Arbitron Tweaks PPM System

Arbitron Tweaks PPM System

Arbitron said its Personal People Meter has been upgraded so it can distinguish between in- and out-of-home media exposure.
The enhanced system uses radio frequency codes transmitted at low levels by the PPM household collector to determine where consumers are while listening to radio or watching broadcast and cable TV.
Arbitron also is announcing a pair of features slated for addition to the technology. A wireless Global System for Mobile modem will help measure the increasing number of homes that only have a wireless phone. Arbitron will also offer a portable recharger, allowing the PPM to store multiple days of data. According to the company, these features are important for the requirements of audience measurement in international markets.
