it could significantly expand the reach of so-called"super Wi-fi"networks in urban areas.""Due to the popularity of cable, satellite and Internet TV, the UHF spectrum is one of the most underutilized portions of the wireless spectrum in the United states,
"said lead researcher Edward Knightly.""That's a bitter irony because the demand for mobile data services is expected to grow tenfold in the next five years,
and computer engineering and director of the Rice Wireless Network Group, said the UHF spectrum, which ranges from 400 to 700 megahertz,
is called often the"beachfront property"of the wireless spectrum. Unlike the higher frequency signals used for existing Wi-fi hotspots,
UHF signals carry for miles and are blocked not by walls or trees. Because of these advantages, wireless data hotspots that use UHF are referred often to as"super Wi-fi."
"In the U s.,TV broadcasters have been given preferential access to the UHF spectrum for more than 50 years.
"Unfortunately, in the most densely populated areas of the country, where the need for additional wireless data services is the greatest,

or other liquids into the plasma sheath to make it more permeable to radio signals, but these methods require extra power and weight, respectively.
when the electromagnetic fluctuations of radio antennas are in sync with those of their surroundings, a phenomenon known as resonance can amplify radio signals.
One example of resonance is the way a playground swing will climb higher from repeated pushes.
and radio signals could propagate through, they explained. For the resonance to work, the thickness of this matched layer and the plasma sheath must be smaller than the wavelengths of the radio signals used for communication, the scientists noted.
The properties of the plasma sheath can vary during flight, complicating any efforts to generate resonance,

#Researchers Power Small Electronics Using Wi-fi: Clarkson Waves Your Wi-fi router already brings you Netflix and cat pictures,
but someday it might become even more important to your life. A group of researchers from the University of Washington were able to send energy from a Wi-fi router to low power electronics from up to 28 feet away,
without interfering with the router and neighboring routersability to transmit data. They call their technology Power over Wi-fi (Powifi.
Using Atheros chipsets, the researchers made several Powifi routers that worked as normal but also sent meaningless packets of data over multiple 2. 4ghz channels.
They programmed these routers to send these nintrusive power trafficonly when the router isn sending data to connected devices.
They then built four low power devices: a temperature sensor, a camera, a coin battery charger and the AA battery charger shown above.
Each of those devices was equipped with a harvester that converted the radio waves from the router
whether it contained actual data or the aforementioned power traffic into direct current voltage, which was boosted then to a usable voltage with a DC-DC converter.
In their tests, they were able to operate the camera up to 17 feet away, the temperature sensor up to 20ft away and the battery chargers up to 28 feet away from their router.
Using a 2. 4ghz antenna and their harvester the researchers also built a wireless USB charger (top image.
It was able to charge a Jawbone UP 24 from 0%to 41%in 2. 5 hours while placed a couple of inches away from their router.
Finally, the researchers tested how their routers fared in real world settings. They asked six different households to use a Powifi router for their usual Internet activities for a few days.
They also installed harvester-equipped temperature sensors 10 feet away from each router. Their results showed that the routers performed well,
adjusting for client traffic both within the households and from neighboring routers while still sending enough power to the temperature sensors.
The researchers hope that their technology will lead to battery-free sensors and mobile devices that are powered continuously by Wi-fi routers.

#Electrical engineers Break Power and Distance Barriers for Fiber optic communication Electrical engineers have broken key barriers that limit the distance information can travel in fiber optic cables
This advance has the potential to increase the data transmission rates for the fiber optic cables that serve as the backbone of the internet, cable wireless and landline networks.
The new study presents a solution to a longstanding roadblock to increasing data transmission rates in optical fiber:
which in turn extends how far signals can travel in optical fiber without needing a repeater, said Nikola Alic, a research scientist from the Qualcomm Institute, the corresponding author on the Science paper and a principal of the experimental effort.
The frequency comb described in this paper ensures that the signal distortions called the rosstalkthat arises between bundled streams of information travelling long distances through the optical fiber are predictable,
In this study, we present a method for leveraging the crosstalk to remove the power barrier for optical fiber
In an optical fiber, information is transmitted through multiple communication channels that operate at different frequencies. The electrical engineers used their frequency comb to synchronize the frequency variations of the different streams of optical information
called the ptical carrierspropagating through an optical fiber. This approach compensates in advance for the crosstalk that occurs between the multiple communication channels within the same optical fiber.
The frequency comb also ensures that the crosstalk between the communication channels is reversible. fter increasing the power of the optical signals we sent by 20 fold,
when it is sent through the optical fiber. With the frequency comb the information can be unscrambled and fully restored at the receiving end of the optical fiber. e are preempting the distortion effects that will happen in the optical fiber,
