Biography of Sing H. Lin, Ph.D., E-Mail:

Author of this Travelogue Website is Dr. Sing H. Lin, 林星雄 博士

Dr. Sing H. Lin is a retired Telecommunication engineer and manager with technical expertise in the area of radio/wireless communication technologies and systems. He received his Ph.D. Degree in electrical engineering from University of California at Berkeley, California, USA in 1969 and his B.S. Degree in electrical engineering from National Taiwan University in Taipei, Taiwan in 1963. He joined Bell Laboratories in 1969.

He had been a member of the US Delegation to International Telecommunication Union (ITU) for many years in developing global standards and recommendations for radio/wireless communications systems including Third Generation (3G) mobile wireless communications systems and beyond. In 1998, the international team of wireless technology experts, including Dr. Sing Lin, completed the development of ITU standard for 3G mobile wireless communication systems. This 3G wireless mobile communication system standard provides the platform that spawned the rapidly growing industry of very popular smartphones with many useful applications attracting huge number of users all over the world. The smartphone industry has moved forward into the international 4G system standard which is also known as LTE (Long Term Evolution) and will be moving into 5G system standard in the near future.

He has 35 years of experience in research and system engineering work on terrestrial and satellite based wireless access and radio communication technologies. He has presented and published 68 technical papers and talks in this field of wireless/radio communication technologies. He is a co-inventor with a patent on radio technology and another patent on Chinese Spelling Code (CSC, 中華拼字碼) which is important for efficient management of information based on Chinese language in modern Information Age. A list of his technical publications, patents and copyright certificate is at the following website:

In 1998-1999 time frame, Dr. Lin was a District Manager for Wireless Standards Management in AT&T Laboratories. From 1984 to 1998, he was the Director for Wireless Technologies in Telcordia (formerly Bellcore). From 1979 to 1984, he was a Technical Supervisor on Radio Technologies in Bell Laboratories.

Dr. Sing H. Lin and his colleagues in the old Bell Laboratories had conducted many years of experiments on effects of multipath radio propagation and rain attenuation on the performance of terrestrial and earth-satellite microwave communication radio links. Such experiments and huge amount of data were collected from numerous microwave radio links in USA and in some foreign countries such as Saudi Arabia. Results from such experimental data, analyses and developed theories are important for engineering microwave communication radio links to meet performance objectives. Some of these results were published in the following technical papers:

S. H. Lin, H. J. Bergmann and M. V. Pursley, "Rain Attenuation on Earth-Satellite Paths - Summary of 10-year Experiments and Studies," The Bell System Technical Journal, Vol. 59, No. 2, February 1980, pp 183 to 228.

S. H. Lin, "Statistical Behavior of Deep Fades of Diversity Signals," IEEE Transaction on Communications, Vol. COM-20, No. 6, December 1972, pp. 1100 - 1107.

By using statistical Theory of Extremes, Dr. Sing H. Lin developed a theory and a method to obtain nationwide long term (25 to 50 years) distributions of rain rate at more than 200 locations in USA. Such theory and method are published in the following technical papers:

S. H. Lin, "Statistical Behavior of Rain Attenuation", The Bell System Technical Journal, Vol. 52, No. 4, April, 1973, pp. 557 - 581.

S. H. Lin, "Rain Rate Distributions and Extreme Value Statistics," The Bell System Technical Journal, Vol. 55, No. 8, October 1976, pp. 1111 - 1124.

Dr. Lin is a Life Senior Member of IEEE (Institute of Electrical and Electronics Engineers), and a member of the International Scientific Radio Union (URSI). He was the President of Chinese Institute of Engineers-USA/Greater New York Chapter (CIE-USA/GNYC, 美洲中國工程師學會) in 1998 and 1999.

Dr. Lin is a recipient of IBM Fellowship at University of California at Berkeley, of Bellcore Award of Excellence, and of Institution Service Award of the Chinese Institute of Engineers – USA, Greater New York Chapter (CIE-USA/GNYC).

His tour and witness of the Shrink-and-Grow Mystery in the Mystery Spot near Santa Cruz, California in 1993 planted the seed in his mind to start thinking about and research on such strange phenomena on earth surface. His retirement in 2000 plus his long term scientific curiosity lead him into research on several strange phenomena at many Gravity Hills and Mystery Spots on earth as related to Dark Matter and Dark Energy which are the greatest mysteries in modern science. His preference of doing his own driving in his sightseeing trips (自駕觀光旅遊) enables him to take many short side trips to see and to experience some very strange phenomena in many Gravity Hills and several Mystery Spots on earth. (Note: Most commercial group tours do not visit such strange places of Gravity Hills and Mystery Spots.)

The results from his research for more than 20 years indicate that the strange phenomena at those Mystery Spots and Gravity Hills at special locations on earth surface are caused by very high concentration of dark matter at those special locations. In the decades since their discoveries, the strange phenomena of dark matter and dark energy in astronomy have inspired many theories, but none have satisfactorily explained either phenomenon. Scientists working on potential theory for dark matter need to take these strange phenomena on earth surface into account in addition to the strange phenomena observed in astronomy.

His strong interest in astronomy and science continues from his student life through his professional radio engineering life and into his retiree life. He is still enjoying research at the frontier of science on the great mysteries in nature and science.

After retirement, he has been enjoying his hobbies of research on science, traveling, sightseeing, wildlife watching, and photography. For the purpose of sharing such joy with his friends and many other people all over the world, he builds this Travelogue website (WWW.SHLTRIP.COM, 老林遊記) which has become very popular and has been attracting hundreds of accesses every day from friends and strangers all over the world.
