Moore's Law and Nielsen's Law: The Evolution of Internet Speeds
In the world of internet speeds, there are two laws that have become synonymous with the rapid evolution of technology. Moore's Law, which states that the number of transistors on a microchip doubles every two years, has been a guiding principle for the development of computer processors. However, it was Nielsen's Law that caught the attention of ISPs (Internet Service Providers) when they realized that top-end home internet speeds were increasing at a rate of 50% per year. This trend is even more remarkable than Moore's Law, and it has become a benchmark for predicting future internet speed increases.
Nielsen's Law: A More Accurate Predictor
Nielsen's Law states that top-end home internet speeds will increase by 50% each year, which is faster than the doubling rate of Moore's Law. This trend has been observed consistently since the early days of the internet and has become a reliable predictor of future internet speed increases. ISPs have used Nielsen's Law to project what speed tiers they should offer their customers in the future, with many experts predicting that 5Gigabit speeds will be the new norm.
But What About 10Gigabit Speeds?
Despite the predictions of Nielsen's Law, there are already a number of ISPs offering 10Gigabit speeds to their customers. In fact, some Network switches and cables already support 10Gigabit Ethernet, and the newest standards for sending data through cable modems also support this faster speed. So, why don't more ISPs offer 10Gigabit speeds? There are a couple of reasons.
Reasons Behind Limiting Speeds to 5Gigabits
One reason is that ISPs don't want their infrastructure to get overloaded. By limiting the top customer tier to 5Gigabits, they can ensure that capacity remains double that amount, making it easier to handle future increases in demand. Another reason is more related to demand. The average connection these days is around 200Megabits, which seems more than enough for many customers. In fact, even if you're trying to stream multiple 4K videos, those only take around 25Megs per stream, making the 200Megabit plan seem like overkill.
The Role of Upload Speeds
However, when it comes to upload speeds, things are a bit different. The average upload speed for a home connection in the US is less than 20Megabits per second, which is still far from what we need today. With smartphones that can record 4K video and more people working from home due to COVID-19, there's definitely demand for faster upload speeds. In fact, some experts predict that we might see faster upload speeds before we see super-fast download speeds.
Tested Speeds: A Glimpse of the Future
Major ISPs such as Comcast and Spectrum in the US have already successfully tested speeds at or near 10Gigabits. They've done this using a hybrid approach, where fiber carries internet traffic to a node, and then plain old coaxial cable takes over to carry that data to your house at high speed. This technology is still in its infancy, but it offers a glimpse of what's possible in the future.
The Future of Internet Speeds: 802.3ca
To take this even further, there's a new standard called 802.3ca for higher-speed fiber. The idea is to use multiple wavelengths of light, each carrying 25Gigabits per second. By combining four of these wavelengths, you can create a 100Gigabit link, which can then be sorted out with passive splitters to provide home internet connections of 25 or 50Gigabits each.
The Possibility of 16K Resolution
So, what does this mean for the future of internet speeds? With technology like 802.3ca on the horizon, it's possible that we might see even faster speeds in the not-too-distant future. And with the rise of 4K and 8K resolutions, it's only a matter of time before we start talking about internet speeds measured in terabits per second.
In conclusion, the evolution of internet speeds is an ongoing process, driven by technological advancements and shifting demands from consumers. Nielsen's Law has become a reliable predictor of future speed increases, but there are already signs that ISPs are moving towards faster speeds. With technologies like 802.3ca on the horizon, it's possible that we'll see even faster speeds in the not-too-distant future.
