Internet via radio: what is it, how does it work, is it good?

Although not so popular today, the internet via radio may be the only option in regions further away from the capitals of Brazil. This is because, when using antennas to capture the signal, its implementation is less expensive than in other options, such as optical fiber, for example – a determining factor for small providers to adopt the technology.

If you are thinking of adopting the internet via radio, it is important to know how it works, as well as the advantages and disadvantages of this option. In addition, before making any decision, it is still necessary to analyze whether this internet is suitable for your user profile.

What is the internet via radio?

Well, it is not possible to explain what the internet is via radio without talking about how it works. In general, this technology depends on the signal emitted by towers (known as POPs) that are distributed at high points in a given region by the providers.

So that this signal is then captured and effectively transformed into a connection, it is necessary that an antenna is installed in the user’s residence or in the place where the internet will be used. This antenna must be placed at a high point, so that the connection to the transmission tower is facilitated.

The reception of the radio signal by the antenna does not, however, make the location instantly connected. After all, this signal needs to be converted and this is where the modem comes in, responsible for transforming it and transmitting it to the computer’s network card.

Advantages and disadvantages

Once explained how the internet via radio works, let’s go to its advantages and disadvantages:

The first on our list and one of the main advantages of this technology is the roof. The system of towers and antennas allows this internet to cover a great extent and, therefore, reach places farther from the centers, such as rural areas. In the city, this connection can also be useful, serving neighborhoods where the cable internet is overloaded or where the optical fiber has not yet reached.

In addition, your installation dispenses with the presence of a telephone or cable TV, since such internet works independently. This means, in other words, that you will not have to pay for services that you will not use – which consequently reduces your chances of falling into the famous, but illegal, married sales.

Finally, we highlight the reduced maintenance, in the event of a well done installation. This is an advantage over the wired option, since cases such as theft of wires or cuts in the cables generate additional maintenance costs.

Since the technology depends on electromagnetic waves, the instability it’s a problem here. So, just like satellite TV, the connection will “choke” with rain and storms, and can leave you hanging at any time. There are still other factors that can interfere with the stability of the internet, such as the equipment used, the distance between the antennas and the transmission tower, as well as possible interferences in the installation site of these same antennas.

THE velocity it is also not a strong point of the radio option. In general, residential customers have packages ranging from 1 MB to 10 MB. Although providers offer plans over 20 MB, they are often for commercial purposes – and, of course, higher prices.

Finally, the value. Before hiring a package, think very carefully about the cost-benefit. In general, the price per Mb / s is lower for wired options and even for fiber optics. In addition, in some cases, the user needs to buy equipment outside or pay for the installation. Which leads us to conclude that, although it is an “older” technology, it will not necessarily be cheaper.

Which profiles do you serve?

With all this on the table, it’s time to define the profiles that the internet via radio serves. Well, if you work with internet, you do streams or is a regular player of online games, this option is out of the question. In this case, prefer cable or fiber optic internet, which are more stable, faster and have better latency.

If its use is simpler, the internet via radio will serve you well. However, you need to be aware of the cost-effectiveness – which can plummet depending on the region where you live and the alternatives available. If, after the necessary analysis, you decide to hire a plan, you need to consider a few points before choosing the provider.

What to consider when hiring?

First, check if the company is legalized with Anatel. Second, find out about possible communication problems between the antenna and the provider’s tower in the region. The presence of trees, buildings and hills on the site can be decisive for a bad connection.

Last but not least, check with other customers to see if the internet suffers from peak hours. This data will be essential for choosing the best company and, of course, will help you to avoid future inconveniences.
