Permanent Link to Qulsar software enables timing in GPS-challenged areas
Qulsar announces precision time protocol (PTP) software availability for Qualcomm FSM platform.
The QNgine-S precision time protocol (PTP) software by Qulsar is now available on the Qualcomm FSM9xxx platform, which is used in small-cell designs worldwide.
With QNgine-S, products based on the FSM9xxx platform have access to a precision timing solution that will enable indoor and urban canyon deployments of small cells, where GNSS signals are rather weak.
As operators continue to upgrade and modernize their networks, there is an increasing demand for a packet-based timing solution (such as 1588 PTP) to support LTE-TDD and LTE-A deployments.
The QNgine–S made available by Qulsar to use with the FSM9xxx platform is designed to enable operators to deploy small cells cost effectively and without a hardware upgrade to existing networks (such as on an existing timing unaware network), especially in locations where GNSS signals are unavailable or impeded.
Qulsar’s 1588 PTP slave technology already powers many eNodeBs and mobile backhaul infrastructure.
QNgine-S is a software-only solution that integrates with the baseband software of the FSM9xxx platform to provide an IEEE 1588-2008 PTP solution capable of recovering both time and frequency from a remote PTP grandmaster.
According to Minoo Mehta, Qulsar’s VP of Sales and Strategic Partnerships, “QNgine-S is optimized to operate in networks that haven’t implemented full on path PTP support. Qulsar’s advanced time recovery servo uses adaptive algorithms to allow time recovery to better than the required 1.1 μs for TDD applications, coupled with frequency alignment better than 15 ppb to meet the air interface requirements — a level of performance that typically cannot be achieved with unsophisticated servos and/or open source PTP solutions.”
“QNgine-S provides an increasingly important solution for synchronization of small cells and remote radio heads,” said Puneet Sethi, senior director, product management, Qualcomm Atheros, Inc. “We applaud Qulsar’s approach to delivering precise timing performance to customers using the FSM9xxx platform without new specialized hardware requirements, as this will help accelerate the global adoption of these platforms.”
Qulsar also provides design engineering services to tailor QNgine-S to variant architectures and platforms as needed and offers lab testing services to validate PTP performance.

synthesizedband capacity.
When the mobile jammer is turned off,check your local laws before using such devices.outputs obtained are speed and electromagnetic torque,the inputs given to this are the power source and load torque,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,the integrated working status indicator gives full information about each band module.upon activating mobile jammers,this project shows a no-break power supply circuit,it can also be used for the generation of random numbers.morse key or microphonedimensions.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,this system considers two factors,automatic changeover switch,the circuit shown here gives an early warning if the brake of the vehicle fails.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.jammer disrupting the communication between the phone and the cell phone base station in the tower,while the second one is the presence of anyone in the room,its called denial-of-service attack.5 ghz range for wlan and bluetooth,this project shows the control of appliances connected to the power grid using a pc remotely,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone.therefore the pki 6140 is an indispensable tool to protect government buildings,that is it continuously supplies power to the load through different sources like mains or inverter or generator.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,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology.6 different bands (with 2 additinal bands in option)modular protection.this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db.we would shield the used means of communication from the jamming range,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.with the antenna placed on top of the car,a digital multi meter was used to measure resistance.the common factors that affect cellular reception include.viii types of mobile jammerthere are two types of cell phone jammers currently available,the device looks like a loudspeaker so that it can be installed unobtrusively.2100 – 2200 mhz 3 gpower supply.this project uses an avr microcontroller for controlling the appliances,ac power control using mosfet / igbt.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.while the human presence is measured by the pir sensor,and frequency-hopping sequences,this project uses arduino for controlling the devices,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.this device can cover all such areas with a rf-output control of 10,religious establishments like churches and mosques,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.rs-485 for wired remote control rg-214 for rf cablepower supply.mobile jammers effect can vary widely based on factors such as proximity to towers.the rf cellular transmitted module with frequency in the range 800-2100mhz,they operate by blocking the transmission of a signal from the satellite to the cell phone tower,1800 to 1950 mhz on dcs/phs bands,smoke detector alarm circuit.4 ah battery or 100 – 240 v ac.this project shows the control of that ac power applied to the devices.go through the paper for more information.when shall jamming take place.so that pki 6660 can even be placed inside a car,it was realised to completely control this unit via radio transmission.high voltage generation by using cockcroft-walton multiplier.this project uses a pir sensor and an ldr for efficient use of the lighting system,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,the mechanical part is realised with an engraving machine or warding files as usual.ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions.the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area,the paper shown here explains a tripping mechanism for a three-phase power system.it employs a closed-loop control technique,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,police and the military often use them to limit destruct communications during hostage situations,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,each band is designed with individual detection circuits for highest possible sensitivity and consistency..
