Over more than two decades, Wi-Fi technology has become ubiquitous, and has served as the de-facto wireless broadband Internet connectivity from home, enterprise, and public facilities such as hotels, airports and convention centres. In particular, during the COVID-19 outbreak, Wi-Fi connectivity provided the life-line for students, educators, doctors, and businesses, and Internet service providers have seen huge increases in their traffic via Wi-Fi networks. Indeed, during the pandemic, communities across the world worked together to close the digital divide by providing Wi-Fi services. While Wi-Fi technology and the Internet have proved to be resilient and reliable over these decades, notably during the pandemic, the expectations from Wi-Fi networking have grown from broadband Internet access to applications in factories, warehouses, hospitals, and emergency response, etc. In these use-cases, requirements such as throughput guarantees, low latency (including packet latency bounds), and even seamless mobility are critical. Despite the rapid adoption of the latest physical layer techniques, including power saving mechanisms, in the new generations of Wi-Fi technologies, the industry has witnessed limited deployment of Wi-Fi networks in the above emerging application areas.
Our objective for this session is to highlight the features of the new generations of Wi-Fi technologies, understand their capabilities, and identify the gaps that are hindering the wide scale deployment of Wi-Fi technologies in emerging applications such as Industry 4.0, safety, interactive gaming, and so on. One can argue that Wi-Fi technology has performance limitations which can be traced back to air-time resource sharing mechanisms, the distributed control plane, and many other design choices that were made due to the nature of the unlicensed operation, and the constant need for legacy compatibility. On the other hand, some can draw the comparison with mobile cellular networks, which, operating in licensed bands, have also gone through a generation to generation evolution by introducing new physical layer techniques, with centralized control mechanisms, and are able to continuously support the emerging applications in a reliable manner, while sacrificing backward compatibility with the previous generations. Now with the emergence of “private” networking (or NPN (non-public networking)), applications such as Industry 4.0, mission critical telehealth, and remote factory operation are becoming a reality. Therefore, Wi-Fi networking may be at an inflection point. While Wi-Fi technologies have adopted cutting edge PHY techniques, there is a need for network-controlled MAC features with management capabilities which could be further engineered to provide performance guarantees close to cellular radio access technologies, with a significantly lower cost, and ubiquitous availability. It is, thus, imperative that we visit these issues and understand the impediments for greater Wi-Fi success in the future.
In this session, we expect to bring together users, the industry, standards bodies, and academic experts to discuss and debate the above technical issues, aiming to understand how Wi-Fi technologies can continue to be effectively deployed for current and emerging applications for many decades to come.
