Abstract

The teaching apparatus is a wire-less communication network experiment system, which comprises a GSM / CDMA mobile communication terminal experiment box, a GSM / CDMA base-station experiment box, a computer connected with the GSM / CDMA base-station experiment box and fitted with application software, a kernel exchanger star-shape topologically connected with GSM / CDMA base-station experiment box and a computer connected with the kernel exchanger and fitted with management system software. The experiment system adopts software and hardware to cooperate, experiment course is very visual, and operation is flexible and simple, which can be used for experiments relative to courses such as mobile communication, computer network or Ethernet.

Description

technical field [0001] The invention relates to a teaching device, in particular to a wireless communication network experiment system. Background technique [0002] At present, while the mobile communication continues to grow rapidly and the mobile communication network is advancing towards 3G in an all-round way, WLAN (abbreviation for Wireless LAN, that is, wireless local area network), WiMAX (that is, wideband wireless access), UWB (that is, ultra-wideband wireless technology) and New broadband wireless access technologies and short-distance wireless technologies such as Zigbee (that is, wireless communication technology with short-distance and low transmission data rate) have emerged one after another, and the development of the wireless communication industry has presented a new pattern of diversification. [0003] Short-range wireless communication is gradually attracting more and more attention. Low power consumption and miniaturization are urgent requirements and k...
