Find out how Satellite Internet contributes to global internet coverage.
The advancement of global connectivity has become a reality in the contemporary world and satellite internet appears as one of the main channels responsible for its rapid expansion and accessibility.
Given the constant development of communication technologies, satellite Internet represents a great example of an efficient solution for connecting people and communities in remote areas, where traditional Internet access is challenging.
Therefore, it is important to understand how this technology works, its applications in essential sectors, the challenges it faces and the solutions that could shape the future of internet access in the world.
How does Satellite Internet work?
Instead of relying on cables or terrestrial towers, satellite internet provides internet access to users through a satellite dish equipped with a transmitting and receiving unit to connect to geostationary satellites in orbit.
In short, the internet signal is sent by the provider to a large antenna on the ground (called a “ground station”), which transmits the signal via radio waves to the satellite, reflecting the signal to a satellite dish in the customer's home. .
From there, the signal goes through a cable that connects to the modem – just like with any other internet service provider.
Practical Applications of Satellite Connection
Satellite Internet plays a very important role in various practical sectors involving remote areas. Among them we can mention:
Remote Education
The transmission of online classes makes education possible in distant regions, allowing students to access quality educational content, regardless of their geographic location.
To exemplify the importance of this application, we can mention an initiative promoted by iFood in partnership with Starlink, which launched a project to enable the internet access for schools in rural areas in the states of São Paulo and Santa Catarina. Around 10 public schools in the cities of Cunha (SP) and Lages (SC) benefited, only in the pilot phase of the project.
Telemedicine
In remote areas, telemedicine is the method by which people access essential healthcare services. Through this practice, patients can receive diagnoses and medical treatments remotely, increasing the quality of life in difficult-to-access places.
A recent survey carried out by the Regional Center for Studies for the Development of the Information Society (Cetic), shows that 33% of doctors and 26% of nurses across the country carried out teleconsultation when caring for patients in 2022, a number that tends to grow with over the years and that is why it is necessary to maintain accessible internet connections for these people.
Connected Agriculture
Modern agriculture needs constantly updated and accurate information, it is in this context that satellite Internet reaches its protagonism, providing real-time data on climate conditions, soil and crops, optimizing the use of inputs and increasing production efficiency.
Business development
Remote businesses can operate effectively thanks to satellite connectivity, something that opens up opportunities for business ventures in regions previously challenged due to a lack of communications infrastructure.
The Importance of Satellite Internet Regulation
Regulation plays an important role in ensuring that satellite communications occur in a reliable, secure and interoperable manner, the focus is mainly on the allocation of frequency spectrum and the standardization of communication protocols.
In order for internet provider companies to work in the national market, they must follow rules and regulations imposed by ANATEL, complying with the minimum general and specific technical requirements for transmission antenna, resource management and quality of the multimedia communication service to avoid problems of signal interference or negative impact on the environment.
What are the Main Challenges faced by Satellite connection?
Although satellite Internet offers numerous advantages, such as connectivity in remote areas, it also faces significant challenges that need to be addressed to ensure its continued success in mitigating the digital divide.
Among the main challenges faced by the satellite Internet market, we can mention:
- Cost and Accessibility: The implementation and maintenance of satellite infrastructure is expensive, which can result in high costs for end users, therefore, to be able to combat the digital divide, it is necessary to ensure that satellite Internet services are accessible to communities in remote areas and with limited resources.
- Latency: High latency is a very common challenge, especially when it comes to applications that require real-time responses, such as online games and video conferencing. The orbit of geostationary satellites, approximately 35,786 km from Earth, is one of the main factors for the high response time for online commands using the satellite signal.
- Competition and production of space debris: With several companies launching constellations of satellites, there is growing concern about the risk of collisions between them, something that generates a large amount of space debris and poses a threat to the safety of space.
New satellite internet solutions towards global connectivity.
As satellite internet technology develops, innovative solutions are emerging to address the aforementioned challenges and boost global connectivity. Check out some of the featured solutions that are shaping the future of satellite Internet:
Low Orbit Satellite Constellations:
To overcome the latency challenge, companies like SpaceX and OneWeb are launching constellations of satellites into low-Earth orbit closer to the planet, which offer broader coverage and significantly reduce latency, making satellite Internet advantageous for users as well. applications that require instant responses.
Cost Reduction and Accessibility:
Some government initiatives are also contributing to making satellite Internet services more accessible. A great example is seen in the approval of Provisional Measure 1018/20 in the first half of 2021 by the Chamber of Deputies, which resulted in the Law 14,173/21.
Its objective, above all, is to reduce charges for satellite internet earth stations and introduce changes in the rules for applying resources from the Telecommunications Services Universalization Fund (Fust) and the expectation is to increase the number of transmission stations in the country from 350 thousand to 750 thousand.
Smaller Satellite Technology and sustainable approach:
The development of smaller, more cost-effective satellites, coupled with growing sustainable practices in the space industry, are facilitating the deployment of constellations optimized for affordable and efficient delivery of satellite Internet services.
As it becomes more popular, companies are exploring innovative satellite designs that maximize efficiency, reduce costs and minimize environmental impact.
Conclusion
As humanity moves towards an increasingly digital and interconnected future, satellite Internet is proving to be a fundamental technology in overcoming the challenges of digital exclusion and expanding the frontiers of connectivity.
This transmission technique is transforming lives and driving development in the most diverse areas, whether facilitating education in remote areas, enabling telemedicine or boosting precision agriculture.
The search for innovative solutions, such as satellite constellations in low orbit and innovative design, is paving the way for a more promising future where current obstacles, related to high costs and high latency, will be overcome.
With proper regulation and continued efforts to make satellite Internet accessible to all, we are on a path that promises truly global and inclusive connectivity.
