Thailand is located in the centre of mainland Southeast Asia, with income levels in the middle of the regional group.  Its level of human development, including income, life expectancy and education, is very high.  Thailand shares these features with Malaysia alongside similar proportions of urban and rural population, so the two countries are analysed as a cluster represented by Thailand. The chapter outlines the geographic, economic and social conditions for broadband connectivity in Thailand. It proceeds by examining the performance and structure of the market and reviewing Thailand’s communication policy and regulatory framework, including broadband strategies and plans. It then reviews competition, investment and innovation in broadband markets; broadband deployment and digital divides; the resilience, reliability, security and capacity of networks; and the country’s assessment of broadband markets. It offers recommendations to improve in these areas, which could be relevant for the other countries forming this cluster.
