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 the University of California at Berkeley, California, USA in 1969 and his B.S. Degree in electrical
engineering from the 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 the global standards and recommendations for radio/wireless communications systems including the
Third Generation (3G) mobile wireless communications systems and beyond. In 1998, this international team of
wireless technology experts, including Dr. Sing Lin, completed the development of ITU standard for 3G mobile
wireless communication system. This 3G wireless mobile system standard provides the platform that spawned
the rapidly growing industry of very popular smart phones with many useful applications attracting huge number
of users all over the world. The smart phone industry is now moving forward into the international 4G system
standard which is also known as LTE (Long Term Evolution).
He has 35 years of experience in research and system engineering work on terrestrial and satellite based
wireless access and radio communications 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 web page:
In the 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. Bergman 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 a Fading Signal," The Bell System Technical Journal, Vol. 50, No. 10,
December 1971, pp. 3211 - 3270.
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 has also 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.
S. H. Lin, "More on Rain Rate Distributions and Extreme Value Statistics," The Bell System Technical Journal,
Vol. 57, No. 5, May-June 1978, pp. 1545 - 1568.
Note: The technical papers in Bell System Technical Journal (BSTJ) from 1922 to 1983 are available online as
indicated in the following IEEE website:
A complete list of his 68 technical publications and presentations in various technical journals and conferences
and of his patents is in his web page at:
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 the 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
His tour and witness of the Shrink-and-Grow Mystery in the Mystery Spot near Santa Cruz in California in 1993
planted the seed in his mind to start thinking and research on such strange phenomena in Nature. His
retirement in 2000 plus his long term scientific curiosity lead him into research on Gravity Hills and Mystery
Spots 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
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.
He has been enjoying his hobbies of traveling, sightseeing, wildlife watching, photography, science research
and ballroom dancing. For the purpose of sharing such joy with his friends and 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.
