Tongyu Communication Equipment Co., Ltd. is a high-tech enterprise engaged in research, design, production, marketing and service of mobile communication antennas. It was founded in 1996 and located at the Torch High-Tech Development Zone in Zhongshan City .In the ancient time, Zhongshan was called Xiangshan County. Zhongshan City is the hometown of Dr. Sun Yat-sen, the great revolutionary forerunner.Zhongshan city, a reputed city of the most suitable for inhabitation in China, covers an area of 1, 800 square kilometers with the population of 2, 6 million people.Zhongshan city is located at the center of Pearl Delta with Guangzhou in the North, Shenzhen in the East, Hongkong and Macau in the South. It has very convenient land and sea transportation and air freight. In the early ninetieth of 20 century, mobile communication in China just began to rise. At that time, as one of the primary equipment in mobile communication, the antenna market was monopolized by foreign products and antennas of foreign brands were sold with astonishing prices reaching 20, 000 RMB, equivalent to 2, 500 USD.The founder of Tongyu Communication, Mr. Wu zhonglin, was aspired to change the situation. He believed that whatever foreigners can do, Chinese people can do as well.In 1989, Mr. Wu zhonglin graduated from Xiâ??an Xidian University. Four years later, he began to research base station antennas which were used in simulated mobile network called TACS. After one year of hard research, the first base station antenna for mobile communication was created in China. In 1994, the antenna was first tested in the Zhongshan Mobile Communication Bureau of Guangdong City, and successfully passed the appraisal of national authorized institution.His success in this technology broke the monopolization by foreign products on base station antenna market in China, filled up one of the blank technical field in China, and forced foreign products to greatly lower the price from 20, 000 RMB to 6,
