Propagation Prediction Analysis
4G Unwired can model several types of LTE predictions, dependent on outdoor vs indoor CPEheights, equipment specifications and building types (wood, brick or reinforced concrete). 4GUnwired can adjust the propagation models for greater accuracy with client data, extremelyuseful for additional system expansion.

4G Unwired Provides LTE PCI Planning for Improved Network Performance
In LTE networks, Physical Cell Identity allocation (PCI) is crucial for bothsubscriber Quality of Service (QoS) and data throughputs. Correct PCIplanning is an essential parameter in your network and is affected eachtime you add a new location. 4G Unwired engineers can provide fast andcost effective PCI plans once we have your network modeled in ourpropagation software.
