Gazelle Quad Receiver System

Description

Gazelle is a high performance, modular receiver system that utilizes a high speed bus containing up to 4 independent receiver modules all simultaneously logging the RF energy needed to plot out coverage maps. Gazelle™ is designed from the ground up to provide hot-swappable receiver modules for in-the-field installation and includes an internal 12-channel/satellite GPS receiver. Gazelle's unique, modular high-speed receivers exceed the distance based averaging required to meet standard and 40 lambda averaging criteria essential for critical propagation analysis. The Gazelle is a low-cost test system ideal for advanced pre-buildout drive-studies for optimizing WiMAX and LTE networks.
