The invention discloses terminal signal detecting equipment and a method thereof based on GSM (global system for mobile communications) software ratio and relates to the field of data measurement of mobile terminals. The terminal signal detecting equipment comprises a software radio peripheral (100), a core controller (200) and an Android interface controller (300), which are sequentially communicated. The core controller (200) comprises a cellphone identification acquiring module (210), a frequency hopping signal measuring module (220) and a data processing module (230), wherein the cellphone identification acquiring module (210) and the frequency hopping signal measuring module (220) are interacted with the data processing module (23). Frequency range covers 900MHz and 1800MHz of GSM, signal strength of various GSM cellphones can be measured at the same time, and measuring accuracy is high. The terminal signal detecting equipment is low in cost, small in size and convenient to carry, can be operated through WI-Fi and is convenient to use.
Description
technical field [0001] The invention relates to the field of mobile terminal data measurement, in particular to a terminal signal detection device and method based on GSM software radio, which has the advantages of small size, convenient portability and low cost. Background technique [0002] With the rapid development of wireless communication, the requirements for terminal signal measurement are getting higher and higher. The GSM terminal signal measurement equipment in the laboratory is bulky, immobile and expensive; and some handheld equipment can only measure the approximate signal strength near the equipment. For those occasions involving confidentiality and life rescue, such as signal monitoring in examination rooms, life rescue in mines and earthquakes, these devices are not enough. Based on the above problems, there is an urgent need for a signal detection device that is accurate in testing, capable of testing multiple mobile phones at the same time, small in size ...
