How We Test Hardware & Calculate Speeds
At MbpsToGB, we believe you deserve data and hardware recommendations grounded in engineering reality, not recycled manufacturer marketing claims. Here is exactly how our lab benchmarks network hardware and models real-world broadband performance.
1. Our Network Hardware Testing Lab
Consumer routers, modems, and mesh systems frequently advertise theoretical PHY rates (such as "BE19000" or "AX6000") that can never be reached on real client devices. To give you trustworthy, reproducible buying guidance, our testing process evaluates hardware in a standardized, real-world residential and office environment:
Multi-Point Spatial Benchmarks
We test wireless throughput at three fixed distances: 15 feet line-of-sight (peak PHY rate test), 35 feet through two standard interior drywall partitions, and 60 feet across multiple structural obstructions to stress mesh satellite backhaul and beamforming capability.
Multi-Stream iPerf3 LAN Testing
Unlike public web speed tests that are subject to ISP throttling and server congestion, our primary wireless throughput is measured locally using multi-stream iperf3 -P 8 sessions against an isolated 2.5 Gbps / 10 Gbps wired Linux test server.
Bufferbloat & Latency Under Load
Fast download speed is useless if your ping spikes to 400ms when someone streams 4K video. We measure latency under 95% link saturation to evaluate each router's Queue Management (SQM/CAKE/FQ-CoDel) and CPU thermal stability.
Standardized Client Hardware
Our hardware test bench uses modern consumer clients including an Intel Killer BE1750 Wi-Fi 7 test rig (320 MHz channel support), Apple M-series Wi-Fi 6E laptops, and Fluke MicroScanner cable continuity and crosstalk verifiers.
2. The Calibrated 92% Real-World Overhead Standard
Most online data calculators make the fundamental mistake of using pure math: 100 Mbps ÷ 8 = 12.5 MB/s. In reality, you will never download a file at 12.5 MB/s on a 100 Mbps line.
Every byte transmitted across the internet requires packaging into TCP/IP packets with strict encapsulation layers:
- Ethernet Frame Headers: 14 bytes preamble + MAC destination/source + 4-byte CRC checksum.
- IPv4 / IPv6 Headers: 20 to 40 bytes per packet specifying routing addresses and TTL.
- TCP Overhead: 20 to 60 bytes containing sequence numbers, window scaling, and SYN/ACK flags.
- Return ACK Packets & Retransmissions: Upstream ACK packets and minor packet loss consuming active channel time.
- TLS / SSL Cryptographic Handshake: Modern encrypted web traffic adds framing overhead per TLS record.
3. Editorial Independence & Affiliate Disclosure
MbpsToGB operates with strict editorial independence:
- Zero Paid Rankings: Manufacturers cannot pay for higher ratings, preferential placement, or favorable review outcomes.
- Independent Hardware Selection: Products featured in our guides (such as our Top 7 Mesh Systems or Gigabit Routers) are selected based on verified retail popularity, market reliability, and technical merit.
- FTC Compliance: We participate in affiliate programs (including the Amazon Services LLC Associates Program). When you buy through our links, we may receive an affiliate commission at no extra cost to you. This funding allows our lab to maintain testing servers and keep our converters free for millions of users.
