  3. 3. What is LTE? 3GPP LTE (Long Term Evolution) is a standard for wireless high-speed data to mobile phones and data terminals. It is based on the GSM / EDGE and UMTS / HSPA, totally over IP, with the increased capacity and throughput using new modulation techniques, smart antenna systems and self-organizing network. IEEE 802.11ac (<6 GHz) IEEE 802.11ad (>60 GHz) ADVANCED ITU-R M.2034 Spectral Efficiency DL 15 bits/Hz UL 6.75 bits/Hz Latency User Plane < 10 ms Control Plane < 100 ms IEEE 802.16m Bandwidth ITU-R M.2034 40 MHz ITU-R M.1645 100 MHz Diretoria de Tecnologia e Plataformas

  20. 20. Final Words The main application (or killer app) is customer experience. And it is improved by using a service with superior quality. Boot-time is one of the most important attribute for Tablets compared to Notebooks. Today, the users are looking for anytime and anywhereservices with readiness and instantaneously. Even in simple web page navigation, quick access is imperative.Wi-Fi popularity pushes a customer expectation for more throughput in macro outdoor coverage. Social networks require greater capacity for data transfer in the uplink in order to post pictures, videos, update contacts etc.According to GSA, there are today over 3,362 HSPA+ devices launchedby 272 suppliers. However, there are only 245 HSPA+ devices that can support 42 Mbps, and a few that can support 84 Mbps. Diretoria de Tecnologia e Plataformas
