20 For 4G, front haul really means carrying CPRI A set of 1G to 10G interfaces not a problem: WDM-PON Simple calculation of wireless front haul for 5G Front haul requirements Typical backhaul capacity per sector for 4G ~100Mb/s 20 MHz of spectrum going to 200MHz: 1Gb/s 10x cell densification: 10Gb/s CPRI: 30 bits per sample vs. 4~5 bits of info: 64Gb/s 64x64 MIMO: 4Tb/s to serve the 100Mb/s area! Providing this bandwidth digitally seems prohibitive Many are now considering analog systems
