Adaptive Wi-Fi provide three optimization algorithms to improve user’s experience.
- Network bearer switching algorithm
- Algorithm for automatically activating Wi-Fi
- Enhanced Power Saving
Network bearer switching algorithm
People connect Wi-Fi to use the Internet. Generally, the distance between the mobile device and the connected Access Point (AP) determines the speed of the Internet. For this reason, most mobile devices are programmed to base connection decisions on signal strength, which reflects distance. However, Wi-Fi connection is often maintained even when the Internet is not working, until the device completely loses the signal from the connected AP because of distance or obstacles which causes following pain points.
#1. Long loading times and frequent buffering can occur because of far distance between the user device and the connected AP. These problems may persist until the user manually disconnects Wi-Fi connection and enables cellular network, such as 3G or 4G LTE.
#2. Originally, a device automatically connects to an AP set provided by carriers even when the Internet is unstable. The user has to disconnect Wi-Fi and connect to Mobile Network to solve this problem.
-> The Internet should continuously work well without any user interference, such as manually disconnecting Wi-Fi.
Network switching algorithm on Adaptive Wi-Fi is the solution that maximizes the Internet coverage
- No more user interference
- Automatic switching the connection to the network which supports the Internet with intelligent calculating the status of networks.
In the figure below, the area marked with red is where Wi-Fi connection is maintained without Internet access. Network bearer switching algorithm on Adaptive Wi-Fi can effectively decrease the size of these areas.
Auto Wi-Fi: Algorithm for automatically activating Wi-Fi
People use Wi-Fi differently by location. In places where Wi-Fi is available, we turn on Wi-Fi because we do not want to be charged for mobile data. On the other hand, if Wi-Fi always on, we are subjected to frequent, unwanted connections and high power consumption.
To solve this problem, we introduce Auto Wi-Fi, which turns Wi-Fi on and off depending on your location. Auto Wi-Fi can make our customers care-free regarding Wi-Fi issues.
- What is Auto Wi-Fi
Auto Wi-Fi pays close attention to your connection patterns and remembers your favorite networks. It turns your Wi-Fi on when your favorite network is available. When you leave the area and the network becomes unavailable, Auto Wi-Fi will automatically turn off your Wi-Fi.
- Technical Details
Auto Wi-Fi uses geo-fence (virtual geological fence based on cellular stations) to detect user location. Depending user device’s location change in registered geo-fenced areas, events such as “ENTER” and “EXIT” will be triggered. Since this action is only triggered when actual events take place, device does not have to constantly scan its location, thereby saving battery life. Samsung’s original cell-based geo-fencing technique allows users to use Auto Wi-Fi without turning GPS on. Samsung’s geo-fencing technique also incorporates learning algorithms which improves location accuracy over time, as users continue to use this feature.
Enhanced Power Saving
Wi-Fi data usage on mobile devices has been growing at 67% CAGR, and almost 90% of mobile phone data is consumed over Wi-Fi. The increasing Wi-Fi traffic is generating demand for more advanced power saving techniques for longer battery life.
Currently used power save techniques attempt to reduce power consumption mainly for transferring large data files requiring high-speed throughput, such as movie and video files, through broadband Wi-Fi network. It may not be suitable for more widely used Wi-Fi applications, such as VoIP, Web Browsing, video and audio streaming, live broadcasting, gaming, and SNS.
– This is because legacy techniques does not consider the real usage of throughput, latency, and bit rate required for various applications and services.
To address problem, Adaptive Wi-Fi provides enhanced power saving
– Enhanced power saving technique can reduce power consumption while using various data services through Wi-Fi network.
– It enables lower power consumption by changing power save scheme based on real-time traffic pattern analysis during use of various network applications over Wi-Fi.
– This technique is compatible with WFA-certified APs.
- How it works
Enhanced Power saving technology keeps monitoring data traffic patterns and adaptively determines the optimal timing to enter power save mode and to wake up, in order to minimize current power consumption, without degradation of the quality of service, such as throughput and latency performances.
It can offer an intelligent, real-time analysis of data transaction over Wi-Fi, including the bit rate, frequency and interval of Tx and Rx packets.
Enhanced Power saving can reduce power consumption up to 50% - 75% for user applications offered through Wi-Fi network.
