I have designed and implemented a Two Stage WiFi 5GHz to 10GHz XBand Communication System which allows the transmission of 5GHz IEEE802.11ac WiFi with bandwidths of 80MHz and 160MHz over XBand centered at 10.56 GHz. The center frequency can be tuned around 10 GHz. One application of this system is to do research on high throughput digital communication for the Amateur XBand (10-10.5 GHz) as well as deep space applications and point to point XBand links.

The design, building and testing of the Two Stage WiFi 5GHz to 10GHz XBand Communication System has been documented in the paper by Sasan Ardalan using the GNU Free Documentation License on the VIXRA preprint archive. Click on the icon below to get access to the paper in PDF format.

Here is the prototype of the system:

Here is the VSA results of two separate systems transmitting and receiving over 10.56GHz

Note the EVM around -30dB at 64QAM.

A page dedicated to XBand communication has been setup here which will provide more details.

As for why I chose VIXRA Preprint Repository. In a nutshell, I want to get the most detailed engineering document out to the public under an Open Source License, get it time stamped, and indexed by search engines. Don’t need a frikin endorsement since we already have all the credentials, See short biography here. Also, I was a Tenured Professor at NC State (Wolfpack!). VIXRA is no hassle and does not limit in any way publishing the work on other platforms. Hopefully we can get VIXRA to add Communications and Robotics to their categories.
