A method and a system for indoor positioning within a wireless mesh-type network can be applied where a plurality of access points are located in an indoor space. According to the method, any one access point of the plurality of access points receives a request for indoor positioning transmitted by a portable device, wherein the request comprises received signal strength indications (RSSIs) measured and collected by the portable device. The access point compares the measured and collected RSSIs of the request to RSSIs stored in a fingerprinting database to determine a fingerprinting position using a closest match method and the access point provides, to the portable device, the determined fingerprinting position.
