Applied to plurality of application scenes, such as remote meter reading, shared bicycle, intelligent parking, asset tracking, wisdom agricultural.But at present
The intelligent tester of NB-IoT network quality, signal coverage condition etc. is need to be mentioned in terms of efficiency on domestic market
Height, function also need further perfect, and can not realize and test the NB-IoT network quality of global different frequency range.
Meanwhile country's eMTC network test is in the blank phase at present, lacks manufacturer and produces corresponding test equipment.
Currently, being directed to global system for mobile communications (GSM, Global System For Mobile
Communications)/TD SDMA (TD-SCDMA, Time Division-Synchronous Code
Division Multiple Access)/time-division long term evolution (TD-LTE, Time Division Long Term) integral type
Tester and test method are to pass through global positioning system (GPS, Global by external power supply continued power
Positioning System) module is responsible for completing the acquisition of longitude and latitude, the location informations such as height above sea level, and wireless communication module is negative
Duty completes the operational trialss such as circuit domain/packet domain, data under GSM/TD-SCDMA/TD-LTE network, and data acquisition module is negative
The information such as signaling, the data that duty acquisition wireless communication module and GPS module report, remaining module cooperative are completed data statistics, are deposited
The functions such as storage.
