WiFi, also known as wireless internet, is a set of standards that allows the construction and operation of wireless networks. Over the years, it has become an integral part of our daily lives. We can enjoy the convenience of WiFi at home, at work, and even in public places. But how exactly does WiFi work?
Every WiFi network operates based on two fundamental principles – the transmitter and the receiver. The transmitter (also known as a router) is a device that sends WiFi signals through space. During this process, the signal is divided into small data packets, which are then transmitted to the receivers (laptops, smartphones, etc.) within the network’s range.
The receiver receives these data packets and reproduces them as usable information that we can see on our devices. To maintain a stable and fast WiFi connection, the router uses different radio frequencies that require a special range of licenses.
The basic WiFi standards are 802.11a, 802.11b, 802.11g, 802.11n, and the latest 802.11ac. Each standard differs in throughput, range, and data transmission speed. Therefore, older devices may have weaker and slower WiFi connections compared to modern gadgets.
Is frequent use of WiFi harmful to our health? According to many studies, WiFi radiation is low enough that it does not have a negative impact on humans. However, it is always recommended to maintain a certain distance from the router to minimize exposure to electromagnetic radiation.
WiFi has both its advantages and disadvantages. It is convenient and allows us to access the internet without cables, but it can also be susceptible to interference or lower speeds due to various factors.
FAQ:
1. What is WiFi?
WiFi is a set of standards that enables the creation of wireless networks.
2. How does WiFi work?
WiFi works by transmitting signals through a transmitter (router) and receiving them through receivers (devices within the network’s range).
3. What are the differences between WiFi standards?
Differences between WiFi standards include throughput, range, and data transmission speed.
