BAN technology
What is BAN
 Stands for BODY AREA NETWORKING.
 Also known as WBAN(Wireless BAN).
 A mobile network over human body.
 Data can be transfered over human body (upto 100 mbps MAX.).
 IEEE 802.15.6 is the task group for WBAN.
Components
 Sensors(mobile & intercommunicating)
 Low duty cycle
 TinyOS .
 Network Protocol.
 Peer to peer or point to multipoint connection
How it works
 Transmitter circuit Sends data in form of electric field.
 Receiver decodes the signal
Properties
 Distance 2 m std, 5 m special
 Devices per network max. 100
 Net network throughput 100 Mbit/s max.
 Power consumption ~ 1mW / Mbps (@ 1 m distance)
 Startup time < 100 μs
 Latency (end to end) 10 ms
 Network setup time < 1 sec
(after initial setup, per device)
 Remote wake up & effective sleep mode(s).
Real life Application
Health Sector
 Can inform the doctor about a patient before Heart attack
 Can inject Insulin to a Dibetic patient on decrease in insulin level
 In ICU multiple cables for patients monitoring can be replaced by small wireless networks
Advantage
 Less power consumption.
 Future proof.
>Backword Compatible,scaleable,upgradable.
 Simplified MAC address & less complex network layers.
 Omni-directional antennasmall,flexible.
 Several power management/consumption schemes.
 Devices are wearable or implanted.
