Optimising WiFi Coverage in Nice, Cannes and Antibes (2025 Guide)

Riviera buildings stack up radio obstacles: 50 cm stone walls in the old buildings of Nice and Antibes (3 to 5 times the attenuation of drywall), reinforced concrete slabs between floors, metallised verandas, mirrors and coated glazing that reflect signal. Add outdoor usage — terraces, pools, terraced gardens — and, in dense urban areas, channel saturation from neighbouring networks.

The consequence: generic recipes ("add a repeater") often fail here. Reliable coverage is designed from real on-site measurements, not floor area. That's the whole point of the 4-step method below.

Everything starts with a heatmap: we walk the site with a measurement tool recording, room by room and outdoor zone by outdoor zone, signal strength (RSSI), signal-to-noise ratio, interference and real throughput. We overlay the building materials (stone, concrete, glass) and an inventory of usage: how many devices per zone, which applications (video calls, streaming, smart home, CCTV), which peak times.

The deliverable is a map of dead and weak zones with their causes identified. It determines how many access points are needed and where — and avoids the two classic mistakes: under-sizing (persistent dead zones) or over-sizing (interference between too many APs, wasted budget).

The radio plan turns the survey into architecture. The first structural choice: mesh or wired backbone.

Criterion	Mesh (radio backhaul)	Wired (Ethernet + PoE)
Throughput	Reduced at every radio hop	Full speed at every AP
Reliability	Sensitive to interference	Maximum
Works required	None	Cable runs
Ideal case	No renovation possible, moderate needs	Intensive use, large area, business

Our practical rule: wired wherever possible, mesh where cable can't go. PoE (Power over Ethernet) simplifies everything: one cable per AP for data and power, clean ceiling mounting, remote restart from the switch. Outdoors — terraces, pools, gardens — we specify IP65 APs, waterproof and resistant to salt air, with UV-protected cable runs. Finally, the plan sets each AP's channels and power so they complement rather than jam each other. Where justified, this plan fits into a broader network overhaul — structured cabling, patch cabinet, VLANs — described on our IT network installation page.

Installation follows the plan, not the other way round: every AP at its measured location, ceiling-mounted or high and unobstructed, never in a cupboard or behind furniture. Cabling (preferably Cat6a) is tested and certified before connection, the PoE switch sized with headroom.

Configuration: a single network name (SSID) across the site with roaming enabled (802.11k/v/r) to move between APs without drops — essential for WiFi telephony and mobile video calls; VLAN segmentation if the site hosts the public or sensitive equipment (detailed in our guest WiFi guide); power tuned AP by AP — the "everything at max" reflex creates zones where devices cling to a distant AP instead of switching to the nearest.

An installation isn't finished when "it works" but when it's measured. Acceptance testing repeats the initial mapping at the same points: up and down speeds, latency, roaming stability on the move, load behaviour with the target device count. The before/after figures are part of the report handed to the client.

Then coverage has to be maintained: remote monitoring (alerts for an offline AP or degradation), scheduled firmware updates, and channel re-tuning when the radio environment changes — one powerful new neighbouring network can degrade a perfect installation. For business premises, a maintenance contract keeps a WiFi incident from becoming a customer incident. The whole service — survey to maintenance — is detailed on our professional WiFi installation page.

This guide sets out the general method. Depending on your situation, two companions:

• Your WiFi is misbehaving today (slowness, drops) and you want a diagnosis before investing: follow the decision tree in our article WiFi problems: causes and solutions.
• You're equipping a villa or large home (floors, garden, pool, outbuildings): the concrete, numbers-based cases — APs per surface area, outdoor coverage — are in our article weak or absent WiFi in your property.

For a business project (hotel, offices, shop), the choice of WiFi standard itself — WiFi 5, 6 or 7 — is covered in our WiFi standards comparison.
