Since the US policymakers and global policy makers are discussing the future of the spectrum policy, Cablebs exports preliminary results to analyze the use of Wi-Fi, which also confirms the decisive need to maintain current unlicensed spectrum resources and add more soon.
In short, the 6 GHz-the main frequency range of the Wi-Fi network, along with the Legacy 2.4 GHz and 5 GHz-is witnessing an explosive growth and high dependence that is expected to accelerate greatly this year. As a result of the rapid growth of consumer data and expected devices requirements over the next five years, the 6 GHz domain is rapidly approaching in high -density environments.
The 6 GHz spectrum will determine the Wi-Fi connection
Without more unlicensed spectrum in the pipeline, the current fully use of the current Wi-Fi will lead to a deterioration of performance, applications and services that depend on Wi-Fi as the backbone of modern communication.
Any proposals to reduce or re-display unlicensed spectrum 6 GHz will be devastating to the performance of the Wi-Fi network and seriously harm consumers, hardware manufacturers in the United States, and other companies that expect and rely on reliable communication. The failure to set an unlicensed spectrum to support the increasing use of Wi-Fi will lead to the experience of consumer’s deteriorating Wi-Fi performance.
These conclusions are based on a strict mesh simulation of a multi-storey residential environment, using a high-capacity NS-3 modeling tool that includes the specific parameters of Wi-Fi technology and user behavior. This analysis depends on the previous Cablebs work to clarify the need for an additional Wi-Fi spectrum, which we discovered in two recent publications of the blog:
This work now goes further to the design of the full Wi-Fi environment in a multi-storey residential building where a large number of customer, users and networks work close to.
Specifically, the study designed a 12 -storey residential building (for example, apartment or apartment building) with 12 units per floor. We included each Wi-Fi 6 GHz access point and an active client device (for example, smartphones, laptops, tablets, TVs and other connected devices) in the building. In simulation, 6 GHz is used, specific channels are set and the channel’s frequency range is randomly, while avoiding adjacent units on the same channel. The starting point for the growth of the device and the growth of traffic was based on the distribution of the typical homes connected today.
Then the study increased the number of devices and traffic peak over the coming years in line with industry expectations.
Simulation at work
To determine the Wi-Fi spectrum exhaustion, the study analyzed the main indicators of the (delay of transportation) and the loss of packages (lost data) through each device connected to each housing unit during the periods where the Wi-Fi activity is higher. Tarecy is a strong indication of the quality of service and the user experience for many famous and basic applications, including actual time connections such as face or zoom, media flow, online games, and home security. The loss of the package weakens all types of applications and is associated with reliability and congestion.
The results of the simulation show that consumers in dense residential environments are likely to suffer from a large-scale Wi-Fi performance deterioration, indicating the exhaustion of the spectrum in the short term on the basis of increased demand.
In particular, the study examined the performance of Wi-Fi within the 12-storey residential building on the basis of five years of increasing demand for Wi-Fi. In this scenario, consumers increased by about 30 percent of the construction experience simulator from the time of access to Wi-Fi in one direction-more than 10 milliliters (MS)-and the loss of packages by 2 percent or more. Since the time of arrival and the loss of packages exceed these thresholds, the quality of the resident will begin to decompose, especially for applications in actual time, such as video connection, which are more sensitive to Wi-Fi performance. With an increase in access time and loss of beams, even unrealistic applications, such as media flow, will begin in failure.
Below, the 1 and 2 Forms are the building of the building 144 units. Each rectangle represents a unit in the building. Figure 1 shows the specified units, their relative location in the building, and the amount of cumin for at least one customer device, 6 GHz in the unit after five years of growth in client devices and peak traffic. Figure 2 shows the same thing to lose the package. The difference in arrival time and the loss of packages through the building is a function of complex interactions between the devices within the unit and across the units, and varying numbers of client devices and the peaks of traffic in different units, and the difference in the spread of Wi-Fi signal within units and through units.
Figure 1: Cumin heat map (within five years)-a time of 90 percentage, which indicates units that exceed 10 milliliters at the time of reaching Wi-Fi in one direction and the amount of cumin for at least one device in those units.
Figure 2: Map of Pack loss (within five years) – units that exceed 2 percent of the loss of packages and the loss of the package for at least one device in those units.
The initial results show the importance of the 6 GHz spectrum in maintaining Wi-Fi reliability and its performance of American consumers and companies. In addition, the results emphasize the need for policy makers to customize more unlicensed spectrum. The failure to act would undermine the reliable Wi-Fi connection that enables consumers and American companies to access the high-speed broadband.
