What is OpenRAN

As an integral part of wireless communication, radio access networks (RAN) connect computers, smartphones, tablets, and similar remotely-controlled devices to various parts of a network through radio connections. The user devices are designed with built-in RAN. The RAN connects the devices to a telecom network wirelessly by managing resources across radio sites. But the providers

Attach Failures in 5G – Part 2

May 27, 2020

Phone with no signal

In the last blog, we discussed the failures encountered while validating devices or base stations in the ENDC mode. We summed up issues that can arise due to incompatibility in the UE and Network capabilities, incorrect measurement configuration and report exchanged and problems in the CG-config sent by the base station to the UE. In

Attach Failures in 5G – Part 1

Person angry due to Attach Failures

Introduction As discussed earlier in the previous whitepaper regarding the validation of NSA and SA deployment modes, the ENDC mode requires coordination between the existing LTE nodes and new nodes (e.g. gNB), the introduction of a new radio, and several modifications in the messages. Consequently, during the initial conformance and feature testing, most often one

Dynamic Spectrum Sharing (DSS)

Dynamic Spectrum Sharing

Introduction Spectrum reframing from 2G to 3G and then to LTE was a slow and comparatively complex process and also expensive. It was not possible to share the spectrum between different technologies. Spectrum reframing from LTE to 5G will be simpler with DSS.   Dynamic Spectrum Sharing (DSS) is a technology that will allow both 4G

URLLC – What to know before embracing it

February 29, 2020


As we know, to meet the diverse industrial and market demands, the ITU has classified 5G into URLLC, eMBB and mMTC. As data traffic requirements are increasing every day ranging from mission-critical to massive machine connectivity, the anticipation of 5G is growing at an exponential rate. Even though such requirements open new doors to exciting

Why FR1 should be preferred over FR2 for 5G deployment?

February 5, 2020

Why FR1 over FR2? As we know that more availability of spectrum data means more network capacity, which leads to faster data rates and better user experiences. With 3GPP release 15 and 5G NR technology, it is going to provide channel bandwidths of up to 100MHz in sub 6 GHz spectrum and up to 400

Evolution of NB-IoT and it’s Implementation

November 18, 2019

Narrowband internet of things (NB-IoT), a recent cellular radio access technology based on Long-Term Evolution (LTE) introduced by Third-Generation Partnership Project (3GPP) for Low-Power Wide-Area Networks (LPWAN). The main motive of NB-IoT is to support massive machine-type communication (mMTC) and enable low-power, low-cost, and low-data-rate communication. Narrowband-IoT Standard and Releases Early in 2014, the LPWAN

Transition Towards 5G

October 10, 2019

Today’s digitally smart society is moving towards a new generation of communications, the 5G. The race is officially on to lead in delivery of live 5G services. But is the industry truly ready to move as fast as it says it is? The move towards 5G won’t be a simple network upgrade. It’s a long & packed

UE Simulator (LTE, 5G, NBIoT)

August 30, 2019

In today’s world, cellular network users want and expect superior service and performance with high quality of service and network speed in giga bits per second, for which extensive and frequent access RAN testing needs to be done. Simnovus UE Simulator solutions are capable of simulating and testing several devices and user equipment to recreate

5G Playground & Network Emulation

5G Network Structure The below network diagram describes the 5G architecture which consists of all RANs, aggregator, IP network, nanocore etc. network elements. As shown in the figure the 5G network uses flat IP concept so that different RANs (Radio Access Networks) are able to use the same single Nanocore for communication. RANs supported by
