Wireless Internet has changed our lives, giving us the ability to do very much and in different places — at home, at work and even somewhere in the wilds of nature. We don’t even think about it until it works. It’s like oxygen: we take it for granted until it ends. And that’s when the panic starts.
People who develop and implement standards of wireless Internet, for many years, pursue the same goal: to make the connection faster, and the energy to spend less. Now they are faced with a dilemma of a different kind. In near future we can expect an unprecedented increase in the number of new devices that will come on the market. Billions of sensors for smart homes, industrial devices and computers with artificial intelligence. The systems that currently exist, simply can not cope with the huge amount of data.
To provide the present coating 5G, you need a new wireless infrastructure, including new routers are like mini-rigs of the company “Verizon” and the new device.
In the next two years great changes are expected in everything around us wireless connections. This Wi-Fi the new generation under the name Wi-Fi 6; this is a more powerful Bluetooth standard called Bluetooth 5; and, of course, is 5G. This somewhat mysterious name given to the planned upgrade of our cellular networks. They all play a role in the new era of giperbolicheskoi when everything with exceptional ease will enter the network.
In the coming years you all ears will buzz with news about wireless protocols, because each operator, each manufacturer of the chipset and manufacturer of the gadgets will try to gain dominance in the field of 5G. But what means this abbreviation? A definite answer to this question is no.
First, you should know that in some cases, 5G means nothing. The company “A. T. & T.” decided to call signal indicator networks of the fourth generation LTE on some phones 5G E, if the connection provided there is faster; but it will still be fiber optic network of the fourth generation. The financial Director of this company John Stephens (John Stephens) said that this name change is quite appropriate, as the upgrading of rigs will immediately lead to higher quality wireless services.
Overall, however, the 5G is an evolutionary achievement of cellular communication, promising blazing-fast Internet speed which will be many times greater than what we have in cellular networks and even in our home wireless Internet.
5G appears uneven and not even very fast. First, the operators inserted components in 5G LTE networks of the fourth generation, which allows to improve their work. Soon you will hear about the technology 5G NR for “new radio”, which will initially be used for modernization of existing networks of the fourth generation. Primarily the focus will be on home broadband network. So, Verizon will offer the modem of company “D-link” type 5G NR Enhanced Gateway that picks up any middle 5G signal and converts it into a Wi-Fi so it can use the existing devices.
Real 5G will come later, because it need a brand new expensive infrastructure, including tiny routers placed literally everywhere to work with new radio bands, where the waves are much shorter than in the existing ranges of mobile operators. It will be the millimeter waves.
5G in the short-wave millimeter range and wirelessly transmits large amounts of data over short distances. The antenna is also small, this means that the receiving chip can be embedded in tiny devices. The short-wavelength makes it possible to transmit more data at smaller distances. 5G also promises a very small amount of latency, or lag time, which is very important for streaming video games and self-driving cars.
But the full connection 5G we will get until mid 2020-ies. However, if operators make it a fairly quick and cheap, anything else we might need.
Instead of increasing the theoretical maximum Wi-Fi speed (which in any case we are unlikely to see), company of Alliance compatibility, wireless equipment WECA working to improve the processing of network traffic. New routers that support Wi-Fi 6, known as 802.11 ax will help to better co-exist on our TV, STB, smart phones and refrigerators. This is true, but think wider.
One of the first routers that will support Wi-Fi 6, this Archer AX11000 company “Ti-PI link”. He looks like an alien spacecraft and its antenna is made to connect your devices.
“In this new environment, the user will have a completely different feeling, is he at the train station in Tokyo or in the crowd at the stadium during the game, the super bowl,” said Vice President of WECA marketing Kevin Robinson (Kevin Robinson).
This will be possible thanks to two new technologies. The first is called MU-MIMO (which means “multi-user, multi-input, multi-output). It will allow the radio transmitter to simultaneously process requests from multiple devices. The second is called OFDMA (independent parallel access with frequency division). She smashes a separate channel on podniesie, expanding opportunities to work with numerous devices.
Robinson compares MU-MIMO with increasing number of trucks in service delivery, and OFDMA with opportunity for each truck to make several stops along the way. What will it give users? Their devices do not have to puff hard, to provide a connection in crowded network. Give me a call over Wi-Fi at the stadium when I place shots on Instagram, and the signal will be held for the first time.
It is important to note that these technologies do not just accelerate the downloading of large volumes and stream Netflix (Netflix). They are intended primarily to transmit tiny messages of our chats and apps and with devices in our smart homes, which today have to wait too long.
Some gadgets already support Wi-Fi 6, but in 2020, when will start to operate the certification program of the Alliance WECA, we should expect an influx of new devices.
Nighthawk AX12 is another similar to the alien ship a router that supports Wi-Fi 6. It is compatible with existing ranges of Wi-Fi, so you can easily buy now.
Bluetooth is used when connecting devices to each other in order to transmit commands and other small amounts of data. You can use Bluetooth to connect headphones to a smartphone or to a temperature sensor in your pool talk to your application. In the future will be to communicate between a network of sensors in large scale farms, museums will take you through the halls with exhibits, and shopping malls will give you precise instructions, so you don’t get lost.
Bluetooth 5 is the newest standard and it already works in many devices such as watches Apple fourth series, the latest smartphones from Apple, Samsung and other manufacturers. This standard gives a lot of energy savings. If the finder of lost things Tile used wifi, not Bluetooth, its battery worked for a few months.
The new generation of Bluetooth more range and higher reliability. “If earlier Bluetooth “punch” to your signal one or two walls, now he gets three or four walls,” says Chuck Sabin (Sabin Chuck), working as a senior Director of business strategy development and planning standards organization Bluetooth SIG.
Speaking of Wi-Fi Bluetooth 5 and 6, it should be borne in mind that they give the most benefits, even if you are right you can all take advantage of it. Firm “D-link”, “NETGEAR” and others are already implementing Wi-Fi routers 6. With router nodes in the network Wi-Fi 6 can coordinate all the conversations happening between different wireless access points, allowing connection you will be faster. New standards and devices are usually also compatible with previous versions, so they can work with your current and future devices.
What about 5G? Here everything is difficult. Your life in this generation of standards depends on where you live, the services of any operator you use and what devices they own. Some manufacturers have already shown prototypes of the phones 5G, and this year there will be many other devices. But wait the appearance of Afyon 5G in 2019 is not worth it. Apple is known for its expectant when adopting new standards, especially those that belong to wireless operators.
I’ll give the following recommendations. Don’t rush to live the wireless life of the future, but don’t very much from that future to keep up. Even if you are not planning immediately to litter your home with smart things, and especially to go out tonight in the car-robot, a new era of universal connectedness still promises to make communication faster and more efficient for everyone.
