Share the knowledge

With the upcoming of 5G technology, we will see great impact, not only on the ease of our communication, but also on digital or internet marketing that is using more and more video content. Greater bandwidth and much less latency will certainly be main points in supporting much better experience of video viewing for all of us. In order to gain a deeper understanding of how 5G technology works, we present the above video to watch with its transcript in the following section.

The following is the transcript of the video:

Every new generation of wireless networks delivers faster speeds ad more functionality to our smartphones. 1G brought us the very first cell phones. 2G let us text for the first time. 3G brought us online. And 4G delivered the speeds that we enjoy today. But as more users come online, 4G networks have just about reached the limit of what they’re capable of at a time when users want even more data for their smart phones and devices.

Now we’re headed toward 5G the next generation of wireless. It will be able to handle a thousand times more traffic than today’s networks and it’ll be up to 10 times faster than 4G LTE. Just imagine downloading an HD movie in under a second and then let your imagination run wild. 5G will be the foundation for virtual reality, autonomous driving the Internet of Things and stuff we can’t even yet imagine. But what exactly is a 5G network. The truth is experts can’t tell us what 5G actually is because they don’t even know yet. But right now there are 5 brand new technologies emerging as a foundation of 5G: millimeter waves, small cells, massive MIMO, beam forming and full duplex.

First up technology number one, millimeter waves. Your smartphone and other electronic devices in your home use very specific frequencies on the radio frequency spectrum, typically those under 6 gigahertz. But these frequencies are starting to get more crowded. Carriers can only squeeze so many bits of data on the same amount of radio frequency spectrum. As more devices come online, we’re going to start to see slower service and more dropped connections.

The solution is to open up some new real estate. So researchers are experimenting with broadcasting on shorter millimeter waves, those that fall between 30 and 300 gigahertz. This section of spectrum has never been used before for mobile devices and opening it up means more bandwidth for everyone. But there is a catch, millimeter waves can’t travel well through buildings or other obstacles and they tend to be absorbed by plants and rain.

To get around this problem we’ll need technology number 2, small cell networks. Today’s wireless networks rely on large high powered cell towers to broadcast their signals over long distances, but remember higher-frequency millimeter waves have a harder time traveling through obstacles which means if you move behind one you lose your signal. Small cell networks would solve that problem using thousands of low-power mini base stations. These base stations would be much closer together than traditional towers forming a sort of relay team to transmit signals around obstacles. This would be especially useful in cities as the user moved behind an obstacle. His smartphone would automatically switch to a new base station in better range of his device, allowing him to keep his connection.

Next up, technology number three massive MIMO. It stands for multiple-input multiple-output. Today’s 4G base stations have about a dozen ports for antennas that handle all cellular traffic, but massive MIMO base stations can support about a hundred ports. This could increase the capacity of today’s networks by a factor of 22 or more. Of course, massive MIMO comes with its own complications. Today’s cellular antennas broadcast information in every direction at once and all of those crossing signals could cause serious interference which brings us to the next technology.

Technology number 4, beamforming. It is like a traffic signalling system for cellular signals. Instead of broadcasting in every direction it would allow a base station to send a focused stream of data to a specific user. This precision prevents interference and it’s way more efficient. That means stations could handle more incoming and outgoing data streams at once. Here’s how it works. Say you’re in a cluster of buildings and you’re trying to make a phone call. Your signal is ricocheting off of surrounding buildings and criss-crossing with other signals from users in the area.

A massive MIMO base station receives all of these signals and keeps track of the timing and the direction of their arrival. It then uses signal processing algorithms to triangulate exactly where each signal is coming from and plots the best transmission route back through the air to each phone. Sometimes it’ll even bounce individual packets of data in different directions of buildings or other objects to keep signals from interfering with each other. The result is a coherent data stream sent only to you which brings us to technology number 5 full duplex.

If you’ve ever used a walkie talkie, you know that in order to communicate you have to take turns talking and listening. That’s kind of a drag. Today’s cellular base stations have that exact same hold up. A basic antenna can only do one job at a time, either transmit or receive. This is because of a principle called reciprocity which is the tendency for radio waves to travel both forward and backward along the same frequency. To understand this it helps to think of a wave like a train loaded up with data. The frequency it’s traveling on is like the train track and if there’s a second train trying to go in the opposite direction on the same track, you’re going to get some interference. Up until now the solution has been to have the trains take turns or to put all the trains on different tracks or frequencies. But you can make things a lot more efficient by working around reciprocity.

Researchers have used silicon transistors to create high speed switches that halt the backward role of these waves. It’s kind of like a signaling system that can momentarily reroute to train, so that they can get past each other. That means there’s a lot more getting done on each track, a whole lot faster. We’re still working out many of the kinks with millimeter waves, small cell networks, massive MIMO, beam forming and full duplex. In fact all of 5G is still a work in progress. It will likely include other new technologies, too and making all of these systems work together will be a whole other challenge. But if experts can figure that out, ultra fast 5G service could arrive in the next five years.

Teknologi 5G dan Dampaknya Terhadap Internet Marketing

Dengan akan datangnya teknologi 5G (diperkirakan sekitar tahun 2020) maka tentunya akan memberi dampak , bukan hanya pada semakin mudahnya komunikasi kita, namun juga terhadap perkembangan internet marketing. Trend internet marketing sekarang dengan semakin banyak konten video diproduksi, maka teknologi 5G yang menawarkan bandwidth semakin besar dan delay semakin kecil tentu akan memberi kontribusi besar terhadap perkembangan dan pilihan-pilihan cara dalam internet marketing ke depannya.

Berikut adalah 5 teknologi yang mendukung perkembangan teknologi 5G:
1. Gelombang milimeter, yang akan memakai frekuensi lebih tinggi antara 30 – 300 Gigahertz untuk komunikasi mobile
2. Sel yang lebih kecil, namun dengan jumlah tower semakin banyak untuk mengurangi degradasi sinyal
3. Jaringan MIMO (Multiple Input Multiple Output) yang semakin banyak sehingga kapasitas jaringan bisa meningkat 22 kali
4. Beam forming yang akan membuat broadcasting semakin terarah sehingga mengurangi interferensi dan semakin efisien
5. Full duplex, di mana sinyal keluar dan datang akan diberikan rute dengan tetap menggunakan jalur yang sama
