Wi-Fi insights
Technical writing about the things that actually decide whether a network works: radio behaviour, survey method, device fleets and the trade-offs in between.
These articles are written by the people who carry the survey kit, not by a marketing agency. That means they are longer and less quotable than most supplier content, and it means they say when something is uncertain, when a vendor claim is overstated, and when the honest answer is that it depends on the building.
There is nothing to download and nothing gated. If a piece is useful, use it — including to challenge a proposal we have put in front of you.
Worth understanding before you specify anything
Physics, survey method and device behaviour — the parts of a Wi-Fi project that get decided early and cost the most to get wrong.
Business broadband is fast — so why is the WiFi still bad?
Full bars and a great speed test, but calls still freeze. Capacity, placement, power, interference and roaming — the real reasons business WiFi underperforms, and how to tell which one you have.
Read the articleEkahau Partner Day 2026
SEGwifi is an Ekahau partner. We spent the day in London with Open Reality, Ekahau's UK distributor, on the Ekahau software suite: the rebuilt Analyzer app, Speedtest Certified, and a first look at AI Pro 12, MCP and a new roaming tool.
Read the articleWhy warehouse racking kills 5 GHz
Loaded racking is not the same building as empty racking. Why a survey of a bare shed misleads you, what happens to RF in a narrow aisle, and why more access points at full power is usually the wrong answer.
Read the articleRoaming for handheld scanners and AGVs
Roaming is a decision the client makes, not the network. What that means for scanners, voice handsets and automated vehicles — and what 802.11k, v and r actually do about it.
Read the articlePredictive vs on-site surveys, honestly compared
Both are useful and neither is a substitute for the other. What a model can tell you, what it cannot know, and when a predictive survey on its own is genuinely enough.
Read the articleGuest Wi-Fi and captive portals
Separate SSIDs are not separate networks, airtime is shared whatever the SSID says, and SSID sprawl costs you capacity. How guest access is put together properly.
Read the articleMarina RF: designing over water
Water reflects, tides move the reflection, boats move everything else. Propagation over water, salt corrosion, pontoon mounting and getting power to a position 200 metres from the nearest building.
Read the articleWi-Fi 6E and Wi-Fi 7 in practice
What 6 GHz gives you, what it costs you, and why a 6E design usually needs more access points than the 5 GHz design it replaces. The client fleet decides this, not the datasheet.
Read the articleLet's find out what your Wi-Fi is actually doing.
Book a survey and you get measured data, a design you can build to, and a number you can budget against — not an opinion.
Our cabling, containment and power are installed under the group's accreditations — NICEIC, Constructionline Gold, CHAS and SafeContractor, held by The Specialist Electrical Group Ltd.

Tell us about the building and what is going wrong. We will come back within one working day with the survey that answers it — or tell you that you do not need one.
