Structured Data Cabling for Homes & Businesses

In 2026, reliable network connectivity isn't optional — it's essential. Whether you're working from home, streaming 4K on multiple devices, or running a business, your wired network infrastructure determines the quality of your connection. Wi-Fi gets the headlines, but a properly cabled network is the backbone that makes everything work.

Randwick Electrical designs and installs structured data cabling for residential and commercial properties across Sydney's Eastern Suburbs. We handle everything from single data point additions to full network builds with rack-mounted patch panels and managed switches.

Our Data & Communications Services

  • Cat6 and Cat6A data cabling — standard for residential and commercial installations. Cat6 supports up to 10Gbps over short runs; Cat6A supports 10Gbps at full 100m distance. Future-proof cabling that will outlast any current technology
  • TV antenna and point installation — digital TV antenna installation, additional TV points throughout the home, and signal distribution via coaxial or over-Cat6 distribution
  • Home network setup — structured cabling from a central point (comms cabinet or patch panel) to data points throughout the house. Ideal for home offices, entertainment systems, and smart home devices
  • NBN connection and internal cabling — ensure your NBN connection is properly distributed throughout your home or office. Many installations only include one data point — we extend it everywhere you need it
  • Commercial network cabling — full structured cabling for offices, retail, and commercial spaces. Patch panels, cable management, testing and certification to Australian standards
  • Wi-Fi access point cabling — hardwired Cat6 runs to ceiling-mounted Wi-Fi access point locations. The best way to get reliable whole-home or whole-office wireless coverage
  • CCTV camera cabling — Cat6 runs for IP cameras with PoE (Power over Ethernet) support, eliminating the need for separate power supplies at each camera location

Why Wired Beats Wireless

Wi-Fi is convenient, but wired connections deliver consistent speed, lower latency, and zero interference. For devices that don't move — desktops, smart TVs, gaming consoles, NAS storage, security cameras — wired is always the better choice.

And here's the thing: the best wireless networks are built on wired infrastructure. Ceiling-mounted Wi-Fi access points connected via Cat6 cable deliver dramatically better coverage than a single router in the corner of your house.

Frequently Asked Questions

What's the difference between Cat5e, Cat6, and Cat6A?
Cat5e supports 1Gbps, Cat6 supports 10Gbps over short runs (55m), and Cat6A supports 10Gbps over a full 100m run. We recommend Cat6 minimum for residential and Cat6A for commercial installations. The cost difference is minimal but the future-proofing is significant.
Can you run data cables in an existing home without major disruption?
Yes. We use a combination of ceiling cavity runs, wall fishing, and discrete surface-mounted conduit where needed. In most cases we can add data points with minimal disruption to walls and ceilings.
How many data points do I need in my home?
As a minimum: one in each room where you have a TV, gaming console, or desktop computer, plus one per home office workstation. We also recommend runs to locations where you'd mount Wi-Fi access points (typically hallway ceiling, central location).
Do you test and certify data cabling?
Yes. All data cable runs are tested with professional Fluke testing equipment to verify continuity, wire mapping, and performance. Commercial installations include full test certification reports.
