Step S102: the signal transmission rate to WIFI hot spot transmission data is obtained.
How much signal transmission rate refers to the unit time interior data volume transmitted, and there are two types of the units of transmission rate.
One is chip rate, i.e. the he number of transmitted per unit time, and unit is baud (Baud, abbreviation B), so
Also referred to as baud rate.One digit pulse is a symbol.If the width of symbol is T seconds, B=1/T.
Secondly being message transmission rate, i.e., the information content transmitted in each second, unit is bps (b/s or bps), institute
To be also referred to as bit rate.If the number of the desirable discrete value of symbol is M, T=Ts*log2M, rate of information throughput R=Rs/
log2M, Rs=1/Ts, wherein Ts is the time required for one binary character of hair.And maximum data transfer rate R=Wlog2
(1+S/N).Wherein, W is channel width, and S/N is signal-to-noise ratio.
In the present embodiment, signal transmission rate uses the unit of message transmission rate, can be straight by the APP for the rate of testing the speed

The key technical indexes refers to the ratio of signal and noise in an electronic equipment or system.
Its measurement unit is dB, be can be calculated by formula 10lg (Ps/Pn), wherein Ps and Pn is respectively signal and noise
Effective power.Can be converted into the ratio of voltage magnitude in electronic system: 20lg (Vs/Vn), Vs and Vn respectively believe
Number and noise voltage " virtual value ".By above-mentioned two formula it is found that signal-to-noise ratio the higher the better.
In the present embodiment, pass through signal-to-noise ratio gauge signal quality.Terminal obtains the signal to WIFI hot spot transmission data
Intensity value and detection noise intensity (generally white noise), the ratio of the two be signal-to-noise ratio.
It is optionally, described to detect the step of transmitting the signal quality parameter of data to the WIFI hot spot further include:
Detect the frame losing number of the signal to WIFI hot spot transmission data；
The signal quality parameter to WIFI hot spot transmission data is generated according to the frame losing number.

It is grouped as.Wherein, frame head includes the positioning and other network informations of recipient's host-physical address, and region frame data is then contained
One data volume.For the data volume in read data frame, identical communication protocol must be used between two communication equipments.
For example, the communication protocol that internet uses is Internet protocol (IP agreement).IP data volume includes data volume head
With data field two parts of data volume.Data volume head includes IP source address, IP destination address and other information, and data
The data field of body then includes User Data Protocol (UDP), transmission control protocol (TCP), and contains progress information and reality
The other informations such as the data packet of data.Therefore the equipment in internet can be in communication with each other by IP agreement.
In one embodiment, mobile terminal is using in the frame scan region probe requests thereby (Probe Request)
802.11 networks, the work station for receiving Probe Request frame can first judge that can other side be added network.When mobile terminal is supported
When all data rates required by the network, show to be intended to add with service set (SSID:Service Set Identity)
Enter the network.The work station for receiving Probe Request frame will be with Probe Response frame response, wherein SSID is used to
The MAC Address of belonging network is indicated, i.e. our access point name for seeing before Wi-Fi connection.
In the present embodiment, mobile terminal receives the spy to one Probe Request frame of surrounding broadcast, WIFI hot spot
It surveys after claim frame and returns a Probe Respon frame to mobile terminal, terminal transmission is got by the Probe Respon frame
The frame losing number of Probe Request frame, but due to mobile terminal to WIFI hot spot transmission data signal quality parameter lost with this
The inversely proportional relationship of frame number, therefore, when frame losing number is bigger, signal quality is poorer, and corresponding signal quality parameter is smaller.Work as end
After end detects the signal quality parameter at a certain moment, the optimal of this moment is chosen according to the size relation of the parameter and preset value
WIFI transmission power value.In subsequent time, terminal detects again and obtains new signal quality parameter, further according to the new signal
Mass parameter and the size relation of preset value choose the optimal WIFI transmission power value at current time.That is, terminal to
During WIFI hot spot transmits data, terminal persistently detects signal quality parameter.

The value of parameter can be variant, but may change within the scope of one.In the present embodiment, it is detected under identical transmission rate more
A signal quality parameter calculates average value.
For example, getting 5 letters changed in a certain range by 5 signal quality parameters detected under same rate
Number mass parameter a, b, c, d, e, by average value f=(a+b+c+d+e)/5 as the signal quality parameter under the rate.
Step S108: the smallest WIFI transmitting function for making the signal quality parameter be greater than threshold value is chosen in the set
Rate value transmits data to the WIFI hot spot according to the smallest WIFI transmission power value.Further, described in the collection
The step of minimum WIFI transmission power value for making the signal quality parameter be greater than threshold value is chosen in conjunction further include:
The WIFI transmission power value in the set is traversed according to WIFI transmission power value size order, is traversed described

If so, continue to traverse, if it is not, then using the upper WIFI transmission power value traversed as to described
The performance number of WIFI hot spot transmission data.So-called traversal refers to along certain search pattern, successively does to node each in tree
Once and only do primary access.In the present embodiment, search pattern is the sequence route of WIFI transmission power value from big to small,
In each WIFI transmission power value be node.
If performance number is followed successively by A > B > C > D from big to small in the corresponding power value set of certain rate.Terminal successively traverse A,
B, if C, D judge whether the signal quality parameter is greater than or equal to threshold value according to B, in signal quality parameter traverse B
When greater than threshold value, it is further continued for traversal C；When signal quality parameter is equal to threshold value, using B as the hair to WIFI hot spot transmission rate
Penetrate performance number；When signal quality parameter is less than threshold value, then using A as the transmission power level to WIFI hot spot transmission rate.
For example, the corresponding power of rate 2Mbps is divided into 5 grades, from big to small according to performance number, be followed successively by 17dBm,
16dBm,14dBm,12dBm,10dBm.Judge whether signal quality parameter is greater than preset value according to 17dBm first, if it is not, believing
When number mass parameter is less than preset value, then the corresponding performance number 18dBm of rate is chosen before power classification to WIFI hot spot and emits number
According to, make signal quality parameter be equal to preset value in 17dBm, then data is emitted to WIFI hot spot with 17dBm performance number, if
17dBm makes signal quality parameter be greater than preset value, illustrates that this power is bigger than normal, and performance number 17dBm is cached in memory and selected
It selects and judges whether signal quality parameter is greater than preset value according to 16dBm, if it is not, when signal quality parameter is less than preset value, then
The 17dBm performance number of caching in memory will be called as the transmission power to WIFI hot spot transmitting data, if 16dBm makes letter
Number mass parameter is equal to preset value, then emits data to WIFI hot spot with 16dBm performance number, if 16dBm joins signal quality
Number is greater than preset value, illustrates that this power is bigger than normal, removes the caching in memory at this time, and in memory by performance number 16dBm caching,
Then judge whether signal quality parameter is greater than preset value according to 14dBm performance number, judged with identical step, final choice with
Optimal power emits data.
