LTE-M for IoT in Mobile Networks
LTE-M, also known as LTE-MTC or LTE-eMTC, is a variant of 4G LTE (Long-Term Evolution) technology that is suitable for the Cellular Internet of Things (CIoT), and Machine-to-Machine (M2M) communications.
It is one of the key technologies enabling the Cellular Internet of Things (CIoT) ecosystem.
LTE-M is designed to have low power consumption. This allows IoT devices to operate for several years on a single battery. As it uses techniques like power-saving mode, and extended discontinuous reception (eDRX).
Compared to other IoT technologies such as NB-IoT, LTE-M offers higher data rates, and lower latency, but it has device higher power consumption.
Also this technology supports device mobility, allowing IoT devices to maintain connectivity even when moving at low to moderate speeds.

5G Network Slicing
5G Network Slicing means that, to divide the physical network that the operator is having, into different logical networks with different characteristics. Every logical network, is a network slice. And every network slice has different characteristics from the other network slices, so that it can serve a certain type of services accordingly. Every network function…

What is an ‘EPS Bearer’ in LTE ?
During 'LTE attach' procedure, the network establishes this EPS Bearer between the UE and the PGW. The PGW assigns an IP address for this Bearer. The UE uses this IP address, in order to communicate with the PDN. In addition, the PGW assigns a QoS for this Bearer, which guarantees the QoS for the data…

LTE (4G) Network Architecture
LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…
