The invention discloses a GMI sensor probe based on a ring-shaped amorphous wire and a preparation method thereof. The GMI sensor probe comprises a amorphous wire coil which is formed by winding the ring-shaped amorphous wire, wherein the amorphous wire coil comprises an amorphous wire section with the sensitivity to magnetic fields and an amorphous wire section losing the sensitivity to magnetic fields, and a signal acquiring coil is wound around the amorphous wire section losing the sensitivity to magnetic fields; The preparation method of the GMI sensor probe comprises the following steps of winding the amorphous wire into the ring-shaped amorphous wire coil, conducting heat treatment on a defined section of the amorphous wire coil so as to enable the amorphous wire coil to form the amorphous wire section with the sensitivity to magnetic fields and the amorphous wire section losing the sensitivity to magnetic fields, and winding and forming the signal acquiring coil around the amorphous wire section losing the sensitivity to magnetic fields. A processing shortcoming that the amorphous wire is hard to weld can be overcome, amorphous wire spatial reuse is achieved, and meanwhile only a mature heat treatment process in the material processing techniques is needed while plenty of complicated and immature amorphous welding is not needed.

The invention discloses an improved dual-band Femtocell (DBF) unlicensed channel access method to realize spatial multiplexing. According to relative distance between the DBF and a WiFi AP, the method has two situations: when the DBF and the WiFi AP are visible to each other, the method is simplified into an existing method, that is, the DBF and the WiFi AP occupies an unlicensed channel at different time, and all of DBF users in a DBF schedulable coverage range carry out data transmission; and when the DBF and the WiFi AP are invisible to each other, if the WiFi AP carries out data transmission with WiFi users in the coverage overlapped range, the DBF cannot take up the unlicensed channel, and if the WiFi AP carries out data transmission with WiFi users outside the coverage overlapped range, the DBF can take up the unlicensed channel and calls DBF users outside the coverage overlapped range to carry out data transmission. Compared with an existing DBF unlicensed channel access method, the method realizes maximized utilization of unlicensed frequency band frequency spectrum resources on the basis of ensuring WiFi system performance, and improves the system performance.
