The arrival of the fourth-generation (4G) wireless broadband service marks an important window of opportunity for the innovative mobile app market.
"Mobile users have an average of 30-40 apps on their phones and have them replaced when interesting apps come on the market," said C.R. Venkatesh, managing director and chief executive of Dot Com Infoway, an India-based organiser of the Global Mobile App Summit & Awards 2016.
The faster speeds of wireless internet connectivity will lead to opportunities for a range of mobile apps offering interactive games, video conferencing and streaming, location-based services, transport and banking.
With 60,000 mobile developers, Thailand's mobile app market is ranked third in Southeast Asia, only behind Indonesia and Vietnam.
Applift, a mobile app marketing platform, forecasts that Thailand's mobile games market will reach US$211 million this year and increase to $300 million in 2017, up from $93.5 million in 2014.
About 60% of revenue will come from mobile phones by 2017, up from 40% now.
"This makes Thailand the 20th-largest games market in the world," said Mr Venkatesh.
As of March 2015, Thailand's mobile penetration rate stood at 180%. About 75% of mobile internet users were aged under 35 and using apps for gaming, videos, music and e-commerce.
Mr Venkatesh suggested Thai mobile app developers focus on monetisation, noting localisation is a key success factor for developers.
Developers should also offer customers local payment methods on mobile devices, he added.
At least 60% of apps' revenue comes from advertising.
To capitalise on Thailand's rising mobile app opportunities, Dot Com Infoway is holding its mobile app summit in Bangkok this month, outside India for the first time.
The event will take place at the Sheraton Grande Sukhumvit hotel on Jan 22, aiming to provide updated information about the industry from international speakers.
Nuttaputch Wongreanthong, vice-president for online marketing of Total Access Communication Plc, said apps such as chat and video calling, games, photography, video and music streaming would gain popularity in Thailand this year.
Other apps will include temperature and humidity sensors and health-related apps that will help users stay fit and healthy.
Mr Nuttaputch said marketing strategy would be a crucial factor for developers to reach target audiences, as there are up to 1.5 million apps in Apple's App Store and 1.6 million in Google Play.
Global IT research firm IDC said Indonesia, Malaysia, the Philippines, Thailand and Vietnam were the five fastest-growing markets in Southeast Asia in terms of both app downloads and revenue in 2014.
Thailand is the second-largest smartphone market in the Asean region, while it is also among the top 20 in app revenue in the world.
In Thailand, revenue generation through mobile content and apps reached $600 million in 2014.
