Problems solved by technology
[0005] The technical problem to be solved by the present invention is to provide a WiMAX CPE equipment antenna remote method and CPE equipment to solve the problem of using a radio frequency power amplifier with a large power capacity to compensate the radio frequency coaxial cable when the WiMAX user terminal product uses the outdoor antenna remote function. The cost of insertion loss is high, and the heat is large, the design is difficult, and due to the increase of the insertion loss of the RF coaxial cable, the length of the RF coaxial cable is greatly limited.

Embodiment Construction
[0038] The CPE equipment of the present invention will be described with reference to the accompanying drawings.
[0039] The core idea of the present invention is to modularize devices such as low noise amplifiers and final power amplifiers into outdoor communication modules; at the same time, during the structural design process of CPE equipment, the structure of the indoor communication module can be reserved for the expansion connection of the outdoor communication module slot. When using the remote function, take out the outdoor unit module and install it outdoors to connect with the outdoor antenna, and connect it to the indoor communication module through a radio frequency coaxial cable to form a remote system. When the remote function is not used, the outdoor communication module can be inserted into the expansion connection slot of the outdoor communication module, and connected with the outdoor communication module and the built-in antenna to form a complete CPE de...

The invention discloses a worldwide interoperability microwave access user terminal equipment, comprising an Ethernet processing module, an indoor communication module, an outdoor communication moduleand an antenna, wherein the outdoor communication module is connected with the antenna and used for completing the emitting and receiving of the radiofrequency signal; and the indoor communication module is connected with the outdoor communication module and used for converting the user data into the radiofrequency signal, providing the radiofrequency signal to the outdoor communication module, receiving the radiofrequency signal from the outdoor communication module and converting the radiofrequency signal into the user data. The equipment has high receiving sensitiveness, and the remote antenna radiofrequency coaxial cable has long distance, thus meeting the requirement of the user and improving the user experience.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a global interoperability microwave access user terminal equipment. Background technique [0002] With the rapid development of Worldwide Interoperability for Microwave Access (WiMAX) technology, IP networks have gradually become an indispensable tool in people's daily work and life. In the current WiMAX CPE (Customer-Provisioned Equipment, hereinafter referred to as CPE) product design, in order to meet the flexibility of users, operators generally put forward the product design requirements of CPE equipment with outdoor remote antennas. The usual design solution is to use the outdoor antenna of the CPE equipment plus a remote 50-ohm RF coaxial cable. This method has the following disadvantages: [0003] First of all, due to the large insertion loss of the 50-ohm RF ohm coaxial cable used for the remote antenna in this design, the power loss of the RF signal will be large. T...
