Application of Land infrared thermometer in temperature measuring of moving strip;

he edge cracking recognition and minimum width measurement of a moving steel strip are discussed.

Based on the development of mobile broadband multimedia communication system(MESH),metro train can use multifunction on one plate,such as real-time video monitoring,emergency communication,living broadcast and mobile IP.

COFDM technique is highly suitable for mobile broadband transmission because it can combat the inter-channel interference and multi-path fading effectively and has high spectrum utilization.

This artical firstly describes the development course, characteristics and the status in quo of HSPA and WiMAX; then discusses the competition and cooperation between HSPA and WiMAX; At last analyses the development perspective of next generation broadband mobile communication technologies.
