Laptop revolution: New class design saves schools money, space

  • PDF
TechAndComputer (Mar. 9, 2010) — Universities around the country are struggling with shrinking budgets, even as they need to cater to the needs of an increasing number of students. New research from North Carolina State University shows that one way to cut down on costs, and simultaneously improve the learning experience, is to have students use the technology they already bring into the classroom.

Specifically, the NC State researchers launched...

Call forwarding: New procedure could speed cell phone testing

  • PDF
TechAndComputer (Apr. 4, 2010) — By accurately re-creating the jumbled wireless signal environment of a city business district in a special indoor test facility, researchers at the National Institute of Standards and Technology (NIST) have shown how the wireless industry could lop hours off the process of testing the capabilities of new cellular phones. The NIST techniques also could simulate complex real-world environments for design and test...

Battery-less radios developed

  • PDF
TechAndComputer (Feb. 10, 2010) — At the International Solid State Circuit Conference, imec and Holst Centre report a 2.4GHz/915MHz wake-up receiver which consumes only 51µW power. This record low power achievement opens the door to battery-less or energy-harvesting based radios for a wide range of applications including long-range RFID and wireless sensor nodes for logistics, smart buildings, healthcare etc.

Wireless optical transmission key to secure, safe and rapid indoor communications

  • PDF
TechAndComputer (Jan. 28, 2010) — Light is better than radio waves when it comes to some wireless communications, according to Penn State engineers. Optical communications systems could provide faster, more secure communications with wider bandwidth and would be suitable for restricted areas like hospitals, aircraft and factories.

Sending information via light waves either in physical light guides or wirelessly is not new, but existing wireless...
