The idea of wireless refers to wireless connectivity.
Wireless is a word in the English language that can be translated as "wireless" or "wireless" . Its use, therefore, could be linked to any type of communication that does not require a physical propagation medium. However, the notion of wireless is mainly used to name wireless communications within the framework of computer technologies.
In wireless communication, therefore, the sender and receiver are not linked by cables, but instead rely on the modulation of electromagnetic waves through space to send and receive data .
Wireless connectivity
Computers and mobile phones are some of the devices that can use wireless connectivity. For this they must be equipped with cards or antennas prepared for this purpose.
For those devices that do not have said antenna, there are in many cases external adapters that are easy to install and, generally, at very affordable prices. In the case of computers, both laptops and desktops, that do not come prepared to connect via wireless networks, adapters are usually used that connect to a USB port and that search for the closest access points or devices ( according to the technology you want to use, which can be WiFi or Bluetooth, among others).
WiFi access
Radio frequency waves help communicate when one of the actors does not have a fixed location. A person with a laptop, for example, can travel around the world and maintain communication thanks to the wireless connectivity of systems such as WiFi .
This is especially useful for people who travel frequently, as all international airports offer WiFi hotspots to their customers free of charge, giving them the opportunity to make last-minute travel queries, book a hotel room or Simply say goodbye to your loved ones through a chat session.
Wireless technologies facilitate communications.
Problems of wireless technologies
Currently, however, wired networks still have advantages over wireless ones, especially in terms of the speeds they support. This means that in a network that operates through cables, data is transmitted faster than in a wireless network.
Another problem that wireless networks can face is signal loss , when radio waves do not reach the sending or receiving equipment due to interference or various environmental factors. It is known that wireless networks are susceptible to electromagnetic radiation from certain devices, very common in homes and offices, which is why a WiFi connection does not usually provide its users with the same speed as when using the same service through a wireless connection. wire.
The limitations of batteries
In the case of computer peripherals and video game consoles , several wireless alternatives to traditional keyboards, mice and controllers emerged in the 90s, but they always had to face the limitations of batteries: their size is directly proportional to their capacity. (which inevitably affects the weight they add to the product they feed) and the production cost is very high.
As the years go by, batteries become increasingly cheaper, but the demands on the devices become greater. For example, the latest generation mobile phones, capable of taking photos and videos, connecting to the Internet , playing music and movies, running video games and all types of applications, do not usually have a battery life much greater than 24 hours, time which decreases considerably the more calls are made.
In any case, the conveniences offered by wireless technology are many and very tempting, especially because they give more flexibility when it comes to arranging the devices in a room and protect them from falls due to entanglement with cables.
