Report Indicates Obvious Wi-Fi Conclusions

I do not understand this report: I've read Epitiro's report, which does not disclose any funding source for it, and I'm baffled. The report measures Wi-Fi speeds versus wired LAN speeds for broadband connections. Naturally, Wi-Fi speeds are lower. Wi-Fi has far more overhead than Ethernet, suffers from interference, and drops in speed the further you are from a transmitter. That's been true since 802.11b premiered in 1999.

One of the report's authors is paraphrased by the BBC as concluding, "for those who invest in good quality wi-fi equipment and position it sensibly, the effects of the speed degradation would hardly be noticed." So. Why was this report written again?

I suppose the company, which has broadband providers among its customers, wants to be sure that there's awareness that you can have higher rates of speed from very fast broadband connections by plugging in. However, with 802.11n networks and the much faster flavors of broadband available, it's unlikely most people would notice at all.

The report indicates if you're too far from an access point, you might have trouble with Skype. Well, duh. This is general background Wi-Fi knowledge. Measuring it more precisely doesn't advance the body of information about how Wi-Fi works in a home.
