. Network Coverage Assessment For GSM network, the index of comprehensive evaluation network includes the absolute receiving level RX, which implies that the coverage level must meet the requirement of load-dry ratio (same frequency c/i≥9db, first neighbour-frequency c/i≥-9db), and for CDMA network, it comes directly from the Shannon formula of information theory, That is, directly measured by the load-dry ratio, including the front/back coverage st

), and sub-blocks, as shown in the following illustration: (x). Tiering is useful for saving code streams, such as sharing information in the next layer, which can be saved on the previous layer, rather than carrying one copy of each underlying structure. However, in the hierarchical structure of H. A, there is no strong dependency between the layers of data organization, which helps to improve the robustness. Because packet switching is prone to errors, if there is a strong dependency, the da

field associated with the foreign key of the master table is updated, a four-level lock (S) must be applied to the sub-table; when the sub-table is indexed, when updating the foreign key association fields of the primary table, two levels of locks (RS) must be added to the sub-table ). When the child table already has RX, the S lock cannot be compatible, resulting in a blocking of updating the master table. If the sub-table does not have a lock, the
received. Why can't the last byte be read during continuous reading? It is tested that this problem does not occur when the log is opened, so it can be confirmed that the delay at a specific location is insufficient. By observing the waveform through the oscilloscope, we can see that the last byte has been read, and the Stop waveform is also displayed, therefore, it is determined that the last byte has not entered the FIFO before the last read of RX-
