Enhancing Wireless Personal Area Networks Sensitivity Levels
"Explore changes in reference receiver sensitivity levels for IEEE P802.15 WPANs, aiming to optimize module size and power consumption by modifying sensitivity levels. Lower gain antennas may enable smaller modules, while reducing power consumption of amplifiers. Proposed adjustments offer potential benefits in device design and performance."

<Sep. 2016> doc.: IEEE 802.15-15-0581-01-003e Summary Modified reference receiver sensitivity levels for TG3e are presented. Relaxation of the reference receiver sensitivity has great potential for module size and power consumption. Lower gain antennas can provide small size module. Power consumption of low noise amplifier and power amplifier can be decreased. Slide 2 Kobayashi (JRC) submission
