Description: A wireless network is a type of network that uses radio waves to connect devices without the need for physical cables. This type of network allows communication between devices such as computers, mobile phones, printers, and other equipment, facilitating mobility and flexibility in accessing information. Wireless networks are fundamental today, as they enable Internet connectivity and communication in environments where wiring would be impractical or costly. The main characteristics of wireless networks include their ability to support multiple devices simultaneously, ease of installation, and adaptability to different environments. Additionally, wireless networks can be of different types, such as Wi-Fi, Bluetooth, and cellular networks, each with its own specifications and uses. The relevance of wireless networks lies in their role in digital transformation, enabling connectivity in homes, offices, and public spaces, and facilitating the development of emerging technologies such as the Internet of Things (IoT) and robotics.
History: Wireless networks have their roots in the invention of radio in the late 19th century. However, the development of modern wireless networks began in the 1970s with the creation of ALOHAnet technology at the University of Hawaii, which allowed communication between several islands. In 1997, the IEEE 802.11 standard was established, giving rise to Wi-Fi, revolutionizing the way people connect to the Internet. Since then, technology has rapidly evolved, with improvements in speed, security, and connection capacity.
Uses: Wireless networks are used in a wide variety of applications, from Internet access in homes and offices to connectivity in mobile devices and smart home systems. They are also essential in industrial environments, where they enable communication between machines and control systems. Additionally, wireless networks are fundamental for the development of emerging technologies such as the Internet of Things (IoT), where numerous devices connect and communicate with each other.
Examples: A practical example of a wireless network is Wi-Fi, which is used in most homes and offices to provide Internet access. Another example is the use of Bluetooth to connect devices such as headphones and speakers to mobile phones. In the industrial sector, wireless sensor networks are used to monitor environmental and machinery conditions in real-time.
