Embodiment Construction

[0026] next to Figure 1 Each part is explained. The device uses a set of baseband and radio frequency circuits. These two modules mainly realize the function of wireless transmission, and establish the wireless connection between the access device and the terminal and between the terminal and the terminal. U1 (Model ROK101007 from Ericsson Company) is used, which is a baseband and radio frequency module in dual-chip mode. The baseband chip is PMB99090, and the radio frequency chip is PBA31301 / 3. During specific implementation, the device can be placed outside the user's door, and only a very small (several centimeters) antenna enters the room. The design adopts embedded Linux operating system, U2 (MotorolaCodeFire5272 microprocessor) is used as the hardware platform, and the wireless communication protocol stack and upper layer application software run on the platform. The wireless communication protocol stack is a software stack developed by us in compliance with protocol ...
