Iperf : A Tool for Network Testing
Iperf or IP performance is a utility for testing network performance and its tuning. It is a cross-platform (windows, linux) tool which can provide standardized measurement results for any network […]
O-RAN – Fronthaul Delay and Its Management
O-RAN Split Option 7-2x, introduced a functional split between O-DU and O-RU within the PHY Layer of the radio interface. This split cause some delay in transmission and reception of […]
5G NR Modulation and Coding Scheme – Modulation and Code Rate
For any communication technology, Modulation and Coding Scheme (MCS) defines the numbers of useful bits which can carried by one symbol. In contrast with 5G or 4G, a symbol is […]
NB IOT Peak Data Rate Calculation
We have seen in different literature that Narrow Band IOT (NB-IOT) release 13 technology peak downlink data rate is 170 kbps and pplink data rate is 250 kbps, do know […]
5G NR System Information Type#1 – SIB 1
In 5G NR, System Information Block #1 (SIB#1) carries information relevant when evaluating if a UE is allowed to access a cell and defines the scheduling of other system information. […]
CPU Pinning in Telco Cloud
Whole world telecom infrastructure (RAN, Core and IMS) adapting towards the cloud and virtualization where the network nodes are sharing virtual resources (Compute, storage, networking etc.) for running application on […]
5G NR SA Registration/Attach Call Flow
A 5G Stand Alone also know as Option 2, architecture includes 5G UE, gNB and 5G Core Network. In this post we will discuss about 5G SA Registration Call Flow […]
5G NR Measurement Events
In any telecom technology (2G, 3G, 4G or 5G), mobility (handover) decision whether mobile device will be handover or not is taken by by base station based on measurement reports […]
5G mmWave 28 GHz Band Link Budget – n257
The combination of 5G NR technology and millimeter wave bands pioneer a new level of mobile performance with ultra-high speeds and low latencies. Momentum behind 28 GHz is growing, with […]
5G NR Inactive-RNTI (I-RNTI) for RRC_INACTIVE State
In 5G NR, 3GPP specification has introduced an RRC state as RRC_INACTIVE state. The aim of RRC_INACTIVE state is to achieve power saving with acceptable access latency, and is suitable […]
