Microsoft appears to be working to improve next-generation two-in-one products such as the Surface Laptop and Book series, according to a new patent application. In the same patent application, released earlier this week, Microsoft also revealed that it would improve the serviceability score of its products.
In its application document, Microsoft states that the components of the device can be replaced with a different housing material than the original housing material to improve the repairability and/or customization of electronic devices. The replaced housing assembly may have a different material than the original housing material. For example, electronic devices with housing recesses can be repaired by replacing the aluminum backplate of the housing.
Microsoft patents state that if parts of the housing are replaced with different materials, the signal strength of wireless adapters such as Wi-Fi will change. To improve service score and Wi-Fi performance, the company’s patent proposes a way to control wireless communication performance in electronic devices, including access to material characteristics data that contains a variety of materials, sending the first test signal on the first transmission channel at the first transmission channel, and then using the second antenna in the second position of the electronic device to test the signal on the first transmission channel. Based on the measurement attenuation of the first test signal received by the second antenna, it is determined that the housing material of the electronic device involves a variety of materials and adjusts the transmit power in the first antenna and the second antenna based on the material characteristics of the housing material.
