New Course | 2G to 5G – Evolution, Architecture and Features

This new course presents an introduction to 3GPP networks, the system architecture and evolution, as well as selected network procedures and features. The course presents similarities and differences between different 3GPP system generations. Basic architecture, terms, concepts, procedures, radio technologies, and the core network functions are introduced. With the 2G and 3G being phased out, […]
5G Standalone Architecture and Features

This course provides an overview of the 5G Standalone (SA) network architecture and features as specified in the 3GPP standards.
It examines the architecture and key components of both the Access and Core Networks, addressing deployment scenarios for Non-Standalone (NSA) and Standalone (SA) modes.
Webinar | Public Safety Services in 5G

This webinar presents the 5G 3GPP solution for the public safety services. It introduces the major radio and core network features in the 5G Standalone deployments designed to fulfill the stringent Quality of Service requirements of critical communication services. Both access and the core network features that enable low-latency, high-priority communication for fast-response verticals are […]
Five Thoughts from the Big 5G Event

The first post-pandemic Big 5G Event was held in Austin, Texas in late May 2022. Apis Training was there, talking to customers and listening to speakers from the industry. With up to five parallel tracks, it was impossible to cover more than a fraction of the interesting sessions. Still – these are some of our […]
About 4G and 5G Interworking

As the evolution of 3GPP system continues, there are more and more 5G network deployments all over the world. The latest generation of the mobile system offers technological possibilities for a range of new services and applications: higher connection speeds, more Internet of Things devices and applications, Augmented/Virtual Reality, smart factories, vehicle communication with other […]
Open RAN – What is it and Why?

A few telecom generations ago, Radio Access Network (RAN) equipment was typically provided by a quite small number of telecom equipment manufacturers. There was Ericsson, Nokia, Huawei, Siemens, Alcatel, Lucent, Nortel, Motorola and a few more. Although there were standardized interfaces – by ETSI/3GPP – from BTS to BSC (in 2G) and Node B to […]
About Voice in 5G

Mobile operators have been expanding their customer base for a few years now, providing connectivity for an ever-growing variety of services and applications. Internet of Things, Augmented/Virtual Reality, smart factories, communication between vehicles – all of these create new business opportunities. However, in this new connected world, the transportation of voice calls remains the basic […]
Multi-access Edge Computing (MEC) and 5G

Edge computing is a concept that: European Telecommunications Standards Institute (ETSI) is leading standardization activities around Multi-access Edge Computing (MEC). MEC provides compute and storage resources for applications geographically close to the end users. This enables high-bandwidth, low-latency access to services. Real-time radio network information can be used to optimize and adapt the services to […]
The native 5G network monitoring: NWDAF

Among the numerous Network Functions defined by 3GPP for the 5G System there is a very interesting one – the Network Data Analytics Function (NWDAF). With it the network and user monitoring, traditionally handled by proprietary monitoring tools, becomes native to the 5G.
Access Networks for the 5GC in R16 3GPP standards

The 5GS System (5GS), just as the previous mobile telecom systems, consists of the Access Network (AN) and the Core Network (CN).
