If your favorite team win they may use indoor positioning technologies

Today’s professional teams or large school team will use a variety of techniques to track the actions of players on the pitch, analyzing their performance. Mostly with camera recording everything that happens on the field, coaches from all angles playback, observation of details. There is now a new — –“real-time location system” (Real-Time Location Systems,RTLS), also known as the “indoor positioning technology”, to collect more accurate motion information. Application of this new technology in mobile phone positioning is important in the innovation process, is expected to change, including physical training niche market.

“Real time location system” is the key to beacon (also known as the “Locator”) and a label. Beacon was placed in venues around several fixed positions, cooperative track label move. According to the different sports, the label can be worn by athletes, or installed on a ball, or other device.

Just imagine after practice or a game, coaches and players will discuss the issue. How close can I hand stops the ball? How soon can I follow? Which defence jumped highest? Which players can hit the target? Vans phone case

As long as the use of precision positioning technology, all of these questions are answered. Training field the biggest challenge is how to indoor and outdoor to achieve the necessary precision but also keep track of equipment small and inconspicuous.

Shortcomings in the existing GPS

Using cell phone GPS knows, walking conditions, shows location is often related to the real location of several metres apart; driving when using a GPS, positioning is often several metres apart, but GPS software will assume that you are in the vicinity of roads so as to adjust your position. When you walk through a site or walk into a stadium, GPS difference more obvious.

Indoors, position accuracy becomes even worse. There are many solutions on the market, such as a shopping mall or an airport, but many of these systems can only be accurate to between five and ten metres. Such precision in the mall with enough, you can be sure to stand in front of the cafe, rather than a children’s clothing store. But on the field, a few meter is errors will make a great difference.

Shortcomings in the existing technology

If you are using Bluetooth low energy (Bluetooth Low Energy,BLE) technology can solve problems? If your site is installed on a heap of cheap, simple BLE beacons, when entering or leaving these beacons you can receive alerts. Unfortunately, this technology is sometimes not so sharp, and may take 20 seconds to respond. You know, lack of accuracy, time delay is the taboo of sports training.

Other wireless technologies? Such as the Bluetooth protocol, such as ultra low frequency phase difference technique. Unfortunately, these systems requires to label the players have to keep within sight of the Locator. If running in the field is packed with players, who can guarantee that moment fit without being blocked?

And when a real game, taking into account the hundreds of thousands of fans, practice is relatively “clean” radio environment is impossible. They will use mobile phones, 3G, Bluetooth and Wi-Fi mobile device, wireless signals are everywhere, these systems will be disturbed.

Solution of ultra-wideband radio technology

Ultra-Wideband (UWB) technology marks the precise tracking can be achieved, even if radio interference and obstructions is not affected, even dozens of signals or hundreds of the label also works.

Some companies are already UWB technology to market, for physical training. UWB interference can also send more accurate location and distance measurement. When narrow band radio signals or bypass the obstacle, at the other end will be received more than once which cancel each other out. UWB pulse signal sent shorter and clearer, even though there are obstacles or multiple path can remain the same. In addition, UWB systems on the refractive index of the position is measured in terms of signal, rather than the signal strength. This is very important because the signal strength is vulnerable to the effects of human interference and other, most radio-based positioning systems on the market are based on received signal strength measurements.

In short, the “indoor positioning technology” can fully meet the accuracy and speed of the athletes and coaches to sports requirements, meet Stadium radio environment.
