OCK Vietnam Towers Pte. Ltd. was established in 2016 and has since acquired Southeast Asia Telecommunications Holdings Pte. Ltd. ("SEATH") which is the largest independent base transceiver station ("BTS") operator in Vietnam. With the addition of SEATH, we have significantly grown our tower portfolio which contributes to the realisation of our vision to be an ASEAN tower infrastructure operator.
In Vietnam, OCK is the largest independent telecommunication tower company. As at end of 2018, the company through our subsidiary company, Southeast Asia Telecommunication Holding Pte. Ltd. ("SEATH"), owns more than 2,500 tower sites throughout Vietnam.
On top of leasing of BTS and tower space, SEATH also leases generators and provides 24/7 on-call/backup power service to telecommunication networks operators in the central and southern region of Vietnam. This service is essential for the operators to maintain uninterrupted network transmission for its mobile subscribers.
