Artificial intelligence has gone from being a futuristic idea to becoming and consolidating itself as a technology of the present and, more than that, a real competitive differential for those who know how to use it with purpose. Since ChatGPT exploded in popularity in 2023, we have seen an unbridled race for AI-enabled solutions.

While many still use it only as a chatbot, what is really shaping the future are custom AI Assistants, also called AI Agents, which represent a concrete digital transformation.

Unlike a simple automatic response system, an AI Agent is able to act autonomously, adapt to different contexts, perform tasks and make decisions based on predefined rules and objectives. These agents combine models such as GPT-4, Claude or Gemini, with business logic, prompt engineering and integration with real workflows.

It sounds technical?It might be. But that is, in practice, the difference between using AI as a hobby or as a strategic tool to transform the operation of your company.

What makes an agent work is not just the technology, but the intelligence behind its training.Creating good prompts, with clear instructions, context and purpose, has become a new professional skill and a competitive differentiator.

Companies that understand this are already creating their own assistants with name, personality, specific functions and even memory. Some sell these agents as a service. Others use them to enhance their areas of marketing, HR, legal, service and more.

In short, today it is already possible to create AI Agents for almost any digital task. In this sense, some sectors are emerging: Marketing & Sales: content automation, lead nurturing, campaign management. Customer service: support in real time, with empathy and personalization. HR & Legal: analysis of contracts, documents, onboarding of employees. Education: custom tutors, quizzes, adaptive feedback. Health: patient screening, medical record organization, medical chatbots. 

Because in a short time, it will not be the companies with the largest teams that will grow the most, but those that know how to automate with intelligence. The ability to create specialized agents is becoming a strategic market skill. Whoever learns this now will be at an advantage. Whoever ignores, runs the risk of falling behind.

It is important to emphasize that since the Industrial Revolution, technologies have always impacted the labor market, replacing, yes, professionals who have ceased to update themselves. AI follows this same path: it is not a threat to those who evolve, but an invitation to transformation. Whoever seeks to qualify to work with Artificial Intelligence, mastering its use and, especially, learning to create customized solutions, will have more space, relevance and opportunities.

It is on this principle that I base my work in my company, developing personalized assistants with strategy, architecture and prompt intelligence, to help companies gain productivity, scale and competitiveness.

Our focus is on connecting technology to its real context, with solutions that make sense for the team, the job market and the moment of each organization.

And for those who work with marketing, we have excellent news, with the launch of MarketerValley, a free American AI platform focused exclusively on marketing and sales.It has already helped non-profit organizations, self-employed, students and companies of all sizes, especially small and medium, to create effective marketing campaigns. The tool is not yet available in Brazil, but will soon be launched here.

The AI Assistant revolution has already begun. Some people still do not know how to use this technology. Others use it superficially, for simple tasks and with shallow answers. There are also those who are concerned with extracting more qualified answers through well-targeted AI assistants. But the real opportunity is in those who learn to create these assistants, with personality, context and clear objectives, to provide a personalized experience and much more effective results.

The technology already exists. What is often missing is strategic vision.And that is why I write this article: to invite you to take the next step.

In recent years, Brazil has witnessed significant advances in new forms of wireless connectivity, especially in low-orbiting satellite internet and fixed wireless access (Fixed Wireless Access, or FWA). With the rapid expansion of 5G networks and the increased coverage provided by satellite constellations, the Brazilian market is now faced with a scenario in which these technologies can both compete and complement each other, depending on local conditions and the specific needs of users.

FWA 5G has been considered an alternative to take fixed broadband to places without fiber optic or cable infrastructure. Since December 2, 2024, all 5,570 Brazilian municipalities are able to receive standalone 5G technology, thanks to the release of the 3.5 GHz band by Anatel, anticipating in 14 months the schedule planned. Until March 2025, 5G was already present in more than 895 municipalities, especially the states of Sao Paulo (166), Santa Parana (122), Catarina 17), (16), Rio Grande (13).

In addition to the national telecoms, which have invested heavily in expansion, new regional entrants who acquired 5G licenses in the spectrum auction also bet on FWA. But despite the growing interest, the current reach is still modest compared to traditional broadband. Studies indicate that about 40% of operators with 5G globally already offer FWA challenges such as the cost of equipment and data franchises limit the adoption of FWA in mass. Because of this, the current FWA offers come with relatively restricted data franchises, and demand that the manufacturers reduce the cost of CPEs to enable further expansion.

In terms of coverage, FWA can be offered quickly 5G, including some operators already advertise the service in cities such as Sao Paulo and Campinas. On the other hand, in rural or remote areas, the absence of 5G towers is a limiter. Overall, FWA will be more widely used where there is already well-established cellular coverage, capitalizing on existing 5G infrastructure to deliver wireless fixed broadband.

Low-orbiting satellites: advancing rapidly

Parallel to the FWA, Brazil is witnessing a real revolution in the satellite internet, driven by low-orbiting satellites (LEO). Unlike traditional geostationary satellites (which orbit ~36 thousand km from Earth), LEO orbit a few hundred km, enabling much lower latencies and services more comparable to terrestrial broadband.

Since 2022, a large LEO constellation has come to serve the country and has been growing exponentially in users and capacity. Currently, satellite coverage already reaches practically 100% of the Brazilian territory SO it is enough that the user has an unobstructed view of the sky to connect. This includes everything from farms in remote areas in the interior of Brazil to riverside communities in the Amazon.

Recent data confirm the rapid growth of the LEO satellite user base in Brazil. An April 2025 report highlighted that the main low-orbit satellite internet service & Starlink 345 thousand active subscribers in Brazil, which represents an increase of 2.3 times in just one year 4th largest market in the world.

This impressive number 2 achieved in about two years of commercial operation 2023 positions satellite connectivity as a weight solution, especially in locations where terrestrial networks do not arrive. For comparison, in September 2023 it was estimated that 0.8% of all broadband accesses in the country were already via satellite, a proportion that jumps to 2.8% in the North Region, with the LEO constellation accounting for 44% of these satellite accesses (about 37 thousand connections). In some states of the North, Starlinnk already holds more than half of its niche accesses.

The National Telecommunications Agency (Anatel) approved in April 2025 the expansion of the LEO satellite license, allowing the operation of 7.5 thousand additional satellites in addition to the approximately 4.4 thousand already authorized. With this, the constellation could reach almost 12 thousand satellites in orbit serving Brazil in the coming years, strengthening its capacity and coverage.

Performance & latency

Both systems can deliver broadband speeds, but the numbers depend on the available infrastructure. In measurements in Brazil, Starlink's LEO connection of 113 Mbps download and 22 Mbps upload, with performance superior to that of other satellites. On the other hand, FWA 5G, when using medium frequencies (3.5 GHz), can reach similar or higher speeds according to the proximity of the antenna and the availability of spectrum.

Regarding latency, a fixed 5G connection usually has latency in the range of 20 to 40 milliseconds, similar to a conventional mobile network suitable for real-time applications, videoconferencing etc. The constellation of low-orbit satellites recorded latencies around 50 ms in tests in Brazil, incredibly low compared to 600800 ms of geostationary satellites.

In practice, 50 ms is close enough to the fiber experience (which rotates at 520 ms) to support almost all applications without major losses. The 30 ms difference between FWA and LEO is not noticeable for most common applications, although 5G in stand-alone mode can theoretically lower latency further as the core infrastructure evolves.

Despite the similarities, in remote rural areas, or with poor infrastructure, satellite internet consolidates as a savior of the last mile. Where there are no cell towers nearby or fiber backhaul, implementing 5G may not be feasible in the short term 'The installation of a satellite antenna becomes the fastest and best performing output.

In the Brazilian agro, for example, the adoption of the LEO internet has been celebrated as a productivity factor, connecting farms that were previously offline. Even public agencies have resorted to the spatial solution to connect schools, health posts and bases in the forest. Therefore, in shadow areas of operators, the satellite has no competition 'it fills a niche of basic and advanced connectivity at the same time, leading from basic access to the internet to the possibilities of implementing IoT solutions in the field.

In contrast, in urban areas and regions with well-structured mobile networks, FWA 5G should prevail as a preferred option for fixed wireless access. This is because in cities there is high antenna density, capacity to spare, and competition between operators 5 factors that keep prices affordable and allow generous data packages. FWA can directly compete with traditional broadband in unwireable neighborhoods, offering fiber-like performance in many cases.

In conclusion, the new connectivity scenario in Brazil points to the complementary coexistence of FWA and satellite internet. This is not a frontal competition for the same market share, but to optimally meet different geographic and usage needs. Executives and decision makers should see these technologies as allies in the expansion of connectivity: the FWA taking advantage of the 5G infrastructure to deliver fast wireless broadband where it is economically viable, and the satellite covering the gaps and providing mobility and redundancy. This mosaic, if well coordinated, will ensure that digital transformation does not know physical boundaries, bringing quality internet from the center of metropolises to the sustainable and efficient confines of the country.
