The present invention presents a wireless communication device comprises: a CPU for dealing with the process of the wireless communication device, an RF switch coupled to the CPU for wireless application, at least one wireless transceiver coupled to the RF switch for transmitting and receiving wireless signals, a GPIO (General Purpose Input Output) coupled to the CPU for a variety of connections, and a PCB (printed circuit board) trace connected to the wireless transceiver for providing a function as the 2nd harmonics filter. And the CPU stated above could detect the signal quality of RF signals from the RF transceiver. The indicating element comprises a plurality of LEDs coupled to the GPIO for presenting the signal quality of RF signals detected via CPU. Otherwise, a user interface coupled to the CPU for user control of the wireless communication device. And the device further comprises a housing having the capability of water-proof and wind-resistant. Owing to protect the device from the violent weather, a lightning protection design connected to the wireless transceiver for protection the wireless communication device from lightning.
