Under the terms of the partnership, The Cloud will engineer a comprehensive Wi-Fi network to ensure blanket coverage for the busy corporate hub.
With plans to launch the system within the next few months after installation in lamp posts and street signs is complete, workers in the City with enabled hardware should soon have complete wireless access.
City of London's policy committee chairman Michael Snyder hailed the move as a key development for one the worldâs biggest financial centres.
"City workers and visitors will be able to use wireless broadband to work more efficiently; staying in touch with their office via hand-held devices while on the move," he said.
"The City is a fast-moving and dynamic environment and we are responding to the increasing time pressures faced by City workers by providing the technology for them to stay up to date, wherever they are."
The Cloud recently unveiled plans to establish wireless hotspots in nine cities across the UK, including Cambridge, Manchester and Birmingham, as the technology continues to expand.
