Early 5G (low frequency networking):
Single frequency base station: 3 Cells, 6-core fiber
Dual-band base station: 3 Cells, 12-core fiber
3G / 4G / 5G co-site: accumulation of required fiber resources
5G maturity (high frequency networking or low frequency increase point):
Optical cable consumption is amazing, need to add more fiber resources
Challenges of 5G fronthaul:
(1) 5G fronthaul networking and future expansion have huge demand for fiber cores
(2) The fiber resources between the current network DU and AAU are already very tight
(3 The re-laying of optical fiber not only has a large amount of engineering, but also has a huge cost in some urban areas that lack pipeline resources.
(4) How to use existing optical fiber resources to quickly complete wireless deep coverage is a problem that must be solved in network construction
