Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]
Location is detected based on the nearest public IP address on a device (which can be a computer, the router it is connected to, or the Internet Service Provider (ISP) the router uses). The location depends on the IP information available, but in many cases where the IP is hidden behind an ISP network address translation, the accuracy is only ...
Network routing information collected to the end point of the IP address. Analysis of linguistic data from the device, using pre-trained models that show that some term is frequently mentioned in a certain location (e.g. "the T" vs "the El" vs. "the subway"). Accuracy is improved by: Data scrubbing to filter out or identify anomalies.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [1] It can provide loop detection, authentication , transmission encryption , [ 2 ] and data compression .
From there, your router provides your devices with internet access. At this point, when you visit a website on your phone or laptop, each of those devices has its own internal IP address—also ...
ETR functionality does not have to be limited to a router device; server host can be the endpoint of a LISP tunnel as well. Ingress Tunnel Router (ITR): An ITR is a device that is the tunnel start point; it receives IP packets from site end-systems on one side and sends LISP-encapsulated IP packets, across the Internet to an ETR, on the other side.
WiGLE (Wireless Geographic Logging Engine) is a website for collecting information about the different wireless hotspots around the world. Users can register on the website and upload hotspot data like GPS coordinates, SSID, MAC address and the encryption type used on the hotspots discovered.
"Right now it comes closest to best-of-all-worlds tracking: two-way communication (phone-to-tracker and tracker-to-phone) and a sizable network of Tile users, which can help in locating a lost item."
