Front haul requirements
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
• 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
