WBAN PHY Layer-IEEE 802.15.6 Physical layer basics


This tutorial section on Wireless Body Area Network(WBAN) basics covers following sub topics:
Basics bands modulations frame  WBAN MAC Layer  WBAN PHY Layer  WBAN Security Layer 


This page on WBAN PHY layer describes IEEE 802.15.6 Physical Layer (PHY) basics.It explains three WBAN PHY layers viz. NB,HBC and UWB.

The PHYSICAL LAYER performs following tasks in WBAN(Wireless Body Area Network).
• Activation and deactivation of the radio transceiver
• Clear channel assessment (CCA) within the current channel
• Data transmission and reception
• Incorporate forward error correction and modulation of the data to be transmitted

Based on different frequency bands WBAN supports different physical layer versions. These includes NB(NarrowBand), UWB(Ultra Wideband) and HBC(Human Body Communication). The rate dependent parameters are configured based on various freqhency bands mentioned below:
• 402 MHz to 405 MHz
• 420 MHz to 450 MHz
• 863 MHz to 870 MHz
• 902 MHz to 928 MHz
• 950 MHz to 958 MHz
• 2360 MHz to 2400 MHz
• 2400 MHz to 2483.5 MHz
