Low Power Wide Area Networks for IoT: SigFox, LoRa, LTE-M, 5G LP-WAN

[In collaboration with guest blogger Marc Espinosa]

The important topic of connectivity protocols was discussed in our previous IoT post, it is time to dive deeper into the telecommunications protocols underneath. The fact is that the technologies that enable the IoT architecture need to assume low power at the same time as the transmission via the long distances (meaning - lower frequencies). 
For example, if we need to cover a field, a campus, an entire building or turning a city smart, we will need a specific communication protocol. The truth is that ZigBee and 6LoWPAN do create a low-power and low-cost WPANs, but since the assets can be distributed in an pretty wide area - we need to include another variable to the equation: the range.
The following networks/technologies are called Low Power Wide Area Networks (LP-WAN). Regardless of the fact that the consumption of devices they are connecting is low, they actually cover a wide area network, making things easier and better to conn…

Understanding the IoT Protocols: MQTT, CoAP, ZigBee

[In collaboration with the guest blogger, Marc Espinosa]

Let's start with the messaging protocols, MQTT and CoAP, and consider which of the following open standard protocols should be considered for your implementation.

If you're looking for the right guide to gain a solid perspective of the IoT business, these lines might just be what you need. The IoT can be defined as the a system of interrelated devices (such as sensors) that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

So, how do all these "Things" speak among them? Which are the languages/communication protocols they use and which one should we choose? The answer might surprise you... it depends!

There are 2 types of open standard protocols that work for small devices:

Message Queuing Telemetry Transport (MQTT)Constrained Application Protocol (CoAP)

MQTT and CoAP are two of the most promising protocols for …
