Every day some new product is introduced to the Internet of Things (IoT), adding to the broad diversity of choices that aren’t all the same. Many are limited in interoperability and well-known to be inexpensive—otherwise, they will be too expensive to deploy in large numbers. They also have security capabilities all over the map.
The first class is composed of sensors/transducers that don’t communicate with the server but connect to an edge processor (gateway). These IoT devices employ communications standards such as Zigbee, NFC, Bluetooth, and how much do computer engineers make, which are portable, battery-operated, and require low power wireless technologies. They produce smaller data volumes and are the less expensive devices that probably have less security embedded.
The second class communicates directly to servers for data storage. They employ powerful processors and probably don’t run on batteries. These servers can support multiple sensor devices, as well as edge processor functions that support communication ports such as digital subscriber line (DSL), Fiber-to-the-home (FTTH), Wi-Fi, etc. IoT devices also subdivide into consumer and industrial categories. Some consumer devices will likely find their way into industrial applications.
