#NIST Develops 16-Antenna Array for Modeling of Wireless communications Channels at 83ghz To help solve the wireless crowding conundrum
and support the next generation of mobile technology--5g cellular--researchers at the National Institute of Standards and Technology (NIST) are developing measurement tools for channels that are new for mobile communications
and that could offer more than 1000 times the bandwidth of today's cell phone systems. Like pioneers who found land by going west telecom researchers can find open spectrum by going up--to higher frequencies.
Mobile devices such as cell phones consumer Wifi devices and public safety radios mostly operate below 3 gigahertz (GHZ)( see infographic.
But some devices are starting to use fast silicon-germanium radio chips operating at millimeter (mm) wavelengths above 10 GHZ.
Researchers at NIST and elsewhere are eyeing channels up to 100 GHZ and even beyond. The metrology infrastructure for telecommunications at these frequencies is incomplete.
NIST's challenge is to develop tools and test methods that are far more precise than today's versions to optimize device performance.
Because high-speed digital circuits can easily distort mm wave signals even tiny errors can result in erroneous bits of information.
Possible solutions include development of complex antenna arrays that may provide novel capabilities such as beam steering--the capability to transmit in many different directions to point the beam directly at the receiving device and even track mobile devices.
This work can advance the state of the art in telecommunications and help meet the expected increases in demand for wireless capacity.
So far Remley and her colleagues have developed a calibrated modulated signal source to test mm wave instruments such as receivers
*and channel sounders to support modeling of mm wave communications channels in indoor and outdoor environments.
Other NIST researchers have demonstrated a new probe for making the first calibrated measurements of electric fields above 100 GHZ
**and a new facility for characterizing antennas operating above 100 GHZ.*****The new calibrated signal source demonstrated at 44 GHZ
so that companies and other users can easily put together their own systems. The mobile channel sounder demonstrated at 83 GHZ so far provides calibrated received signal strength
and additional data for analysis of signal scattering and reflections to help researchers develop network protocols that account for distortions.
As part of the same project NIST researchers are also developing a millimeter-wave instrument to measure the nonlinear characteristics of the transistors
and amplifiers that will be used in mm wave receivers transmitters and other devices. All of this research is being done in NIST's new Communications technology Laboratory.

such as mobile phones and wireless internet connections, have become an integral part of modern life. However, today devices use twice as much of the radio spectrum as is necessary.
New technology is being developed that could fundamentally change radio design and could increase data rates and network capacity, reduce power consumption,
create cheaper devices and enable global roaming. A pioneering team of researchers from the University of Bristol's Communication systems
and Networks research group, have developed a new technique that can estimate and cancel out the interference from one own transmission,
Leo Laughlin, a Phd student from the University EPSRC Centre for Doctoral Training (CDT) in Communications, together with MSC student Chunqing Zhang, supervisors Professor Mark Beach and Dr Kevin Morris,
and built a novel full-duplex transceiver architecture, which combines electrical balance isolation and active radio frequency cancellation.
Their prototype can suppress interference by a factor of over 100 million and uses low-cost
small form factor technologies, making it well suited to use in mobile devices such as smartphones and tablets.
In Wi-fi systems this would double the capacity of a Wi-fi access point, allowing more users and higher data rates.
For cellular systems, full-duplex operation would also deliver increased capacity and data rates, or alternatively the network operators could provide the same total network capacity with fewer base station sites,
giving obvious benefits in the cost and environmental impact of running the network. Leo Laughlin who is in the first cohort of students in the CDT in Communications,
said: ntil now there has been unsolved a fundamental problem with radio communication. Since the radio spectrum is limited a resource,
and with network operators paying billions of pounds to access the spectrum, solving this problem would bring us one step closer to the faster, cheaper and greener devices of our connected future.
As well as being part of the evolution to 5g mobile, this research is also very relevant to the design of the radio circuitry in current 3g and 4g cellular mobile devices.
In today mobile devices, a separate filtering component is required for each frequency band and because of this, today mobiles phone do not support all of the frequency channels
which are in use across the world. Different devices are manufactured for different regions of the world,
and there are currently no 4g phones capable of unrestricted global roaming. Replacing these filters with the research team duplexer circuit would create smaller and cheaper devices,
and would allow manufacturers to produce a single model for the entire world. This would enable global roaming on 4g
and would further decrease cost through greater economies of scale. Mark Beach, Professor of Radio Systems Engineering
commented: n addition to EPSRC investment in Doctoral Training Centres at Bristol, we have also been awarded equipment funding.
Leo and Chunqing have taken full advantage of the new laboratory facilities in the validation and optimisation of our full-duplex architecture.
The team have published papers about their research in the IEEE Journal on Selected Areas in Communications special issue on full duplex radio,
and in this month issue of the IEEE Communications Magazine, and patents have been filed to protect the novel duplexer design.

#Portable, Autonomous Device Analyzes Trace elements in Water, Air and Upper atmosphere Researchers from Arizona State university School of Earth and Space exploration have combined their sensors,
biotechnology and instrumentation expertise to develop a portable, autonomous device that analyzes trace elements. The highly miniaturized microbial analysis machine,
called the ddpcr Bioanalytical Field Instrument, allows researchers to do things such as detect microbes in water,
Developed by a team led by experimental physicist Cody Youngbull, assistant research professor in the School of Earth and Space exploration,
the technology was intended originally for deployment on an Autonomous Underwater Vehicle platform as part of a project to map the dynamic microbial diversity in the world oceans.
After four years of development and millions of dollars from the Gordon and Betty Moore Foundation, the National Science Foundation and the Monterey Bay Aquarium Research Institute, the instrument is now operational.
The data is quantified then directly in the field for immediate feedback. The small droplets enable the device to produce millions of copies of any specified DNA sequence in minutes.
With the emergent capability to perform this sort of analysis on an autonomous underwater vehicle the device is quite adaptable to the needs of the researcher
including the built environment. According to Youngbull, while it does have health applications since it is able to quantify pathogens,
he doesn see it as a medical diagnostic tool. t designed for exploration, he said. eing able to detect trace components, single molecules, autonomously and reliably, without the need for sample return or hardware consumables in a really tiny,
low-power package are what our machine is all about. lthough there may be limited medical diagnostic applications,
Youngbull envisions use of the device in homeland security, mass transit, public spaces, hospitals, schools, food production and combat theater analytics.
Autonomous, digital droplet PCR is useful for many aspects of science. The device might even one day be integrat ed into a rover,
lander or orbiter to seek out extant DNA in the water on Mars, the oceans of Europa,
and quantify nucleic acid sequences. Source: http://www. asu. edu
#Researcher Integrates"Motherboard"in Textiles for Determining Sleep Cycles The specialist in infrared physics found a way for the technology to reach the majority of the population,
and found that textiles are used most, so he decided to turn them intelligent. The entrepreneur exemplifies that he can"integrate"in the sheets or bedspreads a card with sensors capable of measuring sleep cycles."
"In particular, the technology would be aimed at people who suffer from depression and are under medical treatment
because it will be an effective tool to know how many hours of sleep the patient is getting."
which via radio frequency sends"monitoring or results"to the doctor or specialist. He adds that as innovation is noninvasive,
and was granted half a million dollars for development and validation of prototypes.""As the park has great business structuring
and variety of smartphones and other connected devices keeps growing, the need for radio spectrum grows with it.
Cognitive radio technology developed under the EU-funded QOSMOS project could help meet these needs
while controlling telecom costs, improving service and driving the development of new markets. In the near future, the telecom industry will be faced with three challenges:
a need for more radio spectrum, an ever-increasing demand for data, and consumersincreasing unwillingness to pay for it.
Spectrum, however, is a finite resource. The QOSMOS project addressed the twin problems of scarcity and cost by developing cognitive radio technology that dynamically optimises the use of radio spectrum,
by accessing under-utilised portions of the spectrum and sharing spectrum across devices. he idea is to break down silos,
says Michael Fitch of British telecom, who coordinated the QOSMOS project. very new service and technology needs a new spectrum,
and silos are formed when there are umpteen different devices that use umpteen different parts of the spectrum.
This diversity does not make for efficient spectrum management. The project partners therefore developed three technologies:
a resource manager that allocates the spectrum to individual systems and senses the environment; and a cognitive radio terminal.
The project also developed a prototype transceiver to generate FBMC (Filter Bank Multicarrier transmission) waveforms.
An early pilot led by UK telecommunications regulator Ofcom, for example, would use some of the technology developed in QOSMOS to access TV white spaces,
which are unused spaces in the UHF band allocated to TV broadcasters. Without intelligent spectrum management, interference by econdary spectrum userscould degrade broadcast quality for viewers. voiding interference calls for more spectrum management,
says Fitch. nd it not just a case of choosing the optimum spectrum, but also the appropriate waveform.
A home automation sensor, for example, may periodically transmit state information with a low data requirement,
while a television set top box may require much higher bandwidth and more complex spectrum management.
The project culminated in events hosted by BT in the United kingdom and Microsoft in Washington
The Commissariat à lnergie Atomique in France is continuing development work on the FBMC transceiver and several consortium members are likely to commercialise the spectrum manager technology.
Meanwhile, according to Fitch, UK regulator Ofcom is in position to commercialise TV white spaces from 2015.
#Ultrafast Line Scan Sensor from Fraunhofer Identifies Faulty Safety Features in Banknotes In the first half 2014 alone,
nearly 25,000 counterfeit euro notes worth EUR 1. 5 million were registered, according to information by the Deutsche bundesbank.
In order to make the criminal work of counterfeiters more difficult, banknotes are equipped with special security features.
These include tiny structures that are not visible to the naked eye, such as holograms with a tilt effect.
Through the use of special cameras, quality checks during printing are intended to ensure that these features are free of errors on each banknote.
The AIT Austrian Institute of technology is a leader in the international market in the production of such test systems for security printing.
For the development of a new sensor, the Austrian research institution has brought the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg on board.
This is because the sensors which are currently available have reached meanwhile their limits: their speed is often not enough to check quality in real-time during the production process.
Camera takes 200,000 color images per secondwith the 60-line sensor that the Duisburg experts have developed,
ur sensor is twice as fast as currently available solutions, while providing high-quality images in very high resolution, explains Werner Brockherde from the IMS.
The sensor detects the bills like a scanner does line by line when they come off the press.
Software compares the recorded images to a desired image and identifies banknotes with faulty safety features.
In order to achieve the high speed, the IMS researchers have integrated an individual readout chain on the chip for each pixel column.
In addition they have developed special photo pixels, thanks to which conventional optics can be used, despite the short exposure times.
In each pixel column, the three colors red, green and blue are recorded at the same time and over the entire pixel area.
This allows high-quality color reproduction. Another special feature of the sensor is that the high number of lines makes it possible to detect objects from different perspectives. s a result, surface structures in 3d,
such as the tilt effects of holograms, can also be checked for the first time, says Brockherde. The special architecture of the sensor opens up room for further applications.
Thanks to the large number of lines its wavelength spectrum can still be expanded up to the UV or infrared light range.
That would be interesting for the recycling of plastics, as well, where the sensor could identify shredded materials according to their color information,
thereby facilitating separation. With the ability to analyze 3d surfaces, it is also suitable for the quality control of different materials in industrial production.
Even at a speed of around 300 km h, the sensor could provide razor-sharp images with a resolution of up to 0. 4 mm and,
which are equipped with such a sensor and which orbit the Earth at a speed of 26,000 kilometers per hour, could take color photographs of the earth surface with a resolution of 3 centimeters.
The market launch of the new sensor which is at the heart of the AIT test camera is scheduled for the end of 2015.
#Planetiq Commences Testing of"Pyxis"Satellite Weather Sensor Technology"Weather has an immense human and societal impact and affects businesses on a daily if not hourly basis,
and the key is more high-quality weather data.""Pyxis will track GPS signals traveling through Earth's atmosphere and convert them into dense, precise measurements of global temperature,
pressure and water vapor similar to data collected by weather balloons but on a global scale using a technique called GPS Radio Occultation (GPS-RO).
Pyxis is the only GPS-RO sensor in such a small package that is powerful enough to routinely probe down into the lowest layers of the atmosphere where severe weather occurs.
In addition, Pyxis is able to track signals from all four major satellite navigation systems (GPS, Galileo, Beidou and GLONASS.
Planetiq's microsatellite constellation, with an initial set of 12 satellites launching in 2016 and 2017, will deliver over 8 million observations per day of temperature, pressure and water vapor,
or more than 10 times the amount of data available from GPS-RO sensors currently on orbit.
GPS-RO has shown the highest impact per observation on forecast accuracy among the satellite data sources ingested into computer weather models,
and is particularly effective at improving predictions of high-impact weather such as hurricanes, severe weather outbreaks and winter storms.
However, the amount of GPS-RO data available to date has been sparse. The Pyxis sensor development team is based in Boulder
Colo.,, and led by Planetiq Founder Chris Mccormick, who was instrumental in designing the sensors on the U s.-Taiwan Constellation Observing System for Meteorology, Ionosphere,
and Climate (COSMIC), the world's first and only satellite constellation of proven GPS-RO sensors."
"The Earth's atmosphere is sampled radically under at present especially over the oceans which cover 70%of the Earth's surface.
With the speed of innovation in sensor technology, space hardware and launch, the weather forecast will dramatically change for the better in the near future,
"Mccormick said.""The Pyxis represents a major step forward in improving forecast accuracy for both routine weather and big storms,
