It could be used as a traditional SDR device such as PlutoSDR or FMCOMMS2/3/4 with Xilinx evaluation board, and it also be used as hardware platform to support openwifi. 5*a348227fSXianjun Jiao 6*a348227fSXianjun Jiao<!-- 7*a348227fSXianjun JiaoThis README file will give the instructions about how to make the openwifi-hw project for antsdr in the [antsdr branch](https://github.com/MicroPhase/openwifi-hw/tree/antsdr) of openwifi-hw project. 8*a348227fSXianjun Jiao--> 9*a348227fSXianjun Jiao<!-- 10*a348227fSXianjun JiaoAbove should be unnecessary, because antsdr will be in the master in the future. 11*a348227fSXianjun Jiao--> 12*a348227fSXianjun Jiao 13*a348227fSXianjun Jiao## Work to be done 14*a348227fSXianjun JiaoThe antsdr has RF switch in the front-end, for now, the RF switch is fixed at a higer range, which will isolation the frequency below 3GHz and pass the frequency at 3GHz~6GHz. 15*a348227fSXianjun JiaoFor future work, it can add the rf swicth control in the devicetree, and this will change the rf switch with the frequency change. 16
