AIS, Thailand: A call for help

From rollout to rescuing the network in Thailand

Thailand’s leading operator, AIS (Advanced Info Service), chose Ericsson to upgrade its network from 2G to 3G. The rollout was scheduled for completion by the end of 2011. But despite careful planning and close cooperation with the operator, there were certain things that could not be planned for…

In Thailand, 2011 will be remembered as the worst year for flooding in the country’s history. Some 13.6 million people were affected, with 65 of Thailand’s 77 provinces so badly hit, they were declared disaster zones.

The floodwaters came fast, leading to a rapid shift in focus at AIS. The race was on to secure the operation of the network, so a business continuity plan was implemented immediately.

During the flooding, Ericsson worked on two fronts: carrying out the network upgrade in challenging conditions while securing essential communication services at the same time. This meant neither the victims of the flooding nor the rescue services were without the means to communicate at any point.


The challenge

To deploy a 3G network over 1,200 sites throughout Thailand during the worst flooding the country has ever experienced.
