tiaccess Edge Computing) can be used if low latency is needed and/or the transport capacity is limited. MEC can be divided into core, edge, and even to far edge like uMEC in the 5G light poles. For private networks of factories or harbors, completely new transport networks are needed, but the investment is not huge as only a couple of gNBs are needed in the limited factory area in a typical case. For ultra-reliability, protected transport links are used. For city networks with mmW gNBs, a complete new transport network is needed, and the cost may be huge. One solution is to use light poles for sites and create a shared net- work together with mobile operators and a city. In this case, only one shared transport network is needed. The needed transport capacity is bigger than just the traffic from gNBs since typically IoT (Internet of Things) traffic from the smart light poles are using the same transport. The city with a need to boost the digital ecosystem in the city area may share the costs of sites and fiber transport. The city anyway needs a network for the sensors and cameras to meet the UN (United Nations) sustainable development goals (SDGs) in the future (see [1]). Combining multiple networks into a single one benefits mobile operators as well as the city. Indoor networks have only a limited possibility of using existing LAN (local area net- work) networks. Quite often, there is not enough capacity technically available, but the new multi-Gbps LAN technology enables at least the low end of 5G capacities. Other- wise a new transport network is needed. IAB can be used to connect those gNBs that have LoS to each other. Window CPE (Customer Premises Equipment) can be used to get the signal from an outdoor gNB. 9.1.3 Own versus Leased Transport Transport network strategies are often broadly categorized into two, according to whether the mobile operator owns and operates its own transport network, or whether the transport links are leased from a third party connectivity service provider. Traditionally, incumbent
