One of the questions I asked in the recent article Heart Rate Monitor Data Integrated into OLN Broadcasts was how is heart rate monitor data transmitted beyond the receiver on rider's bikes? The standard transmitters for most heart rate monitors have a range of about 2 meters (6 feet).
That is the transmitter that sends telemetric data live from Voigt's SRM. And yes, some of the other Tour riders are doing the same thing. Voigt, Matthias Kessler (T-Mobile), Gerrit Glomser (Lampre) and Sebastian Lang (Gerolsteiner) all have been wired for live SRM data on various stages.
He goes on to say that the Polar auxiliary transmitter is smaller than those being used by SRM. Polar's transmitters relay their data for use on OLN.
