Networking and structured cabling
scope outline.

Cat6A copper plant + OFC backbone, VLAN-segregated switch stack, controller-based Wi-Fi, PoE budget design. The substrate for every other discipline above.

In scope

Horizontal Cat6A and vertical OFC design • Switch stack and VLAN architecture • PoE budget design per IEEE 802.3 class • Wi-Fi AP placement and channel plan • QoS policy across surveillance / AV / data / voice

Out of scope

Cellular DAS / in-building cellular (separate scope) • Public Wi-Fi commercial billing platform

· Documents required

Materials the consultant needs before specification starts.

  • Architectural floor plan with riser positions

  • Discipline scope from CCTV / AV / BMS for VLAN sizing

  • User-density profile per floor

· Site survey

Pre-design walk-through verifications.

  • Riser space, cable-tray availability

  • Server-room cooling capacity

  • Wall / floor material for Wi-Fi attenuation modelling

  • Power availability at each AP location

· Deployment checklist

Engineering items every install of this discipline carries.

  • Cat6A horizontal to every outlet (Wi-Fi 7 ready)

  • Dual OFC routes between MDF / IDF for ring redundancy

  • VLAN segregation: data, voice, surveillance, BMS, guest

  • PoE budget headroom ≥ 30%

  • Channel plan with co-channel interference check

· Coordination with other trades

Works owed to / from other disciplines.

  • CCTV / AV / BMS / access control: VLAN and QoS provisioning

  • Power: UPS rail per switch closet

  • Architectural: cable-tray routing and conduit sizing

· Commissioning

Measurable artefacts produced at handover.

  • Cabling certification per IS 11500 / TIA 568

  • Wi-Fi heatmap survey post-install

  • PoE budget audit per switch

  • Configuration baseline export

· Handover

What the building team takes ownership of.

  • Cabling certification report per channel

  • Switch and AP register with serial / firmware / position

  • VLAN / QoS policy documentation

  • Wi-Fi heatmap

· Risk register starter

Risks worth tracking from day zero.

  • PoE budget erosion as devices grow

  • Wi-Fi performance dropping with client-device generation shift

  • Cable damage at frequently-patched panels

· Exclusions and assumptions

What is not in scope; what we assume to be true.

  • Excludes WAN connectivity / ISP

  • Assumes building riser space is sized for the design cable count

· Where to go next

Plug the scope into the rest of the platform.
