Abstract

The invention relates to a multi-channel reverse-to-circle WIFI signal transmitting and receiving device. The device comprises a high-gain antenna device, and more than two equal wireless hotspot devices, band-pass filtering devices, frequency shifting devices and antenna switching devices which are connected in sequence, and the dual-polarization log-periodic antenna adopts a cross structure to realize dual polarization of two single-polarization antenna units, so that the signal polarization loss can be reduced; the antenna is dual-polarized and inverted, so that the radiation direction of the antenna faces the ground, the ground can reflect all radiated energy back, the back radiation of the antenna is reduced, the high-gain antenna device is designed to be of a three-dimensional array structure, a vertical beam can be formed, and the overall gain of the antenna is improved. The WIFI signals are moved to the low frequency band and then transmitted out, the coverage range of the WIFI signals can be increased, and the multi-channel inverse-to-circle WIFI signal receiving and transmitting device comprises a multi-input multi-output signal transmission channel, so that the use reliability is high.

Description

technical field [0001] The present application relates to the field of wireless technology, in particular to a multi-channel inverted WIFI signal transceiver. Background technique [0002] WIFI is a wireless LAN technology based on the IEEE 802.11 standard, which improves the interoperability between wireless network products based on this standard. WIFI is a short-distance wireless technology, which has the advantages of fast transmission speed, low transmission power and no need for wiring. It can meet the needs of personal and social informatization. In the case of weak signals, the bandwidth can be automatically adjusted to effectively ensure the stability of the network. sex and reliability. [0003] The coverage of the WIFI signal transmitted by the traditional WIFI signal transmission device is limited, and the user cannot receive the WIFI signal in an area beyond the coverage of the WIFI, which affects the normal use of the user and has low reliability.
