smartcitiesLike many things in our lives, and as a result of the technological revolution, cities are subject to a constant transformation as they respond to the needs of the citizens who live in them and maintain or increase their sustainability. With the emergence of the IoT (Internet of Things), cities will undergo huge transformations aimed at both solving the problems which, in many cases, are already besetting them – as is the case of pollution – and providing people with more and better services.

A review of the physical principles behind the Wi-Fi /5G wireless revolution

wi-fiFollowing on from a previous article on DSL and its scientific bases, I now want to review the fundamentals of another technology: radio. As with a DSL, the ability to transmit data in any radio communications system – from the very first Marconi experiments to 5G networks – is bound by Shannon’s equation, based on the channel’s bandwidth and signal-to-noise ratio. In radio, we also have another interesting equation that can tell us the received signal strength when the transmitter power and frequency, antenna characteristics and distance to the receiver are known.
