In the corresponding to arrival of Ubiquitous Age, we'd
like to construct the field of education that can train manpower to analyze
mobile communication environment and to construct, operate, and maintain
the system; that can train manpower of practical skill to take charge of
and handle H/W, S/W tasking in mobile communication industry.
Also, this is a practical equipment that can educate those of who are needed
by industry, which can expand employment of science & engineering department
university students systematically |
Features
- Each function composited by Module, using an existed small repeater "Therefore"
as a model.
- Since each Module has Main-path Test-Port, students are able to measure
by themselves during their experiment.
- Direct measurement of terminal basis Parameter is now possible through
CDMA speech quality Test and character communication that use 1 X Data Modem.
- Through experiment, direct measurement for the features of good and badness
is now possible by using On and Off Module
Educational objective
- Understand virtual radio present state of CDMA mobile communication theoretically
and learns systematically through practice.
- By doing wireless measurement system practice, measurement practice of
mobile communication and speech quality. understand the composition and action
principle of products for mobile communication. Through measurement, understand
contents that need in maintenance and manufacture.
- With understanding of all technology of mobile communication with GSM,
CDMA W-CDMA and terminal base radio station, comprehension for wireless communication
network, become a strong foundation for the next generation's a mobile communication
technology.
- Learn basic principles of analog and digital radio communication and does
so that learn connected situation at laboratory through practice.
