Because of technological advancements, location-based services are always evolving with the passage of time. The current study discussed significant developments in the field of locationbased services technology. LBS Indoor Systems, LBS Satellite Systems, LBS GPS System, and Outdoor Systems employing Terrestrial BSs are all part of the localization infrastructure. The report also discusses the benefits and drawbacks of various outdoor systems that employ Terrestrial Base Stations, such as the Global System for Mobile Communications. WCDMA (with IPDL, TA-IPDL, and OTDOA-PE), Smart Antenna Systems, and Distributed Antenna Systems, GSM (with E-OTD), GSM (with CELL-ID), CDMA/GPRS (with A-GPS), CDMA/GPRS (with A-GPS), CDMA/GPRS (with A-GPS), CDMA/GPRS (with A-GPS), CDMA/GPRS (with A-GP (with A-GPS) -AFLT+AGPS, Wireless Assisted GPS and AFLT: GPS One A Hybrid Solution, WCDMA (with IP), WCDMA (with IP), WCDMA (with IP), WCDMA (with IP), WCDMA (with IP), WCDMA (with IP), WCDMA (DAS). Some of the techniques discussed in this paper are localization by Cell-ID, localization by Prediction, localization by Angle of Arrival (AOA), localization by Time of Arrival (TOA) and Observed Time Difference of Arrival (TDOA), localization by Finger Printing, and Hybrid Localization AOA-TOA Based. Low-power wide-area networks (LPWANs), cellular 5Gbased positioning technologies, ZigBee (Mesh Protocols), and WiFi6 have all been studied in relation to the Internet of Things (IOT). This document also covers NLBS (which includes Bluetooth Low Energy technology, WLAN, and Infrared), UWB, and Vehicle to Vehicle Communications.
