Create detailed documentation of logical and physical network layouts, diagrams, and asset inventory.
Establish network policies covering QoS, bandwidth allocation, access control, and routing protocols.
Define and enforce wireless spectrum allocation policies.
Design and implement the wireless communication system, including site selection, radio propagation analysis, and antenna placement.
Specify wireless standards and protocols (Wi‑Fi, LTE, 5G, or proprietary.
Plan and oversee fiber optic network deployment for high‑speed backhaul.
Ensure fiber installations meet signal integrity specifications and minimize latency.
Coordinate with civil engineers and contractors for fiber installation, splicing, and testing.
Procure and oversee installation of routers, switches, access points, base stations, and controllers.
Configure equipment for dynamic routing, multicast, and VLANs.
Develop maintenance plans and monitor hardware lifecycle for timely upgrades.
Implement cybersecurity measures such as firewalls, IDS/IPS, and endpoint protection.
Conduct vulnerability assessments and ensure compliance with industry standards (NIST, CISA, ISO/IEC 27001).
