C Spire has disclosed plans to invest USD1 billion over the next three years – the largest capital spend in the company’s history – as it seeks to accelerate the deployment of 5G wireless technology and all-fibre gigabit broadband in key parts of its service area. On the back of the investment, C Spire seeks to bring fibre broadband to over 200,000 homes and businesses in Mississippi and Alabama by end-2025. 5G, meanwhile, will be extended to nearly 600 sites representing over 60% of Mississippi; 300 of these sites should be live before end-2021.
