In the post-epidemic period, as people’s daily life and business operations in Asia gradually return to normal, the digital model will continue to become the norm. For many organizations, the ability to support a wide range of video and voice streaming media applications, ensure large data downloads in distributed hybrid and remote office locations, and achieve fully digital operation in large interconnected locations has become critical. Therefore, investing in a new generation of Wi-Fi 6 solutions plays a key role in ensuring such a large-scale high-speed connection. This type of investment can provide enterprises with the key functions they need to help them cope with the current escalating connectivity requirements.
Provide excellent connection performance, Wi-Fi 6 can meet many challenges
As the latest generation of Wi-Fi technology, Wi-Fi 6 can effectively alleviate the problems that occur when multiple devices are connected to the same network. This technology has many advantages, especially the speed is up to four times faster than Wi-Fi 5, and the maximum throughput speed has been increased from 3.5 Gbps to 9.6 Gbps. In addition, Wi-Fi 6 not only extends the battery life of connected devices, it also provides stronger mission-critical security by supporting the latest generation of Wi-Fi standard WPA3™. The WPA3™ standard has been certified by the Wi-Fi Alliance, an industry organization, and can provide the market with the most advanced wireless security protocol. With these features, Wi-Fi 6 can bring better performance to crowded environments with hundreds of simultaneously connected devices and users. In a nutshell, Wi-Fi 6 improves the core performance of Wi-Fi and can address the following key challenges:
• Mobility: When a user moves out of the coverage of an access point (AP) and needs to connect to another AP in the same network, the WLAN network must move the user’s device smoothly without interruption.
• Interference: Walls and floors, as well as other Wi-Fi networks and devices, can interfere with Wi-Fi networks, causing network congestion and poor user experience.
• Security: The lack of the best network security protection measures will allow malicious attackers who intend to steal intellectual property, money and personal identity to take advantage of it. For example, the 2017 KRACK vulnerability threatened billions of Wi-Fi devices. Although the industry has done its best to patch the vulnerability, its variants are still a security threat to this day.
• Standards: The explosive growth of IoT devices has given birth to a whole set of new wireless connection standards including Bluetooth Low Energy, Zigbee, LoRA, NB-IoT, etc. Therefore, traditional Wi-Fi access point hardware will also need to be able to support connection use cases other than Wi-Fi.
• Infrastructure: Supporting AP-related infrastructure is equally important. Technologies such as multi-gigabit Ethernet, 802.3bz, and the latest PoE standards (such as 802.3bt) are essential to provide excellent Wi-Fi performance.
• Deployment: Physical constraints may hinder the deployment of Wi-Fi in street furniture, vehicles, and other space-constrained locations (such as street lights). In order to provide a high-speed and seamless Wi-Fi experience, it will be necessary to define dimensions that are not currently required by various Wi-Fi standard subjects.
• Density: An ultra-dense environment with a large number of users and devices in a small area, such as a stadium or a transportation hub, will bring unique Wi-Fi challenges, resulting in a degradation of Wi-Fi network performance.
• Applications: Nowadays, 4K video streaming, virtual and augmented reality, and game live broadcasts are becoming more and more popular. Compared with simpler applications such as music streaming, such applications consume more bandwidth.
Both users and network operators expect Wi-Fi that is safe, reliable, high-performance, and always suitable for all types of devices. However, achieving this goal is far from easy. For many years, CommScope has concentrated on researching and developing various innovative technologies to cope with high-density environments, reduce interference, optimize liquidity, and ensure network access capabilities. In addition to its own Wi-Fi 6 product portfolio, CommScope’s technology can also minimize the problems common in previous generation Wi-Fi solutions.
Wi-Fi technology continues to upgrade, and the application fields are better and wider
As we move towards an interconnected future, infrastructure solutions are also constantly improving. Solutions such as more powerful access points can provide various high-load scenarios in many fields such as school parks, hotels, manufacturing, and healthcare. Strong support. Wi-Fi 6 is designed to expand in accordance with the digital needs of enterprises and consumers, as a viable solution to help solve today’s business problems, and to plan ahead for new challenges in the future. It is expected that in the next three to five years, the adoption rate of transformative use cases in the following industries will increase:
• Improve wireless coverage in buildings: Wi-Fi 6 enables employees or visitors’ mobile phones to seamlessly connect to the Wi-Fi network when entering the building, without being affected by calls or text messages.
• Gain influential insights from the edge: Wi-Fi 6 enables enterprises to obtain data insights with ultra-low latency and respond in real time to business needs such as maintenance and repair in the automotive and aerospace fields, and patient care in telemedicine.
• Promote cost-effective integration of the Internet of Things: Wi-Fi 6 enables the integration of wireless resources on a single platform, which not only improves visibility, but also reduces costs.
• Facilitate distance learning: Many schools are making every effort to build digital classrooms through e-learning, online testing, web notebooks, and even virtual reality. Schools have begun to adopt Wi-Fi 6 to support the substantial growth of connected devices and streaming video through reliable and always-on Wi-Fi.
On the other hand, when the current Wi-Fi 6 deployment is still in full swing, the industry has begun to prepare for the Wi-Fi 6E upgrade. Wi-Fi 6E will be able to provide the determinism, low latency, and highly reliable quality of service (QoS) required for next-generation wireless applications. The additional spectrum allocated to Wi-Fi 6E will solve many current challenges, such as:
• Reduce congestion: The current Wi-Fi provides 27 non-overlapping 20 MHz channels, while the number of 20 MHz channels for Wi-Fi 6E will increase to 59. The newly added channels will alleviate many congestion problems and better support a greater number and types of interconnected devices.
• Increased speed: 1,200 MHz of continuous spectrum supports 80 MHz (14 new channels) and even 160 MHz (7 new channels) channel bonding. This is good news for high-density venues such as conference centers and auditoriums. At home, Wi-Fi and Wi-Fi 6E will supplement the multi-gigabit speeds of the latest optical fiber and DOCSIS 3.1 networks in terms of speed. By combining multiple 20 MHz channels into a wider, higher-throughput 80 MHz or 160 MHz channel, existing Wi-Fi 6 clients can reach their maximum speeds, unlike those with smaller channel widths It is as limited at runtime. Wi-Fi 6E can also support more wired alternative applications, such as wireless point-to-point and indoor mesh backbone links.
• Reduce latency: Wi-Fi 6E will only support OFDMA, MU-MIMO, 1024 QAM and 6 GHz devices. All other traditional Wi-Fi devices will be limited to the 2.4 GHz and 5 GHz frequency bands. By separating the traffic, the speed required for ultra-latency sensitive applications such as AR/VR, gaming, and real-time imaging can be ensured. In the future, new APs need to provide downward compatibility so that devices can support Wi-Fi 6E and the old frequency bands at the same time.
The importance of Wi-Fi 6 is highlighted, escorting multi-device connections
By 2023, the IoT market in the Asia-Pacific region is forecast to grow to 398.6 trillion U.S. dollars, and the adoption rate of connected devices will also increase. The proliferation of connected devices and their users is pushing the 600 MHz bandwidth of Wi-Fi 5 to the limit, but connecting more and more devices to Wi-Fi 5 is not a long-term solution. After all, there are only a certain number of devices available at any time. To communicate. This will inevitably lead to equipment speed throttling, which will be extremely disadvantageous for telemedicine and dense environments such as hospitals or schools where speed and accuracy are critical.
Given that the digital economy in the post-epidemic era will rely more on connectivity, the deployment of Wi-Fi 6 can help organizations achieve robust and seamless multi-device connections to ensure optimal network performance in crowded or remote areas. Data intelligence and management, as well as the high usage rate of social platforms and chat applications, have become increasingly prominent in promoting corporate business. Therefore, the strength and speed of the network have become the key to the company’s daily operations. Wi-Fi 6 can provide higher speed and greater capacity for interconnected devices before speed throttling occurs, and by supporting lower latency and more efficient data transmission, it can solve the current limitations of previous generation technologies and improve Good connectivity enables diverse office environments and encourages people to stay connected when working remotely.
With the increasing popularity of 5G broadband, by 2025, nearly a quarter of the total number of mobile connections in the Asia-Pacific region will be supported by 5G networks. At the same time, the industry will work together to increase the available spectrum of Wi-Fi in the 6GHz frequency band, and use all licensed and unlicensed spectrum to meet consumer needs. The importance of Wi-Fi to enterprises will be unprecedented, and the demand for networks will continue to grow exponentially. Therefore, Wi-Fi 6 will become a powerful choice for corporate business in the Asia-Pacific region and wireless coverage in densely populated areas.
