response to 802.15 WNG call for
presentations. Abstract In the future, most of
users want to maintain their environment mobility
within a moving personal space. So, Personal
Environment Service(PES) based on WPAN technology
would be leading killer application of
Ubiquitous services in the future. We can figure
out 5G mobile communication is only the
connections of the PES spaces.

How to increase mobile channel capacity ?
Paradigm Shift Personal Mobile Space WPAN

• Find new frequencies not developed yet ? no
  more available

• Find new signal processing techniques ? only
  few times increasable

• The only way to achieve few thousand times
  capacity reduce cell size

Key RF Parameters
March 2009

• Fixed Devices
• 1W Tx power / 4W EIRP (max)
• VHF UHF TV channels 2, 5-36, 38-51 nationwide
  (282 MHz)
• If on adjacent channel - power limit is 40mW
• Must sense signals to -114 dBm
• Personal / Portable Devices
• 100mW EIRP
• UHF TV channels 21-36, 38-51 nationwide (180 MHz)
• Must sense signals to -114 dBm
• 50mW EIRP if device uses spectrum sensing only
• Strict Out-of-Band Emissions
• In the adjacent channel must be 55dB below the
  highest average power in the channel in which
  the device is operating
• More stringent at edges of channels 36 and 38
• Devices must include adaptive power control
• Fixed devices shall transmit identifying
  information
• Device ID and co-ordinates

Conclusions

• What is the PES ?
• Facilities surrounding users can be automatically
  configured to user preference.
• The user interface environment within user space
  follows when a person moves.
• It provides broadcast, multicast, communication
  sensor convergence service.
• User terminal can select a service among services
  broadcast by providers.
• It could be leading killer application of
  Ubiquitous services.

• What are the PES Requirements ?
• Service convergence with single solution
  Especially broadcasting is necessary.
• 3-D frequency planning to avoid mutual
  interference in dense environment.
• Soft handover between AP only by protocol without
  additional device.
• WBAN requirements(802.15.06) would be a subset of
  PES requirements.

• What kind of WPAN solution is suitable for PES ?
  
• Dual support for both low power sensor and high
  speed multimedia.
• Container concept to reject mutual interference
  and converge various services.
• Abundant channel capacity based on avoidance of
  mutual interference.
• Hierarchical sync frame structure for scalable
  self organizing system.

• PES Protocol can be used for 5G mobile
  communication, too.
• PES personal space mobile femto-cell have
  almost the same structure.
• In the future, the cell size of 5G will become
  pico-cell because of capacity.
• 5G network merely a connection of user oriented
  mobile spaces (PES).
• White space devise requirements would be
  satisfied with PES protocol.
