In a recent session on smart building cybersecurity, a student cheekily asked me "How did we ever connect anything before 5G?" At that moment I realized I might have been overdoing my 5G cheerleading recently. To atone, here are the key performance and cybersecurity attributes of the most commonly used connectivity technologies in smart home / smart building use cases... And 5G.
If you thought that the "traditional" home life is under heavy attack from digitization of media and constant communication, wait until you learn about the Internet of Things (IoT) and Smart Homes.
Our most personal spaces - our homes...
NFC is a short range two-way wireless communication technology that enables simple and secure communication between electronic devices embedded with NFC microchip. NFC technology operates in 13.56 megahertz and supports 106, 212, or 424 Kbps throughput. There are three available modes of NFC communication:
Read/write (e.g. for reading tags in NFC posters)
Card emulation (e.g. for making payments)
Peer-to-peer (e.g. for file transfers)
There is no need for pairing code between devices, because once in range they instantly start communication and prompt the user. NFC technology is power efficient - much more than other wireless technologies. The communication range of NFC is approximately...
