Enterprise WiFi & Network Design
Poor wireless coverage, network bottlenecks, and ad-hoc infrastructure decisions accumulate into real business problems — dropped video calls, slow file transfers, security gaps, and projects that fail at go-live.
With 11+ years of enterprise network and wireless experience — designing and deploying Cisco and Aruba environments across hotels, factories, campuses, warehouses, and corporate offices — I provide network design, wireless planning, and infrastructure project delivery for organizations that need it done right.
What I Do
📡 Enterprise Wireless (WLAN) Design
- RF planning and coverage design — heat mapping, capacity planning, AP placement
- Cisco and Aruba wireless architecture (controller-based and cloud-managed)
- High-density environments: hotels, conference centers, warehouses, hospitals
- Guest and staff network segmentation (VLAN, SSID isolation)
- Roaming optimization and seamless mobility
- Ekahau site survey for predictive and post-deployment validation
🏗️ Network Architecture & LAN/WAN Design
- Campus and branch network design (Core / Distribution / Access)
- VLAN design and segmentation strategy
- Routing protocol selection and configuration (OSPF, BGP, EIGRP)
- SD-WAN design and implementation
- High availability and redundancy planning
🏢 Office Build & Relocation Projects
- New office network infrastructure from scratch
- Office relocation — network cutover planning and execution
- Structured cabling coordination
- Integration with existing corporate infrastructure
☁️ Cloud-Managed Networking
- Cisco Meraki — full-stack cloud management (MX/MS/MR)
- Aruba Central — cloud management for campus and branch
- Centralized monitoring, alerting, and lifecycle management
Supported Platforms

Project Experience
- Hotel — 200+ Aruba APs, 50+ switches, 99.9% uptime, guest/staff segmentation
- Factory (dairy company) — full wired network redesign, 802.1X, zero production downtime
- Warehouse — 200+ APs, high-density coverage, dual WAN VPN redundancy
- Education campus — full Cisco Meraki deployment (MX/MS/MR/MV), cloud-managed
- Global packaging manufacturer — multi-site wireless renewal, Cisco ISE NAC integration
- German international company — Aruba Mobility Master + ClearPass, Ekahau site survey
How Projects Work
- Discovery — I review your current infrastructure, understand requirements, identify gaps
- Design — High-Level Design (HLD) and Low-Level Design (LLD) with bill of materials
- Delivery — Remote configuration + on-site coordination as needed
- Handover — Full documentation, training for your team
Typical project investment: €800 – €8,000 depending on scope and site count.
