LTE-M a.k.a. Rel-13 Cellular IoT

Some months back I wrote about the LTE Category-0 devices here. While Rel-12 LTE Cat 0 devices are a first step in the right direction, they are not enough for small sensor type of devices where long battery life is extremely important. As can be seen in the picture above, this will represent a huge market in 2025.


To cater for this requirement of extremely long battery life, it is proposed that Rel-13 does certain modifications for these low throughput sensor type devices. The main modification would be that the devices will work in 1.4MHz bandwidth only, regardless of the bandwidth of the cell. The UE transmit power will be max of 20dB and the throughput would be further reduced to a maximum of 200kbps.

The presentation, from Cambridge Wireless Future of Wireless International Conference is embedded below:

Good intro to LTE MTC evolving standards. Here is look at IoT from an alphabet soup of standards and ecosystems - http://www.telecom-cloud.net/iot-journey-smart-sensors-apis-big-data-and-standard-bodies/
