During a ‘fireside chat’ at the UBS Global Media & Communications Conference, Comcast (NSDQ: CMCSA) CFO Michael Angelakis explained his company’s decision not to participate in the upcoming 700 MHz auction, which it announced earlier this week. While the company is interested in wireless technology in theory, it’s not interested in doing a me-too voice product, which is along the lines of what Time Warner (NYSE: TWX) Cable CEO Glenn Britt said on Monday. In the meantime, Comcast does already own spectrum and it’s still figuring out the best use of it. Angelakis also expressed unease at the thought of making a big wireless investment at a time when there’s so much disruption from such developments as open access and Google’s (NSDQ: GOOG) interest in the space.
