Sanjole WaveJudge被Signals Research來評測美國四個營運商LTE網路

Signals Research uses WaveJudge to study four major US mobile operators

 

Sanjole recently collaborated with Signals Research Group (SRG), a US-based research consultancy to monitor and analyze the performance of commercial LTE networks in the United States.  For the study, SRG leveraged the powerful capabilities of the WaveJudge 4900A LTE Analyzer and the IntelliJudge test platform to capture and analyze all protocol exchanges between the eNBs and all mobile devices within the coverage area.   The study included the four largest mobile operators in the United States and all of the major infrastructure suppliers with the testing taking place in San Francisco and Phoenix, Arizona, including the ASU campus in Tempe.

With the information provided by WaveJudge and IntelliJudge, SRG was able to identify measurable differences between networks / vendors, including differences in MIMO utilization, spectral efficiency, eNB scheduler behavior, and network loading.  The results of the study suggest that while LTE can be a highly-efficient air interface its performance can be meaningfully influenced by device and user behavior and an operator’s network strategy.  The 73-page report concluded by noting that operators should focus on in-building solutions, SON and continuous test and monitoring of its networks to maximize performance.
