UK telecom operator O2 is revolutionizing mobile network installations with Europe’s first pre-assembled mobile masts. By moving assembly and testing from on-site to a factory setting, O2 aims to enhance network deployment efficiency and reliability. This innovation supports large-scale rollout, aiding the UK carrier’s broader £700 million network transformation plan.
The first deployment in Sandwich, Kent, saw a significant reduction in installation time. The process that typically spanned two days was completed in just four hours. These pre-assembled sites enable faster and simpler installation, as most work is pre-done in controlled conditions, minimizing errors often encountered on-site.
Vecta Labs, an Australian company, collaborated on the pre-assembly design. The firm executes thorough validation using controlled testing, simulating environmental conditions such as wind stress, and checking for interference issues like Passive Intermodulation (PIM). These steps ensure the highest performance consistency and reliability once deployed.
Reducing the on-site connection count from about 100 cables to six considerably lowers installation errors—highlighting a commitment to maintaining consistent network performance across multiple sites. “The pre-assembly platform we have developed is designed for volume manufacturing and has the flexibility to cater for different site configurations and different radio ad component vendors,” said John Bonello, director at Vecta Labs.
This innovative method not only speeds up deployment but also promises improved network performance and ease of maintenance. Factory-tested and validated components mean maintenance teams can quickly replace parts and comprehend site configurations. This precise design intention reflects the broader trend in telecom toward standardized and industrialized build processes to manage increasing network complexities.
As 5G and future networks grow, pre-assembled mobile masts like these present a scalable, efficient approach pivotal for managing complex configurations. It’s an industrial shift suggesting pre-installation sector testing as vital for achieving the desired network quality.
Previously, Virgin Media O2 had already enhanced its network with more than 500 locations across the UK equipped with 5G Standalone (5G SA) technology. This deployment strategy demonstrates O2’s leadership in leveraging cutting-edge techniques to meet increasing connectivity demands efficiently.
