Here's a clear, structured comparison of UTP Cat 5e vs Cat 6, Cat 6A, Cat 7, and Cat 8, so you can understand their key differences and applications — especially relevant for high-speed networks like Wi-Fi 7 and future-ready infrastructure.

*Note: Cat 7 often uses non-standard connectors like GG45 or TERA, making compatibility with normal RJ45 equipment limited.
Key Differences Explained
1. Cat 5e (Enhanced Category 5)
- Suitable for 1 Gbps Ethernet.
- Max length 100 meters.
- Most affordable, but becoming outdated.
- Fine for basic home or office use — not recommended for future-proofing.
2. Cat 6
- Designed for 10 Gbps, but only up to 55 meters.
- Runs 2.5 or 5 Gbps comfortably over 100m.
- Ideal for Wi-Fi 6 or Wi-Fi 7 backhaul, if cable runs are within distance limits.
- Usually UTP, but can be shielded.
3. Cat 6A (Augmented)
- Handles 10 Gbps at full 100m, thanks to improved shielding and insulation.
- Higher bandwidth (500 MHz) and less crosstalk.
- Best choice for future-proofing — ideal for smart homes, buildings, and high-density PoE use.
- Slightly thicker and stiffer than Cat 6.
4. Cat 7
- Always shielded (S/FTP) for superior EMI protection.
- Often uses non-standard connectors, limiting consumer compatibility.
- Still capped at 10 Gbps, but with better shielding than Cat 6A.
- Overkill for most home setups — better in data centers.
5. Cat 8
- For data center/server room short runs.
- Up to 40 Gbps, but only 30 meters max.
- Expensive and typically not necessary for home or office unless doing heavy server/data work.
