\nL1 Band (1575.42 MHz): Mainly used for positioning and navigation.
\nL2 Band (1227.6 MHz): Primarily for higher-precision military and differential GPS applications, though some civilian devices also use it.
\nL5 Band (1176.45 MHz): Offers stronger anti-interference and higher accuracy, mainly used in next-generation GPS devices.<\/p>\n
\n2G (GSM\/GPRS): 850\/900\/1800\/1900 MHz
\n3G (UMTS\/HSPA): 850\/900\/1700\/1900\/2100 MHz
\n4G (LTE): Wide range of frequencies depending on the country and carrier, typically 700-2600 MHz.
\n5G (NR): Generally in the 600-3800 MHz range, with even higher millimeter-wave bands (24-100 GHz), though less common in regular GPS ankle trackers for now.<\/p>\n
\nBluetooth: 2.4 GHz
\nWi-Fi: 2.4 GHz and 5 GHz<\/p>\n
\nSome ankle trackers may use low-frequency RF signals for more precise short-range tracking, such as 433 MHz or 915 MHz.<\/p>\n![\"Ankle](\"https:\/\/www.gpsjammers.net\/wp-content\/uploads\/2025\/05\/Gosafe-G737-Ankle-Bracelets-Tracker.jpg\"){kind=tracking}
