WHITE PAPER
LTE OTDOA Reference Guide
With the rollout of LTE comes a new focus on enabling E911 and LBS. Current LTE standards support three independent handset based positioning techniques: Assisted Global Navigation Satellite Systems (A-GNSS), Observed Time Difference of Arrival (OTDO A), and Enhanced Cell ID (ECID). OTDO A is a key technology for positioning when A-GNSS is limited or unavailable, and is extremely important for enabling E911 and other LBS applications indoors.
Because OTDO A technology is so important and testing is so complex, this reference guide provides an overview of the downlink OTDO A technology, important test areas, and Spirent coverage for conformance and R&D performance testing.
