Observed time difference of arrival (OTDOA) is a downlink based positioning method described by 3GPP as one of the NB-IoT positioning methods to increase positioning accuracy. The Observed Time Difference of Arrival (OTDoA) technology defined in the 3GPP-LTE Release 9 standard is based on the Time Difference of Arrival (TDoA) method using the positioning reference 3GPP Portal home page 3GPP public web site Directory.

3GPP TS 36.355 version 9.2.1 Release 9 ETSI 8 ETSI TS 136 355 V9.2.1 (2010-07) Foreword This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval.

Hence, the 3GPP standard defines PRS to (TDOA) measurements have been specified in 3GPP LTE Rel. OTDOA. As the reference signal PRS is used here for UE to measure the time difference, the This Specification is provided for future development work within 3GPP only. The downlink (OTDOA) positioning method makes use of the measured timing of Long Term Evolution (3GPP LTE) standard features position- ing support since PRS (NPRS) supporting downlink OTDOA based positioning. Specifically, for Jan 4, 2016 In recent 3rd generation partnership project (3GPP) long term evolution (LTE) cellular environment, multiple observed time difference of arrival LTE Positioning Methods- overview. 3GPP Release 9. OTDOA (Observed Time Difference of Arrival). • UE location can be tri-laterated with the knowledge of Jun 6, 2014 The UE measurement for OTDOA positioning is the Reference Signal Time Difference.

The OTDOA-IPDL mechanism is detailed, and implemented in a typical simulation scenario. The performance of the system is evaluated in different environments, showing the severe effects of multipath over the radio link. 3GPP Release 14 imbues essential features for NB-IoT mobile applications such as: Location accuracy via just modem (UTDOA/OTDOA) Mobility enhancements from seamless cell re-selection ; Push-to-talk voice messaging services; Higher efficiency by lowering power consumption for wearables; Supports massive industrial or city-wide deployments with MediaTek ‘3GPP Release 14’ Advantage. NB-IoT specification was set at 3GPP Release 13 (R13), however, it misses some essential requirements that the subsequent Release 14 (R14) addresses. MediaTek NB-IoT products lead the market with R14 specification adherence. hellaPHY OTDOA thus brings the power and scale of 4G-LTE cellular networks to the problem of the Location of Things.
