If you use Cloud RAN/Remote Radio Heads then you need the full compressed radio signal using CPRI (up to 3.5Gbps per sector). Analog DAS may need even more. So sites with a few sectors and/or carrier frequencies could use anything up to 20Gbps. That generally means (dark) fibre, whereas a small cell can be connected using copper or one of the many wireless backhaul alternatives via standard Ethernet. The term Fronthaul is often used to distinguish this much higher CPRI data rate to the remote radio heads.David Chambers (via Small Cells World Series Linkedin group)noreply@blogger.comtag:blogger.com,1999:blog-7068042310767317158.post-68891438293752009662014-11-03T11:07:31.284+00:002014-11-03T11:07:31.284+00:00Really curious about 10Gbps "Backhaul" r...Really curious about 10Gbps "Backhaul" requirements?
