Description
Technical field
The present invention relates to network communicating system, in particular it relates to WLAN (WLAN, Wireless are divided in a kind of room
Local Area Network) radio switch-in method, Apparatus and system, wireless access point device, antenna.
Background technology
At present, a focus during WLAN becomes radio network technique.WLAN is not by any wire or transmission cable
The LAN connected, and use radio frequency (RF, Radio Frequency) technology to pass through the matchmaker that radio wave transmits as data
It is situated between, transmitting range typically only tens meters.The core network of WLAN generally uses wire cable (Cable), wireless office
Territory network users accesses WLAN by one or more access points (AP, Access Points).
Fig. 1 shows that a kind of room of being applied to divides the intelligence of WLAN to divide wireless access system, including: access point AP11 and
At least one antenna 12, antenna 12 is positioned at different Indoor environments, is connected by feeder line 13 between AP11 and antenna 12；Specifically
Ground, that radiofrequency signal to be sent is assigned as way is identical with the quantity of at least one antenna 12 being connected at least one for AP11
Way radiofrequency signal (2.4GHz operating frequency or 5.8GHz operating frequency)；And respectively by least one way radiofrequency signal one by one
It is sent at least one antenna 12 accordingly；Antenna 12 sends the radiofrequency signal from AP11；Or, to be sent is penetrated by AP11
Frequently signal is assigned as at least one tunnel first sub-radiofrequency signal (the 2.4GHz work that the quantity of at least one antenna 12 that is connected is identical
Working frequency) and at least one sub-radiofrequency signal in tunnel second (5.8GHz operating frequency), and respectively by a sub-radiofrequency signal in road first and
The one sub-radiofrequency signal in tunnel second is sent to an antenna 12 accordingly, antenna 12 send from AP11 the first sub-radiofrequency signal and
Second sub-radiofrequency signal.
The WLAN of administration of room branch as shown in Figure 1, it is possible to realize distributing to sent the power of radiofrequency signal, it is achieved
Multiple Indoor environments provide the signal of radiofrequency signal to cover, and, the signal intensity of radiofrequency signal all will not be by building
The obstruct of body of wall and decay, the signal disturbing between AP is little, little by the interference of other communication system.
But, in system as shown in Figure 1, the intensity of the radiofrequency signal being sent to each antenna 12 from AP11 is equal
Deng, but owing to antenna 12 is positioned at different Indoor environments, the distance between antenna 12 and AP11, radiofrequency signal warp
Signal can be produced decay after crossing feeder line 13 transmission of different distance length, thus the radiofrequency signal that receives of each antenna 12
Also, the intensity of the radiofrequency signal that the antenna 12 that especially distance AP11 is farthest receives is the most weak for intensity, so may result in each
The signal intensity of individual Indoor environment is different, and the connection speed causing each antenna 12 access website STA is different, namely respectively
The access effect of individual Indoor environment is different, affects the access performance of WLAN.
Such as, AP11 sends the transmit power of 5.8GHz radiofrequency signal is the feeder line between 10dBm, AP11 and antenna 12
A length of 15 meters, the decay of radiofrequency signal is calculated by feeder line according to every meter of 1dB, then the radiofrequency signal of 5.8GHz is arrived by feeder line 13
The power reaching antenna 12 is 10dBm-15dB=-5dBm.
The radiofrequency signal of 5.8GHz from antenna 12 eat dishes without rice or wine be radiated 1 meter of spatial dimension big appointment decay 50dB, i.e. distance
The position that antenna is 1 meter, the RF signal strength of 5.8GHz is-55dBm.Further, in the ideal case, distance often doubles,
Signal intensity attenuation 6dB, therefore in distance 2 meters of antenna, 4 meters, the position of 8 meters respectively, the RF signal strength of 5.8GHz is respectively
For-61dBm ,-67dBm ,-73dBm.If if the signal of 5.8GHz is blocked, decay can be more notable, therefore this
In the case of, and signal intensity is the lowest, link speed is the lowest, and substantially STA is on distance 4 meters of remote positions of antenna, and STA links
The speed of AP is the lowest, and the throughput performance that AP is sent to STA downlink data is the most very poor.
On the other hand, to be sent to the radiofrequency signal of AP the most very poor for STA.Because STA is in the maximum transmit power one of 5.8GHz
As below 10dBm.Assume STA distance AP4 rice, arrive the signal intensity=10dBm-12db(4 rice space attenuation of AP)-
50db(air is to the decay of antenna)-15db(feeder attenuation)=-67dBm, i.e. ideal situation be-67dBm.And actually may be used
Can due to the situations such as signal stop make the signal attenuation of the radiofrequency signal of the 5.8GHz that STA sends obtain the most notable the most more
Difference, signal intensity can be at-70dBm, and to be linked to the speed of AP the lowest for STA in this case, and STA issues AP upstream data
Throughput performance the most very poor.
Certainly for the significant situation of downstream attenuation, AP can increase cost transmit power and improve descending performance, but
It is up performance or cannot promote.
If the feeder line using decay the least reduces radiofrequency signal decay in feeder line, but decays the least feedback
The cost of the feeder line of the coaxial cable that the cost of line is relatively common can increase by tens times, and the room of allowing divides WLAN not have the application valency of reality
Value；Further, the general diameter of low feeder line of decaying is big, and feeder line is too hard, and construction is difficult to.
