The Challenge: Construction Site Mobile Signal in a Steel and Concrete Environment
Why basements and steel structures block mobile signal
Plus
The importance of mobile connectivity on modern construction sites
During the construction of 2 Finsbury Avenue, reliable mobile connectivity was essential to support day-to-day site operations. However, as with many large commercial developments, the building structure presented significant challenges:
- Basement and sub-ground levels with little to no mobile signal
- Steel and reinforced concrete causing severe signal attenuation
- Multiple contractors requiring dependable communications
- A requirement for coverage across all major UK mobile networks
- The need for a temporary solution suitable for the construction phase
Crosby Electrical, working on behalf of Sir Robert McAlpine, required a specialist partner to design and deliver a solution that would ensure consistent mobile connectivity throughout the build, without relying on permanent infrastructure.
The Solution: Temporary In-Building Mobile Coverage for a Live Construction Site
Simpli-Fi designed and deployed a temporary in-building mobile coverage solution tailored to the construction phase at 2 Finsbury Avenue.
The Technology: Multi-Network DAS for Construction Environments
Temporary DAS deployment for construction sites
-
Nextivity Quatra 4000e multi carrier cellular DAS for 3G/4G/5G for voice and data services
-
Multi-carrier mobile coverage for all UK networks
-
Extending mobile signal into basement and sub-ground levels
-
Flexible mobile coverage aligned to the construction programme
This approach ensured seamless communication for site teams, even in areas traditionally affected by poor or non-existent signal.
The Results: Reliable Mobile Connectivity Across the Construction Site
The deployment delivered clear operational benefits:
✅ Consistent voice and data connectivity across the site
✅ Improved communication, safety and coordination
The solution supported productivity, safety and coordination throughout the construction phase of 2 Finsbury Avenue.

Frequently Asked Questions – Temporary Mobile Coverage for Construction Sites
Why is mobile signal often poor on construction sites?
Construction environments typically include steel frameworks, reinforced concrete, and deep basement levels, all of which severely block mobile signals. As buildings rise, external signals become weaker, making temporary in-building mobile coverage essential to maintain reliable voice and data connectivity on site.
What is temporary in-building mobile coverage for construction projects?
Temporary in-building mobile coverage uses specialist equipment such as Distributed Antenna Systems (DAS) to extend mobile signals throughout a live construction site. These systems provide multi-network cellular coverage for voice and data without relying on permanent infrastructure during the build phase.
Can temporary mobile coverage work in basements and sub-ground levels?
Yes. Temporary cellular systems are specifically designed to deliver basement mobile coverage, even in deep or steel-heavy structures. At 2 Finsbury Avenue, Simpli-Fi extended mobile signal into lower-ground and basement areas where natural coverage was unavailable.
Will temporary mobile coverage support all UK mobile networks?
It can. Simpli-Fi deploys multi-carrier in-building mobile solutions that provide coverage across all major UK networks. This ensures site managers, contractors, and visitors can connect using their own mobile providers without relying on hotspots or workarounds.
Is temporary mobile coverage suitable for live construction environments?
Yes. Temporary in-building mobile systems are engineered for active construction sites, offering robust, flexible deployments that can adapt as the building structure evolves. Solutions can be expanded, repositioned, or reconfigured as the project progresses.
What are the benefits of temporary mobile coverage on construction sites?
Temporary mobile connectivity improves:
- Site communication and coordination
- Health and safety responsiveness
- Productivity and operational efficiency
- Visitor and contractor experience
Reliable construction site mobile signal reduces downtime, safety risks, and dependence on unreliable alternatives.
Can temporary construction coverage transition into a permanent system?
Yes. Temporary solutions can often inform or integrate into a future permanent in-building mobile coverage strategy, supporting a smoother handover from construction to occupation.
Who typically deploys temporary mobile coverage on construction projects?
Temporary mobile coverage is commonly delivered in partnership with M&E contractors and principal contractors. Simpli-Fi regularly works alongside delivery partners such as Crosby Electrical to support major construction programmes with specialist connectivity expertise.
Need temporary mobile coverage for your construction project?
From basement levels to steel-heavy structures, Simpli-Fi designs and deploys mobile connectivity solutions that work from day one.
