Smart home UWB module

Smart home UWB module module indoor positioning UWB technology is a new generation of connection technology with ultra-precise positioning. UWB stands for Ultra Wide Band, which is ultra-wideband communication. A mobile phone that supports UWB technology can realize centimeter-level positioning of smart devices. It perceives the spatial position like the human eye. It can be directly controlled by pointing to any smart device. The angle measurement accuracy can reach ±3°, just like the high-precision version of "Indoor GPS".

Centimeter-level precise positioning in the living room

UWB technology is a new generation connection technology with ultra-precise positioning. UWB stands for Ultra Wide Band, which is ultra-wideband communication. A mobile phone that supports UWB technology can realize centimeter-level positioning of smart devices. It perceives the spatial position like the human eye. It can be directly controlled by pointing to any smart device. The angle measurement accuracy can reach ±3°, just like the high-precision version of "Indoor GPS".

This new technology can accurately perceive smart devices. When the mobile phone is pointed at the smart device, the control interface can be called out, and the TV can be directly cast to the screen with one finger. In the domestic smart home field, a revolutionary point-to-interaction method has been realized, which is another major improvement in experience.

UWB positioning advantages

(1) High positioning accuracy: UWB has a wide bandwidth and strong multipath resolution capability, able to distinguish and eliminate most of the influence of multipath interference signals, and the positioning accuracy reaches centimeter level

(2) Time stamp accuracy is high: the bandwidth of the ultra-wideband pulse signal is in the nanosecond level, when the position is calculated from the timing, the error introduced is usually less than a few centimeters

To achieve this function, mobile phones and smart devices need to have built-in UWB chips and array antennas. With the help of self-developed antenna arrangements and algorithms, precise spatial positioning can be achieved. UWB technology is different from the existing narrow-bandwidth communication systems. It has an ultra-large bandwidth of 500MHz to transmit information and improves the positioning accuracy to the centimeter level. This technology has also been used in the field of radar.

In addition, UWB technology also has safety performance. Thanks to UWB's ultra-wideband and narrow pulse characteristics, it is extremely difficult to be intercepted in space. At the same time, it has the blessing of distance algorithms to form a double insurance. These characteristics also have a broad imagination in practical applications. In the future, UWB technology will form complementary advantages with Bluetooth and Wi-Fi to meet users' wireless connection needs in different scenarios.

Revolutionary point of interaction

Magic modified mobile phones and a series of smart home devices, added UWB technology, and took the lead in realizing a revolutionary way of pointing interaction. Point the mobile phone at the smart device to control with one finger and send with one finger.


Point the phone to the fan and control the card to automatically emerge

One-finger control: Pick up the phone, point it at the smart device, and the control interface will pop up automatically. Turn on the TV, desk lamp to color, select songs and view lyrics, you can get it in place with one finger.


The mobile phone turns to the TV to control the card to switch automatically

One-finger delivery: In any interface of the mobile phone, aim at the smart device to perform gesture operations, and the current screen can be automatically delivered to the TV, touch screen speakers, notebooks and other smart devices.
