The stand was busy from day one and the excitement surrounding the exhibits on show is testament to the appetite for continued advancement in these areas.
Our Research Showcase: All-Spectrum Connectivity
Traditional Wi-Fi is now overcrowded, slow, and prone to interference which results in poor experiences and is limiting when it comes to modern levels of demand and newer technologies. This is the reason for our research. Here at HASC, we are focused on how to combine wired and wireless internet technologies to achieve optimal end-to-end connectivity so that the industry can continue to grow.
Our research showcase provided an opportunity for visitors to gain access to the world’s most cutting-edge research in the field of all-spectrum connectivity, telecoms technology and the UK’s developing communications infrastructure.
Here’s a glance at some of the great projects we presented at the show.

“When the opportunity arose to attend the mammoth event that is Mobile World Congress 2025, I jumped at it. Cutting-edge technology from across the communications world condensed into one room, or more like eight aircraft hangars!
Having joined Queen’s University Belfast last year as a Research Fellow in Terahertz Channel Modelling, I was particularly interested in gauging future market trends. What applications are companies considering in the wider spectrum?
One exciting example was a demo from Elmo and Nokia, where attendees were given the chance to drive a car that was 3,000 km away using a 5G link. Novel uses such as this will continue to drive innovation across the spectrum, and keep researchers like me entertained!” – Vanessa Wood
