Several common wireless network technologies play a significant role in facilitating connectivity for various devices. Wi-Fi technology, based on IEEE 802.11 standards, is widely used for local area networking. Wi-Fi operates on different frequency bands (2.4 GHz and 5 GHz) and has evolved through standards like 802.11n, 802.11ac, and 802.11ax, offering increased data transfer rates and improved performance. Bluetooth is another prevalent wireless technology, designed for short-range communication between devices. It is commonly used for connecting peripherals like headphones, keyboards, and speakers to smartphones and computers. Near Field Communication (NFC) enables contactless data transfer between devices in close proximity and is often used for mobile payments and data sharing. Zigbee and Z-Wave are wireless technologies designed for low-power, short-range communication in smart home devices like smart bulbs and sensors. Cellular networks, including 4G LTE and 5G, provide wide-area wireless connectivity for mobile devices, supporting high-speed data transfer and enabling internet access on the go. Each of these wireless technologies serves specific purposes, contributing to the diverse and interconnected landscape of modern wireless communication.
