HetNets/Small cells: verifying indoor deployments (part 4 of 4)

HetNets and small cell indoor deployments are an effective means to deal with the exponentially increasing data consumption in mobile networks. After the careful planning and actual installation of a new small cell network, it’s time to verify the commissioned indoor deployments and ensure quality of experience (QoE). Both are best achieved with a commercially available smartphone, designed for reliable…
