As someone who's banged the drum as loud as anyone in support of setting a high bar for our national bandwidth goals, this next statement is going to come as a bit of a surprise: I think we're focusing too much attention on bandwidth.
Now, I'm not trying to suggest that bandwidth is unimportant. Instead the argument I want to make is that bandwidth isn't the only thing that matters, and that by pursuing policies that prioritize bandwidth over everything else we're going to take our country down a less than optimal path to our broadband-enabled future.
The first part of this argument is fairly straight forward. When it comes to broadband performance, bandwidth is only one factor. For example, for real-time applications like VoIP latency can be more important than bandwidth. Another factor, which bandwidth admittedly plays a role in but isn't the sole determinant of, is reliability. Then there are more technical metrics like jitter that can affect broadband performance.
What this all means is that for America to have a world-class broadband infrastructure we need more than just high capacity networks; we need high performance broadband networks. We need broadband that delivers high capacity, low latency, low jitter, high reliability connectivity, not just broadband that delivers fat pipes with poor performance.
In terms of real-world impact, the reason for this is simple. If all we had was high bandwidth but poor performance broadband then sure, we might be able to download movies fast but we won't be able to utilize the oncoming wave of real-time apps that require high performance broadband networks.
This then brings us to the overarching problem with basing the debate around America's broadband needs solely on bandwidth.
If all we focus on is bandwidth, then we allow broadband providers to obfuscate the clear differences between the overall performance of different broadband technologies.
For example, the FCC has set the bar for defining broadband at 4Mbps down and 1Mbps up. So now any technology that claims to deliver that much bandwidth can be eligible for government subsidies. Yet as we just covered, bandwidth is not the only determinant of performance!
This line of thinking is extremely important to consider for anyone who's a supporter of fiber. For the longest time we've couched arguments supporting fiber in terms of bandwidth. We cite how fiber can deliver future-proof bandwidth as the primary reason America should get behind it. Yet I'm not sure if that's a winning argument.
First off, by focusing on a single attribute of fiber it makes it much easier for other technologies to claim parity. Like this recent article that shows how cable networks should be able to deliver 1Gbps in the next decade. Or the constant promises from wireless and satellite providers that some day they too will be able to deliver bandwidth equivalent to that of wireline. Because of these I don't think we can win on bandwidth alone.
Secondly, by just talking about bandwidth we're leaving some of the strongest arguments in support of fiber off the table, namely that fiber is the most high performance broadband technology out there. What we need to be doing is showing people how there's a new wave of next gen apps on the horizon that are going to require not just high capacity but high performance broadband networks in order to operate optimally.
By taking this more holistic approach to talking about America's broadband needs and tying those needs to specific applications, like the delivery of high quality two-way video, we can put a finer point on the argument for why fiber should be the technology of choice to build America's broadband future. We can show in clear, undeniable terms why wireless technologies will never match the performance of fiber and what they means in terms of usability of the Internet.
This doesn't mean we should forego talking about bandwidth as it still is arguably the most important characteristic to consider for broadband networks. But let's not limit ourselves to only talking about bandwidth. Let's make sure that everyone knows the importance of taking a more holistic approach to understanding the importance of America having a broadband infrastructure that's not just high bandwidth but also high performance.
Only then will we have a chance to make sure that Americans are able to have access to the connectivity necessary to take advantage of all that the Internet will make possible in the 21st century.
