Abstract:
1. A wireless communication apparatus comprising: a wireless processing unit that performs wireless communication; and an application processing unit that executes an application, wherein the wireless processing unit comprises: wherein the wireless processing unit receives the wireless function update information when the wireless communication apparatus performs a wireless function update process, and receives data other than the wireless function update information when the wireless communication apparatus performs a normal data communication process, the wireless processing unit controls respective protocols defined in a physical layer (PHY), a data link layer, and a network layer from among protocols having the physical layer (PHY), the data link layer, the network layer, a transport layer, and an application layer to perform wireless communication, the update detecting unit of the wireless processing unit acquires an Internet Protocol (IP) packet that has been assembled after controlling the physical layer (PHY) and the data link layer from wireless signals transmitted and received using protocols of upper layers that are equal to or higher than the transport layer and detects the reception of the wireless function update information including a program and/or data that define the update process for updating the function of the wireless processing unit when header information of the Internet Protocol (IP) packet corresponds to a predetermined pattern that has been previously stored, and the update processing unit of the wireless processing unit assembles a plurality of the Internet Protocol (IP) packets of which reception of wireless function update information has been detected by the update detecting unit to generate the wireless function update information and performs the update process based on the generated wireless function update information to update the function of the wireless processing unit.
