    Ten Cues You Need A 5G MIMO Channel Modeler

    How does Wireless InSite differ from planning tools?  The most important differences emerge when users need to simulate 5G mmWave and MIMO systems.  This paper presents ten cues that your organization may need a channel modeling tool like Wireless InSite to supplement your 5G network planning efforts.

Antenna Factor Concepts

An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.

Shielding Effectiveness Test Guide

Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.

Marines' “Mega Drone” Illustrates Need For High-Efficiency Microwave Power Modules
