Product Description
Open Mobile Communication Innovative Experiment System closely follow the courses of "Mobile Communication" and "Spread Spectrum" etc, and integrates three types of multiple access communication methods: CDMA, TDMA and FDMA. By using open and transparent design, it demonstrates the principle and the composition of mobile communication system, and also its business process that can fully meet the needs of teaching and curriculum design and development of Experiment needs colleges and universities, vocational colleges communication related major mobile communication.
Product Feature
(1)It uses the design of mainboard together with modules, and experiments are close to the mobile communication theory course content, which covers the main knowledge points of mobile communication system principle. There are total 45 experiments including unit experiment, system experiment and development experiment to ensure adequate distribution of Experiment hours.(2) Functional circuit is divided into pieces according to the circuit flow, accompanied by explanatory text, block diagram to help the experimenter to grasp the design and implementation process. The shipping CD provides the necessary circuit design schematic and reference material. (3) All open design, programming download interface, free pin interface, as well as related software to facilitate the secondary development. Platform can be used for large-scale design project, it's aimed at full exercise of student's self-development and practical ability start from simple function to develop large-scale design project step by step according to the easy-to-difficult teaching pattern. And it also recommends additional topics to stimulate student interests. (4) The system covers 2G, 2.5G and 3G mobile communication knowledge points, closely reflect the direction of mobile communication development, to guide the more in-depth study for the experimenter. (5) It provides the software, test routines, courseware, reference manuals and other means to assist the Experiment teaching.
