Abstract / Description of output
for its significant benefits in energy efficiency
and capacity of heterogeneous cellular networks. However, a
large scale outdoor installation of SCs is limited by cost factors.
Therefore, wireless backhaul communication and wireless power
supply to SCs could significantly reduce deployment costs. The
focus of this paper is on the investigation of the use of free
space optical (FSO) links for power transfer to SCs in an indoor
environment. In particular, an experimental design of a red
light link for wireless power transmission (WPT) and energy
harvesting (EH) is presented in the absence of ambient light.
The transmitter includes up to five laser diodes (LDs) with a
typical output optical power of 50mW per LD. Light collimation
is achieved by the use of aspheric lenses. The receiver comprises
a crystalline silicon (c-Si) solar panel placed at 5.2m from the
optical transmitter. The use of five pairs of LDs and lenses
results in a maximum harvested power of 10.4mW. This study
shows that the number of optical transmitters required for the
generation of an electrical power of 1W (demanded for the
operation of a SC) from the solar panel is estimated to be 110.
