# 5G Tools for RF Wireless

Tools from engineers for engineers

# Antenna Horizontal Isolation Calculator

https://extapps.commscope.com/calculators/qhisolation.aspx

A tool to calculate Horizontal Isolation, distance between two antennas of different or equal frequencies. The calculator provides an estimate of the isolation provided by two horizontally separated antennas.

# PIM Calculator

This Tool will make your life easy while calculating and analyzing PIM (Passive Inter-modulation) in your DAS solution.

# 4G Theoretical Throughput Calculator

4G Theoretical Throughput Calculator Calculate the maxium theoretical throughput of a specified LTE Configuration. Supports TDD, FDD and SDL, Carrier aggregation and MIMO.
