Understanding How Wireless Standards Work 0
Ever since phones started becoming miniature computers companies have been attaching the (insert number)G status into their products marketing. Starting with 2G we’re now entering the 4G era of smartphones. But what exactly is this differential anyway? Who decides it? More importantly, what does it mean?
The United Nations decides it – sort of. More specifically a UN agency called the International Telecommunications Union decides what is and what isn’t 2G, 3G, and so on. As it turns out, it’s all about speed. For example the current benchmark for a networked device to be classified as being part of the 4G collective it has to retrieve data at 400Mbit/s when the user is highly mobile in a car, and 1Gbit/s when the user is walking or stationary. The ITU also designates certain security measures that a 4G phone should have that separate it from the 3G network.
This isn’t legally binding regulation, however. It’s merely a defining guideline for the communications spectrum. That poses a problem for consumers in the United States and elsewhere who are currently shopping around for a 4G phone. Earlier this year AT&T received a lot of criticism from industry experts who claimed that the telecommunications giant was marketing a few models as being part of the 4G when they were really just running on highly modified versions of AT&T’s 3G software and network. With Sprint and HTC 4G Android phones already on shelves, it can be safely said that 4G is well on its way. But it’s important to remember that so long as not enough people raise a stink about it afterward, any mobile phone service provider can conceivably market their phones as being part of any generation they want.
That makes me wonder whether or not using the 3G-4G differential is really just a clever marketing strategy by service providers to simplify the choice for consumers bent on getting the best and newest technology. Hopefully that’s not the case and there is mostly true value to the designation. Either way, 4G is definitely here, but just make sure you exercise proper research when picking the next phone you want. Check with the ITU guidelines and ask for a demonstration of a phone’s speed in action before making a purchase. That’s the kind of thinking that gets you to the next generation.
