How we approach it
Wi-Fi planned for the building it serves
Reliable wireless comes from designing to the space and the way it is used, then keeping the network tuned as that use changes.
- Designed to the space and use
- Coverage intent is shaped around the building and its usage during design and BOQ / scope alignment. Detailed placement and topology stay in the design set, not on the page.
- Verified on handover
- Before handover the network is tested against the agreed intent, so what is delivered matches what was planned.
- Tuned as use grows
- Device counts and floor layouts shift over time; an AMC scope can include periodic wireless health checks and firmware upkeep so performance holds as the estate changes.
/ The discipline, in detail
How we approach enterprise wi-fi.
An access point's catalogue square-footage and a real building's coverage map are unrelated documents. We site-survey every deployment with Ekahau or AirMagnet, model the building's RF before the first AP is mounted, and place hardware to the actual cell-edge SNR your devices need. Roaming is tuned, channel plans are documented, and the controller is configured to the security and segmentation policy the organisation actually has — not the one pasted from a default template.
On record
Every enterprise wi-fi engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.

Density before hardware
Access-point density and channel planning across floors — coverage is designed from client counts and walls, not from a catalogue page.

Power over Ethernet (IEEE 802.3)
IEEE-standard delivery of low-voltage DC power over the same Cat-class cable as data. PoE+ delivers up to 30 W; PoE++ Type 3/4 up to 90 W — sufficient for IP cameras, APs, VOIP phones and small displays.
Concept
Cat6A Structured Cabling
Augmented Category 6 structured cabling — 10 Gbps over the full 100 m channel, rated for 25 years of service. The default for any new commercial or premium-residential cabling layer.
Concept
Wi-Fi 7 (IEEE 802.11be)
Current generation of Wi-Fi. Adds 6 GHz band, MLO multi-link operation and 320 MHz channels. Default for new premium deployments where dense-room capacity is the binding constraint.
Concept
IEEE 802.3bt (PoE++)
Power-over-Ethernet at Type 3 (51 W device) and Type 4 (71.3 W device) classes — the power floor for Wi-Fi 7 APs, large PTZ cameras with heater, AV-over-IP encoders and small powered displays. Shared switch budget, per-port negotiation.

/ Plan it right
Enterprise Wi-Fi — getting the brief right.
Common mistakes to avoid
- Estimating access-point count from square footage instead of an RF survey — wall construction and ceiling height decide coverage, not floor area.
- Designing for coverage when the real constraint is capacity — concurrent devices per area is what breaks Wi-Fi in dense offices, classrooms and hotels.
- Mounting APs where the ceiling is convenient rather than where the RF model puts them, then wondering why roaming breaks between floors.
- Leaving cabling and PoE budget out of the wireless design — every AP is also a cable run, a switch port and a power draw.
- Running one flat SSID for staff, guests, cameras and devices with no segmentation policy behind it.
What to share before a quotation
- Floor plans, with wall construction and materials noted where known.
- The device population — concurrent users, device types and the applications that matter (voice, video, point-of-sale).
- Existing switch infrastructure and its PoE headroom.
- The security intent — guest access, 802.1X, and how cameras and IoT devices are segregated.
- Coverage expectations for outdoor areas, lifts, stairwells and back-of-house.
/ Frequently asked
Enterprise Wi-Fi — what buyers ask first.
How many access points does a 10,000 sq ft office need?
A 10,000 sq ft office typically needs 6–14 access points, depending on wall density, ceiling height and the number of concurrent users per square foot. We do not estimate — we predict in Ekahau against the floor plan and validate on site.
How do you design a Wi-Fi network properly?
Through a predictive site survey using the actual building floor plans, then a post-install validation survey with a calibrated Wi-Fi analyser at every workstation. Access points are sited to actual cell-edge SNR, not to access-point catalogue square-footage. This is the single most important design decision and the one most often shortcut.
How many access points does a typical office floor need?
Roughly 1 AP per 1,500–2,500 sqft for office work, 1 per 800–1,200 sqft for high-density (boardrooms, classrooms, conference auditoria), 1 per 3,000–4,000 sqft for warehouse-low-density. The site survey adjusts these benchmarks to the actual building.
Aruba, Cisco or Mist (Juniper) for enterprise Wi-Fi?
Aruba CX and Mist are the two strongest premium choices — Mist's AI-driven optimisation is genuinely useful for large deployments; Aruba's policy-driven security model is a defining strength on the platform. Cisco Catalyst is the safe enterprise default. We deploy all three.
Should guest Wi-Fi be on the same APs as staff Wi-Fi?
Yes, but on separate SSIDs with VLAN-isolated traffic and a captive portal for guest. Multi-SSID on the same AP hardware is standard; running separate AP hardware for guest is a waste of capital that does not improve security beyond what proper VLAN segmentation already delivers.
How do you handle Wi-Fi roaming for mobile-heavy environments?
Through 802.11k, 802.11r and 802.11v fast-roaming features tuned in the controller. For voice-over-Wi-Fi (VoWiFi) and real-time location services, we tune RF coverage to ensure -65 dBm at every position so handoff doesn't drop calls. Hospital and warehouse deployments need this discipline; office deployments can be more relaxed.
Which Wi-Fi and switching brands does TechnoGuru work with?
On the wireless side we work with Netgear, HPE Aruba, Ruckus and Ubiquiti, with PoE switching sized to power the access points, cameras and phones on the same fabric. The family is chosen against the site type — corporate floor, hotel, warehouse — rather than fixed in advance. Final make and model follow the area, floor count, wall material, endpoint count and bandwidth reviewed during the survey.
Can the Wi-Fi and switching double as the backbone for CCTV and AV-over-IP?
A properly sized PoE switching and cabling layer can carry Wi-Fi, IP cameras and AV-over-IP on one structured backbone with VLAN separation, which is more maintainable than parallel networks. Whether it should depends on the endpoint count, the bandwidth per stream and the headroom required, so we size it from the drawings and a survey. We do not promise a throughput figure before the design is validated on site.
