So head with me down the rabbit hole that is 5G as I try to explain what the heck is going on. 1G, 2G, 3G, 4G, 5G The G in 5G means it's a generation of wireless technology. While most generations have technically been defined by their data transmission speeds, each has also been marked by a break in encoding methods, or 'air interfaces,' which make it incompatible with the previous generation. 1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.

Read 5G Mobile and Wireless Communications Technology by with Rakuten Kobo. Written by leading experts in 5G research, this book is a comprehensive overview of the current state of 5G.

AT&T's '5G Evolution' Is Not 5G AT&T recently announced its ' network, which isn't 5G. It's AT&T's brand for, the latest incremental advance in 4G LTE, which all major US carriers plan to roll out this year. Gigabit LTE is backwards-compatible with existing phones and runs on existing spectrum. It uses more advanced versions of LTE's existing encoding, along with more antennas and more efficiently consolidated spectrum, to deliver better speeds.

But AT&T's 5G lie also highlights that LTE isn't going away any time soon. 5G, by and large, will operate on very high frequencies, requiring towers or antennas that are relatively close together. It will rely on 4G for broader overall coverage, especially in rural areas. 4G will continue to improve with time, as well. Qualcomm has already announced a 4G modem, the X20,. The real advantages of 5G will come in massive capacity and low latency, beyond the levels 4G technologies can achieve. AT&T and Verizon Launching Pre-5G AT&T and have both pledged to launch 5G home internet systems this year.

At Mobile World Congress in February, Samsung and Verizon showed off the Verizon's 5G service will use. The technologies used in 5G for the home will be closely related to millimeter wave fixed wireless ISPs such as Starry in Boston and Monkeybrains in San Francisco, but with bigger players such as Verizon and AT&T in the mix, they'll be much more widely available. AT&T, for instance, has talked to me about potentially using 5G to replace its old DSL offerings, letting the company deliver a 'quad play' of DirecTV TV service, 5G home internet, wireless phone, and home phone.

This isn't quite 5G, because the 5G standard won't be set until 2018. But Verizon intends to converge its 5G service with the actual standard, and it's trying to use as many elements of upcoming 5G systems as possible. 5G home internet shows one major advantage over 4G: huge capacity. Carriers can't offer competitively priced 4G home internet because there just isn't enough capacity on 4G cell sites for the most homes now expect. This could really increase home internet competition in the US, where, according to a, 51 percent of Americans only have one option for 25Mbps or higher home internet service. 5G home internet is also much easier for carriers to roll out than house-by-house fiber optic lines. Rather than digging up every street, carriers just have to install fiber optics to a cell site every few blocks, and then give customers wireless modems.

Okay, So What's 'Real' 5G? 5G is a new network system that has much higher speeds and capacity, and much lower latency, than existing cellular systems. The technologies to be used in 5G are still being defined, but there are many details on which everyone agrees. 5G networks will use a type of encoding called OFDM, which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though.

The new networks will predominantly use very high frequencies that can transmit huge amounts of data, but only a few blocks at a time. The standard will work all the way from low frequencies to high, but it gets the most benefit over 4G at higher frequencies. 5G may also transmit data over the currently used for Wi-Fi, without conflicting with existing Wi-Fi networks.

That's similar to a technology called LTE-U. 5G networks are much more likely to be networks of small cells, even down to the size of home, than to be huge towers radiating great distances. Some of that is because of the nature of the frequencies used, but a lot of that is to expand network capacity. So 5G networks need to be much smarter than previous systems, as they're juggling many more, smaller cells that can change size and shape. But even with existing macro cells, Qualcomm says 5G will be able to boost capacity by four times over current systems by leveraging wider bandwidths and advanced antenna technologies. The goal is to have far higher speeds available, and far higher capacity per sector, at far lower latency than 4G. The standards bodies involved are aiming at 20Gbps speeds and 1ms latency, at which point very interesting things begin to happen.

Is 5G for Phones, Cars, or Homes? Driverless cars may need 5G to really kick into action. The first generation of driverless cars will be self-contained, but future generations will interact with other cars and smart roads to improve safety and manage traffic. Basically, everything on the road will be talking. To do this, you need extremely low latencies. Arcon Download Italiano Gratis more.

While the cars are all exchanging very small packets of information, they need to do so almost instantly. That's where 5G's sub-1 millisecond latency comes into play, when a packet of data shoots directly between two cars, or bounces from a car to a small cell on a lamppost to another car. (One light-millisecond is about 186 miles, so most of that 1ms latency is still processing time.) Another aspect of 5G is that it will connect many more devices. Right now, 4G modules are expensive, power-consuming, and demand complicated service plans, so much of the Internet of Things has stuck with either Wi-Fi and other home technologies for consumers, or 2G for businesses. 5G networks will accept small, inexpensive, low-power devices, so they'll connect a lot of smaller objects and different kinds of ambient sensors to the internet.

So what about phones? The biggest change 5G may bring is in virtual and augmented reality. As phones transform into devices meant to be used with VR headsets, the very low latency and consistent speeds of 5G will give you an internet-augmented world, if and when you want it. The small cell aspects of 5G may also help with in-building coverage, as 5G encourages every home router to become a cell site.

This book provides a comprehensive overview of the emerging technologies for next-generation 5G mobile communications, with insights into the long-term future of 5G. Written by international leading experts on the subject, this contributed volume covers a wide range of technologies, research results, and networking methods. Key enabling technologies for 5G systems include, but are not limited to, millimeter-wave communications, massive MIMO technology and non-orthogonal multiple access. 5G will herald an even greater rise in the prominence of mobile access based upon both human-centric and machine-centric networks. Compared with existing 4G communications systems, unprecedented numbers of smart and heterogeneous wireless devices will be accessing future 5G mobile systems. As a result, a new paradigm shift is required to deal with challenges on explosively growing requirements in mobile data traffic volume (1000x), number of connected devices (10–100x), typical end-user data rate (10–100x), and device/network lifetime (10x). Achieving these ambitious goals calls for revolutionary candidate technologies in future 5G mobile systems.
