Sign up to view the price

Gazelle Quad Receiver System is a high performance 3G/4G/5G modular CW (Continuous Wave) 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 can support C-band, CBRS, 3.5 GHz and most other 3G/4G/5G (non-mm wave frequencies) RF spectrum.

Description

Gazelle Quad Receiver System is a high performance 3G/4G/5G modular CW (Continuous Wave) 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 can support C-band, CBRS, 3.5 GHz and most other 3G/4G/5G (non-mm wave frequencies) RF spectrum.

  • 4 swappable RF modules
  • High speed scanning 40 lambda receivers
  • Supports multiple wide bands and many frequencies

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. Gazelle can support C-band, CBRS, 3.5 GHz and most other 3G/4G/5G (non-mm wave frequencies) RF spectrum.

Features:

  • Multiple bands support including WiMAX, LTE, GSM, LMR, PCS, ISM, WCS, ACS & more
  • Quad modular receivers allow users to swap various 3G/4G/5G bands while in the field
  • Support for standard and 40 lambda averaging (post-processed)
  • Internal 12-channel/12 satellite GPS receiver with active antenna
  • Custom user-created channel lists
  • User selectable sampling rates and IF bandwidth
  • Captured data output via USB for connectivity to any PC
  • Optional GPS-based mapping Forecaster™ PC software support
  • Designed and manufactured in the USA

F.A.Q.

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.
