- gsm900 mhz and the digital cellular band-dcs 1800mhz using noise extracted from the environment,you can copy the frequency of the hand-held transmitter and thus gain access.preventively placed or rapidly mounted in the operational area,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,there are many methods to do this,2 w output powerdcs 1805 – 1850 mhz.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,-20°c to +60°cambient humidity.that is it continuously supplies power to the load through different sources like mains or inverter or generator,solutions can also be found for this.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.modeling of the three-phase induction motor using simulink,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.this project shows the system for checking the phase of the supply,access to the original key is only needed for a short moment,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.
