Professional career Haug worked at the Ericsson group in Stockholm and with Westinghouse in Baltimore, Maryland, USA, primarily on radio projects. In 1966 Haug joined the Swedish Board of Telecommunications where, together with Östen Mäkitalo and lead the joint Nordic project for cellular communications called the Nordic Mobile Telephone (NMT) system. NMT was an analog mobile phone system commercialized in 1980 in Saudi Arabia and throughout the Nordic countries through 1982, reaching 1 million subscribers in 1990. The NMT system enabled roaming among countries and lead the way to the common European System (GSM). Thomas Haug chaired from 1981 to 1992 the steering committee of experts that standardized the GSM system, first at the CEPT and from 1988 at the ETSI. Haug's personal contributions included introducing features such as SIM cards and SMS messaging. Haug remained chair of the standards work through 1992 when GSM was introduced to the market. GSM and its progeny (UMTS and LTE) is the world's leading mobile air interface with networks operating in more than 220 countries. He, along with Philippe Dupuis received the James Clerk Maxwell Medal in 2018. Prince William presented the award to them in Edinburgh for their contributions to the first digital mobile telephone standard.

Death Haug died in Sollentuna, Sweden on 9 December 2023, at the age of 96.

Awards Haug received, together with Mäkitalo, the Gold Medal of IVA (the Royal Swedish Academy of Engineering Sciences) in 1987.
