This paper offers an introduction to the mobile communication standard known as LTE Advanced, depicting the evolution of the standard from its roots and discussing several important technologies that help it evolve to accomplishing the IMT-Advanced requirements. A short history of the LTE standard is offered, along with a discussion of its standards and performance.
It increases the capacity and speed using a different radio interface together with core network improvements. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported. The standard is developed by the 3GPP 3rd Generation Partnership Project and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is sometimes known as 3. However, other nations and companies do play an active role in the LTE project. The goal of LTE was to increase the capacity and speed of wireless data networks using new DSP digital signal processing techniques and modulations that were developed around the turn of the millennium. A further goal was the redesign and simplification of the network architecture to an IP -based system with significantly reduced transfer latency compared with the 3G architecture.
To move to higher-speed networks that can cater to customer demand for mobile broadband multimedia applications, the 3GPP has developed the latest LTE-Advanced LTE Release 10 standard, which will be fixed in December This book focuses on LTE and LTE-Advanced, and provides engineers with real insight and understanding into the why and how of the standard and its related technologies. This book is written by engineers from Ericsson--the world's leading telecommunications supplier--who was heavily involved in the development of the standard. Erik Dahlman works at Ericsson Research and are deeply involved in 4G and 5G development and standardization since the early days of 3G research. Stefan Parkvall works at Ericsson Research and are deeply involved in 4G and 5G development and standardization since the early days of 3G research.
One of the key factors for the successful deployment of mobile satellite systems in 4G networks is the maximization of the technology commonalities with the terrestrial systems. An effective way of achieving t Content type: Research Article. Published on: 5 November We present a design of a complete and practical scheduler for the 3GPP Long Term Evolution LTE downlink by integrating recent results on resource allocation, fast computational algorithms, and scheduling. In data packet communication systems over multipath frequency-selective channels, hybrid automatic repeat request HARQ protocols are usually used in order to ensure data reliability.
The architecture used in LTE was designed to surpass the mobile data rates that were available using 3G technologies. This simplified, flatter version of the network architecture mean response times are much quicker and therefore users of the network would realise much better data rates. The main aim for LTE-A Pro is to increase the data speeds and bandwidth that are currently available for mobile communications. User experience will be significantly improved as a result optimising the capacity, performance and functionality of existing LTE-A networks. Latency will also decrease, allowing for much quicker response times; vital for the development of IoT internet of things technology.
Long-Term Evolution (LTE) is a standard for wireless broadband Note: In an LTE or LTE-A network, 10% of total bandwidth is used for the guard band. For example for the different values of Transmission_Mode Index, Transmission_Mode.
LTE represents a radical new step forward for the wireless industry, targeting order-of-magnitude increases in bit rates with respect to its predecessors by means of wider bandwidths and improved spectral efficiency. Beyond the improvement in bit rates, LTE aims to provide a highly efficient, low-latency, packet-optimized radio access technology offering enhanced spectrum flexibility. The LTE design presents radical differences at every layer. Like many other communication technologies e.
This ongoing race of increasing sequence numbers of mobile system generations is in fact just a matter of labels. What is essential is the actual system capabilities and how they have advanced. The evolution of 3G systems into 4G is powered by the creation and growth of new services for mobile devices, and is enabled by advancement of the technology available for mobile systems. There has also been an evolution of the environment in which mobile systems are deployed and operated, in terms of levels of competition between mobile operators, challenges from other mobile technologies, and new regulation of spectrum use and market aspects of mobile systems.
Поднял посверкивающую полуавтоматическую беретту и нацелил ее на дверь, а потом опустил себе на колени. - Сьюзан, - сказал он торжественно. - Здесь мы в безопасности. Нам нужно поговорить. Если Грег Хейл ворвется… - Он не закончил фразу.
На экране агент с короткой стрижкой безнадежно развел руками. - Сэр, ключа здесь. Мы обыскали обоих.
