Background

With the development of mobile communication technology, the era of 4G mobile communication has been entered from the 2G and 3G era. The 4G mobile communication adopts OFDM channel coding, uses a multi-antenna technology, has the characteristic of Multiple Input Multiple Output (MIMO), and realizes perfect combination of communication mobility and high-speed internet connectivity; generally, the connection between the mobile communication device and its associated antenna is performed by using a radio frequency cable for external connection, that is, the signal input/power output port of the signal coverage device installed indoors or outdoors is connected to an antenna installed at a higher position through a radio frequency cable with a certain length. The length of the radio frequency connecting cable is from several meters to dozens of meters; in terms of the frequency range used for mobile communication, the general trend is toward the higher frequency band; for example, GSM of 2G mobile communication in China uses 900MHz/1800MHz frequency band, TD-SCDMA of 3G mobile communication uses 1900MHz/2300MHz frequency band, and TD-LTE of 4G mobile communication mainly uses 2600MHz frequency band; the improvement of the use frequency of mobile communication brings the advantages of the reduction of the size and the volume of equipment parts, such as filters and antennas; the adverse condition is that the transmission loss of the radio frequency signal is increased due to the increase of the operating frequency, and the signal coverage distance of the 4G mobile communication is smaller than the signal coverage distances of 2G and 3G under the condition that the signal coverage equipment has the same power and the same antenna gain. Only by increasing the number of signal coverage devices in unit area, gapless signal coverage can be provided, and the use experience of users is ensured; on one hand, signal coverage of 4G mobile communication needs to be set and opened with high density, and on the other hand, the signal coverage equipment is set and opened with high density in reality and has considerable difficulty; at present, common mobile communication equipment is troublesome to install and detach, the equipment is required to be taken out from the inner side, the equipment is easy to damage when the equipment is taken out, and the workload of workers is increased when the equipment is installed and maintained at the later stage;

therefore, when the communication equipment is installed outdoors, the front cover is usually used, the front cover of the existing communication equipment is mostly fixed in structure, and meanwhile, inconvenience is brought to installation work of workers, and besides, the front cover of the existing communication equipment lacks certain convenience;

in summary, the present application now proposes a front cover for a mobile communication device to solve the above-mentioned problems.
