Whether it is IoT, M2M, or Industry 4.0, LoRa is one of the most popular wireless communication medium. LoRa is getting popular day by day and there are many LoRaWAN networks all around. It consumes very low power and can communicate over a long-range.
There are various wireless communication technologies used in building IoT applications and RF (Radio Frequency) is one of them. nRF24L01 is a single-chip radio transceiver module that operates on 2.4 - 2.5 GHz (ISM band).
Robots are used in many sectors like construction, military, manufacturing, assembling, etc. Robots can be autonomous or semi-autonomous. Autonomous robots do not require any human intervention and can act on their own according to the situation.
IoT has taken off in a big way with companies like Intel, Google and Samsung all rushing for a piece of the pie. The existence of devices such as the Raspberry Pi and NodeMCU has also led to the existence of a significant hobbyist community.
There are number of communication technologies available for interaction between IoT devices today, and the most popular ones are Wi-Fi and Bluetooth. But the problem with Wi-Fi and Bluetooth technology is high power consumption.
