Jersey Telecom (JT), supported by Ericsson, has announced the commencement of its approximately £80 million project to deploy a new 5G mobile network across the island.

After nearly two years of planning, trials, and pilots, the first phase is now live in Area 1 (St Ouen), marking a significant milestone in the island’s digital infrastructure upgrade.

The rollout involves replacing the existing 3G network and upgrading the current 4G infrastructure, which is based on ZTE equipment now reportedly deemed a security risk by the UK government and others. Early testing indicates substantial improvements in signal strength, coverage, and download speeds.

The phased deployment will continue over several months, with full 5G Standalone (SA) service expected by the end of 2025, providing end-to-end 5G connectivity without reliance on 4G networks. The rollout plan includes specific regional targets from May through November, with key areas such as St John, Trinity, St Martin, and Jersey’s town centre scheduled for phased launches.

Additionally, JT has invested in core network upgrades in Guernsey, prepared to extend the new 5G capabilities once spectrum licensing is established by regulators.

JT CEO Daragh McDermott emphasized the company’s commitment to continuous innovation and future-ready networks, while Deputy Lyndon Farnham highlighted the benefits of enhanced service, security, and resilience for residents and businesses.

Once completed, Jersey’s 5G network will complement the island’s full-fibre broadband infrastructure and will be among the few globally to feature end-to-end Ericsson 5G technology.
