Method and system for transmission of seismic data
The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path.

Mobile communication system, mobile station, base station, and measurement method
A mobile communication system including a base station which sets a plurality of cells and a mobile station is provided. In the mobile communication system, the base station notifies the mobile station in communication through a first cell among the plurality of cells, of the identification information of at least one cell among the plurality of cells, which can be used for communication with the mobile station and instructs the mobile station to measure a reception state of radio signals.

Mobile communications radio receiver for multiple network operation
A mobile communications radio receiver for multiple radio network operation includes an rf unit for generating a first down-converted signal from a radio signal received from a first radio network and a second down-converted signal from a radio signal received from a second radio network. Further, it includes a first receiver comprising a paging indicator channel demodulator for demodulating a paging indicator channel of the first radio network based on the first down-converted signal, and a second receiver including a pilot channel demodulator for demodulating a pilot channel of the second radio network based on the second down-converted signal.
