Hi, this is Wayne again with a topic “Your Internet Is About To Get FASTER – 2.5 Gbps explained”.
Consumer Ethernet has pretty much followed the rule of each generation having ten times the maximum speed of the previous one. However, the game is changing. There are actually some quarter and half measures in the works. Yes, my friends, that’s right. You’Re gon na be seeing two point. Five gigabit and five gigabit ethernet devices popping up all over the place, but why to answer we spoke to Ben hacker and Ben Benson over at Intel and we’d like to thank them for their contributions to this episode, as internet speeds get faster. It’S becoming clear that we’re gon na need something that is faster than the gigabit ethernet, that’s supported by lots of our home, modems and routers. Even if you don’t have fibre to the home. New versions of the DOCSIS cable internet standard can support speeds beyond one gigabit per second.
In fact, two gigabit connections are becoming common in tech mecca’s, like south korea and japan, which is all fine and good. But why bother with this tweener stuff when you can go out and buy a 10 gigabit network card and ten gigabit switch today? Well, the issue is that the 10 gigabit standard doesn’t work very well over most of the existing Ethernet cabling, that’s out there. So if you go out and buy a theoretical cable modem with a 10 gig port on the back of it, chances are that you’re gon na end up needing to change out every network cable in your house in order to get the full benefit of it. And in commercial installations, this problem is much worse. You see many buildings have been pre-wired with ethernet jacks in the walls that used the older cat 5e cable standard, which was designed to handle up to 1 gigabit per second over a distance of 100 meters and for a long time that was just fine but 10 Gigabit Ethernet requires a newer cable called cat 6 to go 50 meters and an even higher end, cable called cat 6a with the a4 augmented to do the full hundred meters. The reason that CAF IV can’t carry a 10 gigabit signal effectively over those distances is that it doesn’t have as much protection against interference and crosstalk.
So what this means is that getting 10 gigabit to work in many places would mean ripping the old cables out of the wall and putting in new ones, and that is alongside all of the equipment in the networking room and all of the client pcs. That is a tough, triple whammy to the old corporate pocketbook, so the powers that be are instead introducing a two and a half Gigabit Ethernet solution, because it turns out that a cat5e cable that was built to spec can actually handle a two and a half gigabit Per second signal, just fine over a hundred meters and even a five gigabit per second signal, will usually work. The holdup was just that the industry doesn’t like to bother rolling out a new spec for less than ten times the previous speed, because they typically view it. As not being worth the effort it takes, but given how excessive the ten gigabit speed is for general consumers and the fact that ten gigabit equipment is still a lot more expensive, the industry has finally developed an interest in being able to sell faster equipment at a Price that consumers can actually handle so faster ethernet speeds then are gon na have immediate benefits for enthusiasts and prosumers, who want the additional bandwidth for things like transferring files between pcs and network attached storage or running home media servers. As for the regular consumer, well, the benefits today might actually be limited, but two and a half or five gigabit, ethernet jacks rolling out in computers, network adapters and modems over the coming years means that our underlying infrastructure is going to be ready for future advancements. Like 8k streaming video to multiple household members and other amazing technology, that makes it so we just don’t actually have to talk to each other anymore.
Speaking of talking to your each other, I want to talk to you about fresh books. First books is the small business accounting software that’s built for freelancers and small business owners. It’S a simple way to be more productive, more organized and to get paid faster with fresh books. You can create and send professional-looking invoices in less than the time that it takes for me to read this sponsor spot.
You can set up online payments with just a couple of clicks and get paid up to four days faster. You can see when your client has seen your invoice to put an end to the guessing games. You can track your hour, so you can track your expenses and you can do it for free for 30 days, just go to FreshBooks, comm, slash tech quickie and enter tech quickie in the.
