Understand Wi-Fi first
then solve problems on site

Observe conditions at actual seats in glass meeting rooms, corner workstations and pantry areas. Signal bars cannot replace application testing.

Coated glass, metal frames and new partitions can change propagation paths. Compare doors open and closed, and usage locations on either side of partitions.

When several meeting rooms use video conferencing simultaneously, check active clients, channel use and the internet uplink first; adding APs alone is not the answer.

Take the actual laptop or voice device from a workstation to a meeting room and observe AP transitions and application continuity.

Housing-estate flats, back rooms in older walk-up buildings and studies have different conditions. Observe the bedroom, work area and locations of regularly used devices first.

Metal gates, fitted cabinets, refrigerators and structural walls may obstruct signals. Compare conditions before and after moving the router to an open location.

Streaming, downloads, smart-home devices and neighbouring Wi-Fi can affect the experience together. Compare local connectivity, busy periods and the internet connection separately.

When using mesh across rooms, assess backhaul and client switching behaviour. Sharing a network name does not mean every device roams seamlessly.

Test the checkout, ordering devices, tables and kitchen separately; do not assess the signal only in the centre of the premises.

Steel tables, refrigerated cabinets, metal shelving and glass display windows alter propagation paths. Check separately whether a microwave oven causes RF interference.

Guest Wi-Fi, video traffic and payment devices may share resources during peak periods. Distinguish channel, switching and Internet uplink load first.

Walk through the dining floor and kitchen with the actual ordering device, checking reconnection, login and application workflows.

Rack orientation, mounting height and stock levels affect coverage. Observe real scanning devices at their working locations.

Metal racks, water-containing stock and insulated cold-room doors may block or reflect signals. Record full-stock and empty-warehouse results separately.

Scanners, cameras, IoT devices and production applications have different concurrent loads. Check channels and backhaul rather than treating every wireless device as an interference source.

Test specified clients along receiving, put-away, picking and dispatch routes, recording cross-aisle transitions and application continuity.

Conditions differ at the bedside, behind the room door and at corridor corners. Acceptance testing must go beyond walking the corridor.

Fire doors, bathroom walls, metal mirror frames and room partitions may change signal paths; compare conditions inside guest rooms.

Assess video use and guest login during busy occupancy periods alongside channel capacity, uplinks and login services.

Walk from a guest room to the lift lobby and observe client transitions and guest login status. Assess coverage separately from login policies.

Use representative clients at classroom seats, rear auditorium rows and temporary event areas; an empty venue may not reflect a fully occupied one.

Floor slabs, movable partitions, stage equipment and crowds change signal paths. Validate the actual event layout and fully occupied conditions.

When many devices download or log in at once, check active load, channel reuse and the service layer rather than estimating solely from total headcount.

Use specified teaching devices between classrooms, corridors or floors to test movement, reauthentication and primary applications.

Assess balconies, courtyards and links between buildings separately. Line of sight, distance and mounting locations affect the design, and Hong Kong outdoor-use requirements must also be checked.

Trees, building corners and other objects may obstruct paths; weather effects depend on band, distance and link characteristics.

Nearby wireless networks, event crowds and uplink connections may affect capacity; outdoor sites also require measurement and channel planning.

Test client transitions along the actual walking or working area, confirming equipment protection, power and site-boundary arrangements.

New partitions, insulating glazing and equipment placement after refurbishment may change coverage; recheck regular usage locations against updated plans.

Insulation with metallic facings or coated glass may behave differently from ordinary materials. Compare conditions on site.

Switch-port schedules, PoE power and client power-saving settings can affect availability. They are not all radio interference; first check settings and logs.

When retaining older equipment or replacing clients, check bands, drivers and power-saving behaviour on the actual devices, then test movement routes.
