Joint processing JP in CoMP technology provides multiple data transmission points for each user among multiple cooperated radio base stations. Hard handover mechanism is adopted to be used in LTE-Advanced. While the radio resources in the system are fixed, the more multiple data connections a user has, the more radio resources are used for the extra data connections, thus the lower capacity a system becomes. System performance of Limited CoMP Handover Algorithm is evaluated and compared with open literature handover algorithm via simulation in this paper. The simulation results show that Limited CoMP Handover Algorithm outperforms open literature handover algorithm by having shorter system delay and less system load whilst maintaining a higher system throughput in a high congested network.
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. Fixed telephony POTS and earlier generations of mobile technology were developed for circuit switched services, primarily voice. This also affected the first development of 3G,which was primarily based on circuit switched data, with packet-switched services as an add-on. IP is in itself service agnostic and thereby enables a range of services with different requirements.
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.
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. In terms of radio access, CDMA has given away to time and frequency multiple access. At the network layer, a flatter architecture is being defined that represents the transition from the existing UTRA network, which combines circuit- and packet-switching, to an all-IP system.
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.
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.
Машина была оплачена человеком в очках в тонкой металлической оправе, и он должен был его дождаться.
Тут что-то не так, - наконец сказала. - Не думаю, что это ключ. Фонтейн глубоко вздохнул. Его темные глаза выжидающе смотрели на Сьюзан. - Мисс Флетчер, как вы полагаете, если это не ключ, то почему Танкадо обязательно хотел его отдать.
