1.WIFI positioning is not necessarily the most accurate.
Many people think that the triple positioning and quadruple positioning locators are very powerful, especially the WIFI positioning, which is very high-tech, and can be positioned accurately even indoors. In fact, this is just a gimmick. If you understand the principle of WIFI positioning, you may not have such a high hope for WIFI positioning.
Simply speaking, WIFI positioning only uses the WIFI signal source to determine the IP address of the signal and then resolve it to your location. That is the address you registered with the operator when you pulled the cable. But now almost every family has WIFI, and no one knows which of these signals will be obtained, so the resolution of the location will be accurate to what extent, think about it.
WIFI positioning does have an auxiliary side, but don’t rely too much on it.
2.The smaller the positioner, the higher the technical content, but not as small as possible.
The smaller the volume of the positioner, the higher the technical content without reducing the component configuration. Because for the R&D personnel, it is necessary to lay out so many lines and components in the limited area, and test your comprehensive control ability and overall planning ability. But not as small as possible.
The most important part of the locator is the GPS module and the Cheapest Wrist Watch GPS+LBS+SOS+GSM GPS Tracker For Kid antenna, and the space occupied by the two is relatively large. If the space is neglected, the impact on the signal is quite large. There is no fixed GSM antenna, even a small wire to replace, such a signal is not only poor, but also extremely unstable.
3.Small size wireless locator has difficulty in standby for 5 years.
As we said above, the wireless GPS positioning terminal relies heavily on the battery, especially the battery capacity. If the volume is too small, the battery capacity must not be too large. In the case where the battery capacity is not sufficient, the probability that the positioner can stand by for 5 years is small. To stand for 5 years, the battery capacity must be at least 10,000 mA.
