Cost-efficient Mobile Backhaul Network Design over TWDM-PON

Planning Cost-Efficient FiWi Access Network with Joint Deployment of FWA and FTTH

“…The proposed optimization framework offers details of FiWi network design, including the selection of PS's locations (out of the candidate locations of PPS and SPS), interconnection of all network devices, connectivity of users through fiber/wireless mode, and beam index for the wireless users. Next, we apply the minimum spanning tree (MST) algorithm [20], [21] over the optimization solution to incorporate the sharing of trenching and duct costs. We consider all gNBs transmit with the maximum power over all their RBs, i.e., P b,z,k = P max b,z,k ∀b ∈ B, z ∈ Z, and k ∈ K, where P max b,z,k represents the maximum transmit power of BS b for beam z over RB k.…”

“…(62) states that, the data rate demand of all users should not violate network (fiber) capacity. To consider the sharing of trenching and duct cost, we apply MST algorithm [20], [21] over the ILP output (interconnection of OLT, PPSs, SPSs and ONUs), and obtain the actual fiber layout and CapEx.…”
