The difference between embedded systems and wireless embedded systems
What is the difference between embedded systems and wireless embedded systems? Why should we choose embedded systems?
An embedded system is a combination of a microchip and software to perform a specific task, embedded into a manufactured product. In the past, if a device needed to communicate to other devices or to a network, a wired connection was the only feasible approach. As an example, a modern thermostat usually contains a dedicated microcontroller to manage the display and user interactions, and communicates with your furnace via a wired link.
A wireless embedded system adds a wireless communication link to the mix. The cost of silicon chips continues to fall exponentially over time, and in many cases, the cost of RFICs (Radio Frequency Integrated Circuits) is lower than that of the wire and connectors that they replace.
