Abstract
One of the significant challenges mobile telecom operators face is providing a good Quality Of Experience (QoE) to their customers. This QoE in mobile broadband is sometimes measured by throughput and latency that the customers observe when using their APPs or even when intentionally perform speed meter tests using, most of the time, the worldwide well-known APP Speedtest. Since the implementation, the 4G mobile broadband technology has been the network, where customer expectations are high when related to throughput and latency. Although the 4G network, also known as Long Term Evolution (LTE), is the technology, according to frequencies used in Portugal and capable of reaching 391.6 Mbps on the downlink and 75 Mbps the Uplink, on LTE-Advanced with carrier aggregation. Thus, it possible to achieve must higher throughput, and users never observed these throughputs. The throughput obtained depends not only on the network and terminals’ capabilities and configurations but also on the radio conditions measured by signal strength and quality. This paper presents a study of these radio conditions, throughput, and obtained results. Moreover, the results are shown on an analytic and monitoring solution.
