Wireless networks (Wi-Fi)
Wireless communication has become an integral part of life, allowing us to always be available and access information from anywhere in the world. Wireless technologies have changed the way we connect and communicate – they allow data to be transferred without the use of cables, leading to greater flexibility and mobility. They also provide an opportunity to quickly and inexpensively expand computer networks when technologies that require cabling/laying solutions are not economically viable. The three main types of wireless networks in common use today are Wi-Fi, Bluetooth and cellular.
Used in homes, offices, coffee shops and other public spaces, Wi-Fi is the most common form of wireless communication. With Wi-Fi, you can connect multiple devices to a wireless network and have access to high-speed internet. Wi-Fi technology uses radio waves to transmit data between devices and a modem. It is important to mention that Wi-Fi speed and range may vary depending on the network configuration and physical obstacles in the environment.
Bluetooth is a short-range wireless technology primarily used to establish communication between nearby devices. It is usually used to transfer information from one mobile phone to another, or to connect wireless headphones and other external devices. Bluetooth uses short-range radio frequency to transmit data, so its range is limited to about 10 metres.
Cellular networks – 3G, 4G and 5G – are wireless networks used to support mobile communications. These networks allow users to connect to the internet and make calls using mobile devices wherever there is cellular network coverage. Cellular networks use cell towers to provide coverage and transmit data via radio signals.
