ANT is an ultra-low power (ULP) wireless protocol for sending information wirelessly from one device to another, so that your phone, bike computer, heart rate monitor, power meter and other training devices can talk to each other and allow technology to make your cycling (and life) better than ever. But how does it work?

Powermeters have long been a chore to setup, maintain, and always demanded a distinct weight penalty. Things are changing though - with the explosion of ANT+ wireless resulting in the fantastic Garmin 705, continued developments in PowerTap hub design, and the completely redesigned Zipp 404s, well, the future is now.
