I received a nice surprise today when I heard "Tech News Today" read and discuss an email I sent in about my thoughts on Google's Project Ara. (Time segment 31:58 to 35:37)
I've been asked a couple of times what are they referring to in the video when they talk about "white space". It's the bands of frequencies between radio station, cellphone channels, wi-fi bands, etc. left unused by older, less capable equipment that today can now be precisely targeted. Think about a white sheet of paper. A child's writing is large and the white space between lines of text
are equally large. An adult is capable of writing smaller text with small while space between lines. Indeed, an adult could write a line or two in the white space of a child's writing. Similarly, a computer printer is capable of writing many many lines of text in the white space between an average adult's writing. White space can also refer to the unwritten portion of the paper left at the bottom as well as the margins around the edge. "White space" is simple frequencies unused
yesterday but targetable today.
