Broadcast signal coverage drive test system based on SNMP protocol

摘要

With the rapid development of modern information technology and communications industry, traditional broadcasting is experiencing this reform following digitization, networking, and mobile portability. Therefore, ensuring the coverage and stability of wireless broadcast signals is one of the keys to the reform of terrestrial digital broadcasting signals. Therefore, the measured data provided by the coverage test of wireless broadcast signals has important reference value for its coverage planning, implementation and post-maintenance. It plays an important role in the horizontal and vertical development of wireless broadcasting. The drive test is an important way used to test the quality of broadcast signals and plays a very important role in the optimization of wireless networks. This article introduces a transmission test system based on SNMP protocol and programed by Java. It can quickly measure FM signal field strength, multipath and other information, and combine these values with an external GPS to save the values to the local text file. The broadcast signal audio is downloaded and saved to the local disk. The whole DT system operates simply and the power consumption is low. It also has the characteristics that the DT system has small volume, and is very friendly to drive testers.
