Propagation Prediction Analysis

4G Unwired can model several types of LTE predictions, dependent on outdoor vsindoor CPE heights, equipment specifications and building types (wood, brick or

reinforced concrete). 4G Unwired can adjust the propagation models for greater

accuracy with client data, extremely useful 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 both subscriber Quality

of Service (QoS) and data throughputs. Correct PCI planning is an essential parameter in

your network and is affected each time you add a new location. 4G Unwired engineers

can provide fast and cost effective PCI plans once we have your network modeled in

our propagation software.

8

Use Case: Shown below is WISP that had interference and throughput

issues with their existing network. 4G provided a corrected PCI plan

and significantly improved the network throughputs and coverage Red

is bad – Green is Good!

Given PCI Planning by Client

Red shows interference and

lower throughput
