We carried out the intercomparison ex- periments between VLBI and other techniques to show the capability of VLBI time and frequency transfer by using the current geodetic VLBI tech- nique and facilities as the summary of the exper- iments that we carried out since 2007. The re- sults from the two different types of experiments show that the VLBI is more stable than GPS but is slightly noisier than two new two-way techniques (TW(DPN), ETS8(TCE)), and VLBI can measure the correct time difference as same as ETS8(TCE).
