Product Features


GSM mobile communication system experiment kit is tightly close to such teaching syllabus as Mobile Communication and etc, experiment contents are abundant, which could fully meet the teaching requirements of such course as mobile communication on communication’s major among colleges and universities.

  1. The experiment kit combines with theoretical teaching of Mobile Communication course, reference GSM standard, according to the protocol, it vividly reappears the basic process of mobile station and base station interaction through simulating a base station, among which it has three-layer protocol of GSM communication, and it is probably to analyze such processes as mobile phone network access, pick up, dial, ringing, hang up through logic analyzer during the interaction process of experiment kit (base station) and mobile phone in experiment kit.
  2. The experiment kit has key technology demonstration and experiment of mobile communication, as well as mobile station access, mobile station call, base station call, power control, double computer network full duplex speech communication system experiment, and etc, in addition, it could observe other working state on access computer interface screen of experiment kit.
  3. The experiment kit could realize three kinds of wireless standards, such as GSM900, E-GSM and DCS1800. The three wireless standards could automatically switch and network switch. The experiment kit has its own operation number, therefore it will not exist the problem of charging after mobile phone network access, in addition, users would not be restricted by time and expenses in processing experiments and scientific research.
  4. It adopts eight-channel time division multiple access (TDMA) communication technology of frequency division duplex (FDD), 270.833Kbit/s Gaussian minimum shift keying (GMSK) modulation mode and balanced demodulation technology. It could observe experiment waveform and communication data with oscilloscope and logic analyzer.
  5. It adopts DSP, FPGA and many kinds of advanced information treatment method to design and realize GSM air interface three-layer protocol, which we process independent intellectual property rights. The product filled the blank of GSM testing aspects for the domestic in 2002, and State Information Department has given operational number of the system: 00101(00101 has the same meaning with China Mobile and China Unicom)
  6. It realizes the control of emission power that could reach better transmission quality under the condition of unnecessary for the maximum emission power, which can reduce emission power and thus reduce interference to other communications and harm to people from radio frequency to the minimum, therefore it is suitable for users to make experiments and study on the structure of GSM communication system for a long time.
  7. It adopts plexiglass buffle for protection
