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...]
U.S. Navy to Demonstrate Electromagentic Railgun at Sea
The U.S. Navy has announced plans to test a prototype electromagnetic railgun aboard a high speed vessel in 2016. The test will mark the first time an electromagnetic railgun has been demonstrated as sea. Capable of firing projectiles at seven times the speed of sound, railgun technology uses an electromagnetic force known as Lorentz force to rapidly accelerate an object … [Read more...]
