Personal Space
The personal space is defined as a physical and virtual space which a person regards as psychologically the person’s.
For this standard, it is defined as a physical space where devices are controlled by or for the person, and among devices in this space of an individual. °C

23. <March 2010>
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.
