“…A million-dollar question arises that when wireless network is so much popular then why satellite internet is not being developed on a fast pace. This paper discusses this topic in details be reviewing historical development as well as failures in the field of satellite communication (3). Mainly satellite communication cost depends on four major parameters.…”

The internet is the backbone of today’s digital world. A cobweb of fiber optics/wireless towers have been spread all over the globe for internet access in every nook and corner of the globe. Though fiber optics is a very costly affair, major industries are still opting for fiber network instead of satellite communication. Satellites can be placed in three different orbits for connectivity. These are LEO, MEO, and GEO. Despite so much advancement in the space technologies, satellite broadband is still in its infancy stage. This paper reviews why fiber optics have been the choice of technology giants instead of satellite communications. This paper also discusses various difficulties in implementation of satellite broadband and the implementation of the Starlink project for satellite broadband. This paper also sheds light on how the SPT (Squeeze Pack and Transfer) compression algorithm helps in improving internet implementation using satellite communication.

“…A variety of alternative policy and technology solutions have been proposed [16]. One of the options which has received the most media attention is LEO satellite constellations to deliver high-capacity wireless broadband connectivity and support the deployment of the Internet of Things (IoT) [17]- [19]. The aim is to increase the available data rate, achieving higher Quality of Service (QoS), thus helping to lower the cost per bit for serving the hardest-to-reach areas.…”

Delivering broadband connectivity to unconnected areas is extremely challenging. The emergence of Low Earth Orbit (LEO) satellite systems has been seen as a potential solution for connecting remote areas where engineering terrestrial infrastructure is prohibitively expensive to deploy. Despite the hype around these new technologies, we still lack an open-source modeling framework for assessing the techno-economics of satellite broadband connectivity which is therefore the purpose of this paper. Firstly, a generalizable techno-economic model is presented to assess the engineering-economics of satellite constellations. Secondly, the approach is applied to assess the three main competing LEO constellations which include Starlink, OneWeb and Kuiper. This involves simulating the impact on coverage, capacity and cost as both the number of satellites and quantity of subscribers increases. Finally, a global assessment is undertaken visualizing the potential capacity and cost per user via different subscriber scenarios. The results demonstrate how limited the capacity will be once resources are spread across users in each satellite coverage area. For example, if there is 1 user per 10 km 2 we estimate a mean per user capacity of 24.94 Mbps, 1.01 Mbps and 10.30 Mbps for Starlink, OneWeb and Kuiper respectively in the busiest hour of the day. But if the subscriber density increases to 1 user per km 2 , then the mean per user capacity drops significantly to 2.49 Mbps, 0.10 Mbps and 1.02 Mbps for Starlink, OneWeb and Kuiper respectively. LEO broadband will be an essential part of the connectivity toolkit, but the results reveal that these megaconstellations will most likely have to operate below 0.1 users per km 2 to provide a service that outcompetes other broadband connectivity options. The open-source codebase which the paper contributes is provided with the hope that other engineers will access, use, and further develop the satellite assessment capability.
