Case Studies — Real Results for Real Clients
Our case studies show how Mainframe Systems GH approaches complex IT infrastructure challenges — and the measurable outcomes we deliver.
Case Study 1: Complete Network Overhaul for a Growing SME
Client: Professional services firm, 85 employees, Accra CBD
Challenge: The client’s network had grown organically over 10 years with no structure. Frequent outages, poor Wi-Fi coverage, and outdated hardware were costing the business hours of productivity daily.
Solution: Mainframe Systems conducted a full network audit, then designed and implemented a complete structured cabling refresh (Cat6A throughout), new enterprise-grade switching infrastructure, a centralised wireless network with 12 access points, and a VoIP system to replace aging PSTN lines.
Result: Network downtime fell from an average of 8 hours/month to under 15 minutes. VoIP cut phone costs by 55%. Employee satisfaction with IT improved dramatically.
Case Study 2: Multi-Site CCTV & Access Control Deployment
Client: Retail chain with 4 locations across Greater Accra
Challenge: The client had no standardised security system. Each branch had different, aging CCTV equipment with no central oversight, making it impossible to monitor incidents centrally.
Solution: Mainframe Systems designed a unified IP CCTV system with high-definition cameras at all 4 sites, IP-based access control at staff entry points, and a central monitoring station at headquarters that provides live and recorded feeds from all locations.
Result: Stock shrinkage reduced by 45% within 6 months. Management gained real-time visibility across all branches. Insurance premium reduced due to improved security posture.
Case Study 3: Hospital Network & Security Infrastructure
Client: Private polyclinic, 3 floors, 40 consulting rooms
Challenge: A new wing was being added to an existing facility. The client needed structured cabling for networking and telephony, CCTV for patient safety and asset protection, and biometric access control for pharmacy and records rooms.
Solution: We worked alongside the construction contractor from the early stages to embed conduit runs before walls were plastered, minimising surface-mounted cabling. We installed Cat6 structured cabling throughout, 24 IP cameras, biometric access on 6 restricted areas, and a VoIP system with a nurse-call integration capability.
Result: Seamless installation with minimal disruption to ongoing patient care. The client was able to connect their patient management system site-wide from day one of the new wing’s opening.
Case Study 4: Campus Wi-Fi for an International School
Client: International school, 6 buildings, 600+ students and staff
Challenge: The school was running a consumer-grade Wi-Fi network that was overwhelmed by the number of devices. Students and teachers experienced constant disconnections during lessons, undermining the school’s digital learning programme.
Solution: Mainframe Systems designed and deployed an enterprise Ubiquiti UniFi wireless network across all 6 buildings — 18 access points, a centralised controller, and a network segmentation strategy that separated student, staff, and IoT traffic.
Result: Stable, high-speed Wi-Fi for 500+ concurrent devices. The digital learning programme is now fully operational. The school reports zero Wi-Fi-related complaints since deployment.
