One meets to switch over during reservation threshold, and the reservation threshold is configured according to the actual requirements.
Above method flow implementation procedure schematic diagram such as Fig. 4, after flow starts, detected by WIFI terminal removable
WIFI terminal equipment is from the signal intensity with a distance from WIFI terminal and when WIFI is stable；Judge the distance whether less than default
Whether distance or the signal intensity are higher than preset signal strength, when the distance is strong less than pre-determined distance or the signal
When degree is higher than preset signal strength, CPU or MCU make RF switch be connected with first interface by the first control line, lead to simultaneously
Cross the second control line to disconnect external PA power supply, external PA is not worked while control PA work inside WIFI module, output
Low-power level signal is launched by antenna, you can the WIFI patterns of mobile WIFI terminal equipment selection are near work mould
Formula, be advantageous to save power consumption, extend the stand-by time of removable WIFI terminal equipment.
When the distance is less than preset signal strength higher than pre-determined distance or the signal intensity, CPU or MCU lead to
Crossing the first control line makes RF switch be connected with second interface, while external PA power supply is connected by the second control line, makes outer
PA start-up operations are put, while control PA inside WIFI module not work, output low-power level signal is after outside PA amplifications, output
High-power signal is launched by antenna again, you can the WIFI patterns of mobile WIFI terminal equipment selection are remote Working mould
Formula, it is advantageously implemented the long-distance transmissions of WIFI signal.
Due to the difference of space environment, signal intensity and distance are not strict linear inverse relation, and distance is bigger, letter
Number must be weaker, but it is exactly not necessarily that distance is remote that signal is weak, also barrier such as blocks at the factor, as long as therefore signal intensity it is low
It is more than predetermined value in predetermined value or distance to meet first, WIFI terminal is just operated in remote pattern（It is exactly external big work(
Rate PA mode of operations）As long as either signal intensity higher than predetermined value or distance be less than predetermined value meet first, WIFI terminal just
It is operated in closely pattern（It is exactly PA mode of operations inside WIFI module）, this ensures that WIFI communications are normal.

It is distant when, general distance>60m（Pre-determined distance）, or according to signal intensity during the WIFI of detection stabilizations<-80dBm
（Preset signal strength）, CPU/MCU makes RF switch by control line 1（SPDT）With second interface（Port2）Connect, lead to simultaneously
The power supply that control line 2 connects external PA is crossed, makes external PA in running order, now PA does not work inside WIFI module, finally
Antenna end output is high-power, meets remote WIFI signal transmission；When removable WIFI terminal equipment from WIFI terminal away from
From it is more and more nearer when, that is to say, that distance<60m, or according to signal intensity during the WIFI of detection stabilizations>- 40dBm, CPU/MCU
RF switch is made by control line 1（SPDT）With first interface（Port1）Connect, while PA power supply is broken by control line 2
Open, PA is not worked, now PA work inside WIFI module, final antenna end exports small-power.
