     – MAC and High rate only
• IEEE 802.15.4
     – Low rate only
• IEEE 802.15.5
     – Separation of Low and High rate.
• IEEE 802.15.6

               Need for a new Standard
 • Many devices in a personal space not interoperable.
 • Desirable to have a new solution with one
   technology not by combining multiple technologies
   into a combo chip.
 • Existing standards can serve parts of the PSC, but
   no single standard optimized for all features for
   PSC.
 • Therefore, there is a need for a new standard to
   serve the PSC applications.
