What Channels Within White Space are Actually Available?

Spectrum Bridge has launched a Web site called ShowMyWhiteSpace.com that offers an easy online tool to find open TV channels available at any location in the U.S. Now there is a place to figure out what parts of "white space" are really accessible in a given location.

“We have seen tremendous excitement about the opportunity that this vast swath of free, unlicensed spectrum opened up for new and innovative services.” said Peter Stanforth CTO and cofounder of Spectrum Bridge. “We want to make it as straightforward as possible for people to ‘show my white space’, while also helping them understand how they could benefit from white space-based solutions.”

It was a common misconception that all channels left open by the TV Stations from their transistion to digital could actually be used be future white space devices -this is not the case. Because the number of broadcast TV stations varies throughout the country, the amount and frequencies of available white space channels can differ significantly at any given location.

When Spectrum Bridge put some of our spectrum mapping technology to work along with the new white space rules set forth by the FCC, we found some areas (especially metro) where even after the digital switch is complete in June there will not be any whitespace available. If white space IS available, the FCC rules are basically saying it is up to the communications industry to figure out how not to interfere with each other. When deciphered, the few rules the FCC suggested are illustrated in the pictured graphic.

The site allows wireless microphone users to pre-register their information with Spectrum Bridge, who will ensure its secure delivery to a white space database manager, once these entities have been designated by the FCC.

Since ShowMyWhiteSpace.com is actually the first site where someone can look up a specific address and find out if white space devices are an option, as well as pre-registering devices such as microphones, the response so far has been tremendous.

It's a scam to get money out of those who want to use wireless microphones! They charge $100 a year to register your wireless microphones!

What's worse, they don't try to weed out unauthorized, non-broadcast wireless microphone users, meaning college radio stations may find themselves financially shut out and forced to stop using wireless microphones they have a right to use when someone who is using them illegally forks over the money to register!

As far as I can tell they're just putting you on a list to register you later - once the FCC names who will manage wireless a mic registry and what the actual rules are. no mention of a charge... yet.

I'm staying tuned though myself - I don't want some shmoe claiming his wireless mic takes precedence over mine because he registered it first - when it's just sitting in a studio unused!

These guys are scam. Just check the background.

ShowMyWhiteSpace.com is a valid resource for information and registration. We are actively engaged with the FCC and on the cutting edge of the White Space issue. To get involved with the site itself, feel free to visit the white space forum at: http://www.showmywhitespace.com/Forum/tabid/70/Default.aspx
