This leads to the lots of benefits such as to the data center … Sharing happens not only inside the CO, but over the whole access infrastructure. Structure of resource sharing in a centralized RAN.Download figureOpen in new tabDownload powerPoint. Cells from different families coexist and are merged into an optimized continuous coverage distribution when needed. All-band coverage and different service tiers. If people want to cook some special and delicious foods, no matter whether this is their first time to cook them or not, they will check the recipes from some cooking apps to help them cook that. CA among various bands is arbitrary, handover between various cells is smooth, and coordination at cell-edge areas is seamless. 2.4/5 GHz, LTE-U) to provide hot-spot coverage, while the high-frequency small cell (e.g. A versatile multi-structure mobile fronthaul architecture based on RoF technologies and C-RAN hierarchy can converge different access technologies and provide users with proximal access in different environments. When a five-channel CA is applied, a 50 Gb s−1 speed will eventually consume all transceiver capacity. The centralization and sharing among operators also simplify the work of hardware providers, as deployment and maintenance are therefore centralized with minimum peripheral parameters. Mobile fronthaul supports new-style small cells and as well inherits legacy cells, including macrocells from 4G and small cells from wireless local area networks (WLANs). )Download figureOpen in new tabDownload powerPoint, Figure 1. All of the above1. Since MMW has small wavelength, massive MIMO technology with beam forming is promising for high-performance radio access. …, Questions1. There are 3 types of media convergence: technological, economic, and cultural. In comparison with their high-speed counterparts, low-speed DAC/ADCs with high resolution and reliable performance can provide us with an inexpensive option to employ a low-cost intensity modulation/direct detection (IM/DD) scheme for a future digitized optical access network, especially at BSs. Evolution from current RAN to future ubiquitous coverage. 60 GHz) provides very high-throughput coverage for minor-mobility indoor users. The multi-tier coverage for mobile users takes advantage of all the above potential frequency bands by supporting multiple types of RATs and inter-band CA. )Download figureOpen in new tabDownload powerPoint, Figure 5. Two case stud. Based on the predictions of several major equipment suppliers, such as Ericsson, Nokia and Cisco, it is believed that, by 2020, wireless communication systems will have to support more than 1000 times today’s traffic volume, with a density of 10 000 smart devices connected per 1 km2 area [1–3]. A photonic amplitude-changing module or chip is required to change the intensity of the split optical signals. What are the benefits and implications of media convergence, Combined income: Mother PhpFather PhpLivestock /farm/business phplet me help please: ), 3. Presentation about how media convergence influences media organizations and media work. Using IP technology that connects all telecommunication services with a single network, companies can add services to their previous ones, without new investments in infrastructure. With the use of the same media platforms, they now have to work together and are becoming more and more one entity. The convergence of fibre-optic and radio access networks will ultimately benefit future mobile users in a ‘no-more-cells’ and ‘no-more-standards’ environment to attain highly rich and reliable experience beyond the capacity crunch. The multi-tier RAN will improve the cell-edge performance in an integrated heterogeneous environment enabled by fibre–wireless integration and networking for mobile fronthaul/backhaul, resource sharing and all-layer centralization of multiple standards with different frequency bands and modulation formats. Besides cost and management savings, this simplification leads to an important property that the propagation delay is determined only by the fronthaul length. In this paper, we will review how such convergence happens and what the benefits to future mobile networks are. This trend is expected to continue into the 5G era in 2020 in the roadmap of 3GPP (the 3rd Generation Partnership Project) . If the address matches an existing account you will receive an email with instructions to reset your password. A multi-structure mobile fronthaul provides system resilience, flexibility and increased overall bandwidth capacity. Historically, the transition to new mobile technologies has resulted in the need for a fourfold to fivefold increase in backhaul capacity. However, only fundamental centralization is achieved by these techniques and they have been criticized for their implementation complexity and exceedingly low spectrum efficiency. Third, CMW and MMW cells should have the function of providing flexible support for different service coverage areas, including both indoor and outdoor situations . Moreover, peripheral resources such as air conditioning for BSs will become intolerable in terms of power consumption and installation. Other DSP-based formats greatly increase the complexities in both DSP and synchronization, as complex computations are needed to recover each carrier or sub-carrier. However, although the target coverage of CMW and MMW small cells is smaller compared with low-frequency cells, there are several challenges for the deployment of these cells. This is the 21st century, and media convergence … The synchronization between high-speed AD and DA conversion is also a crucial issue that affects signal recovery.
