Services
Where an outside specialist earns their fee
Engagements are short-term, project-based, and vendor-neutral. Below is the work FSI is most often brought in to do — individually, or end to end.
Wireless & RF
High-density WLAN design
Predictive design for arenas, exhibition halls, offices, lecture theatres and outdoor public space. Capacity modelling from client counts and application mix, AP and antenna selection, mounting strategy, channel and transmit-power plans.
Surveys & spectrum analysis
Passive, active and predictive surveys with Ekahau and AirMagnet. Pre-deployment validation of a design, post-deployment proof of coverage and capacity, and spectrum analysis to find the non-Wi-Fi interference nobody logged.
Optimisation & RRM tuning
Channel plans, transmit-power floors and ceilings, band steering, data-rate configuration and roam behaviour for an existing estate that under-performs at peak.
Access security — AAA, RADIUS & NAC
802.1X & onboarding design
EAP method selection (PEAP, EAP-TLS, PEAP-GTC), certificate and identity-store integration, guest and BYOD onboarding, and a policy model that maps to how the organisation actually segments users and devices.
Platform work & troubleshooting
Cisco ISE, Aruba ClearPass and FortiAuthenticator — greenfield build, migration between platforms, or deep troubleshooting of an auth path that fails intermittently and takes the help desk with it.
Enterprise & data-centre networking
Segmentation & firewall architecture
Defense-in-depth zoning, VRF segmentation, perimeter / internal / DMZ policy frameworks, and geo-redundant or virtual HA firewall clustering for resilience under attack.
Campus & DC fabric design
Routed campus and data-centre designs including MPLS-EVPN fabrics with all-active multihoming and distributed anycast gateway, plus the monitoring, telemetry and alerting to run them.
Vendor-neutral, by default
Hands-on design experience across Cisco (WLC, Catalyst, ISE, ASR/NCS), Aruba (controllers, AirWave, ClearPass), Ruckus SmartZone and R/T-series, Fortinet (FortiGate, FortiAuthenticator, FortiManager/Analyzer), Arista 7280, and service-provider consumer-Wi-Fi platforms. Recommendations follow requirements — not partner tiers.
