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.
