There can be several drivers for operators to build rural coverage. One reason is that end-users tend to select the operator that has the best coverage. Another reason is that governments often stimulate operators to extend their network coverage in sparsely populated areas.
A challenge for operators is to construct sites for rural coverage with solutions that make it economically viable to connect the unconnected. Ericsson has a complete portfolio with solutions like Psi Coverage and App Coverage Booster that maximizes the coverage and minimizes the total cost of ownership for rural sites.
