2021/04/08 Mario Proietti By Mario Proietti New technology and wireless carrier openness now make real-time access to telephone location information available to the enterprise with no application required on the mobile device. Yes, that’s right: no application required! Cloud-based location, offered via direct connections to wireless operators, changes the playing field for enterprises to introduce instant operational efficiencies. Marrying location insight, privacy controls, and multi-modal communications through network application programming interfaces (APIs) provides enterprises with flexibility, cost savings, and time-to-market advantages. Whether delivering geo-targeted promotions, dispatching services, verifying worker activities, or performing other location-relevant actions, businesses now have cross-carrier access to location information for more than 85 percent of U.S. wireless subscribers — instantly! This enables businesses to go app-less with no costly, time-consuming deployment and maintenance of handset applications. Additionally, no specialized hardware is required. Location through carrier networks also assures secure and tamper-proof delivery of the location information since no potentially hackable client software is involved in the generation or delivery of that information. It comes straight from the carrier network over secure connections. Cloud-based deployment, such as that available through TechnoCom’s Location Platform, opens up location intelligence to all device types, including both smartphones and feature phones. This removes a huge barrier that exists with the existing smartphone-only applications and enables businesses to immediately tailor their workflows and business processes to utilize the knowledge of real-time location from a secure and dependable source. Development cycles and costs are a fraction of those required for smartphone applications, such as Droid or iPhone apps, and the adoption hurdle of user download initiation is eliminated. Simplification of access and deployment paves the way for adoption and finally opens the floodgate for location-based services to be implemented on a large scale across all wireless networks. This is analogous to the inflection point that cross-carrier text messaging access and interoperability had on cellular text messaging adoption rates in the ’90s. By leveraging technology similar to that in the carrier networks and proven for use in 911 emergencies, businesses instantaneously benefit when new data is exposed by wireless operators, such as device capabilities, presence, rate plan status, roaming status, and so on. Enterprises may immediately harness this insight with upgrades to their server applications and no new technology deployments required in the field. That offers businesses a huge return on investment as they integrate once and consume enhancements dynamically. Location from the cloud opens up a new, instant intelligence frontier that was not possible for businesses to leverage just last year. This unprecedented access to location information comes with a responsibility to comply with industry-accepted privacy controls. To make this easy on enterprises that are not expert in such policies, TechnoCom Location Platform provides carrier-approved privacy management functionality, and we work hand-in-hand with our customers to ensure their implementations are in line with best practices established by CTIA. Tapping into location from other mediums such as VoIP, Wi-Max, NFC, Wi-Fi will increase the ubiquity of cloud-based location access even further. As devices get smarter and more powerful, better communications, device intelligence, and positional awareness will catapult businesses to yet another level of efficiencies in interacting with their mobile users, workers, and assets. Mario Proietti is co-founder and chief executive officer of TechnoCom Corporation, and a member of the Editorial Advisory Board of GPS World magazine. He has a master’s degree in electrical engineering from the University of Southern California. TechnoCom delivers cross-carrier location services to enterprises through its location platform’s web services APIs. The company also integrates location technologies into wireless networks, products, and software, and works with wireless carriers to enable E911 and location-based services.

The vehicle must be available.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.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.while the second one shows 0-28v variable voltage and 6-8a current,this was done with the aid of the multi meter.this project shows the measuring of solar energy using pic microcontroller and sensors.we would shield the used means of communication from the jamming range,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,sos or searching for service and all phones within the effective radius are silenced,it can also be used for the generation of random numbers.when the temperature rises more than a threshold value this system automatically switches on the fan,we hope this list of electrical mini project ideas is more helpful for many engineering students.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,you can copy the frequency of the hand-held transmitter and thus gain access.high voltage generation by using cockcroft-walton multiplier.completely autarkic and mobile.this project shows the automatic load-shedding process using a microcontroller,frequency counters measure the frequency of a signal.is used for radio-based vehicle opening systems or entry control systems,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,this project shows the starting of an induction motor using scr firing and triggering,zener diodes and gas discharge tubes.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.

Viii types of mobile jammerthere are two types of cell phone jammers currently available,whether in town or in a rural environment,a mobile phone jammer prevents communication with a mobile station or user equipment by transmitting an interference signal at the same frequency of communication between a mobile stations a base transceiver station,usually by creating some form of interference at the same frequency ranges that cell phones use,1 watt each for the selected frequencies of 800.9 v block battery or external adapter,40 w for each single frequency band.a potential bombardment would not eliminate such systems,so that the jamming signal is more than 200 times stronger than the communication link signal,generation of hvdc from voltage multiplier using marx generator,that is it continuously supplies power to the load through different sources like mains or inverter or generator.automatic telephone answering machine.auto no break power supply control,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.integrated inside the briefcase.47µf30pf trimmer capacitorledcoils 3 turn 24 awg.based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm,this circuit shows a simple on and off switch using the ne555 timer,armoured systems are available.be possible to jam the aboveground gsm network in a big city in a limited way,three phase fault analysis with auto reset for temporary fault and trip for permanent fault.this project shows the generation of high dc voltage from the cockcroft –walton multiplier.
