Understanding L1/L2 Triggered Mobility (LTM) Procedure in 3GPP Release 18

In an earlier post we looked at the 3GPP Release 18 Description and Summary of Work Items. One of the key areas was Further NR mobility enhancements, where a new feature called L1/L2-triggered mobility (LTM) has been introduced. This procedure aims to reduce mobility latency and improve handover performance in 5G-Advanced. Mobility has always been…

3GPP Release 18 Signal level Enhanced Network Selection (SENSE) for Smarter Network Selection in Stationary IoT

As 5G evolves and the number of deployed IoT devices increases globally, efficient and reliable network selection becomes ever more critical. Particularly for stationary devices deployed in remote, deep-indoor or roaming environments, traditional selection mechanisms have struggled to provide robust connectivity. This has led to operational challenges, especially for use cases involving low-power or hard-to-reach…

Reigniting Growth in the Telecom Industry with AI and Cloud

The telecom industry is at a crossroads. While demand for connectivity continues to surge, operators face stagnating revenues, rising costs, and increasing competition. In his keynote at the Brooklyn 6G Summit 2024, Manish Singh, CTO of Telecom Systems Business at Dell Technologies, outlined a compelling vision for how AI and cloud-native networks can reignite growth…

Is 6G Our Last Chance to Make Antennas Great Again?

At the CW TEC 2025 conference hosted by Cambridge Wireless, veteran wireless engineer Moray Rumney delivered a presentation that challenged the direction the mobile industry has taken. With decades of experience and a sharp eye for what matters, he highlighted a growing and largely ignored problem: the steady decline in the efficiency of antennas in…

Seamless UE Context Recovery (SUECR) in 3GPP Release 18

3GPP Release 18 introduces a wide range of enhancements across the 5G system, from energy efficiency and XR optimisation to AI-powered features. Among these developments is a practical but important addition known as Seamless User Equipment Context Recovery (SUECR), designed to handle situations where a device temporarily goes offline. When a device such as a…

A Beginner’s Guide to the 5G Air Interface

Some of you may know that I manage quite a few LinkedIn groups, and I often come across advanced presentations and videos on LTE and 5G. From time to time, people reach out asking where they can access a free beginner-level course on the 5G Air Interface. With that in mind, I was pleased to…

Evolution and Impact of Cellular Location Services (LCS)

Location Services (LCS) have been standardized by 3GPP across all major generations of cellular technology, including 2G (GSM), 3G (UMTS), 4G (LTE), and 5G. These services enable applications to determine the geographical location of mobile devices, facilitating crucial functions such as emergency calls, navigation, and location-based advertising. The consistent adoption of standardized protocols ensures interoperability,…

Dummy Loads in RF Testing for Dummies

I have spent many years working in the Test and Measurement industry and have also worked as a hands on engineer testing solutions, and as a field engineer testing various solution pre and post deployment. Over the years I have used various attenuators and dummy loads. It was nice to finally look at the different…
