Wireless communications is the transfer of information between two or more points that are not connected by a physical cable. This technology uses electromagnetic waves to carry the signal over a distance, allowing for mobile communication and connectivity. Wireless communications encompass various technologies such as Wi-Fi, Bluetooth, cellular networks, satellite communications, and more. Research in this area aims to improve the speed, reliability, and security of wireless networks, as well as enable new applications and services such as internet of things (IoT) devices, autonomous vehicles, and smart cities. Key challenges in wireless communications research include spectrum management, interference mitigation, energy efficiency, and signal processing techniques.
