When you hear LTE you probably start thinking of fast speed, high bandwidth, HD video, your favorite apps...lots of data. But, LTE can also be dialed back to create power-efficient cellular connected devices. This is a useful solution for connecting IoT devices like sensors and actuators to the Internet since they dont transmit lots of data and operate under strict energy budgets.
Did you know theres more than one type of LTE?
Within LTE there are multiple categories as defined by the global cellular standards body, 3GPP
. Some of the categories are still in the process of being developed but one thing is clear, there will be split in the evolution of LTE. In one direction, LTE will continue to increase speed and bandwidth for smartphones and other data-hungry applications. In the other direction, well see cellular providers accommodating machine-to-machine communication with LTE designed for low power, low data, and low cost.
In the video below, Digi CTO, Joel Young, provides an in-depth look into how LTE technologies are evolving to accommodate the various needs of cellular connected devices.
Were still in the early days of LTE for machines, but more advancements in LTE for M2M/IoT are on the horizon. Check out our technical brief "M2M in an LTE World
," for more details on how these LTE categories differ and what it means for M2M/IoT product designs.
