The 3rd Generation Partnership Project (3GPP) architecture has introduced a subsystem known as the IP Multimedia Subsystem (IMS) as an addition to the Packet-Switched (PS) domain. IMS supports new, IP-based […]
What is VoLTE Roaming? Architecture Options and Challenges
3GPP Releases, Main Features from 3G to 4G
3GPP specifications cover cellular telecommunications technologies, including radio access, core network, and service capabilities, which provide a complete system description for mobile telecommunications. In general, there are many wireless technologies […]
The Difference between SIBs in 4G and 5G
As you may know that UE can access the network if it can receive some of the System Information (SI) from the Cell (Mandatory). So Let’s understand the main difference […]
What is the difference between 4G Core and 5G Core?
In LTE Core Network, all data plane traffic must go through a single node type called Packet Data Network Gateway (P-GW). This centralized architecture is advantageous in terms of operation […]
Modulation and Signal Quality in LTE
Depending on the modulation technique, each symbol stands for bits and each data point represents a different bit pattern. QPSK, 16QAM, and 64QAM are used by LTE devices to modulate […]
Is There Compressed Mode in LTE?
During RRC_CONNECTED mode, if the eNodeB decides that the UE needs to perform LTE inter-frequency and inter-RAT monitoring activities, it will provide the UE with a measurement configuration which includes […]
LTE Radio Channels
Different channels are used for data to be transported through the LTE radio interface. These channels are used to separate the various types of data and allow the data to […]
