Note: Prices reflect a 20% increase in current market rates, including labour, trunking, faceplates, and connectors based on average contractor rates in Singapore.

Recommended Cabling Based on Home Type and Size

General advice: One RJ45 point per room, two points for each primary workspace or media area (e.g. living room, office or gaming room).

Why Choose Cat 6a Over Cat 6 for Multi Storey Landed Properties?

Multi storey landed houses in Singapore typically have three to four floors. Cat 6 cables, while cheaper, have limited performance at 10Gbps beyond 55m. For a larger home, signals degrade noticeably on higher floors. Cat 6a cables ensure stable, reliable 10Gbps connections across all floors without compromise, making them a much better investment for future-proofing.

Is Cat 7 or Cat 8 Worth the Higher Cost?

Cat 7 and Cat 8 cables offer very high bandwidth and excellent shielding, but they are significantly costlier and more challenging to install. They typically exceed residential needs, being more suitable for specialized commercial or data centre environments. Cat 6a remains the best value option for most homeowners.

Pros and Cons Summary

Cat 5e

• Pros: Cheapest option, sufficient for basic internet
• Cons: Not suitable for future speeds above 1Gbps

Cat 6

• Pros: Good balance of cost and performance
• Cons: Limited range for stable 10Gbps speeds

Cat 6a (Recommended)

• Pros: Ideal for future-proofing, stable 10Gbps performance
• Cons: Slightly thicker cables, moderate cost increase

Cat 7 and Cat 8

• Pros: Highest speed and shielding available
• Cons: High cost, difficult to install, unnecessary for typical residential use

Frequently Asked Questions (FAQs)

How long do Ethernet cables typically last?

With proper installation, Ethernet cables generally last 10 to 15 years or more, emphasizing the importance of future-proofing.

Is Cat 6a noticeably faster than Cat 6?

At shorter distances, differences may be minor. However, at distances beyond 55m, Cat 6a significantly outperforms Cat 6.

Does upgrading Ethernet cables reduce latency?

No significant latency improvement is typically observed in residential settings; latency depends more on equipment quality and internet service.

Should I install Cat 8 cables at home?

Usually, no. Cat 8 is designed for ultra-high-speed short-distance scenarios like data centres and is not cost-effective for residential use.

Final Recommendations

• For HDB Flats, choose Cat 6 cables—practical and budget-friendly.
• For Condos, Cat 6 or Cat 6a provides a balanced performance.
• For Multi Storey Landed Properties, investing in Cat 6a ensures reliable, high-speed connectivity across multiple floors, future-proofing your home effectively.

Cat 6a cables provide the ideal mix of performance, reliability, and value for Singaporean homes. Investing slightly more initially offers significant long-term savings, superior speeds, and better network reliability.
