At first, we need to identify the meaning of word EN–DC, It’s E-UTRAN New Radio Dual Connectivity. Simply it means the possibility of UE to get simultaneous data from LTE eNB and 5G gNB.  In EN-DC, the radio access network is composed of eNBs (eNodeBs) as the master node and gNBs (gNodeBs) as the […]

Dual Connectivity From the 1st Session of 5G RAN Training: How does Dual Connectivity improve the total BW. Also the limitation of using FDD for LTE and TDD for 5G NR. The Subcarrier Spacing plays an important role in expanding the total BW but it also has a limitation in the case of EN-DC. Did you […]

I summarized these #10 5G Learned Lessons from #5G_Asia and RCRWireless report about this big event  1- Operators should focus on replacing their legacy networks to pave the way to all IP networks, with new IT infrastructure rather than telco components.  2- A standalone 5G network requires a much more IT-centric approach to can support different use cases […]

15 kHz as 5G Baseline Numerology 5G RRC States In 5G and the previous generations, the device can be in different states depending on the traffic activity. NR device can be in one of three RRC states, RRC_IDLE, RRC_ACTIVE, and RRC_INACTIVE. The first two RRC states, RRC_IDLE and RRC_CONNECTED, are similar to the counterparts in […]

VoLTE is the all-IP method that tightly links the voice application to the LTE network to assure the best subscriber experience in terms of performance, reliability, interoperability and global roaming. The Value of VoLTE It integrates voice with 4G LTE to ensure the critical reliability and quality of that voice service. It ensures subscribers continue […]
