Is More Unlicensed Spectrum the Best Path Forward?

The best approach to the future of W-Fi is better use of existing spectrum, not adding more unlicensed spectrum, according to Richard Bennett, a network engineer who contributed to the original Wi-Fi specification, 802.11n, and ultra-wideband standards. Bennett’s study, “Lessons from the History of Wi-Fi,” found that larger channels offer only “incremental improvements only at very close range”. Newer versions of Wi-Fi using existing unlicensed spectrum near the router are capable of avoiding bottlenecks in the home. However, additional spectrum used just a room away did not provide the same benefits.
