France’s Bouygues Telecom, and O2 and Orange in the UK, have become the latest operators to announce femtocell deployments, reports Total Telecom, bringing the worldwide total to 43 carrier deployments. O2 has deployed 1,500 femtocell devices in one London apartment block, the world’s densest femtocell deployment. "The technology is proving to be a vital tool for improving mobile coverage and increasingly importantly, capacity too," said Small Cell Forum chairman Simon Saunders.
