Decoding the Triangle
Before we get to understand the three essential elements of the 5G triangle, let us get you some backdrop!
Are you aware of the force that makes the use of mobile phones a seamless affair even when you’re traveling outside your home country? Well, the credit goes to the International Telecommunication Union (ITU), who is responsible for laying the sets of global ICT guidelines. For 5G, ITU collaborates with the 3rd Generation Partnership Project (3GPP), which develops technical standards. Together, they established eMBB, URLLC, and mMTC—key innovations that define 5G’s capabilities. Here, let us explore in detail what is mMTC.
Massive Machine-Type Communications (mMTC)
This concept can be thought about as connecting a huge or as the name suggests, a massive number of things across the IoT spectrum. mMTC primarily focuses on connecting a large (really large) number of devices in each location/area. Quantifiably, this can be up to 1 million devices per square kilometer (now that’s a massive number in the most superlative form). But the point to remember is that these devices are the ones with low data requirements and low energy consumption.
What does this exactly mean? Here are a few instances that can clear the air. By utilizing a large number of connected sensors, potential mMTC applications could include scenarios such as smart agriculture. In this context, sensors could be employed to monitor and respond to small changes in growing conditions across a wide area. This would allow for targeted and near-real-time responses aimed at optimizing growth rates.
Additionally, the technology could facilitate similar functions in urban environments, allowing for near-real-time data collection and response. This could aid in traffic management, the optimization of electric grids, as well as in factory settings for production management, quality assurance, and shipping. Furthermore, the technology could be utilized in shipping fleets to monitor routes, efficiency, and maintenance needs, among other potential applications.
