At the concluding MWC 2017 conference, people discussed 5G as a 4G successor. It is reasonable to say that 5G vs. 4G certainly brings a better internet experience, but the problem is that it does not even exist as an industry standard. No one knows what 5G, not to mention how to achieve, when arrived. That's why AT & T's engineers have proposed another technology that aims to deliver higher-speed broadband and greater signal quality, even across less-developed areas of the network.
What is AirGig?
No need for dedicated lines or signal stations, can support almost ubiquitous ultra-fast Wi-Fi, this is AirGig. So what is AirGig?
There is a saying that AirGig is a "power line broadband" technology, referred to as PBL, because its network signal delivery needs to rely on power lines. However, according to the latest available information, this is not the case, because in AirGig's technical description, the signal is not transmitted directly through the power line, the latter is only responsible for guiding it.
AT & T chose to place an ultralight wireless network device on the top of the pole, and wireless signals travel along the powerline to form a connection to each other. Because the popularity of electricity has a long history, it is much wider than the popularity of the Internet. So, with AirGig's power-guided transmission technology, we are able to reach very high speeds of wireless networks almost everywhere. If this vision can be achieved, there is no doubt that another innovation.
But in fact the concept of principle, AirGig's technology is still not "black technology", because it has long been proposed, and technically there is not too high difficulty, but as the times, wireless network It's fast enough that engineers can think about this application.
Previous technical deficiencies were millimeter-wave and very high-frequency technologies, which are considered ideal for use in long-haul point-to-point high-speed wireless networks, whereas the former are short distances and are mainly used around the poles and towers Deploy high-speed network.
One of the most interesting aspects of AirGig technology is its low cost because the wireless devices on the pole can be made of plastic and are relatively inexpensive. Most importantly, there is even no need for a power connection between this device and the utility pole, as the former can directly generate inductively coupled electricity using the magnetic field around the latter to provide electricity for itself. As a result, the cost of deploying AirGig is even smaller because you do not need to make more changes.
Necessity of AirGig
According to AT & T's survey data, since 2007, the data volume on the network where it is deployed has soared by 250,000%. However, the prolongation of the network video industry has accelerated the demand. Even without mentioning those emerging developing countries, even the suburbs of the United States have very slow and even no Internet problems. One reason AT & T took AirGig in the right direction is its ease of deployment - after all, no network can make up for it without electricity.
But in any case, fiber-optic networks are still a gold standard that is very popular, well-accepted and accepted by all consumers and will have potential in the future. Fiber network deployment has been so wide, why do we need AirGig, it really there is any reason to let people give up the standard that has been accustomed to using?
As we said above, the answer to the question is still "money." Although fiber-optic networks can theoretically reach alarming rates, the cost issue can not be overlooked, not to mention that you need to route, amplify, and bring that to every home. Because of this, the network is more heavily deployed in the more prosperous regions than electricity. With AirGig, the equivalent of a high-speed network has a cheaper deployment plan.
As for the network speed, AirGig performance itself is not bad, but as a recently planned application technology, its speed performance, of course, not as good as the traditional program. In fact, some telecom operators said they have achieved 20Gbps, less than 1ms delay in the laboratory network experience. So some people think AirGig is more likely to be a transitional technology.
AT & T has said that the company has always put ultra-high-speed Internet implementation first place, whether it is wired or wireless technology. In this regard, AirGig may seem a bit powerless compared to traditional fiber solutions. However, AT & T still has confidence in this technology, it thinks can use AirGig in the future 5G network service.
The future of AirGig
In recent years, AT & T has been conducting outdoor BPL for a long time, but it did not reveal until February of this year that it would conduct further discussions with the utility on the AirGig trial. By the end of 2017, AT & T will pilot in two locations, one in the United States and one in the other. Given that AirGig technology is primarily low-cost to deploy, AT & T may have ambitions to push it to the world.
According to information previously disclosed by AT & T executives, the company will work with a large number of power companies and utility companies to persuade them to agree that AT & T will use its power network. The momentum so vast, we also hope to see the actual application of AirGig.
But that does not mean that we will soon see the AirGig coming out, because according to the discussions at the MWC 2017 conference, the 5G network will not be realized until 2020 at least. Even then, AirG
