We are entering the era of Internet of Things (IoT) devices, where each device connects remotely to one another, and the world wide web. This makes them smart in the way of integration to Artificial Intelligence, Machine learning and Data analysis. There are number of network protocols that facilitate this peer to peer communication be it ZigBee, Matter etc. More on that later. What is Bluetooth Invented in 1994 by Ericsson and widely used, Bluetooth allows for short distance communication, within 10 meter radius. The data speed is between 1 Mbps and 3 Mbps. The bandwidth is in the range of 2.4 GHz to 2.485 GHz. Frequency Hopping Unfold Spectrum This is the underlying tech used in Bluetooth. Data signals by default have low frequency, and high bandwidth. This makes them prone to distortion, affecting long distance transmission. Also the receiving antennas have to be large in size which is a limitation for mobile phone...
