Google and TV White Space for WiFi

It's interesting to see Google out here continuing to make a ruckus, the latest being an attempt to harness the 'white space' spectrum between TV channels for WiFi signals. Fascinating concept, but can it work? Those white spaces were originally intended to be guard bands to prevent bleeding between signals. Skeptics say that white space can't be harnessed without causing interference or fragmenting the spectrum to a great degree. Meanwhile, Google says you can aggregate those signals easily enough without causing interference and get a really great medium for WiFi. Plus it should be an easier task with the onset of digital TV.

What do you think, can TV white space be utilized for WiFi without interfering with broadcast TV?

In time the current TV channels allocations will be phased out for HDTV, this leaves a large spectrum available for communications, there's also possibility of using another carrier sub frequency on existing transmission, it's interesting for sure.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
