2. Direct-sequence spread spectrum - Wikipedia

   en.wikipedia.org/wiki/Direct-sequence_spread...

   v. t. e. In telecommunications, direct-sequence spread spectrum ( DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation ...

3. Indoor positioning system - Wikipedia

   en.wikipedia.org/wiki/Indoor_positioning_system

   Indoor positioning system. An indoor location tracking map on a mobile phone. An indoor positioning system ( IPS) is a network of devices used to locate people or objects where GPS and other satellite technologies lack precision or fail entirely, such as inside multistory buildings, airports, alleys, parking garages, and underground locations.

4. Global Positioning System - Wikipedia

   en.wikipedia.org/wiki/Global_Positioning_System

   The Global Positioning System ( GPS ), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near ...

5. Modulation - Wikipedia

   en.wikipedia.org/wiki/Modulation

   In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. [1] For example, the modulation signal might be an audio signal representing sound from a ...

6. Wi-Fi positioning system - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_positioning_system

   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.. 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.

7. Gold code - Wikipedia

   en.wikipedia.org/wiki/Gold_code

   Gold code. A Gold code, also known as Gold sequence, is a type of binary sequence, used in telecommunication ( CDMA) [1] and satellite navigation ( GPS ). [2] Gold codes are named after Robert Gold. [3] [4] Gold codes have bounded small cross-correlations within a set, which is useful when multiple devices are broadcasting in the same frequency ...
