Singapore Telecommunications' unit Optus on Thursday said it acquired a variety of new metropolitan licences for its customers in the 2300 MHz and 3500 MHz spectrum bands.
Optus, which provides telecommunications services for individuals and businesses in Australia, won two 2300MHz lots in Sydney and Melbourne, and three 3500MHz lots in Sydney, Brisbane and Adelaide for A$6,513,000 (S$6.7 million).
The 3500MHz band, globally harmonised by the International Telecommunications Union (ITU), is recognised as the 5G pioneer band and its acquisition complements Optus' 3500MHz metro holdings, it said in a regulatory filing.
"This acquisition of new spectrum assets in the 2300 and 3500MHz bands ensures we are future proofing our network to meet our customers' increasing data demands," Optus Networks Managing Director Dennis Wong said in a statement.
The Optus 4G mobile network reaches 96.5 percent of the Australian population. Optus is the most significant financial contributor to the Singtel Group, Asia's leading communications group.
