Hi,
I also want to discuss various challenges, its features and benefits of Optical Wireless Communication:
Challenges
Simple optical frontends, off-the-shelf components and standard interfaces
Robust communication without transceiver alignment, i.e. no pointing and tracking
Optimization of optical senders and receivers for high bandwidth, high linearity and high signal-to-noise ratios
Spectrally efficient modulation for high data throughput
Support of multi-user communication
Features and Benefits
No electromagnetic interference (EMI) with radio systems
Unregulated spectrum (optical frequencies) with worldwide availability
Simple shielding by opaque surfaces (improved privacy)
Thanks,
