Inflight Wi-Fi Interfering with Flight Critical Electronics

 

Inflight Wi-Fi and cellphone services, which transmit low power microwave radio signals within an aircraft's fuselage, has been found to be interfering withflight critical electronics. This latest finding was made by Boeing while testing inflight Wi-Fi equipment for use on its next generation 737 twin-engined aircraft. The plane maker found that a certain type of new, brighter … [Read more...]

Energy Usage Data Standard for U.S. Smart Grid

 

The governing board of the public-private Smart Grid Interoperability Panel (SGIP) has voted in favor of a new standard important for two-way data communications between utilities and their customers, bringing the next-generation "smart" electrical power grid a step closer to reality. The data standard was developed by the North American Energy Standards Board (NAESB) at the … [Read more...]

Bandwidth Battle Brews between Cell Phones, GPS
