RF Explorer support for WiFi Analyzer 5GHz band

We are happy to release RF Explorer firmware v1.12B31 with support for WiFi Analyzer feature in the 6G models: Download link.

Previous versions only supported WiFi channels in the 2.4Ghz range. This is immediately available for RF Explorer 6G, 6G Combo and WiFi Combo.

Covered channels and frequencies are listed below:

Channel number Center frequency (MHz)
36 5180
40 5200
44 5220
48 5240
52 5260
56 5280
60 5300
64 5320
149 5745
153 5765
157 5785
161 5805
165 5825

One problem we faced while developing the WiFi Analyzer for 5GHz is the large number of channels and lack of official standards. Therefore we selected the ones more frequently used so we can fit 13 channels in the LCD screen. A future option will allow to select a different configuration where less frequently used channels can be listed, too.

Known limitation: RF Explorer for Windows latest version available does not correctly interpret these channels, so this new firmware is intended for standalone use only. If you use it together with connected PC, frequency readings and channel numbers won't be correct. This will be resolved in an upcoming RF Explorer for Windows release in April.

Software update available

The new RF Explorer for Windows v1.12.1601.5 is available for download and includes very useful enhancements:

  • Tool Group for markers, easier and more convenient to use than menu. It has never been easier to place the marker you need!
  • Tool Group for visual options such as trace thickness or grid
  • Enhanced 3D Waterfall to support extended data resolution
  • Several bug fixes

This new version is fully tested and recommended for all users. For more details please check RF Explorer for Windows Release Notes

A new firmware version is also available for Signal Generator and Spectrum Analyzer:

  • Spectrum Analyzer firmware v1.12 Beta 26: fixes a problem where amplitude change from RF Explorer for Windows may be ignored sometimes
  • Signal Generator firmware v1.12 Beta 15: adds accurate power levels reading on screen. This is direct read from internal factory calibration tables stored in the device.

User manuals are also updated to cover new functionality available in firmware v1.12:

RFTrack for Android: TV Whitespace RF Explorer analyzer

Our friends at ICTP in Italy are presenting a global effort to record TV White Spaces in a worldwide database. These are RF frequencies formerly allocated by TV broadcast but not actually used. By detecting these whitespaces certain licensed and unlicensed transmissions can benefit from it. This project is using RFTrack Android app and a connected RF Explorer to capture GPS & RF activity, then uploaded to a global repository.

And this is all offered for free. As a community we can benefit from a global database with this information being timely updated. Contributors are appreciated: all you need is a RF Explorer and an Android device, record data from your local city and upload into the database.

The ICTP TVWS global database is available on this link:
