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.

• IEEE 802.15.1– Medium rate

• IEEE 802.15.3– 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– Short range (5 meters).

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.
