There are several key technologies used to develop wireless-based networks, each with their unique features and advantages. Some of the prominent technologies used in wireless networks include:
Wireless Local Area Network (WLAN): WLANs are based on the IEEE 802.11 standard, commonly known as Wi-Fi, and are widely used for wireless connectivity within a limited area, such as homes, offices, and public places like airports and cafes. WLANs use radio waves to transmit and receive data over the air, allowing devices like smartphones, laptops, and IoT devices to connect to the internet wirelessly.
Cellular Networks: Cellular networks are based on various cellular standards, such as 3G (Third Generation), 4G (Fourth Generation), and 5G (Fifth Generation). These networks are used for wide-area wireless connectivity and provide mobile voice, data, and internet services to mobile devices like smartphones, tablets, and other IoT devices. Cellular networks use a complex infrastructure of cell towers, base stations, and core networks to provide wireless coverage over large geographical areas.
Bluetooth: Bluetooth is a wireless technology standard used for short-range communication between devices, typically within a range of up to 10 meters. Bluetooth is commonly used for connecting peripherals like headsets, keyboards, and speakers to smartphones, tablets, and other devices. Bluetooth technology is also widely used in IoT devices for communication and data transfer between devices in close proximity.
