As previously mentioned, because the circularly polarized high-frequency signal is in case reflected by a barrier, the circularly polarized characteristic of its tool just can thereby change, so after the circularly polarized high-frequency signal is through reflection for the second time, identical Circular Polarisation characteristic (as left-handed Circular Polarisation) when the circularly polarized characteristic of its tool then can change Hui Yuqi and is launched.At this moment, though this one through circularly polarized high-frequency signal of secondary reflection (from the circular polarization aerial unit emission of client device) can be by another embodiment of the present invention the Circular Polarisation filtering portion 3171 that had of first antenna control unit 317 of WiFi radio base station 3 of WiFi network system and the arriving signal processing unit 32.But, because through secondary reflection, this intensity through the high-frequency signal of secondary reflection has decayed to extremely low degree, make this one through the noise that high-frequency signal caused of secondary reflection the transmission between a WiFi radio base station and a client device can't impact for high-frequency signal.
In like manner, though through the circularly polarized high-frequency signal of secondary reflection (from a plurality of first high-frequency signal Transmit-Receive Units 311 that potato masher antenna module 312 is had of exempting from of the WiFi radio base station 3 of the WiFi network system of another embodiment of the present invention, 312,313,314,315,316 emissions) can be by Circular Polarisation filtering portion that client device had and in the arriving signal processing unit, but this intensity through the high-frequency signal of secondary reflection has decayed to extremely low degree, make this one through the noise that high-frequency signal caused of secondary reflection the transmission between a WiFi radio base station and a client device also can't impact for high-frequency signal.Therefore, by the WiFi network system of using another embodiment of the present invention, the transmission efficiency of one high-frequency signal between a WiFi radio base station and a client device just can be raised, and the noise ratio when transmitting high-frequency signal can't therefore aforesaidly be passed through the high-frequency signal of secondary reflection and be dragged down, and make system enlarge the covering scope of WiFi radio base station effectively keeping under the prerequisite of certain excellent service standard.
In sum, because the high-frequency signal that a plurality of high-frequency signal Transmit-Receive Units of exempting from the potato masher antenna module of the present invention are launched has circularly polarized characteristic (as left-handed Circular Polarisation), and after this circularly polarized high-frequency signal is by a barrier (as building or vehicle) reflection, just its circularly polarized characteristic can thereby change (as changing into the dextrorotation Circular Polarisation from left-handed Circular Polarisation).So only one has specific circularly polarized high-frequency signal (as left-handed Circular Polarisation) and just can be passed in the signal processing unit of client device.So, even if aforesaid circularly polarized high-frequency signal through the barrier reflection also together enters the circular polarization aerial unit of client device, the circularly polarized high-frequency signal of these process reflections is owing to have dextrorotation circularly polarized characteristic, and they also can't enter into the signal processing unit of client device.That is to say, those are owing to these just can be suppressed effectively through the noise that the circularly polarized high-frequency signal of reflection is produced, make the noise ratio when transmitting high-frequency signal to be raised, and the transmission efficiency of this high-frequency signal between a WiFi radio base station and a client device also can be raised.
In like manner, because a circularly polarized high-frequency signal can be launched or receive to the high-frequency signal Transmit-Receive Unit of the Anneta module that the WiFi radio base station and the client device of WiFi network system of the present invention institute tool are had respectively all, so when WiFi radio base station (or client device) emission one circularly polarized high-frequency signal, clients corresponding equipment (or WiFi radio base station) just can receive this circularly polarized high-frequency signal easily, and makes noise ratio and transmission efficiency when transmitting high-frequency signal all can be raised.So, WiFi network system of the present invention can enlarge the covering scope of WiFi radio base station, and still keeps certain excellent service standard.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
