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

HetNets and small cell indoor deployments are an effective mean 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…

PIM testing: best practices in a nutshell

When it comes to PIM testing, the necessary steps to identify passive intermodulation (PIM) and locate its source are similar to interference hunting. In the end, PIM is an internal source of interference and can have a significant impact on network performance. Before starting with PIM measurements, however, it is recommended to test return loss. The PIM analyzer transmits high power;…
