LAN & WAN
Network Design
Campus LAN and enterprise WAN network design — core/distribution/access topology, SD-WAN, MPLS, VLAN architecture, QoS design and redundancy planning for offices, campuses, hospitals and industrial facilities.
What We Offer
A well-architected LAN and WAN is the invisible backbone of every modern enterprise — carrying data, voice, video and building system communications across the campus and between sites. ASDV Consultant provides professional network infrastructure design consultancy that bridges the gap between physical cabling (passive infrastructure) and the active switching/routing layer.
Our LAN designs follow the three-layer hierarchical model (core, distribution, access) or collapsed core architectures for smaller deployments. We design VLAN segmentation, redundancy (spanning tree, VSS, stacking), Quality of Service (QoS) for voice and video, Power over Ethernet (PoE/PoE+/PoE++) for IP devices, and network management and monitoring infrastructure.
WAN designs cover MPLS leased lines, SD-WAN overlay architectures, Internet VPN, dedicated dark fibre and hybrid WAN topologies — enabling secure, resilient multi-site connectivity. Our designs are vendor-informed but specification-level, enabling competitive procurement rather than pre-selecting a specific brand.

Frequently Asked Questions
A Local Area Network (LAN) connects devices within a single building or campus — from workstations to servers, printers, IP cameras and access points. A Wide Area Network (WAN) connects multiple geographically dispersed LANs — linking branch offices to headquarters or data centres over leased lines, MPLS or the internet. ASDV Consultant designs both LAN campus infrastructure and the WAN connectivity linking multiple sites.
Software-Defined WAN (SD-WAN) is a network architecture that centralises WAN management and uses software intelligence to dynamically route traffic across multiple WAN connections (MPLS, broadband internet, 4G/5G) based on application policy, link quality and cost. SD-WAN is recommended for organisations with multiple sites, high WAN bandwidth requirements or a desire to reduce MPLS costs by using broadband internet as a secondary/primary WAN transport.
IEEE 802.3af provides up to 15.4W per port (suitable for IP phones, basic cameras). 802.3at (PoE+) provides up to 30W (WiFi 6 APs, PTZ cameras, multi-port IP phones). 802.3bt (PoE++ or 4PPoE) provides up to 90W per port — required for access control systems with integrated heaters, high-performance APs, thin clients and IoT hubs. The correct PoE standard depends on the powered device requirements.
