Follow-up after a detailed study of our group, indicators of these tests any more deep and familiar, in the supplementary data on this, I hope you understand. In addition to the basic routine before the introduction of several tests, often appear in the RF portion of exceeding certain targets, but there is no good method to solve the case, we added some parts of the test, some here and we share.
If the adjacent cell RX Lev higher than the current RX Lev, indicates the cell phone will handoff to another strong signal of neighboring cells in order to better communication quality. If RXQUAL low, but the RX Lev is not low, then it indicates that there may be an outside interference affect the normal traffic signal at this time to the cell phone base stations need to assign a new frequency or FM mode is enabled. If the cell phone and RXQUAL RXLEV reporting is inaccurate, mobile networks may send some wrong instructions.
In many cases, the factors that influence and restrict the sensitivity of the gain is not the noise figure. Check the matching circuit and SAW Filter SAW’s own performance. Check the transmitter part and receiver part of the shielding effect, whether good isolation; check the transmitter and receiver power supply section is part of a large capacitor filter, stable voltage; EMC is the reception sensitivity of the important factors. The manager and the customer are negotiating the price of cell phone jammer on line.
