IFC Tower Multi-tenant Wi-Fi and AI Wireless Operations

Challenge

Tenants had each built their own Wi-Fi, causing heavy channel interference and leaving public areas uncovered. Property management wanted one guest-and-tenant network with real-name authentication, but worried about operational load and tenant data isolation.

GSS scope of responsibility

GSS owned design, installation, authentication platform and remote managed operations for the multi-tenant Wi-Fi 6 estate. Identity-verification policy and tenant isolation requirements were set jointly by the landlord and tenants.

Solution

GSS delivered a building-wide Wi-Fi 6 multi-tenant wireless system with a unified authentication platform (SMS real-name / enterprise 802.1X / isolated tenant SSIDs), layered with AI radio self-optimisation and footfall analytics, under remote managed operations.

Background

IFC is a 52-storey Grade-A office tower housing more than 60 financial and professional-services firms, with around 9,000 people passing through on a working day. Wireless had grown tenant by tenant, so 2.4G / 5G channels interfered across floors while lift lobbies, the conference centre and the basement food court had no coverage at all. Property management wanted to build and operate one network, meet public-security real-name requirements, and guarantee complete isolation between tenants.

Solution

Wireless and authentication (traditional network business)

• Survey and design: GSS engineers ran a professional RF survey and simulation across all 52 floors, producing AP placement and channel plans; large meeting rooms and the lobby received high-density designs.
• Wi-Fi 6 multi-tenant system: 520 APs with active-active controllers; each tenant gets its own SSID + VLAN + bandwidth policy, broadcast only on the floors it leases.
• Unified authentication: guests via SMS real-name (integrated with the public-security filing interface), tenant staff via enterprise 802.1X (federated to tenants’ own AD / Azure AD), property and IoT devices via MAC + certificate.
• Installation: all AP mounting, cabling and commissioning completed outside working hours over six weeks with no tenant disruption.

AI wireless operations (AI business)

• AI radio self-optimisation: the controller continuously collects channel utilisation, neighbour interference, client RSSI and roaming events from all 520 APs; an optimisation model adjusts channel and power hourly, removing manual RF tuning.
• Experience scoring and root cause: every client session is scored across association, authentication, DHCP, DNS and throughput; low scores are automatically attributed to the AP, radio, auth server or uplink, so engineers no longer troubleshoot layer by layer.
• Footfall and space analytics: anonymised association data gives property management per-floor and public-area heat maps, dwell times and peak periods for cleaning rosters and retail leasing.
• Operations: GSS remote NOC monitoring 7×24, on-site support on demand, monthly wireless quality reports.
