Free-Space Optical (FSO) Satellite Networks Performance Analysis: Transmission Power, Latency, and Outage Probability
For the Toronto--Sydney inter-continental connection in an FSOSN with Starlink's Phase 1 Version 3 constellation, when the LISL range is approximately 2, 900 km, the mean network latency and mean average satellite transmission power intersect are approximately 135 ms and 380 mW, respectively.
Temporary Laser Inter-Satellite Links in Free-Space Optical Satellite Networks
In comparison with the NG-FSOSN, the improvement in latency with the NNG-FSOSN is significant at LISL ranges of 1, 500 km, 1, 700 km, and 2, 500 km, where the improvement is 16. 83 ms, 23. 43 ms, and 18. 20 ms, respectively, for the Sydney-Sao Paulo inter-continental connection.
On Crossover Distance for Optical Wireless Satellite Networks and Optical Fiber Terrestrial Networks
It is observed from the numerical results that the crossover distance increases with an increase in the number of hops, and this increase is higher at higher satellite altitudes in OWSNs and lower refractive indexes in OFTNs.
Link Budget Analysis for Free-Space Optical Satellite Networks
The satellites in these FSOSNs will have limited energy and thereby limited power, and we investigate the effect of link distance and link margin on optical inter-satellite link transmission power, and the effect of slant distance, elevation angle, and link margin on optical uplink/downlink transmission power.
The Digital Divide in Canada and the Role of LEO Satellites in Bridging the Gap
In 2016, the Canadian Radio-television and Telecommunications Commission announced broadband Internet as a basic service available for all Canadians.
When to Crossover from Earth to Space for Lower Latency Data Communications?
Numerical results reveal that a higher refractive index of optical fiber (or $i$) in an OFTN and a lower altitude of satellites (or $h$) in an OWSN result in a shorter crossover distance.
Optical Wireless Satellite Networks versus Optical Fiber Terrestrial Networks: The Latency Perspective
Formed by using laser inter-satellite links (LISLs) among satellites in upcoming low Earth orbit and very low Earth orbit satellite constellations, optical wireless satellite networks (OWSNs), also known as free-space optical satellite networks, can provide a better alternative to existing optical fiber terrestrial networks (OFTNs) for long-distance inter-continental data communications.
Laser Inter-Satellite Links in a Starlink Constellation
Then, using satellite constellation for Phase I of Starlink, we study the effect of varying a satellite's LISL range on the number of different types of LISLs it can establish with other satellites.
A Fast Heuristic for Gateway Location in Wireless Backhaul of 5G Ultra-Dense Networks
Each small cell is associated with one gateway and all small cells forward their traffic to their respective gateway through multi-hop mesh networks.
Free Space Optics for Next-Generation Satellite Networks
In addition, the optical wireless satellite network that is created by utilizing laser ISLs is examined.
