Super WiFi Hits the Streets
In September of 2010, the FCC allowed part of the spectrum previously used for television transmissions (now made available with TV's move from analog to digital) to be used for super WiFi.
Eric Berger at The Houston Chronicle explains why this is good news for WiFi users:
"The newer chunk of the spectrum allowed WiFi signals at longer wavelengths, which are much better at penetrating natural and man-made barriers."
The Houston grandmother is an early adopter because of the efforts of Technology For All, a Houston nonprofit that provides free wireless Internet access to low-income households in partnership with Rice University.
