In fact wireless charging after expansion , LTE, AIE and WiMAX are just a problem of "implementing OFDM and MIMO on the basis of what wireless charging after expansion ". Implementation OF on top of 3GDM and MIMO are LTE, AIE after the expansion of wireless charging , and a new standard is WiMAX. Therefore, the LTE and AIE of WiMAX and 3G are basically the same in technology.
Engineering optimization The purpose of engineering optimization is to expand the network coverage area, reduce the dropped call rate, reduce the call and called failure rate, provide stable switching, reduce noNecessary soft switching, improve the utilization of system resources, expand the system capacity, meet the RF test performance requirements. The main process of engineering optimization is shown in Figure 1: The following is the main method of engineering optimization ① RF data check.
SDH technology is a mature, standard technology that is widely adopted in the backbone network. The application of SDH technology in the access network can bring the huge bandwidth and technical advantages of SDH technology in the core network to the access network field, and make full use of SDH synchronous multiplexing, standardized optical interface, powerful network management ability, flexible network topology ability and high reliabilityAt the same time, it will benefit from the construction and development of the access network in the long term.
The next generation network with softswitch as the core contains several key technologies. Important information systems and basic information networks such as telecommunications networks, radio and television networks, and the Internet in the fields of energy, transportation, and finance that involve the national economy and the people's livelihood should be planned, built, and operated in parallel with security protection facilities, strengthen technical precautions, strictly manage security, and effectively improve their ability to prevent attacks, tampering, viruses, paralysis, and theft. We will strengthen radio safety management and radio frequency support for important information systems.
Wireless charge after expansion, turn off the phone, and then place the phone on the heating table with the phone temperature rises to about 80 degrees, use the disconnecting blade to cut the back cover of the phone. The second step, lay down the motherboard screws and remove the NFC antenna and wireless charging module at the back of the phone after expansion. The third step, disconnect the mobile phone battery after expansion of wireless charging connection line, so that when removing the external configuration does not occur short circuit burning phenomenon.
Manage background applications and self-starting applications: Open the Settings screen of Huawei mobile phone, tap Application options, and select Application startup management. Here, you can see all the installed apps and set the ones that don't need to run in the background to manual management to avoid them starting automatically in the background and taking up running memory.
The instructions for expanding the memory capacity of Huawei mobile phones are as follows: Clearing background and unnecessary data: First, you can swipe up to clear background applications to reduce memory usage. At the same time, use the "cleaning acceleration" function of the "mobile phone manager" app to scan and clean up useless data such as junk files and cache files in the mobile phone and release itMemory space.
Go to the main screen, click the Settings icon, click General in the Settings page, find storage space and iCloud usage in General to enter, enter storage space and iCloud usage, click "Manage storage space" under icloud option, and click "Change storage space plan" in the iCloud interface. In the space program we can see the options from 50G to 2T.
can reliably expand the memory 2 Because the memory of Android phones can be expanded by inserting an SD card, as long as the inserted SD card is compatible and meets the maximum expansion capacity of the phone, thenYou can reliably expand memory.
