Uses

• The United States GPS, European Galileo and Russian GLONASS satellite navigation systems
• DS-CDMA (Direct-Sequence Code Division Multiple Access) is a multiple access scheme based on DSSS, by spreading the signals from/to different users with different codes. It is the most widely used type of CDMA.
• Cordless phones operating in the 900 MHz, 2.4 GHz and 5.8 GHz bands
• IEEE 802.11b 2.4 GHz Wi-Fi, and its predecessor 802.11-1999. (Their successor 802.11g uses OFDM instead)
• Automatic meter reading
• IEEE 802.15.4 (used, e.g., as PHY and MAC layer for ZigBee, or, as the physical layer for WirelessHART)
• Radio-controlled model vehicles
