5G NR Base Station Types
As per 3GPP specification TS 38.104, the NR Base Station can be classified in following categories considering conducting (cabled) and radiating (OTA) requirement reference points: Base Station type 1-C Base […]
5G End to End KPI – Accessibility, Integrity and Utilization
A Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively a network is serving the user. In simple terms we can say KPIs describe the fitness level […]
5G Key Performance Indicator Definitions Template by 3GPP
3GPP specification TS 28.554 has given a template for end to end KPIs of 5G System. This template is valid for for both NR-Radio Access Network and Core Network. Below […]
5G NR Interfaces X2/Xn, S1/NG, F1 and E1 Functions
In LTE networks, X2 and S1 interface are defined as an interfaces between RAN nodes and between RAN and Core Network. 5G is expect to operate in two modes as […]
