Devolo Boosts Wifi With Repeater ac

  • PDF

Devolo Wifi repeaterCustomers wanting a simple means to extend the range of home wifi can find an ideal solution with the Devolo Wifi Repeater ac, a device the company says provides transfer rates reaching up to 1200Mbit/s.

The repeater uses both 2.4 and 5GHz wireless networking bands to allow for more flexibility in automatic channel selection, as well as faster combined networking speeds. It also includes an integrated LAN port for the wired connection of another device, such as a smart TV, PC, game console, STB or NAS drive.

Domotz Acquires Fing

  • PDF

The Domotz home intelligence product and remote tech support offering sets to get further capabilities as the company acquires Fing, the network scanning mobile device app described as one of the most popular in the world.

Domotz appsLaunched back in 2011, the Fing app allows users to quickly scan a network and see all connected devices, evaluate security levels, detect intruders and resolve network issues through a smartphone. The app boasts 12 million downloads and 6 million active users performing over 600000 network scans daily, discovering billions of connected devices every year around the world.

“At Fing, we have always believed in building networking apps that are seamless to use and productive for our users,” the developers say. “We are very excited to continue our work together with Domotz on new products and innovations that are even more relevant and loved by our user base.”

A Passive Means to Reduce Wifi Energy Use

  • PDF

University of Washington researchers reveal a means to reduce the power consumption involved with wifi networks-- "Passive Wifi" using virtually no energy even when providing data transfer speeds of up to 11Mbps.

Passive WifiFor the curious Passive Wifi energy consumption reaches up to 49.28 µW when pushing 11Mbps transmissions. Energy use is even lower during 1Mbps transmissions, being around 14.48µW. According to the researchers such a rate is 1000x lower than Bluetooth LE and ZigBee, or 10000x lower than existing wifi chipsets.

To achieve such power reductions Passive Wifi involves a redesign of the power-hungry radios making a router, creating a single device users plug into walls. The plug-in device generates a continuous wifi signal which in turn is reflected by passive devices, creating a chain of low-power transmitters.

Samsung Proposes "Space Internet"

  • PDF

Samsung proposes a means to provide the world with an additional zetabyte of data transfer capacity every month-- a "Space Internet" system consisting of 4600 tiny Low Earth Orbit (LEO) satellites.

Space InternetIn a paper titled "Mobile Internet from the Heavens," Samsung R&D president Farooq Khan forecasts global demand for mobile demand will reach 1 zettabyte per month by 2028, and as such companies need to gear up now if they want to provide the bandwidth required.

Enter the Space Internet. The system consists of a network of so-called micro satellites (weighting less than 500kg) at 1500-2000km altitude. Such satellites cost relatively less to manufacture and deploy, and can essentially blanket the world with faster mobile internet (providing 200GB/month for 5 billion users worldwide) following the widespread adoption of 5G technology.

NASA's Low-Power Wifi "Reflector"

  • PDF

Researchers at the NASA Jet Propulsion Laboratory (JPL) design a wifi chip to bring great power savings to connected mobile devices through the use of reflections instead of the regular transmitter/receiver component.

Wifi reflection"The idea is if the wearable device only needs to reflect the wifi signal from a router or cell tower, instead of generate it, the power consumption can go way down (and the battery life can go way up)," researcher Adrian Tang says.

In a few words, the concept uses a simple switch mechanism where incoming energy absorbed the circuit is "0" and reflected energy is "1." Such a system uses very little power and allows for fast data transfer between a wearable device and any other device capable of receiving data.
