As previously mentioned, because exempting from first high-frequency signal that the first high-frequency signal Transmit-Receive Unit 311 of potato masher antenna module 31 launched by its first base station, a WiFi wireless base station 3 of the WiFi wireless base station mesh network system of another embodiment of the present invention has circularly polarized characteristic (as left-handed Circular Polarisation), so after this first high-frequency signal was by a barrier (as building or vehicle) reflection, its circularly polarized characteristic then can change (as changing into the dextrorotation Circular Polarisation from left-handed Circular Polarisation).At this moment, if second antenna control unit 417 of the 2nd WiFi wireless base station 4 is by Circular Polarisation filtering portion 4171 that it had, restriction only one have specific circularly polarized first high-frequency signal (as left-handed Circular Polarisation) just can by and be passed to its secondary signal processing unit 42, even if then aforesaid first high-frequency signal through the barrier reflection also together enters a plurality of high-frequency signal Transmit-Receive Units 411 of the 2nd WiFi wireless base station 4,412,413,414,415,416, these first high-frequency signals through reflection still can't arrive in the secondary signal processing unit 42 of the 2nd WiFi wireless base station 4.That is to say that those are because these just can be suppressed effectively through the noise that first high-frequency signal of reflection is produced, the signal to noise ratio when making wireless transmission first high-frequency signal can be raised.
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 circularly polarized first 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 first high-frequency signal of secondary reflection can be by the 2nd WiFi wireless base station 4 the Circular Polarisation filtering portion 4171 of antenna control unit 417 of Anneta module 41 arrive in the signal processing unit 42 of the 2nd WiFi wireless base station 4.But, because through secondary reflection, the intensity of first high-frequency signal of this process secondary reflection has decayed to extremely low degree, makes this noise that is caused through first high-frequency signal of secondary reflection can't impact for the wireless transmission of first high-frequency signal between two WiFi wireless base stations (a WiFi wireless base station 3 and the 2nd WiFi wireless base station 4).Therefore that is to say that the signal to noise ratio during wireless transmission first high-frequency signal can't be one be dragged down through the existence of first high-frequency signal of secondary reflection.So in the WiFi wireless base station of another embodiment of the present invention mesh network system, the wireless transmission efficient of aforesaid first high-frequency signal between two WiFi wireless base stations (a WiFi wireless base station 3 and the 2nd WiFi wireless base station 4) just can be raised.
On the other hand, because the wireless transmission efficient of first high-frequency signal between two WiFi wireless base stations (a WiFi wireless base station 3 and the 2nd WiFi wireless base station 4) can be raised, and the signal to noise ratio during wireless transmission first high-frequency signal can be raised, so the WiFi wireless base station mesh network system of another embodiment of the present invention can widen the distance between each WiFi wireless base station that it had (the layout density that promptly reduces its WiFi wireless base station), and still keep certain service level (losing ratio) as signal stabilization degree and signal.
In sum, because exempting from the high-frequency signal that a plurality of high-frequency signal Transmit-Receive Units of potato masher antenna module are launched, base station of the present invention 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, the antenna control unit that the potato masher antenna module is exempted from the base station of another WiFi wireless base station just can be by the Circular Polarisation filtering that it had, and only makes one to have specific circularly polarized high-frequency signal (as left-handed Circular Polarisation) and just can be passed in its signal processing unit.So, even if aforesaid circularly polarized high-frequency signal through the barrier reflection also together enters a plurality of high-frequency signal Transmit-Receive Units of another WiFi wireless base station, 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 another WiFi wireless base station.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, signal to noise ratio when making the wireless transmission high-frequency signal can be raised, and the wireless transmission efficient of this high-frequency signal between two WiFi wireless base stations also can be raised.
In like manner, because exempting from the high-frequency signal Transmit-Receive Unit of potato masher antenna module, the base station of two WiFi wireless base stations of WiFi of the present invention wireless base station mesh network system institute tool all can launch or receive a circularly polarized high-frequency signal, so when a circularly polarized high-frequency signal is launched in one of them WiFi wireless base station, another WiFi wireless base station just can receive this circularly polarized high-frequency signal easily, and signal to noise ratio and wireless transmission efficient when making the wireless transmission high-frequency signal all can be raised.So, WiFi of the present invention wireless base station mesh network system can widen the distance between each WiFi wireless base station that it had (the layout density that promptly reduces its WiFi wireless base station), and still keeps certain service level.
The foregoing description is only given an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that the claim scope is described certainly, but not only limits to the foregoing description.
