“Have you ever you have …”

This phrase sometimes precedes a story about a difficult or difficult experience. For Internet users all over the world, this may be a bell: Have you ever extinguished Wi-Fi on your phone to prevent calls from declining when leaving home?

Many people who read here can be associated with this scenario. Why this?

This is because the mobile devices tend to adhere to Wi -Fi (whether at home, in the office or anywhere else) for a very long time, and often turns into cellular when the time has passed. This can lead to audio calls and data connections that stop for 20 seconds or more. This “sticky” behavior has been present since mobile devices were combined into the first Wi -Fi and cellular radio devices.

The problem stems from a basic feature of mobile devices, which follows the “Wi-Fi First” approach. However, the problem is exacerbated due to the lack of a uniform mechanism to seamlessly move between the Wi-Fi network and cellular networks, making users vulnerable to disorders.

How does this affect the end user?

In the digital age today, we rely heavily on mobile devices for everything – from video calls, broadcasting services to work online and social interactions. However, many users face a frustrating experience: when moving between the Wi-Fi cellular networks, their devices are often struggled to maintain a stable connection, leading to decreased calls, hidden videos or lost data sessions.

This lack of smooth communication not only disrupts the user activities, but also affects service quality perceptions, which completely disrupts Wi-Fi or turns into less efficient networks.

How can we improve the experience?

In cooperation with member operators, Cablelabs works to describe the weak user experience that this problem creates and understands the extent of its occurrence.

Our field tests include hundreds of video calls for video calls, testing video recall applications and making audio calls via devices from manufacturers and operating systems. We evaluated the user experience based on vocal dropouts, video and freezers, and we dropped the calls, and we collected the results.

Our members have also analyzed hundreds of millions of Wi-Fi signal databases during the times when the Wi-Fi phones move to cellular networks. We have even made surveys with actual customers to collect visions in their experience when leaving Wi-Fi coverage.

What did we find?

A long short story, the problem is real. It is annoying for users and happens frequently. Our test sheds light on the extent of this problem as shown below.

Most of the devices we have experienced for long periods (usually between 19 and 54 seconds) of the bad sound, the sound and/or the frozen video were dropped during calls. Standard voice calls were only between 10 and 13 seconds of bad sound during the transition from Wi-Fi to cellular. From the recovered signal data index analysis provided by the RSSI, RSSI is low enough for the cause of problems with Wi-Fi voice calls 60 percent of the time when moving from Wi-Fi to cellular. When using other application problems, 40 percent of the time is likely to occur. About half of the users surveyed manually replaces their mobile devices between Wi-Fi and Cellular at least once a week, with 44 percent of these users who have problems while moving.

The result is clear: Without the non -welcoming network transitions, user experience, reliability decline and increased dissatisfaction.

While standards development organizations have made some developments, especially for the Wi-Fi network call, these solutions have not yet been addressed after the challenges of cumin and disruption during the network transfers of other applications.

What next?

This multi-faceted problem, given the various group of stakeholders-including devices sellers, operating system sellers (OS), sellers of a group of slices, and developers operators, each uses their own algorithms/main performance indicators to try to solve the Wi-Fi problem. The transition to cellular can once Wi-Fi begins to decompose to improve the user experience, but it will not completely solve the problem.

Cablebs is actively involved with all stakeholders in this field in an attempt to comply with a common and simplified solution aimed at enhancing the user experience. This will guarantee that we can face the challenges that users face today during network transfers in a consistent way, regardless of the user access network.

We are also working with industry sellers and standards institutions (such as the Wi-Fi Alliance) to test and develop solutions for non-welded communications that provide reliable and consistent experiences for users. If your company is a seller of mobile devices and wants to deal with Cablebs in this work, contact us to see how we can cooperate to achieve a smooth connection.

Wi-Fi Spectrum: 6 GHz Using is increasing and heading towards fatigue

glm9v — Tue, 20 May 2025 14:00:59 +0000

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.

Cablelabs is developing a white paper to exchange a detailed technical analysis above, including the basic methodology.

L4s in Wi-Fi: A way to smooth interactive experiences

glm9v — Wed, 26 Feb 2025 16:00:00 +0000

Modern networks provide impressive speeds – often reach Gigabits per second – however they still have unexpected delays that can disrupt interactive applications. Whether it is video conferences, cloud games or remote cooperation, these contradictions can lead to frustrating user experiences. While network operators seek to enhance reliability and response, a more effective solution is needed.

To address this need, the ITF (IETF) work group has identified an institution responsible for developing open internet standards – low productivity structure, low loss, and developable production engineering (L4S). L4s enables applications to implement a new mechanism to ensure that its data is sent as soon as the network can support, but not faster. The result is the use of the effective capacity with the minimum delay of the waiting list and the loss of low beams.

This shift to the most comprehensive service quality model (QOS) is necessary to provide smooth and uninterrupted performance through a wide range of services, from games and video to cloud computing and augmented reality.

What is L4s?

The L4S power stems from new congestion algorithms that adapt to new grains from crowding in the IP layer through different network elements along a comprehensive path (E2E). Although L4s can be published on each of the network elements, its most important effect is at congestion points, which are also referred to as network bottlenecks – where the rate of packets can exceed the rate of departure.

The cable industry has already adopted support for L4s, as part of the Docsis® 3.1 Low Contping specifications (it is also carried in Docsis 4.0 equipment as well). The operators began to enable this job in their networks, and it is expected to do more in the coming months. However, the BroadBand Access Sector is only a potential bottle neck. There are others on the E2E path.

The need for L4s in Wi-Fi networks

Wi-Fi networks, in particular, require L4S support because they are often congestion in E2E networks. In fact, although Wi-Fi networks often announce the maximum capacity of communications that exceed the wide range of bold, the actual performance is greatly affected by factors such as the distance between customers and access point (AP), as well as the number of APS and customers working on the same channel. This need to support L4S is more important given that a large part of the Internet traffic is transmitted via Wi-Fi.

WBA L4S implementation and NS3 simulation instructions

Wi-Fi offers unique challenges to implement L4S compared to wire technologies such as Docsis® networks. While wired networks see in the first place the delay of temporary storage only, the Wi-Fi network also provides delays to media access, which can be important in crowded environments. To deal with these challenges, Cablebs has worked within the comprehensive service quality working group in the wireless broadcast alliance (WBA) to produce a set of guidelines to implement L4s in current Wi-Fi products.

Covering guidelines:

L4S technology overview, explaining mechanics and its benefits. The importance of L4S support in Wi-Fi equipment to improve the performance of the E2E app. Implementation strategies for Wi-Fi equipment suppliers to enable L4S functions in their products. Simulation and test results that show L4s’s advantages in real world scenarios

Simulation results are based on the Wi-Fi NS3 model developed by Cablelabs, designed to evaluate L4S performance in Wi-Fi networks. The model is open source and is available for players in industry and research to support the deployment of L4s and evaluate its impact on various cases of use. In addition, Cablebs provided field test data conducted with Nokia AP.

L4S future in Wi-Fi

Today’s Wi-Fi equipment suppliers can take advantage of L4S implementation instructions to develop support on their current platforms (such as Wi-Fi 7). Several proposals submitted by industry leaders, including Cablelabs, aim to integrate L4S support into the Wi-Fi 802.11 standard, ensuring the original L4S support across the future generations of Wi-Fi.

In addition, with the maturity of the ecosystem, Cablebs will continue to improve the NS3 model to expand its application to apply on more scenarios and use of use. This continuous effort is developed in cooperation with the WBA E2E QOS working group.

L4S is a very important step in the development of the Internet that solves many problems that cause frustration today, as it seems that the frequency range alone has not fully enabled reliable and rapid interactive applications experiences.

To take this step completely, the network slices that are potential bottlenecks in residential publishing operations-the arrival network and the Wi-Fi–you need a compact support for L4s.

What is a heat map? A survival guide to installing network cabling and WiFi coverage

glm9v — Mon, 09 Dec 2024 14:08:51 +0000

In today’s world, a strong, reliable wireless network is essential for both business operations and daily tasks. Whether you work in a large corporate office, a warehouse, or even a residential space, understanding wireless signal strength and coverage is crucial. This is where the Wi-Fi heat map comes in. A heat map provides a visual representation of wireless signal strength across different areas of your property, helping to ensure your network is performing optimally.

Additionally, a heat map is critical in planning and optimizing network cabling installation, ensuring access points are strategically placed for best performance. In this article, we’ll explore what a heatmap is, why it’s recommended, and how it plays a role in your overall network cabling installation plan.

What is a heat map?
A heat map is a color-coded visual tool used to evaluate wireless signal strength and coverage. Also referred to as a Wi-Fi heat map, this visual representation helps you understand where your wireless network is performing well and where it’s lacking. The colors on the heat map range from green to red, with green areas indicating strong signal strength and red areas indicating weak or no signal coverage. Depending on the type of report and data you’re looking at, you may also see other colors such as blue to represent specific bandwidth measurements.

Data collected from a heatmap can include multiple metrics such as signal strength, data transfer rate, and the number of devices connected to the network. This comprehensive analysis provides the information needed to optimize your network’s performance, making it a vital part of your network cabling installation and wireless network setup.

Why is a heat map recommended?
When setting up a wireless network, many people make the mistake of randomly placing wireless access points (WAPs or APs) without understanding the actual signal coverage in the space. A Wi-Fi heatmap takes that guesswork out of the box by providing a detailed view of where your signal is strong and where it’s weak. This visibility allows you to identify areas that may need additional access points and helps you avoid installing equipment in areas where the signal is already optimal.

Wireless access points

Performing a heat map scan before installing network cabling also helps save time and money. Instead of overloading your network with unnecessary WAPs or running redundant cables to different parts of the building, a heat map allows for precise planning. This results in a more efficient network that meets your needs without redundancy.

How is a heat map made?
Conducting a Wi-Fi heatmap requires careful planning and implementation. To get started, you’ll need to provide Bridge Cable’s network cabling services team with a copy of

Your sitemap. This should include every floor within your jurisdiction, as well as any surrounding areas or buildings. The team will then carry the necessary equipment to orbit in space and collect data on radio signal strength.

During the walkthrough, the technician will follow a specific path designed to gather the most accurate information possible. This includes reaching areas that may be difficult to reach, ensuring that the entire property is covered. If you already have wireless access points, they will also be taken into account in the heat map report.

Once the data is collected, the results are compiled into a visual map, allowing you to see where your network is performing well and where it needs improvements. This information is critical when planning your network cabling installation, as it tells you where access points and additional cables should be installed to improve performance.

Internal and external heat maps
Conducting a Wi-Fi heatmap is a similar process whether the survey is conducted indoors or outdoors. The main difference lies in the equipment required for each environment. When planning an indoor network, the cables and access points used may differ significantly from those required for an outdoor setup.

For an indoor heat map, the primary concern is often navigating around obstacles such as walls, furniture, or other physical barriers that can attenuate the signal. On the other hand, outdoor environments may require more robust wireless access points and network cabling installations to withstand the elements. No matter the environment, the heat map will guide the correct placement of access points and cables needed to ensure comprehensive wireless coverage.

Understand areas of weak signal strength
One of the most valuable aspects of a Wi-Fi heat map is its ability to highlight areas with weak signal strength. There are many potential causes of poor signal performance, and understanding them can help you make informed decisions during network cabling installation.

Obstacles: One of the most common reasons for poor signal strength is obstacles. These can include anything from furniture to walls to shelving units. In particular, large buildings such as warehouses or factories often experience signal degradation due to obstacles blocking the wireless signal. Building Structure: The building structure itself can play an important role in signal strength. Materials such as concrete, metal, or brick can interfere with wireless signals, especially in older buildings. Identifying these problem areas through a heatmap will allow you to install additional access points when necessary. Insufficient access points: In some cases, weak signal strength is simply the result of not having enough wireless access points. The heat map will show you where more access points are needed, ensuring your network is adequately supported while installing network cabling.

How heat mapping improves network cabling installation
A heat map is more than just a tool for evaluating wireless signal strength; It also plays a crucial role in optimizing your network cabling installation. By identifying areas with weak signals or congestion, a heat map provides the visibility needed to plan more effective network infrastructure. This includes placing access points in ideal locations and running cables in the most efficient manner.

Installing a wireless access point

Using this information, network cabling companies like the Bridge Global Services team can design a network cabling installation plan that ensures consistent, high-quality wireless performance throughout your facility. Whether you’re dealing with a small office space or a large industrial complex, conducting a heat map survey is the first step in creating a robust network that meets your specific needs.

The Wi-Fi Heat Map is an essential tool for anyone looking to optimize their wireless network and ensure the success of their network cabling installation. By providing a clear, color-coded view of signal strength, a heat map helps you identify weak areas, reduce installation guesswork, and make informed decisions about where to place access points. Whether you work indoors or outdoors, performing a heat map before installing network cabling ensures that your network will be reliable, efficient, and tailored to your specific environment.
