Wireless Network
Ultra-Low power wireless networking around the human body.
What will this research achieve?
Reliable wireless networks which operate at extremely low power, and do not suffer excessive interference. The work on this sub-project focuses on a number of aspects of wireless base-band and MAC design.
Channel Models for Radio around the Human Body
 | We have developed a significant library of radio channel measurements. The measurements include signal strength and power delay profiles for narrowband channels in the 400, 900 and 2400MHz bands. |
Channel simulation
We have developed a Matlab simulation which may be used to imitate the wireless channel between two points on the human body, when the person is moving slowly (eg. walking). The code is available here, under the following conditions of use:
- Licensee must include a reference to NICTA and the following publication in any published work that makes use of the simulation: Smith, Zhang, Hanlen, Miniutti, Rodda, Gilbert; A simulator for the dynamic on-body propagation channel, 2009 IEEE Symposium on Antennas and Propagation
Channel measurement apparatus
 | Wearable channel sounder The device contains a programmable wireless transceiver which operates around the 2400MHz International Scientific and Medical (ISM) band. We can apply various MAC and timing synchronization algorithms, and develop star, multi-star or arbitrary network arrangements. The devices allow us to measure signal strength and network interference. |
