This Station also trained required personnel, and provided Signals detachments at RCyAF formations. This was later shifted to SALF Base Ratmalana and renamed as Electronics& Telecommunications Wing. On 16th January 1993, the Advanced and Specialized Trade Training School was relocated to Ekala from Katunayake. This staion is commanded by Group Captain Muditha Mahawattage.
