In-body: a significant part of the channel is inside the body and implanted transceivers are used. This is called the in-body domain. 5. This nomenclature implies a partitioning of the PAN and BAN space into three areas. The first is where most of the channel is off the body and in the surrounding space, and where only one antenna in the communications link is on the body, which we call the off-body domain. The second is where most of the channel is on the surface of the body, and both antennas will be on the body, called the on-body domain.
The comparison between the standing and sitting body activities has shown that the location of the transmitter should be chosen wisely, as its orientation can be altered by posture change. This may adversely affect the signal strength for receivers on the back. In most cases, statistical analysis of the measured on-body radio channels regarding path loss and deviation can be fitted to known distributions. The dependency of system performance on the applied data rate has been demonstrated and it was learned that an acceptable BER can be achieved for power levels as low as –40 dBm for low data rates mainly used in health monitoring applications.
It is noted that the antenna properties will be modified due to the presence of the human body. In addition, communication nodes on the body are often in the near radiation field region; therefore, on-body radio behavior is strongly influenced by antenna types. Chapter 6 discusses various wearable textile antennas for space exploitation and military applications. Examples for mobile phones, GPS, and WLAN applications are presented together with antenna performance enhancement technique using EBGs.
