District WiFi and analytics planner
Size the access points a Hudson Yards style district needs, then see how many visitors become opted-in marketing profiles each month.
Offices and homes run their own networks, so a mixed-use district usually lights only its retail, dining and public spaces.
Unticked, GDPR and CCPA compliant consent boxes.
Use your own figure, for example annual email revenue per subscriber.
The Hudson Yards pattern: Cisco controllers and Spaces location data, carrier fibre from AT&T, Purple on top for the portal and analytics.

Plan summary
Large venue guest WiFi and analytics plan Venue type: Mixed-use urban district (for example Hudson Yards) Built area: 18,000,000 sq ft (1,672,254 m2), 10% covered by guest WiFi Access points: about 515 (coverage 515, capacity 38) Peak concurrent WiFi clients: 1,875 Wireless platform: Cisco Catalyst 9800 and Cisco Spaces with AT&T backhaul (WiFi 6/6E, controller cluster) Monthly visits: 1,500,000; WiFi connections: 375,000 (25%) New opted-in profiles: 121,875 a month, 1,462,500 a year (50% opt-in) Illustrative annual value at $2 per profile: $2,925,000 Value drivers: Cross-marketing between retail and dining tenants; Plaza and public realm footfall heatmaps; Sponsored captive portal placements; Resident, worker and visitor split
How the numbers are worked out
- •Access points are the larger of a coverage count (covered area divided by square feet per AP for this venue type) and a capacity count (peak clients divided by 50). A predictive survey will refine both.
- •Peak clients are daily visitors multiplied by the share on site at the busiest moment (15% for this venue type) and by the WiFi connection rate.
- •New profiles count first-time connections only: returning visitors are removed before the opt-in rate is applied, so repeat visits are not counted as new records.
- •Visitor numbers and the value per profile are your inputs, not published Hudson Yards figures.
Purple runs the captive portal and analytics on Cisco Meraki, HPE Aruba, Ruckus, Juniper Mist, Ubiquiti UniFi, Cambium, Extreme and Fortinet networks.
Hudson Yards is North America's largest private real estate development, spanning 28 acres and 18 million square feet on Manhattan's West Side in New York City. Built above an active rail yard, this mixed-use development comprises more than 100 retail shops, Michelin-starred restaurants, corporate headquarters, luxury residences, public gardens, and cultural venues.
To power seamless guest connectivity and extract physical visitor intelligence across this immense urban landscape, master developer Related Companies partnered with Purple, Cisco Systems, and AT&T. By deploying Purple's cloud-managed guest WiFi and location analytics platform across more than 2,000 Cisco enterprise access points and AT&T carrier fiber backhaul, Hudson Yards turned passive foot traffic into actionable first-party CRM profiles and revenue-driving tenant engagement.
The engineering challenge: high-density mixed-use wireless
Operating a unified wireless infrastructure across 18 million square feet presented distinct architectural hurdles:
- Extreme device density: Tens of thousands of daily office workers, local residents, international tourists, and retail shoppers simultaneously competing for RF airtime across indoor retail concourses and open-air public plazas.
- Network segmentation and security: Strict Layer 2 and Layer 3 isolation required to separate unauthenticated public guest devices from building management systems (BMS), tenant point-of-sale terminals, and corporate enterprise LANs.
- Carrier-grade offload and backhaul: Seamless coordination with AT&T cellular networks to offload mobile data traffic and ensure high-throughput public internet breakout.
- Unified visitor intelligence: The need for a single, hardware-agnostic analytics engine capable of ingesting real-time location telemetry to quantify cross-shopping behavior, dwell times, and plaza footfall heatmaps.
The solution: Cisco infrastructure, AT&T backhaul, and Purple cloud intelligence
Related Companies selected an integrated networking and software stack to address the scale of the district:
- Cisco enterprise access points: Over 2,000 Cisco Catalyst access points deployed across retail floors, commercial lobbies, and outdoor public spaces, centrally orchestrated through high-availability Cisco Wireless LAN Controller (WLC) clusters.
- AT&T multi-gigabit carrier backhaul: Dedicated fiber transport providing redundant multi-gigabit throughput to eliminate bandwidth bottlenecks during major public events and holiday shopping surges.
- Purple cloud RADIUS and captive portal: A responsive, custom-branded captive portal rendered instantly on connecting devices, supporting cell phone number SMS verification, email registration, and social login with unbundled CCPA/CPRA consent checkboxes.
- Cisco Spaces telemetry integration: Real-time streaming API integration syncing wireless probe requests and location trilateration data into Purple Analytics for zone-level occupancy and dwell time analysis.
Commercial results: 300,000 verified CRM profiles in 5 months
Within the first five months of deployment, Hudson Yards recorded measurable operational and commercial milestones:
- 500,000+ guest connections: Over half a million visitors successfully authenticated onto the branded guest network across indoor and outdoor zones.
- 300,000 new CRM profiles: Captured 300,000 verified customer records with full marketing permissions, achieving a 60% opt-in conversion rate.
- Monetized sponsorship splash pages: Delivered dynamic HTML splash screens promoting cultural exhibits, seasonal shopping discounts, and upcoming performances at The Shed cultural center.
- Optimized retail tenant placement: Analyzed hourly footfall velocity and pedestrian circulation paths to provide retail leasing teams with empirical footfall data for commercial negotiations.
Privacy, data governance, and ISO 27001 compliance
Managing visitor data across a landmark destination requires rigorous data protection standards. Purple operates under certified ISO 27001 information security management and B Corp governance principles. Visitor data collected through the Hudson Yards captive portal is encrypted at rest and in transit, never sold to third-party data brokers, and managed through automated data retention schedules with self-service Consumer Privacy Request workflows.
Architectural blueprint for smart districts and mixed-use real estate
The Hudson Yards deployment demonstrates that enterprise guest WiFi is no longer an operational expense, but a fundamental digital asset for commercial real estate developers. By pairing carrier-grade wireless hardware with cloud analytics, venue operators bridge the gap between physical property management and modern digital marketing.
