Value.Corresponding History Performance Data can be determined by the Frequency Band Selection result in step S107.
Optionally, on the basis of first embodiment, in fourth embodiment of the invention, as shown in Fig. 2 the step S107 it
Also include afterwards：
S1071, terminal type is determined according to the first quantity of the STA,
S1073, determines that the STA that first network interface card and second network interface card are each distributed is accessed according to the terminal type
The maximum of quantity.
Optionally, on the basis of first embodiment, in fifth embodiment of the invention, the step S1073 is specifically included：
Corresponding interference environment is distinguished according to the terminal type and first network interface card and second network interface card corresponding
Allocation strategy determines that the STA that first network interface card and second network interface card are each distributed accesses the maximum of quantity.
Optionally, in step s 107, according to the sum of STA in the first quantity and the WLAN of the STA
Determining the result of first network interface card and second network interface card corresponding working frequency range respectively can have following several：
First, if determining access terminal according to the sum of STA in the first quantity and the WLAN of the STA
STA is the terminal for only supporting 2.4G, then,
Determine that first network interface card and second network interface card distinguish corresponding working frequency range, radio frequency that will be on two network interface cards
Mouth all switches to 802.11b patterns, all releases 2.4G signals；And the power of the radio frequency mouthful on two network interface cards is reduced to 20%；
Wherein, in step S1071, if the first quantity is 0, it is determined that the terminal type of the STA is pure 2.4G classes
The terminal of type.
In step S1073, when terminal type is pure 2.4G types, the first network interface card and second network interface card are corresponded to respectively
The corresponding allocation strategy of interference environment be：
If network interface card is in noiseless or same interference environment, the accessible terminal quantity on each network interface card is defined as
The average of all terminal STA sums；Otherwise, if network interface card is in noisy environment, the corresponding letter of few network interface card is disturbed
Road can be according to interference strength pro rate terminal, it is ensured that the few network interface card multi-access terminal of interference.
After allocation strategy is determined, according to the terminal type and first network interface card (network interface card 1) and the second network interface card (net
2) the corresponding allocation strategy of corresponding interference environment determines what first network interface card and second network interface card were each distributed to card respectively
The maximum of STA access quantity, general, can be with eventually after the quantity maximum for the STA for confirming to can access on the first network interface card
End sum subtracts the quantity maximum that the maximum is the STA that can access on the second network interface card.
In addition, in one embodiment of the present of invention A, if network interface card be on noiseless environment, each network interface card can
Number of access terminals can also be calculated as follows：
Step 1: noiseless environment, it is U to determine channel utilization；
Step 2: determining that total number of terminals is C；
Channel utilization is higher to show that interference is more serious, and the number of users of association should be fewer, to ensure the business body of user
Test
Step 3: the channel utilization for determining wireless access point AP card of surfing Internet 1 is u1, the channel utilization of network interface card 2 is u2；
Step 4: the accessible terminal quantity of network interface card 1 can be：[1- ((u1-U)/((u1-U)+(u2-U)))] * C, button
Remaining quantity is the accessible terminal quantity of network interface card 2 in the accessible terminal quantity of inter nic 1, total number of terminals C.
Wherein, it is determined that network interface card is in noiseless or during with interference environment, interference value can be according to above-mentioned Channel assignment
During the obtained value of scan channel judged, such as channel profit of the upper 2 2.4G network interface cards of AP on its current operating channel
All it is that 20%, channel bottom is made an uproar all as -85db with rate, then it is assumed that interference is identical, i.e., with interference.If channel utilization is 10%,
Make an uproar as -90db at channel bottom, then it is assumed that be noiseless.
Second, if determining access terminal according to the sum of STA in the first quantity and the WLAN of the STA
