01
Client Profile & Background
A large private university in Tangerang, Indonesia, with over 15,000 students and 2,000 staff across a 50-hectare campus. The institution operates multiple faculties, research centers, libraries, dormitories, and administrative buildings. The existing wireless network, deployed in 2016, comprised consumer-grade access points from a generic brand, which were never designed for enterprise-scale usage. The university relied heavily on digital learning platforms, online examinations, and campus-wide IoT devices for smart building management, making a robust WiFi infrastructure critical for daily operations.
The university's IT department managed the network in a decentralized manner, with each building having its own subnet and minimal coordination. This led to inconsistent coverage, frequent disconnections during peak hours, and security gaps that exposed sensitive student and research data. As the university expanded its digital initiatives, including a new e-sports arena and a smart library, the need for a comprehensive WiFi upgrade became urgent. The leadership recognized that a modern, high-density wireless network was not just an operational necessity but a competitive advantage in attracting top talent and enabling innovative teaching methods.

Technical Challenge
The primary challenge was the network's inability to handle high-density environments. During peak hours, over 5,000 concurrent users would connect to the WiFi, causing severe congestion and packet loss. The average throughput per user dropped below 2 Mbps, making video streaming and online exams impossible. Additionally, the legacy access points (APs) only supported 802.11n, with a maximum theoretical speed of 300 Mbps per AP, which was grossly insufficient for modern applications. Coverage gaps existed in key areas like the auditorium, sports complex, and outdoor plazas, where signal strength was below -75 dBm.
Security was another major concern. The network had no centralized authentication or encryption, leaving it vulnerable to rogue APs and man-in-the-middle attacks. The university had experienced two security incidents in the past year, including a data breach that exposed 10,000 student records. Furthermore, the lack of network segmentation allowed malware to spread rapidly across the campus. The IT team spent over 20 hours per week troubleshooting connectivity issues, and the average time to resolve a ticket was 48 hours. The outdated infrastructure also hindered the deployment of IoT devices for smart lighting and HVAC systems, as the network could not support the required device density.
03
Implemented Solution
Intilogy designed a complete WiFi upgrade using a three-tier architecture with Cisco Catalyst 9800 Series Wireless Controllers for centralized management, Ruijie RG-AP880-I access points (Wi-Fi 6, 4x4 MIMO) for high-density coverage, and Fortinet FortiGate 600F firewalls for integrated security. The deployment included 450 APs strategically placed to cover all indoor and outdoor areas, with a focus on high-traffic zones like lecture halls and libraries. Each AP supports up to 512 concurrent users, with an aggregate throughput of 5 Gbps, ensuring smooth performance even during peak loads.
The network was segmented into multiple SSIDs using 802.1X authentication with RADIUS servers, providing role-based access for students, faculty, and guests. For IoT devices, a separate SSID with WPA2-Enterprise was implemented, isolated from the main network. The Enterprise WiFi solution also included Cisco DNA Center for AI-driven analytics and automated troubleshooting, reducing mean time to resolution (MTTR) by 80%. Additionally, the university deployed a Hybrid Cloud management platform for centralized monitoring and reporting. The entire project was completed within 3 months, with minimal disruption to campus activities.
04
Results & ROI
Post-upgrade, the campus achieved 99.9% uptime with zero connectivity drops during peak hours. Average throughput per user increased from 2 Mbps to 150 Mbps, enabling seamless 4K video streaming, real-time collaboration, and online examinations. The number of supported concurrent users rose to 8,000 without degradation, exceeding the initial requirement. Coverage improved to -65 dBm or better across 95% of the campus, eliminating dead zones.
Security incidents dropped to zero in the first year, thanks to the Cyber Security features integrated into the Fortinet firewalls and Cisco ISE. The IT team's troubleshooting time decreased from 20 hours per week to 4 hours, and ticket resolution time fell from 48 hours to 4 hours. The university also saw a 30% reduction in energy costs due to smart IoT integration, which was now possible with the reliable network. The total cost of ownership (TCO) was reduced by 25% compared to the previous setup, as the new APs consumed less power and required fewer replacements. The ROI was realized within 18 months, driven by increased operational efficiency and enhanced user satisfaction.
