How does Wi-Fi work?
Wi-Fi operates on the principle of radio wave transmission, allowing devices to connect wirelessly to a local area network (LAN). A Wi-Fi router serves as the central hub that transmits data to and from connected devices using radio frequency (RF) signals. When a device, like a smartphone or laptop, connects to a Wi-Fi network, it exchanges information such as data packets that travel back and forth between the router and the device.
Wi-Fi technology utilizes different frequency bands, typically 2.4 GHz and 5 GHz, to enable data transmission. The choice of band affects the speed, range, and interference levels. While the 2.4 GHz band offers a broader coverage area, it may experience more interference from other devices. In contrast, the 5 GHz band provides faster speeds with less interference but has a shorter range. As a result, users can choose the appropriate frequency for their specific needs to ensure optimal connectivity.
What is the difference between 4G and 5G wireless technology?
4G and 5G are both generations of mobile network technology, but they differ significantly in speed, capacity, and latency. 4G technology, which introduced mobile broadband connectivity, supports internet speeds of up to 100 Mbps for mobile users and up to 1 Gbps for stationary users. It enhanced video streaming and online gaming experiences but has limitations regarding data capacity and latency, which can lead to slower response times during high-demand usage.
In contrast, 5G technology is designed to address these limitations by offering considerably higher speeds—potentially exceeding 10 Gbps—and significantly lower latency, often below 10 milliseconds. This enhancement facilitates real-time applications, such as augmented reality (AR), virtual reality (VR), and advanced IoT applications. The increase in capacity and speed allows more devices to connect simultaneously without degrading performance, making 5G a crucial infrastructure for the future of connectivity.
