Network Speed Calculator
Understand how cable MHz ratings translate to real-world Gbps speeds — and how much bandwidth your applications actually need.
Cable Category Comparison
| Cable Type | Bandwidth (MHz) | Max Speed | Max Distance | Best For | CT Price |
|---|---|---|---|---|---|
| Cat5e | 100 MHz | 1 Gbps | 328 ft (100m) | Basic office, VoIP, IP cameras | From $89/1000ft |
| Cat6 | 250 MHz | 1 Gbps (10G @ 55m) | 328 ft (100m) | Office networks, PoE devices | From $2.29 |
| Cat6 Enhanced ⭐ | 550 MHz | 10 Gbps (full 100m) | 328 ft (100m) | Our Cat6 — best value for 10G | From $2.29 |
| Cat6A | 500 MHz | 10 Gbps | 328 ft (100m) | Enterprise, hospitals, PoE++ | View |
| Cat8 🚀 | 2000 MHz | 25/40 Gbps | 98 ft (30m) | Data centers, servers, NAS | From $3.30 |
⭐ Why Our Cat6 at 550 MHz is the Best Value
Standard Cat6 is rated at 250 MHz and supports 10 Gbps only up to 55 meters. Our Cat6 Enhanced is rated at 550 MHz, which means it supports 10 Gbps at the full 100-meter distance — the same performance as Cat6A at a fraction of the cost. For most office, warehouse, and light commercial installations, there's no reason to pay more for Cat6A when our enhanced Cat6 delivers the same 10G performance.
How Much Speed Do You Actually Need?

| Email & web browsing | 1-10 Mbps | 5 Mbps | Cat5e | Cat6 |
| VoIP phone system | 100 Kbps-1 Mbps | 100 Kbps | Cat5e | Cat6 (PoE) |
| Netflix / YouTube HD streaming | 5-25 Mbps | 25 Mbps (4K) | Cat5e | Cat6 |
| Zoom / Teams video conferencing | 3-8 Mbps | 8 Mbps | Cat5e | Cat6 |
| Online gaming | 25-50 Mbps | 50 Mbps | Cat6 | Cat6 Enhanced |
| IP security cameras (4K) | 15-30 Mbps | 30 Mbps | Cat5e (PoE) | Cat6 (PoE+) |
| Small office (10-25 devices) | 100-500 Mbps | 20 Mbps avg | Cat6 | Cat6 Enhanced 550MHz |
| NAS / file server backup | 1-10 Gbps | 10 Gbps | Cat6 Enhanced | Cat8 2000MHz |
| Data center / server room | 10-40 Gbps | 25-40 Gbps | Cat8 | Cat8 S/FTP |
| Enterprise backbone | 40-100 Gbps | 100 Gbps | Fiber optic | View fiber |
Understanding MHz vs Gbps
MHz (Megahertz) measures the cable's bandwidth — how many signal cycles per second the cable can carry. Think of it like the width of a highway. More lanes (higher MHz) = more cars (data) at the same time.
Gbps (Gigabits per second) measures actual data throughput — how fast files transfer. This depends on both the cable bandwidth AND the network equipment (switches, routers, NICs).
The relationship: Higher MHz cables can carry more data per second. But the cable is only one part of the equation — your switch and NIC must also support the target speed. A Cat8 cable won't give you 40 Gbps if your switch only supports 1 Gbps.
Rule of thumb: For most applications, Cat6 Enhanced at 550 MHz is the sweet spot — it delivers 10 Gbps performance at Cat6 pricing. Only upgrade to Cat8 if you're running server-to-server connections, NAS storage, or data center infrastructure.
Quick Reference: What 1 Gbps Actually Means
| Task | At 1 Gbps (Cat6) | At 10 Gbps (Cat6 Enhanced) | At 40 Gbps (Cat8) |
|---|---|---|---|
| Download a 4K movie (20 GB) | 2 min 40 sec | 16 seconds | 4 seconds |
| Backup 1 TB hard drive | 2 hours 13 min | 13 min 20 sec | 3 min 20 sec |
| Simultaneous 4K streams | ~40 streams | ~400 streams | ~1,600 streams |
| VoIP calls simultaneously | ~10,000 | ~100,000 | ~400,000 |
