A network your entire operation can depend on.
Do Link designs and deploys structured cabling, managed switching, enterprise Wi-Fi, and PoE infrastructure using brands selected for reliability, manageability, and long-term performance.
Every layer of your network, done right.
We engineer from the cable tray to the cloud management dashboard — no outsourced guesswork.
Managed Switching & Routing
Layer-2 and Layer-3 managed switches with VLAN segmentation, PoE+ for cameras and APs, link aggregation, and redundant uplinks. Cisco, TP-Link, Huawei, and Ruijie options to fit every budget and throughput requirement.
Enterprise Wi-Fi Coverage
Indoor and outdoor access points engineered for full coverage, seamless roaming, and stable user capacity. Wi-Fi 6 (802.11ax) support for high-density environments. Cloud-managed via TP-Link Omada or Aruba Central with zero-touch provisioning.
Structured Cabling
Cat6 / Cat6A UTP runs, fiber backbone, patch panels, keystone jacks, and full cable management inside 9U–42U wall-mount or standing racks. Premium-Line and Netsys passive components for certified performance.
PoE Power & Fiber Links
PoE switches and injectors deliver data and power over a single cable to IP cameras, access points, VoIP phones, and access control readers — eliminating separate power runs and simplifying installation on every floor.
The hardware we deploy at every layer.
Managed Switch
L2 / L3 managed switches with VLAN, link aggregation, and PoE+ for cameras, APs, and IP phones. 8 / 16 / 24 / 48 port options.
- 8–48 Gigabit ports
- PoE+ / PoE++ output
- VLAN & QoS
- Cloud / CLI managed
Wireless Access Point

Rack & Cabling
9U–42U wall-mount or floor-standing racks with patch panels, cable managers, and Cat6 / Cat6A / fiber runs — certified and labelled.
- 9U / 12U / 27U / 42U
- Cat6 / Cat6A / Fiber
- Patch panels & PDU
- Cable testing report
PoE & Fiber Modules
PoE injectors, SFP transceivers, fiber media converters, and patch leads. Power and data over a single cable to every endpoint.
- 30 W / 60 W / 90 W PoE
- SFP / SFP+ modules
- Fiber media converters
- Surge protected
Good network design pays for itself on day one.
A poorly planned network creates downtime, dead zones, and security gaps. A properly engineered one just works — for cameras, Wi-Fi, IP phones, and everything else.
Reliable Uptime
Redundant links, managed switches with spanning tree, and proper rack wiring mean no single point of failure brings down your cameras or operations.
Scalable Architecture
Switch stacking, cloud-managed APs, and modular rack design let you add cameras, users, or floors without replacing the core infrastructure.
Unified Integration
One LAN serves CCTV NVRs, access control panels, IP intercoms, VoIP phones, and office devices — all segmented by VLAN for security and performance.
Proven brands for every network tier.
Cisco
Enterprise-grade switches and SD-WAN routers for mission-critical environments. The global reliability benchmark for uptime and security.
