What is a 6GHz network?

A 6GHz band network is not a 6G network, but rather a WiFi wireless network that operates in the 6GHz band. There are two common frequency bands we use for WiFi: 2.4GHz and 5GHz, but both have their own advantages and disadvantages. 2.4GHz has a frequency range of only 70MHz, which means that it has less traffic but travels farther, while 5GHz, with its 500MHz bandwidth, has a lot of traffic but doesn't travel as far as 2.4GHz. -People, see here is not scolding Xuan father? But the problem is that you did not read the question carefully.

According to statistics, in the next five years, the average family will have about 30 smart devices. The current WiFi is limited to support devices in areas such as train stations, shopping malls, and other mobile device-intensive areas where network congestion often occurs. 6GHz WiFi can solve the problem of "network congestion".

Usually, the higher the bandwidth, the higher the bandwidth, but the worse the penetration ability, 6GHz band network and the mainstream 5GHz compared to the bandwidth will be higher, but the coverage area is limited, suitable for small-scale applications at home. 6GHz can be a solution to the problem of traffic flow can also solve the problem of the short propagation distance, and between the device of the wireless interference will also be less. In other words, if you use a 6GHz router, the feeling of a slow network and someone grabbing the network will no longer exist.

In fact, as early as April 23rd of this year, the US FCC (Federal Communications Commission) voted to open up the new unlicensed 6GHz band, establishing a newer generation of WiFi 6E standards and introducing the 6GHz band.

Some analysts say that smartphones may be the first consumer devices to adopt next-generation WiFi. It is predicted that by 2021, 316 million WiFi 6E-enabled devices will ship. Following smartphones, tablets are expected to follow suit and are expected to be adopted by TVs in 2022. For now, the tech industry seems to be waging a battle around 6GHz WiFi.

What does the codename WiFi 6E mean?

Before 6GHz networks hit the ground in testing, and indeed at a press conference earlier this year, the WiFi Alliance announced a new term to differentiate upcoming WiFi 6-enabled devices in the 6GHz band - WiFi 6E.

However, the organization pointed out that the 6GHz band can't be used for WiFi just yet, as it's still awaiting approval from regulators around the world. Recently, FCC Chairman Ajit Pai expressed his intent to make the 6GHz band available for WiFi, so that could mean it will soon be approved in the US.

Phil Solis, head of research at IDC, said that because of the huge potential for WiFi in the 6GHz band, its use is likely to increase rapidly.

Once regulatory approval is granted, smartphones and consumer access points are expected to be the first devices to adopt the technology, followed by business access points.The Wi-Fi Alliance says WiFi 6E will be particularly useful for augmented reality and virtual reality. It will also help address the lack of WiFi spectrum by providing contiguous blocks of spectrum that can accommodate 14 additional 80MHz channels and seven additional 160MHz channels.

While higher spectrum can provide faster speeds and greater capacity, it has less range and is more easily blocked by obstacles. As a result, it's unlikely that the 6GHz band will go on to replace the existing WiFi band. Of course, everyone will only see the real benefits of WiFi 6E when it's actually available, and right now, it's not clear when that will happen.

Who's going to use 6GHz networks?

The FCC's proposal for the 6GHz band would open up standard-power Wi-Fi connections, as well as low-power indoor connections (LPI) and very-low-power connections (VLP). The latter two are how machine-to-machine communications (M2M) makes its living, and M2M could play a key role as the Internet of Things continues to grow.

Dr. Raul Katz, director of business strategy research at the Columbia Institute for Tele-Information and president of Telecom Advisory Services, LLC, argues that the LPI frequencies used for The increase in LPI spectrum capacity for M2M communications, which is expected to increase from the current installed base of 118 million devices to 214 million by 2025, will allow for wider deployment of IoT devices, contributing up to $44 billion worth of value to GDP over the next five years.

Opening up the connectivity space in the 6GHz band will enable a new generation of AR/VR applications, which will generate up to $14 billion in revenue for US companies selling hardware, software and content over the next five years. This in turn will have a spillover effect on GDP equal to roughly $26 billion.

Faced with such a large market, vendors are also very active. Qualcomm has officially announced a full range of Wi-Fi 6E solutions, the second generation of the Networking Pro family, including the 1610, 1210, 810, and 610 products, which extend the key feature set of Wi-Fi 6 to the 6GHz band to deliver gigabit speeds, high bandwidth, and low latency for a wireless experience comparable to that of a wired network.

Need to update your WiFi device

WiFi 6E devices will be backward compatible with WiFi 6 and previous WiFi standards. However, to take advantage of those new 6 GHz channels in WiFi 6E, users will need to use a device that supports it. In other words, users will only be able to use WiFi 6E if they pair a WiFi 6E-enabled client device, such as a laptop or smartphone, with a WiFi 6E-enabled access point.

For example, even if a user has a bunch of WiFi 6 devices and a WiFi 6E-enabled router, none of the user's devices will be able to communicate over WiFi 6E. They will all be using WiFi 6 on a typical 5GHz or 2.4GHz channel.

Don't wait for Wi-Fi 6E......

In technology, there's always something new. For WiFi, it's now WiFi 6E.

Over the next few years, it's likely that users will buy new devices that increasingly have WiFi 6. But users probably won't get WiFi 6E-just WiFi 6-on those devices.

WiFi 6E sounds great, but it's not there yet.

Note that WiFi 6E's 6 GHz band is different from the 60 GHz band; WiFi 6E's 6 GHz will be similar to Wi-Fi's 5 GHz, and WiGig is ideal for faster data rates over shorter distances.

6G in its infancy

That said, most of the folks entering this article are still mentally relieved that it's 6G.

"6G rates are in different scenarios are different, for some short-range connections such as holographic interactions, the rate may be as high as 1Tbps (1T=1024G), while for some simple information-gathering connections, the rate may be at the Kbps level."

Liu Guangyi said that from the current global research and discussion, 6G research and development will be divided into two major phases from 2019 to 2025 and from 2026 to 2030.

In Liu Guangyi's view, the biggest change in 6G relative to 5G may be the change brought about by the development trend of DICT (Deep Integration of DT with IT and CT in the era of big data) technology. In addition, according to the mobile communications industry, "use a generation, do a generation, see a generation" of the 10-year iteration law, the industry's goal is to have a large-scale 6G commercial capability in 2030.

In November 2019, the national 6G technology research and development promotion working group and the overall expert group were announced, marking the official launch of China's 6G technology research and development work. In addition to China, the United States, Finland, Japan, South Korea and other countries have begun research on 6G.

Currently, the global 6G technology research is still in the exploratory start-up stage, and now the focus is on how to define the vision and needs of 6G, as well as research on potential key technologies for 6G. 6G-oriented technology research needs to comprehensively consider three driving forces: first, the demand for new applications and new scenarios inspired by technological progress; second, the experience and new challenges in the development and application of 5G; and third, the development trend of new technologies, such as the deep convergence of DICT.

Although U.S. telcos were among the first in the world to commercialize 5G, they lagged behind Chinese companies in terms of 5G scale as well as technical standards.

For such a situation, the United States has always hoped to bypass the 5G, a few days ago, the United States International Development Finance Corporation "CEO Bohler even expressed the intention to leapfrog the development of direct investment in 6G, in an attempt to regain the dominant position in this field, bypassing the Chinese company.

For the United States want to bypass 5G directly into the 6G idea, the Global Times interviewed communications expert Xiang Ligang, the latter said (bypassing 5G directly on the 6G) is unlikely, from 1G to 2G, 3G to 4G, 5G, network communications technology are gradually accumulated, 5G is more than communications technology, but a complete social intelligence system.

Xiang Ligang believes that the U.S. 6G communication technology may do better than 5G, but how to skip the development of other industries linked to 5G is a problem.

In addition, Xiang Ligang also said that at present, domestic experts believe that 6G can not be composed of a separate communications network, the future of communications technology is also to 5G technology as the core, with 6G as a supplement, so that the 5G technology to become more complete.

Overall, Xuan dad think, expected to worry about 5G quickly reduced to transition, as well as early experience, said, small partners around the home of the 5G base station more?
