to whom it may concern:

　　 i am a senior engineer and the head of transmission business department of great dragon telecommunications group. as the instructor of him in his graduation fieldwork, i am very glad to write this letter in support of mr. xxx‘s application for studying in your university.

　　 i got to know mr. x in1998when i was the head of a research and development team on sdh optical telecommunications transmitting system, a part of the state863program. he was recommended to me as a top student of peking post and telecommunications university. after strict examinations, i accept him as a member of our team. although mr. x worked with us for only one year, his research ability, diligence, and team spirit really impressed all of us.

　　 mr. x has strong independent research and exploit ability. when working in our team, he was responsible for the research task of mapping four34mb/s signals into a stm-1. he creatively solved the problem of de-mapping and jitter restriction of pdh signals in sdh system. this research raised the transport efficiency of34mb/s signals by33% so as to meet users‘ higher demand. this technology successfully passed the test of the information industry ministry and was applied to the broadcasting and tv transmission experimental network of hunan province later.

　　 mr. x is proficient in english. he can communicate with foreign specialists in english, which is rare among chinese young people. i think language will not be an obstacle for his study and life abroad.

　　 telecommunications industry is a rising industry in china. chinese government is giving full support to its development. i support mr. x‘s decision, and hope that he will come back to make more contribution to our motherland after he finishes his program abroad. i would be very grateful if you could give his application your fullest consideration.

　　 yours sincerely,
