  1. Free Space Optics The Bright Future of Wireless Communications .

  2. Lasers in Free Space?

  3. What is FSO? • Line of sight free space (wireless) transmission technology • Utilizes light (laser) to transfer data • Delivers high speed secure connection • Offers economical solution (low power consumption, no wide radiation)

  4. Optical fibre TX optics Laser transmitter Receiver Diode RX Optics Optical fibre Optical Transmission Fibre Optic TX Fibre Optic Transceiver RX

  5. TX optics Laser transmitter Receiver Diode RX Optics Optical Transmission Free Space TX Transmitter Free Space Optics Receiver RX

  6. Why Free Space Optics? • License-free operation • High bandwidth • High data security • No interference issues • Rapid deployment/re-deployment • Excellent price/performance (low cost per bit)

  7. Why LaserBit? • High quality product • Extreme dynamic range – very reliable operation • Modular design – easy upgrade and troubleshooting • Long-range models • Flexible support and services • Very competitive price

  8. Link Dynamic Range Power Margin (Dynamic Range) Budget Receiver sensitivity Distance

  9. Multibeam Systems • To increase power • To Compensate building swaying • To introduce redundancy

  10. Eye Safety 7 mm Human eye Optical apertures/surfaces TX optics: 1962 mm2 Footprint: 196250 mm2 Human eye: 38 mm2 NOHD Values 1.8 m – 85 m

  11. Birds, UFO’s,… Chance to block the beam < 10-12 Chance for UFO…?

  12. Competitive Analysis • Fibre • Leased Line • Radio • Microwave

  13. Alternative To Fibre • Cost of installation • Speed of installation • Flexibility
