The concept is similar to a wooden tongue drum. When a tongue is quickly and lightly struck with the finger or mallet, it vibrates creating sound waves. Playing a HAPI is similar to playing the Hang Drum, though the similarities end there, as it is a totally different type of musical instrument. By changing the shape and length of the tongue, optimal vibration and perfect tone is achieved. By arranging the notes in a unique way each note, when struck, excites surrounding notes that are musically compatible with it. This adds to the harmonic spectrum of the tone. Rather than just one tone it can now create a spectrum of supporting sound for each note. The tone is similar to singing bowls or musical bells which create multiple harmonic overtones. The body of the drum acts as a resonating chamber adding depth to the note. An opening port in the bottom of the drum serves three functions. The bottom hole allows the sound to escape and increases the volume. It releases the tone from the body so that the notes do not overlap each other too much. http://www.makeahistory.com/index.php/album-rewievs/42959-hapi-drum-The concept is similar to a wooden tongue drum.

Utilising unused radio waves could help to boost broadband speeds in rural areas and could enhance wireless connectivity between a variety of devices.

Want more wireless broadband? Sure, we all do, even the FCC, which is making a case to open up more disused portions of the spectrum. The first goal is to come up with a way to sate Congress's demands for a nation-wide broadband service, as opening up the airwaves would certainly be a lot cheaper than running more wires everywhere.
Secondly, though, the FCC wants to assuage issues cellular providers are having in keeping bits flowing to all those fancy new smartphones. Exactly how long it'll take for the FCC to rope off another few bands of frequencies for use remains to be seen, but we're sure whenever it does it'll use them as another reason to block white space approval.

No surprises here, but boy is that going to be a difficult expense to justify on the ol' corporate card. AT&T says it'll pay a $1.3 billion down payment to the FCC within the next 10 days to get a lock on that spectrum it just won, $500 million of which was paid up front before the auction began. The company will be pushing the remaining $5.3 billion over the counter before April 17, and is financing the purchase with funds from operations and a good bit of debt. We haven't seen a similar filing from Verizon yet, but we're guessing the company is facing similar deadlines for its $9.36 billion of spectrum.No surprises here, but boy is that going to be a difficult expense to justify on the... more

The 700MHz auction represents the last large chunk of spectrum available for the FCC to auction in the foreseeable future. In addition, the spectrum, now used to carry over-the-air television signals, can be used to carry long-range wireless broadband traffic.
Some consumer groups have called the auctions the "last, best hope" for a third pipe that competes with cable operators such as Comcast and DSL and fiber-based providers such as AT&T and Verizon Communications.The 700MHz auction represents the last large chunk of spectrum available for the FCC... more

"If you can't beat 'em, join 'em," appears to be Verizon Wireless' new motto as it today announced an impressive "open access" plan for its network that will go into effect next year. Any application can run on any device from any developer and will have full access to Verizon spectrum, so long as it can properly connect to the network."If you can't beat 'em, join 'em," appears to be Verizon... more
