Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.Need what is illustrated
It is that, in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
It should be noted that the art in description and claims of this specification and above-mentioned accompanying drawing
Language " first ", " second " etc. are for distinguishing similar object, without specific for describing
Order or precedence.
Endurance is to weigh an importance of product at present, as a high performance
Ufi, will if its power consumption can be reduced to greatest extent while its work is effectively supported
Its endurance can largely be improved.Ufi (is said by taking AP as an example below at present
It is bright) coverage be a definite value, for example be 10 meters, so if AP to be accessed
Terminal (that is, site STA) is located in 5 meters of distance AP region, so distance AP 5
Rice to the Power coverage in 10 meters of region be actually unnecessary, if can suitably adjust
Whole AP coverage, such as the Power coverage for adjusting AP can then ensure to 6 meters
While terminal normally accesses, the electromagnetic radiation outside 6 meters is reduced, reduces the expense of system broadcasts,
So as to reach the purpose of economize on electricity green.
For such scheme, a kind of method of adjustment of power is proposed in embodiments of the present invention,
Fig. 1 is the flow chart of the method for adjustment of power according to embodiments of the present invention, as shown in figure 1,

And reduce the unnecessary waste of power, so as to reach the purpose of economize on electricity.(S4 to S6 is corresponding
S906-S918 in Fig. 9)
Aforesaid operations flow is specifically described below：
In the present embodiment, it is possible to make full use of AP power, reduce unnecessary power and cover
Lid, so as to reach the purpose of system saving electricity.Accessed based on terminal (corresponding to above-mentioned STA)
During AP, AP can be detected and effectively be assessed the location parameter of terminal；The coverage of AP sides
Quantified with distance, the positional information for comparing accessed terminal is gathered in the same time；Notice
Coverage setup module 86 sets AP coverage；There is specific application module on AP
Come the wireless signal acquisition module of the existing terminal access of collection communication, the covering to having set
The effect of scope is fed back, the foundation as power conditioning module.
Wherein, the location parameter for assessing terminal assumes that when terminal sends access information data can be carried
The initial power of transmission, so come out in AP lateral roots according to the decay calculation of the signal power received
STA to AP wireless distances.
STA to AP distance can according to radio magnetic wave free-space propagation channel radio
Communication distance substantially draws, radio wave propagation loss (also known as decaying) is only and work in free space
Frequency f is relevant with propagation distance d, in free space spatial it is assumed that a kind of ideal
Transmission conditions, but the calculating error for closely propagating is not too large, mainly passes through
Below equation is drawn：
Los=32.44+20lgd (Km)+20lgf (MHz), wherein, Los is transmission loss,
The ratio of receiving power and transmission power can be defined as, d is transmission range, and f is transmitting work(
Rate.
AP receives STA access request, gets the location parameter of terminal therefrom, it
Notify coverage setup module 86 that AP coverage is set afterwards；It is assumed that the covering of terminal
Scope can be provided from 2 meters 10 meters, with 2 meters of Power coverage distances for interval, set
The reasonability and validity of AP coverage need to access signal feedback by terminal to judge,
The signal intensity of statistics access signal at AP, and maintenance is strong for each STA signal
Information is spent, the signal strength information provides voucher to power conditioning module, until power is to one
Stationary value, can be to the coverage distance at least one that estimates in order to reduce power consumption as far as possible
Secondary recurrence, coverage is reduced into by an interval, if the distance estimated is 5 meters, according to
According to the settable value of existing coverage, coverage can be arranged to 6 meters, and remember
Access signal intensity corresponding to the STA is recorded, next by 4 meters of the coverage modulation, and is recorded
The access signal intensity of the STA, if signal intensity can continue without significant change twice
The coverage is reduced, if signal intensity attenuation is more obvious, adjustment coverage is increasing
Add, the coverage before returning to, illustrate, except statistical signal during the closed loop feedback
It is dominant to need to be concerned with the STA normally to access outside intensity, and carried out by the AP
Data communicate, so far the power adjusting circuit closed.
The method point of penetration for being automatically adjusted coverage based on distance and being reached economize on electricity purpose is work(
Rate makes full use of, and in order to preferably utilize wireless power, (can correspond to above-mentioned in equipment
AP) on increase hardware antenna, improve antenna transmitting-receiving efficiency, equipment open when can orient
The signal of existing access channel is scanned, so as to substantially position STA, can be obtained in access area
One sector and dimension distribution, most the wave beam of each antenna is all focused on where STA at last
Sector, power is set to obtain most sufficiently utilizing.
By the scheme proposed in the embodiment of the present invention can complementary sleep mode to economize on electricity
Contribute, the sleep mode in correlation technique is to be directed to scene when being accessed without STA, and this hair
Bright embodiment is from when having STA accesses, and coverage is set with reference to the position of service goal
One more reasonably value is (because AP coverage and AP power are positively related, institutes
So that a rational performance number can be set), so as to reach the purpose of economize on electricity.
