Description

Bluetooth radio tracking positioning system and method
Technical field
Patent of the present invention is a kind of radio tracking positioning system, especially bluetooth (Bluetooth) technology has been referred to wherein.
Background technology
Common in the market radio tracking positioning equipment, normally based on technology such as GPS, GSM, WCDMA, it has advantages such as the location is more accurate, and the regional extent of covering is bigger, but shortcomings such as cost height, power consumption height are equally also arranged, and be not suitable for the radio tracking location of zonule.
Bluetooth technology is wireless speech and the data transmission technology of a kind of point to multiple spot, uses the 2.4GHz frequency range.Main advantage is: support a plurality of equipment, have certain penetrability, the omnirange transmission.Use the quick frequency hopping of self adaptation in the Bluetooth technology, thus have that antijamming capability is strong, good confidentiality, the stable advantage of communication quality, also have characteristics such as low-power consumption, low cost, safety and electromagnetic pollution be little flexibly simultaneously.The forward error correction technique that bluetooth adopted and the coded system of optimization can make Bluetooth technology be applied to various abominable wireless environments.Bluetooth protocol is a complete comprehensive agreement, its application model mainly is that agreement is solidificated in the chip, and be built in notebook computer and other need in the intelligent equipment of line, can certainly be directly embedded into wireless module among cellular handset or other equipment, the application controls mode is quite convenient.The characteristics of Bluetooth technology can reduce following some:
● global range is suitable for;
● simultaneously transferring voice and data;
