Triband RF Transceiver

 

 

Wireless testbeds provide the experimental facility to test the validity of algorithms and also to test different wireless system setup/configurations. In order to support the investigation into the Heterogeneous Wireless Access Network Research Testbed (HWANRT), we are currently designing and developing a triband RF transceiver.

 

Goal:

 

Design, build, and test a portable wireless transceiver board capable of operating at the following three ISM bands,

Transceiver testbed versus off-the-shelf transceiver blocks:

 

The developed testbed has several advantages over off-the-shelf transceiver blocks including, but not limited to:
