A digital printing device, comprising a suction transport means (). The suction transport means () comprises a transport belt () used for transporting a sheet material. At least one first suction box (), which is used for sucking the sheet material on the transport belt () by means of negative pressure during transport, is provided in the space defined by the transport belt (). Multiple first suction holes in communication with the first suction box () are provided on the transport belt (). At least one side of the first suction box () is provided with a movable door () which moves in a direction perpendicular to the transport direction to make the first suction box () fit the sheet material to maintain a negative pressure state. Using the transport belt () during printing, the digital printing device avoids the problem of poor registration accuracy, and improves the printing effect.

The disclosure discloses a method and system for switching wireless devices in a looped network. The wireless devices include a core wireless device and remote wireless devices, and the core wireless device and two or more remote wireless devices, connected through two ports of the core wireless device, constitute a looped network; the method including: when the core wireless device detects that a line error rate at each of the two ports is within a determined threshold range, the core wireless device sends a valid control character, otherwise, the core wireless device sends an invalid control character; wherein the valid control character sent at one of the two ports of the core wireless device is different from that sent at another of the two ports of the core wireless device; when the remote wireless device detects that a line error rate at a receiving end of a master port of the remote wireless device is within the determined threshold range, the remote wireless device forwards the valid control character received at a slave port to the master port, otherwise, the remote wireless device sends the invalid control character to the master port; and the remote wireless device sends the invalid control character to its slave port continuously. With the present disclosure, the stability of the networking mode through the RRUs is promoted.

The present invention provides a method for realizing compatibility between a WCDMA system and a GSM system, including: in the downlink data path of a base station, In-phase/Quadrature (IQ) data of the GSM system are mapped to the Common Public Radio Interface (CPRI) according to a predetermined rate before IQ data interleaving and framing the CPRI Base Frame (BF), and then the mapped data of the GSM system are de-multiplexed with IQ data of the WCDMA system; in the uplink data path of the base station, IQ data in the CPRI are de-multiplexed after de-framing and IQ data de-interleaving CPRI BFs, and then the de-multiplexed IQ data of the GSM system are de-mapped according to the predetermined rate. The present invention further provides an apparatus for realizing compatibility between a WCDMA system and a GSM system. The method and apparatus genuinely realize the compatibility between the WCDMA system and the GSM system by unifying two different radio transmission modes between the WCDMA system and the GSM system in the bottom layer.
