What does Wizards Wireless mean?

It's an obscure Harry Potter reference. So obscure, that it appears only three times in the books (if you've found more mentions, let me know!) It's the radio station that wizards listen to- and it seemed like the perfect name for a blog created via a wireless connection. All the major, non-obscure Harry Potter references like The Leaky Cauldron are already taken, so I thought I'd try something off the beaten path.
