Welcome to the IT technology community forum, and interact with 2 million technical staff. Table 1 Comparison of WCDMA and GSM signal distribution from the relationship between RSCP and EcIo, when RSCP approaches-100dBm, the corresponding EcIo is-7 ~ -9 dB, and EcIo will reach below-14dB when RSCP is below-110dBm; when the pilot signal is clean, RSCP is-105dB

The concept and use of Java Interface (interface)In an abstract class, you can include one or more abstract methods, but in an interface (interface), all methods must be abstract and cannot have a method body, which is more "abstract" than an abstract class.
Interfaces are declared using the interface keyword, and can be viewed as a special abstract class that specifies what a class must do, rather than how it is made.
There are also many examples of interfaces in reality, such as serial compu
interface technology, is designed for the network system, but with the storage system on the speed of the need to gradually apply to the hard disk system. The Fibre Channel hard disk is developed to improve the speed and flexibility of the multi-disk storage system, and its appearance greatly improves the communication speed of the multi-disk system. The main characteristics of Fibre Channel are: hot-pluggable, high-speed bandwidth, remote connection, large number of connected devices.Fibre Cha
. Global Initialization
When entering a piece of executable code, the JS engine needs to complete the following three initialization tasks:
First, create a Global Object. This Object exists only one copy globally and its attributes can be accessed anywhere. Its existence is accompanied by the entire life cycle of the application. When creating a global object, common JS objects such as Math, String, Date, and document are used as their attributes. Because this global object cannot be directly ac

The execution environment stack is used to ensure that the program can be executed in the correct order. In javascript, each function has its own execution environment. When a function is executed, the execution e

convenience of "Cable select", note that all ide devices must be set to "Cable select". In addition, when the hard disk and the optical drive are mounted on the same data cable, "Cable select" may be invalid-the optical drive does not support "Cable select "! In addition, "Cable select" also requires data line support. If a poor data line is used, errors may also occur. Therefore, for beginners, set the hard disk to "master" or "slave. The "Cable select" setting of the IBM hard disk is very sim
the ATA, such as Ultra Ata, ATA/66, ata/100 and so on.Early IDE interfaces have two transmission modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although the DMA mode system resource consumption is small, but requires additional drivers or settings, so the degree of acceptance is lower. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to support directly, and the manufacturer has introduced the inc
