Scientists in the UK are conducting the largest study to date on the effects of cell phone usage on adolescent and teenage brain development. The study, called SCAMP (Study of Cognition, Adolescents and Mobile Phones), will follow a group of 2,500-3,000 students in the greater London area, charting changes in brain development from Grade 7 to Grade 9. SCAMP’s mission, stated … [Read more...]
IEC 61000-3-2:2014 – Electromagnetic Compatibility (EMC) – Part 3-2: Limits – Limits for Harmonic Current Emissions (Equipment Input Current ≤ 16 A Per Phase)
The International Electrotechnical Commission (IEC) has published IEC 61000-3-2:2014, "Electromagnetic Compatibility (EMC) - Part 3-2: Limits - Limits for Harmonic Current Emissions (Equipment Input Current ≤ 16 A Per Phase)." The new standard is available in the IEC’s webstore here. "IEC 61000-3-2:2014 deals with the limitation of harmonic currents injected into the public … [Read more...]
New Magnetic Material Could Boost Hard Drives, Protect Electrical Grids
Scientists at the University of California, San Diego have developed a highly sensitive magnetic material they say could drastically change computer hard drives and electrical grids. Made of thin layers of nickel and vanadium oxide, the material is extremely responsive to heat and requires only a small shift in temperature to alter its magnetic properties. "We can control the … [Read more...]
Florida Man Fined for Blocking Cell Service on the Road
A Florida man reportedly caught using a cell phone jammer during his daily commute is facing a sizable fine for illegal interference. The Federal Communications Commission announced last week it will fine Jason Humphreys of Seffner, Fla. $48,000 for use of a signal jamming device, which work by transmitting signals that overpower, block or interfere with authorized … [Read more...]

Miniature Chip Bead Ferrites for Mobile Devices
Würth Elektronik has released a new miniature chip bead ferrite in the standard 0201 chip format. According to the company, this package design increases packing density of components on circuit boards three-fold compared with the chip bead ferrite packages previously available on the market. Ideal for mobile devices, the new chip bead ferrites offer broadband interference … [Read more...]
Gigabit Wireless Research Could Open Door to Higher Data Rates
New research on gigabit wireless communications from the University of Bristol in the U.K. could have significant implications for the future of mobile devices. Two research papers presented at IEEE Wireless Communications and Networking Conference (WCNC) in Turkey last week focused on the millimeter-wave band (58-63GHz), in which the researchers believe short-rage gigabit … [Read more...]
Wi-Fi ‘Carpool Lane’ Approach Could Triple Data Speeds
Qualcomm has announced plans for a new technology it said could triple Wi-Fi speeds in homes, offices and in crowded public network areas. Currently, all devices within a certain area compete for a finite amount of bandwidth. This competition often results in slower services for all users, especially in crowded urban areas where more devices are trying to access the sme … [Read more...]
Facebook Drones and Satellites to Deliver Global Internet
Facebook Inc. is developing a plan to deliver global Internet access using satellites, drones and other technology. Known as the Facebook Connectivity Lab, the project was announced late last month by Facebook CEO and founder Mark Zuckerberg, who aims to provide affordable Internet services to “every person in the world.” Currently, more than half of the world’s population is … [Read more...]
FCC Frees Up Airwaves for Wi-Fi Use
U.S. regulators approved measures this week to free up more spectrum for Wi-Fi and wireless broadband use in a move they hope will reduce spectrum congestion and boost the development of new, faster Wi-Fi technology. In a decision made Monday, the Federal Communications Commission voted unanimously to make an additional 100 MHz of spectrum accessible to Wi-Fi technology for … [Read more...]
