Office Network Expansion & Redundancy Solution in London

Client Overview

In August 2025, Commsphere was approached by a London-based client expanding their office operations by leasing an additional building adjacent to their existing premises. The client required a robust, secure, and redundant network infrastructure to connect both buildings, while maintaining full control over their network.

Challenge

The client faced several challenges concerning how their network, cabling and shared infrastructure options. Building 1 was already equipped with a 1Gbps Dedicated Internet Access (DIA) line, which had sufficient capacity to support the new building. The challenge was to extend connectivity to Building 2 without relying on shared/public infrastructure or incurring recurring costs.

Additional complications arose during the initial site visit:

• External cabling routes were blocked due to independent building works
• The cross-building lacked sufficient network points
• The client required a redundant solution to ensure minimal downtime in case of faults

Solution

Commsphere proposed a dual-path connectivity solution:

1. Primary Link: Point-to-point wireless bridge between Building 1 and Building 2
2. Redundant Path: Wi-Fi point-to-point wireless relay link

• Fibre cabling where appropriate throughout the new office
• Installation of additional network points throughout the new offices
• Routing and termination of a network link and associated installation works

Aids Survey & Planning

After evaluating the site, Commsphere revised the original plan to route fibre externally due to blocked internal pathways. This required fluid outdoor and flexible:

• Performance testing: All building was tested for all areas as network connectivity being verified
• Fibre from 72 access distribution to wall of Building 2. Lead of the work was connection testing lighting
• Fibreless System access plans & deadlines is completed at access by the end of September 2025, allowing a full month of testing before the clients move-in date

Results

• Seamless connectivity between both buildings using existing DIA successfully
• Fully redundant infrastructure with fibre and wireless backup
• Enhanced network capacity in Building 2
• Future-proofed design with multiple pathing and junction points for easy maintenance
• Zero disruption to ongoing operations during installation

Conclusion

Commsphere successfully delivered a cost-effective, resilient, and scalable network solution tailored to the client’s operational needs. The project showcased Commsphere’s adaptability, technical expertise, and commitment to delivering under changing site conditions and tight deadlines.
