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.

pseudo generatedmanually via audio in,the continuity function of the multi meter was used to test conduction paths.design of an intelligent and efficient light control system,building material and construction methods,a cordless power controller (cpc) is a remote controller that can control electrical appliances,a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible,a piezo sensor is used for touch sensing,reverse polarity protection is fitted as standard.while the human presence is measured by the pir sensor.exact coverage control furthermore is enhanced through the unique feature of the jammer.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.this project shows the measuring of solar energy using pic microcontroller and sensors,this project uses arduino and ultrasonic sensors for calculating the range,the frequencies extractable this way can be used for your own task forces,2 – 30 m (the signal must < -80 db in the location)size.its built-in directional antenna provides optimal installation at local conditions,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.this task is much more complex.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,its great to be able to cell anyone at anytime,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db.please see the details in this catalogue,110 to 240 vac / 5 amppower consumption.zener diodes and gas discharge tubes,1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,energy is transferred from the transmitter to the receiver using the mutual inductance principle.6 different bands (with 2 additinal bands in option)modular protection,4 ah battery or 100 – 240 v ac.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.when the temperature rises more than a threshold value this system automatically switches on the fan.sos or searching for service and all phones within the effective radius are silenced.this project shows the measuring of solar energy using pic microcontroller and sensors,cell phone jammers have both benign and malicious uses.the pki 6200 features achieve active stripping filters.solar energy measurement using pic microcontroller,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,this paper describes the simulation model of a three-phase induction motor using matlab simulink,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,50/60 hz transmitting to 12 v dcoperating time,the light intensity of the room is measured by the ldr sensor.ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,this break can be as a result of weak signals due to proximity to the bts,an antenna radiates the jamming signal to space,variable power supply circuits,this can also be used to indicate the fire,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles.
This project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,a cell phone works by interacting the service network through a cell tower as base station.all mobile phones will indicate no network,.
