Car Parks, Walkways & EV Charging
Underground and multi-storey car parks are among the worst signal environments in any building. With EV charging now requiring app-based payment and authentication, reliable mobile connectivity in car parks has become essential — not optional.
- Reliable signal in basement and underground car parks
- Supports EV charging app authentication and contactless payment
- Coverage in walkways, stairwells and lift shafts
- Works across all UK networks simultaneously
- Enhances visitor safety with reliable emergency call capability
Do signal boosters work in car parks, walkways and EV charging?
Yes — Nextivity Cel-Fi systems bring reliable mobile signal into underground and multi-storey car parks, so drivers can pay by app, authenticate EV chargers and make emergency calls. Zonegen designs each system after a site survey, usually using a Cel-Fi QUATRA system across levels, ramps, stairwells and lift lobbies.
The problem
Why is mobile signal poor in car parks, walkways and EV charging?
Underground levels
Basement car parks are surrounded by earth and concrete that block outdoor signal completely.
App-based parking and EV charging
Pay-by-phone parking and EV charge-point apps fail without signal, frustrating drivers and losing revenue.
Driver safety
Stairwells, lift lobbies and lower levels need signal for emergency calls.
Long, open structures
Multi-storey decks are large, so coverage has to be distributed level by level.
The solution
Which signal booster is right for car parks, walkways and EV charging?
Zonegen recommends the system after a free consultation — never more than your building needs. Prices shown are starting prices; your exact price is confirmed after consultation.
Cel-Fi GO G43
From £5,995
Multi-operator booster — EE, O2 and VodafoneThree from one unit.
Best for: Small basement car parks and single-level areas — all three networks.
Cel-Fi QUATRA EVO
Quoted after survey
Active DAS hybrid for 1 or 2 networks over CAT6 with Power over Ethernet. Up to around 6,000 m² per Network Unit, about 12,000 m² with a Fibre Hub.
Best for: Multi-level car parks where one or two networks are needed.
Cel-Fi QUATRA 4000e
Quoted after survey
Enterprise system for all UK networks. Up to 12 Coverage Units per system, and the Fibre Range Extender bridges up to 2 km between buildings.
Best for: Large public car parks needing every UK network.
How it works
How does a Zonegen installation work?

Free consultation
Tell us about the building, the signal problem and which networks you need. You get a price guide with no obligation.
- 2
Site survey
An engineer tests signal inside and out, assesses construction and plans cable routes. The survey cost is refunded if you go ahead.
- 3
Installation
Your Cel-Fi system is installed neatly and commissioned. Small sites are usually done in a day; larger sites are scheduled around you.

Testing and aftercare
Signal is tested throughout before handover. Optional monitoring keeps an eye on performance remotely.
FAQs
Questions about signal boosters for car parks, walkways and EV charging
Does a booster support EV charging app authentication?
Yes. EV charging apps and pay-by-phone parking need mobile data. Boosting signal at charging bays lets drivers authenticate and pay reliably.
Can you get signal into an underground car park?
Yes. A donor antenna captures signal at street level and the system distributes it through each level, ramp and stairwell.
Will it help emergency calls in the car park?
Yes. Better coverage on all boosted networks makes it far more reliable to call for help from lower levels, stairwells and lift lobbies.
Will EV chargers with built-in SIMs benefit?
Yes, for chargers whose SIMs use a boosted network. This can reduce offline chargers and failed sessions.
How much does a car park signal booster cost?
Car parks are sized to their layout, so Zonegen quotes after a site survey. The survey cost is refunded if you go ahead.
