▁The ▁O E CD ▁calculated ▁that ▁there ▁were ▁ 1 . 2 7   b ill ion ▁total ▁mobile ▁broad band ▁subscri ptions ▁in ▁ 2 0 1 6 , ▁ 1 . 1 4   b ill ion ▁of ▁these ▁subscri ptions ▁had ▁both ▁voice ▁and ▁data ▁included ▁in ▁the ▁plan . ▁ ▁In cre ased ▁broad band ▁spe eds ▁▁ ▁Broad band ▁is ▁what ▁connect s ▁Internet ▁users ▁to ▁the ▁Internet , ▁thus ▁the ▁speed ▁of ▁the ▁broad band ▁connection ▁is ▁directly ▁correl ated ▁to ▁IP ▁traffic ▁– ▁the ▁greater ▁the ▁broad band ▁speed , ▁the ▁greater ▁the ▁possibility ▁of ▁more ▁traffic ▁that ▁can ▁traverse ▁IP ▁networks . ▁C is co ▁estimates ▁that ▁broad band ▁spe eds ▁are ▁expected ▁to ▁double ▁by ▁ 2 0 2 1 . ▁In ▁ 2 0 1 6 , ▁global ▁average ▁fixed ▁broad band ▁reached ▁spe eds ▁as ▁high ▁as ▁ 2 7 . 5 ▁M bit / s ▁but ▁are ▁expected ▁to ▁reach ▁ 5 3 ▁M bit / s ▁by ▁ 2 0 2 1 . ▁Between ▁the ▁fourth ▁quarter ▁of ▁ 2 0 1 6 ▁and ▁the ▁first ▁quarter ▁of ▁ 2 0 1 7 , ▁average ▁fixed ▁broad band ▁spe eds ▁glob ally ▁equ ated ▁to ▁ 7 . 2 ▁M bit / s . ▁South ▁Korea ▁was ▁at ▁the ▁top ▁of ▁the ▁list ▁in ▁terms ▁of ▁broad band ▁spe eds . ▁In ▁that ▁period ▁broad band ▁spe eds ▁increased ▁ 9 . 3 %. ▁ ▁High - band width ▁applications
