Gazelle Quad Receiver System
Gazelle quad receiver system 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.
All products include standard 1 year hardware warranty.

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.

Gazelle Data Processing
Gazelle Data Collection Temporal
Does the Gazelle demodulate signals?
No. The Gazelle can scan for and power profile most popular wireless networks but it does not demodulate packets.
How fast can you drive when performing drive-study analysis using a Gazelle?
Gazelle measures up to 4 unique RF bands simultaneously at a rate higher than the recommeded 40 lambda allowing a driving speed of approximately 80 MPH.
Can I export Gazelle data into my favorite mapping program?
Yes. Gazelle supports a variety of post-processing software.
Can I use Gazelle in GPS-based drive-studies?
Yes. Gazelle is available with an optional, removable 12-channel GPS receiver and supporting software perfect for drive-studies.
