Finally, some good news for LightSquared and its 4G hopes

Things might finally be looking up for LightSquared, the much ballyhooed wireless startup with big plans to blanket the U.S. with 4G LTE service.

The company, which seemed doomed a year ago after the GPS industry successfully lobbied against its efforts to use 40MHz of unused satellite spectrum for terrestrial wireless broadband, may be getting a second chance after all.

This week the company received approval from the Federal Communications Commission to test the feasibility of sharing spectrum with the federal National Oceanic and Atmospheric Administration (NOAA). If all goes well with the testing, the company could use this … Read more

LED lights could become network devices, too

Today, you've got wireless networks that use radio waves and you've got optical networks that use light traveling in tiny glass fibers. Tomorrow, if Fraunhofer Institute research comes to fruition, a combination of the two could turn living-room lights into network devices.

The German applied-research lab has developed wireless networking that uses rapidly blinking LEDs to transmit data through the air. The technology can send data at speeds up to 1 gigabit per second -- and by using three colors of light, triple that data rate is possible, Fraunhofer said.

The technology could be useful in crowded, interference-prone … Read more

Strobe Light Review

Strobe Light is exactly as it sounds: a strobe light. For that reason alone, this review will be very simple. Turn on the app and it starts to flash. Not so rapidly as to give you a headache and not so slowly as to attract the attention of a nearby emergency vehicle, but as you would expect from a strobe light for a party or concert. That alone is a nice feature; it works well on both the iPad and iPhone and it doesn't drain your battery quite as rapidly as some flashlight apps that have strobe functions.

That … Read more

More than ever, there is also an overwhelming number of LED varieties, and … Read more
