Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15.
In the future, WBAN and 5G communication system would not be separated systems. To increase mobile channel capacity, it is inevitable to reduce cell size. If we reduce cell size to 3m radius femto-cell, then the base station becomes a body coordinator. Therefore we should consider 5G communication phenomena during considering WBAN standard.
Find new frequencies not developed yet ; no more available Find new signal processing technique's ; only few times increasable But we need few hundreds times capacity or more The only way to achieve few thousand times capacity ; reduce cell size
Body coordinator is not a sufficing concept. Synchronous frames can reject mutual interference among RF’s . So, Body coordinator should synchronize all of body device’s.
Better to rename body coordinator as “Body Master”.
1. In-body / Out-body Interference Chg. : Even though difference frequency band interfere each
other Sol. : Synchronized Frame can reject mutual interference
among PHY’s 128bit multi preamble is necessary to enhance sync.
probability 2. Single MAC to support Multi-PHY’s Chg. : Single PHY cannot meet so wide user requirements Sol. : Multi preamble is useful to support scalable data rate Synchronized Frame can support different PHY’s
without interference
3. Compromise Power & Speed Chg. : Low power sensor and High speed multimedia should
supported Sol. : Multi PHY concept can support Multi RF Block
Sensor use single RF Block, Multimedia use multi RF Block’s
4. Medical / Non-Medical Dual support
Chg. : Medica needs 10-10 BER performance with low speed
Sol. : 128bit Multi preamble provides enough Process Gain
Conclusion WBAN body master will work like a mobile femto-cell.
Increasing mobile channel capacity will reduce the cell size as small as possible Mutual interference among Body’s must be solved.
Additional WBAN conditions should be considered for future market. How to minimize the mutual interference among the crowded moving body’s ? How to minimize initial sync time & how to maintain synchronized status ? Who will be the super master and govern areal body’s ?
The WBAN standard should includes items as follows ; Interference cancelling in-body, on-body, out-body, & among-body Single MAC to support multi PHY for wide user requirements Compromise conflicting items (power & high speed; medical & nonmedical)
New suggestions are submitted for chaos WBAN standard Synchronous frame to reject interference in-, on-, out-, & among Body’s Multi preamble to enhance synchronization probability & for special purposes Multi RF & frame structure to compromise conflicting items
