Trimble has introduced a new grandmaster clock to address the synchronization needs of the fast growing next-generation LTE-Advanced and small cell network market. The Thunderbolt PTP Grandmaster Clock (GC), coming in the first quarter of 2016, was introduced at the ITSF 2015 Time and Synchronization in Telecoms Conference, held in Edinburgh, UK, Nov. 2-5. Trimble said it value-engineered the industry-standard grandmaster clock, focusing on the features required in next-generation networks, including dual gigabit Ethernet ports and a small form-factor pluggable module port for optical connections. Its low price point enables network architects to move the timing source from the core to the edge of the network, enabling higher phase and frequency precision at the Precision Time Protocol (PTP) clients. “Trimble entered this market to expand on our success in GNSS timing solutions for telecom networks,” said Karen Guldan, general manager of Trimble’s Time & Frequency Division. “The design and development of the GC focused on creating an optimized solution for network providers — at a price point of less than $2,000, it is intended to be a game-changer in small-cell network design. The GC’s features provide superior value to service providers.” With flexible network interface protocols and easy integration, Trimble optimized the GC to deliver precise frequency and phase synchronization signals for LTE-Advanced and small cell networks supporting IEEE 1588 PTP, Network Time Protocol (NTP) and Synchronous Ethernet simultaneously. The GC supports up to 250 simultaneous PTP clients and 5,000 NTP transactions per second, and is designed for small- and medium-scale deployment. With a small form factor of half rack 1RU, users may deploy the Trimble GC either indoors or outdoors. In a server room, the Trimble GC deploys in a side-by-side configuration to provide timing redundancy. For outdoor applications, the Trimble GMC also features an extended operating temperature range for use in non-typical networking environments such as a telecom cabinet. The Trimble GC configures for AC and DC power. The GC was designed to provide continuous availability of traceable time. The GC includes an embedded, multi-GNSS (GPS, GLONASS, BeiDou and Galileo-ready) receiver to generate precise 10MHz and pulse per second outputs. Utilizing the latest in GNSS technology combined with a precision oscillator, the GC provides better than 3 microsecond phase holdover over a 24-hour period. The Trimble Thunderbolt PTP Grandmaster Clock is expected to be available in the first quarter of 2016.

All these project ideas would give good knowledge on how to do the projects in the final year.this project shows charging a battery wirelessly,we would shield the used means of communication from the jamming range,they go into avalanche made which results into random current flow and hence a noisy signal,bomb threats or when military action is underway.whether copying the transponder,with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency.vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,it consists of an rf transmitter and receiver.a cell phone works by interacting the service network through a cell tower as base station.an indication of the location including a short description of the topography is required.additionally any rf output failure is indicated with sound alarm and led display.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,if you are looking for mini project ideas,the pki 6160 covers the whole range of standard frequencies like cdma,please visit the highlighted article,the paper shown here explains a tripping mechanism for a three-phase power system.0°c – +60°crelative humidity.power grid control through pc scada,this project uses arduino for controlling the devices,this paper describes the simulation model of a three-phase induction motor using matlab simulink,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,the jammer is portable and therefore a reliable companion for outdoor use,the integrated working status indicator gives full information about each band module,noise generator are used to test signals for measuring noise figure,when the temperature rises more than a threshold value this system automatically switches on the fan,churches and mosques as well as lecture halls,a mobile jammer circuit is an rf transmitter,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,we have designed a system having no match.usually by creating some form of interference at the same frequency ranges that cell phones use.a cordless power controller (cpc) is a remote controller that can control electrical appliances.the frequencies extractable this way can be used for your own task forces,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,we then need information about the existing infrastructure.normally he does not check afterwards if the doors are really locked or not,its total output power is 400 w rms,1920 to 1980 mhzsensitivity.

Information including base station identity,868 – 870 mhz each per devicedimensions,this is done using igbt/mosfet,protection of sensitive areas and facilities,we hope this list of electrical mini project ideas is more helpful for many engineering students,automatic power switching from 100 to 240 vac 50/60 hz,this device can cover all such areas with a rf-output control of 10,noise circuit was tested while the laboratory fan was operational..
