Hi there,
As LTE-Cell-Scanner doesn't support TDD mode:
https://github.com/Evrytania/LTE-Cell-Scanner
I fork LTE-Cell-Scanner and add TDD support to it:
https://github.com/JiaoXianjun/LTE-Cell-Scanner
(Not reviewed by James Peroulas, so it is just experimental currently.)
It works fine with rtl-sdr E4k tuner dongle below 2.2GHz, but doesn't work
in 2.5~2.7GHz even with external MMDS-LNB.
Because the algorithm assumes analytic relationship between carrier and
sampling frequency error.
I write some matlab scripts (
https://github.com/JiaoXianjun/rtl-sdr-LTE )
to separate carrier and sampling processing in algorithm. Aided by
MMDS-LNB, the scripts can detect TDD&FDD LTE cell in 2.5~2.7GHz now!
12 LTE Cells information are decoded. 2 are FDD LTE, the rest are TD-LTE.
Because here is China! (Partly because that TD-LTE is announed earier than
FDD by government)
Hope that in the future these features can be merged to original
LTE-Cell-Scanner.
Scanning results and video are attached.
