05Design & Engineering
WiFi survey and design,
from survey to heat map.
A good wireless network starts with a proper survey. We survey, design, install and validate the network, with Ekahau-certified surveys and heat maps documented at every stage.

- Active
- Channel plans
- PoE
- Heat maps
01Overview
Wireless designed around the building.
Understanding the physical environment, interference sources and coverage requirements comes before any access point goes on the wall. We survey and model the space, design the network, install it, and then prove it with a post-installation survey.
We use professional survey tools and work with leading wireless vendors to design networks that meet your coverage, capacity and performance needs, from office floors to stadiums.

02Coverage model
See the coverage before the cable goes in.
An illustrative office floor. Switch between the predictive model, an active survey and the channel plan, and move across the plan to read the signal.
Predictive modelCoverage modelled from the floor plans and wall materials before anything is installed: eight access points on 5 GHz, designed to −67 dBm across the floor.
| AP | Channel | Area |
|---|---|---|
| AP-01 | 36 | Office |
| AP-02 | 52 | Open plan W |
| AP-03 | 44 | Open plan N |
| AP-04 | 100 | Open plan |
| AP-05 | 116 | Meeting 1 |
| AP-06 | 132 | Meeting 2 |
| AP-07 | 36 | Open plan E |
| AP-08 | 149 | Breakout |
03What's included
The full wireless cycle, with one team.
Each stage feeds the next, so the validation survey measures the network against the design it was built from.
- 01
Site surveys
Predictive and active surveys using professional tools, analysing coverage, interference, building materials and user density.
- 02
Network design
Access point placement, channel planning, power levels and SSID architecture, tailored to the building and its users.
- 03
Installation
Access points, controllers and supporting infrastructure mounted and cabled, with clean routing and PoE provisioned throughout.
- 04
Optimisation and validation
A post-installation survey, performance testing and fine-tuning, so the network delivers the coverage and throughput the design promised.
- 05
Documentation
Heat maps, access point schedules and channel plans, kept with the as-built drawings.
- 06
Ongoing support
Support after handover, as the building, its layout and its users change.
04How we deliver
Measured at the start and at the end.
A predictive model sets the design. Surveys on site check it before and after installation.
- 01
Requirements
Users, devices, applications and capacity, room by room.
- 02
Predictive design
A model built from the floor plans and wall materials.
- 03
Site survey
Assumptions checked on site and interference measured.
- 04
Install
Access points, cabling, controllers and PoE.
- 05
Validate
Post-installation survey, tuning, and heat maps at handover.

06Questions
Common questions
What is the difference between a predictive and an active survey?
A predictive survey models coverage from the floor plans and building materials before anything is installed. An active survey is measured on site with real equipment, to validate the design and find what a model cannot, such as interference or walls that differ from the drawings.
Do you install the access points and cabling?
Yes. We mount and cable access points, controllers and supporting infrastructure, with clean routing and PoE provisioned throughout.
How do we know the network delivers what the design promised?
We run a post-installation survey and performance tests, fine-tune channels and power, and hand over heat maps showing the coverage achieved.
Do you work in large venues as well as offices?
Yes. We surveyed, designed, installed and tested more than 450 access points for a football stadium with over 30,000 seats.
