WiFi 5, 6, and 7: Complete Guide for French Riviera Businesses

Launched in 2014, WiFi 5 operates exclusively on the 5 GHz band (2.4 GHz is handled by the older 802.11n standard). Its theoretical throughput reaches 3.5 Gbps, but in a real office expect 200 to 400 Mbps per device under good conditions, with a useful indoor range of about 35 metres.

Its real limit isn't speed — it's concurrent connections. Beyond about thirty active devices per access point, queuing builds up and the network becomes erratic, even with fast fibre behind it. WiFi 5 therefore remains a sound choice for a small office of fewer than ten desks, a shop in Menton or a practice in Grasse: the hardware is proven, inexpensive, and more than enough for office work, payments and occasional video calls.

WiFi 6 was designed precisely for crowded environments. Two technologies change the game: OFDMA, which splits each channel into sub-carriers so several devices are served within the same frame (less waiting, lower latency), and bidirectional MU-MIMO, which transmits to and receives from several terminals at once. Add BSS Coloring, which reduces interference between neighbouring access points — a real issue in Nice office buildings — and Target Wake Time, which extends the battery life of connected devices.

In practice: a professional WiFi 6 access point comfortably handles 50 to 100 active devices, with real-world speeds of 500 to 900 Mbps. The standard also mandates WPA3 encryption, a clear security gain for corporate networks and guest networks. It is today's best performance-to-price ratio for a hotel, training centre, restaurant or coworking space in Nice, Cannes, Antibes or Valbonne. The WiFi 6E variant adds the nearly interference-free 6 GHz band: worth considering in dense urban environments, if your device fleet supports it.

WiFi 7 pushes every limit: theoretical throughput up to 46 Gbps, 320 MHz channels on the 6 GHz band, 4096-QAM modulation, and above all Multi-Link Operation (MLO), which aggregates several bands simultaneously — a device can use 5 GHz and 6 GHz at the same time, sharply reducing latency and micro-drops.

Should you adopt it now? For most Riviera businesses, not yet: access points cost two to three times more than WiFi 6, and most smartphones, laptops and payment terminals in circulation can't exploit it. WiFi 7 is justified today for specific cases: 4K/8K video production, augmented reality, very high-density events, or a new building being cabled for the next fifteen years. For everyone else, a future-proof WiFi 6 architecture (Cat6a cabling, properly sized PoE+ switches, compatible controller) remains the most cost-effective strategy for 2026-2027: you can swap the access points later without touching the infrastructure.

45-room hotel in Cannes. The classic situation: consumer-grade WiFi 5, one box per floor, guest complaints every high season. The typical redesign: 12 ceiling-mounted WiFi 6 access points powered over PoE, seamless roaming (802.11k/v/r) between floors, a branded captive portal and a guest network isolated from the management network (PMS, cameras, payment terminals). Expected result: 150 to 250 simultaneous devices served without degradation, streaming included.

Open-space offices in Valbonne Sophia Antipolis. 60 desks, back-to-back video calls, IP telephony. Here the issue isn't coverage but density and latency: 4 well-placed WiFi 6 access points beat 8 badly tuned ones (co-channel interference). We add VLAN segmentation — production, VoIP, guests — and QoS so video calls keep priority over cloud backups. This type of project is built on our professional WiFi installation service, from the radio survey to final acceptance testing.

Whatever standard you pick, a successful deployment follows the same method. First an on-site survey: interference measurements (neighbours, DECT, Bluetooth, microwaves), building materials — the stone walls of older buildings in Nice or Antibes attenuate signal far more than drywall — and an estimate of device density per zone. Then the radio plan: the exact position of each access point, channels and power levels, Ethernet cabling and PoE power, roaming tuning for mobile usage.

Finally, network configuration: VLAN segmentation between usages (internal, guest, IoT, telephony), WPA3, scheduled updates and monitoring to catch degradations before your users do. It's this method — not the WiFi standard alone — that guarantees uniform coverage and stable performance over time. A badly placed state-of-the-art access point is still bad WiFi.

Five questions are enough to frame the decision:

• How many simultaneous devices at peak? Under 30: WiFi 5 can do the job. From 30 to 150: WiFi 6. Beyond that, or for critical usage: WiFi 6E/7.
• Which applications? Office work and payments tolerate anything; video calls, VoIP and heavy cloud usage demand low latency, so WiFi 6 minimum.
• What surface and materials? Stone, reinforced concrete and mirrors require more access points, whatever the standard.
• How long will it run? An investment planned for more than five years leans towards WiFi 6E or 7, or at least cabling ready for them.
• What security level? Public access or sensitive data: WPA3 and segmentation are non-negotiable.

A controlled budget should never sacrifice stability: an unreliable network costs more in lost time and reputation than a few well-chosen access points. If you're hesitating between two configurations, ask for a survey: measuring always costs less than replacing.
