ELECTRONICS:RAYSPAN® Corp. announced the launch of a new stand-alone metamaterial balanced antenna (MTM-B™), offering an integrated solution for ultra-high-performance WiFi access points and routers. MTM-B™ is designed to meet the requirements for single band 2.4 or 5.0GHz designs, as well as dual band 2.4/5.0GHz devices, in a small form factor of 15 x 14 mm, which is 80 percent smaller than typical dipole solutions offered today.
Balanced antennas offer multiple advantages to WiFi product designers. They can be positioned in close proximity to a ground plane without impact on the antenna characteristics. Balanced antennas also offer a higher immunity to noise and, therefore, improved sensitivity and higher long-range throughput performance. The metamaterial concept used to design these antennas allows for up to 5x size reduction without performance trade-offs, as well as a strong immunity to changes in surroundings. Stronger polarization along the length of the MTM-B™ antenna is beneficial for WiFi products incorporating chipsets that take advantage of polarization in order to improve throughput and range. This results in WiFi routers and access points with better in-home coverage.
MTM-B™ can be printed directly on the PCB, retrofitted inside existing products or integrated inside new devices. As the WiFi industry migrates from 2.4GHz only devices to 2.4/5GHz functionality, the dual band capability of RAYSPAN’s MTM-B™ antennas meets the requirements of 2×2 and 3×3 dual concurrent chipsets where a high Quality Of Service (QOS) is required for applications such as high definition video transmission inside the house for entertainment or gaming.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
