From Pilot Wi-Fi to Nationwide Enterprise Wireless Backbone

Challenge

• Enterprise Wi-Fi in manufacturing environments was still experimental in 2013.
• Fragmented and inconsistent wireless coverage across facilities.
• No centralized management or visibility.
• Limited mobility enablement in corporate environments.
• No validated blueprint for Wi-Fi adoption on factory floors.
• Uncertainty around scalability and controller performance for multi-site expansion.
• Strategic uncertainty: whether wireless infrastructure could evolve from a convenience layer into a mission-critical backbone.

Solution

• Vinay Enterprises partnered with Aruba Networks to introduce a centralized wireless architecture designed for long-term scalability.
• Initial Pilot (2013):
  • 40 × Aruba AP-105 Access Points
  • 1 × Aruba 3400 Mobility Controller
  • Centralized management architecture
• Pilot objective:
  • Validate coverage stability
  • Test roaming performance
  • Assess controller scalability
• Architectural decisions:
  • Controller-based centralized architecture
  • MPLS-backed multi-site connectivity
  • Policy standardization across locations
  • Built-in redundancy and failover design
  • Lifecycle-driven hardware evolution

Implementation

• Step 1 – Pilot Validation

  • Site survey and RF heatmap analysis
  • Central controller deployment
  • Coverage and roaming optimization
  • Performance benchmarking under production conditions

• Step 2 – Multi-Site Expansion

  • Gradual AP rollout across plants and corporate offices
  • MPLS integration for controller centralization
  • Policy standardization across locations
  • Central visibility and access control implementation

• Step 3 – Controller Evolution & Redundancy

  • Controller progression:
    • Aruba 3400 (initial deployment)
    • Aruba 7030 (clustered architecture)
    • Aruba 7210
    • Aruba 9240 Mobility Controller (Silver License, up to 1000 AP capacity)
  • Dual physical controller sites:
    • Sathej Plant: 2 × clustered 7030
    • GIFT City Data Center: 2 × standalone 7030 + 7210
  • Master redundancy via Aruba 9240
  • Sub-10 second failover during controller outage
  • MPLS connectivity linking Ahmedabad and Bangalore sites

• Step 4 – Generational Access Point Upgrades

  • AP lifecycle evolution:
    • AP-105 → AP-205 → AP-305 → AP-505
  • Proactive upgrades ensuring firmware compatibility, controller alignment, and future capacity readiness

• Step 5 – OS & Firmware Modernization

  • Migration from Aruba EOS 6 to EOS 8
  • Zero production disruption
  • Policy continuity and configuration integrity maintained
