You can’t avoid the 5G hoopla at CES this year. It’s been building since the 2018 Consumer Electronics Show. Everyone wants you to know how great 5G home internet will be, from Samsung and Intel to cellular providers and smartphone manufacturers. Samsung dubbed it “wireless fiber,” implying that it would provide super-fast, low-latency internet to anybody, wherever. 5G is quicker than today’s ordinary residential cable internet connection, and it’s also wireless.
What Exactly Is 5G Internet?
5G is the industry standard that will replace the widely used 4G LTE standard, just as 4G did for 3G. 5G means “fifth generation,” which is the standard’s fifth generation. This standard is intended to be far quicker than the existing 4G LTE standard. However, it’s not only about improving smartphone internet connections. It all comes down to providing speedier wireless internet for anything from linked automobiles to smart homes and Internet of Things (IoT) gadgets.
Your smartphone and all other cellular-connected gadgets will likely utilize 5G technology in the future rather than the 4G LTE technology used today.
What Is the Speed of 5G Internet?
5G has a lot of promise for IT businesses. While 4G has a theoretical high speed of 100 megabits per second (Mbps), 5G has a potential top speed of 10 gigabits per second (Gbps). That implies 5G will be a hundred times faster than present 4G technology, at least at its theoretical maximum speed.
According to the Consumer Technology Association, a two-hour movie may be download in only 3.6 seconds on 5G, compared to 6 minutes on 4G or 26 hours on 3G.
It’s not simply about throughput. 5G promises to cut latency dramatically, resulting in quicker load times and increased responsiveness while doing almost anything on the internet. The standard predicts a maximum delay of 4 milliseconds on 5G, compared to 20 milliseconds on 4G LTE today.
5G outperforms existing residential cable internet connections and is more akin to fiber at these speeds. Comcast, Cox, and other landline internet providers may face stiff competition, particularly if they’re the only choice for fast home internet in a particular region. Wireless providers may provide an alternative without connecting physical connections to every residence.
The presenters encouraged us to think of 5G as providing super-fast, almost infinite connectivity to all devices, everywhere. Of course, data restrictions are impose by internet service providers in the real world. Even if your cellular carrier provided you a 100 GB data cap. Which is significantly more than most plans today—at the theoretical maximum speed of 10 Gbps, you could use it up in a minute and 20 seconds. It’s unknown what kind of limitations carriers will apply in the end or how this would impact use.
What Is 5G Internet and How Does It Work?
To attain these high speeds, 5G employs a variety of technologies. There isn’t just one kind of innovation at work here. Although the IEEE Spectrum magazine does a beautiful job of discussing many technical issues in more depth, here’s a fast rundown.
From 4G, the new standard will utilize an entirely new band of radio airwaves. 5G would employ “millimeter waves,” which are transmitted at frequencies between 30 and 300 GHz. Rather than the bands below 6 GHz that were previously used. These were formerly solely used for satellite and radar system communication. However, since millimeter waves cannot readily pass through buildings or other solid things, 5G will need “small cells,” which are tiny miniaturized based stations that may be installed every 250 meters across busy metropolitan areas. In such places, they would give considerably greater coverage.
“Massive MIMO” is also use by these base stations. “Multiple-input multiple-output” (MIMO) is an acronym for “multiple-input multiple-output”. You could even have a home wireless router with MIMO technology, which means it has several antennae and can communicate with numerous wireless devices simultaneously rather than switching between them fast. On a single base station, massive MIMO will require hundreds of antennas. They’ll also use beamforming to guide those signals better, focusing the wireless signal in a beam aimed at the device and eliminating interference from other devices.
5G base stations will also operate in full-duplex mode, which means they will be able to broadcast and receive data on the same frequency at the same time. They now have to switch between transmitting and listening modes, which slows down the process. That’s only a sample of the technology use to make 5G so fast.

When will it be release?
The following is an update for 2020: Verizon, AT&T, T-Mobile, and Comlink have all started deploying 5G in specific areas throughout the United States. T-Mobile, for example, has launched a countrywide network. Although one that uses a low-band spectrum instead of the faster millimeter wave technology. AT&T has also introduced 5G in a few places. The networks aren’t as important right now since most handsets, even the newest iPhones, don’t enable 5G. We continue to advise against purchasing a modern 5G phone. More time is require to create both the networks and the phone hardware.
Verizon will launch a non-standard version of 5G in the United States in the second half of 2018. Utilizing it for residential internet connection in five locations. Cell phones that support 5G won’t be able to connect, but it won’t be for phones in the first place. It’ll merely be a means to provide high-speed home internet access.
AT&T said it will start bringing out 5G phones in late 2018, although a significant 5G deployment isn’t expected until 2019. T-Mobile has said that the deployment would begin in 2019, with “nationwide coverage” scheduled in 2020. Sprint said it would start rolling out 5G in late 2019. With timetables like this, 5G technology is unlikely to be widely use until 2020.
Qualcomm, which produces the processors used in many Android phones, has said that 5G phones will be available in 2019. Yes, you’ll need a new phone and other cellular devices that enable 5G. Just as cellular operators will need new gear to support 5G.
You’ll hear a lot more about 5G as the deployment gets underway, but the hype mill is already in full swing. Take the potential maximum speeds with a grain of salt, and expect to wait a few years for broad coverage.
