LTE Application and Congestion Performance

- Today's wireless network complexity and the new applications from smart phones call for an in-depth understanding of the mutual impact of networks and applications. We have created a unique LTE end-to-end network and application performance platform which fulfill several pre-identified needs: (i) model an actual market so that when traffic models change one can quickly assess the overall impact onto a customer, (ii) optimize products to achieve best end user experience, (iii) develop guidelines for network deployments and capacity analysis, and (iv) understand and extend application performance results from the field and lab testing. In this paper we analyze and report the impact of the thin traffic applications on the LTE network. In particular, we analyze the performance of underlying packet transmission protocols and the impact of Machine to Machine telemetry onto the LTE control plane. We further propose a protocol enhancement to reduce the signaling load and packet transmission delays over a LTE network.
