These three measurements, of course, require three OTDOA-capable cells, which are measured in pairs, respectively. “Encouraged by the success of the airport experiment two years ago, the project, launched by our company to explore the possibility that public mobile networks, used by the majority of people on a daily basis, may be suitable for a similar drone principle may have entered a

The ESMLC based on these time differences and knowledge of the enodeBs locations calculates the UEs' position. OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs. In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs. Like downlink OTDOA; the method used to determine position of UE using uplink transmissions is known as U-TDOA.

When we connected the phone to the Internet, the mobile revolution was born. Today, as we unlock 5G, we’re applying our mobile expertise to transform industries, create jobs, and enrich lives.

OTDOA for Wideband CDMA (WCDMA) Observed TDOA (OTDOA), as its name indicates, is a TDOA-based approach. It is designed to operate over wideband-code division multiple access (WCDMA) networks. Similar to the E-OTD, OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users.

Following table mentions difference between GPS and OTDOA methods used to determine position of UE. OTDOA for Wideband CDMA (WCDMA) Observed TDOA (OTDOA), as its name indicates, is a TDOA-based approach. It is designed to operate over wideband-code division multiple access (WCDMA) networks. Similar to the E-OTD, OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users. such as OTDOA, can be a better choice for indoor locations and urban canyon environments, while Adaptive Enhanced Cell Identity (AECID) is a good fit in all environments and is especially suitable for terminals that are not equipped with GNSS receivers. SELF-LEARNING AND METHOD SELECTION WPI - with Byron Chen, Lead SE for E911/LBS in LTEi, Alcatel-Lucent LTE Observed Time Difference of Arrival (OTDOA) method in the other hand uses the measured timing of downlink signals received from multiple eNBs to locate the UE according to the neighboring eNBs. OTDOA can be supplement AGPS in dense urban and indoor areas where UE can detect position reference signals (PRS) from three or more eNBs.

OTDOA (Observed Time Difference Of Arrival) is a positioning feature introduced in rel9 E-UTRA (LTE radio). It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC). OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs.

• OTDOA uses hyperbolic multilateral algorithm to determine time of arrival of downlink signals from multiple eNBs (includes 1 serving eNB and 2 or more neighbour eNBs). • TOA from neighbour eNBs are substracted from reference or serving eNB to form OTDOA's. • Each time difference (or range) will determine a hyperbola.
