Huge potential for next-generation IoT wireless connectivity standard

Cell phones are the most widely used electronic products, so the large-scale popularization of UWB must be inseparable from the support of cell phone brand manufacturers. In addition to the above-mentioned Apple action, in October this year, millet released a UWB-based "one finger" technology. As long as the cell phone is aligned with the smart home appliance equipment, the phone will automatically pop up the control interface of the device, the angle measurement accuracy of up to ± 3 °, do not need to point to open the control APP, eliminating the cumbersome equipment to find and pairing operations.

Of course, to realize these functions, it is necessary to have UWB chips and array antennas built into both cell phones and home appliances.

The digital key has been developed to the third generation, the first generation is based on NFC technology, but the user needs to put the phone close to the door handle to unlock the vehicle, the use of poor experience; the second generation is based on BLE Bluetooth technology, but Bluetooth in the positioning accuracy and information security has inherent shortcomings, there may be the owner of the vehicle close to the vehicle, the door can not be opened, and there is even a risk that the Bluetooth signal is intercepted.

Strong anti-interference ability, very high positioning accuracy, strong coexistence with other wireless signals, high security and many other advantages make UWB very suitable for digital car key application scenarios, and the sensorless opening door fits well with the brand positioning of intelligent and technological sense of the electric car.
