CPRI over E-Band Test and Field Trial Proved RTN380
About SKT • SK Telecom(SKT) is the leading mobile operator in South Korea, 2011, SKT began to construct LTE network, June 2013, SKT announced LTE-A.
Lab Test
RTN380
Fixed Attenuator
• SKT chooses C-RAN for the LTE-A network coverage. • For speed up the LTE-A network deployment, E-band is chosen by SKT because of the large capacity and CPRI.
