Design of embedded wireless network camera

摘要

Wireless fidelity (Wi-Fi) is one of the most popular network technologies today. It is widely used in consumer electronics, industrial control and network monitoring. In this paper, we will introduce a real-time wireless image transmission system. This system is based on Wi-Fi module, ARM, and using the Linux operating system controls the wireless transceiver. In our system, we transmit images with variable size. The data rate of the system is 3Mbps at least and 15Mbps at most. The Wi-Fi module uses infrastructure mode network of IEEE802.11. The camera transmits data and command with PC through the wireless router.
