Owing to its promising spectrum utilisation efficiency, large scale antenna system (LSAS) has been identified as one of the key technologies for fifth generation wireless networks. It will be more beneficial when combining LSAS with multi‐band radio for further boosting the network capacity and data throughput. However, this concept dramatically increases the system complexity and cost because of the architectural requirement of many multi‐band RF transceivers. It may even block the way of deploying this technology in the field. Practical multi‐band LSAS architecture is presented, by using newly introduced open‐flow like signal switch unit, the proposed architecture will be physically able to re‐configure its operation modes and to flexibly expand the system seamlessly regarding both RF part and digital part. To proof of concept, a simplified dual RFDAC‐based multi‐band radio transmitter with an FPGA‐based signal switch and an easyto‐use MATLAB‐based graphic user control plane is created.
