UE performance evaluation on LTE indoor and outdoor testbeds

Abstract

As the ever increasing demands for higher data rate, lower system latency, and high speed in mobile communications, 4G/LTE systems widely deployed provide better support for these requirements. This increased the complexity of UE (user equipment) and eNBs (evolved Node B) structures, but with simplified core networks. A more flat architecture is achieved to raise data rate and low system latency that are appreciated by users using real-time or high throughput applications such as MAR (mobile augmented reality) or video game applications. The work introduces indoor and outdoor LTE (Long Term Evolution) testbeds for UE performance evaluation via IOT (interoperability) tests and field trials. Throughput for distinct UL-DL (uplink-downlink) configurations were measured to evaluate devices' performance.
