Media convergence 1. Still, media convergence may stifle the quality of the content and allow for a possible media monopoly when a select few media companies control most of the media. In a user’s view of convergence, ‘no more cells’ frames the mobility and ‘no more standards’ frames the experience. Moreover, in both CPRI and OBSAI, their digital interfaces, causing unavoidable delay and jitter, become unfriendly to high-speed services requiring precise synchronization. Media convergence is important because in today’s technologically advanced world, different forms of technology continue to be released and are better than their former models because they can simply do more.

Assisted by MWP technologies, the converged design enables more efficient management for all the light sources, e.g. Therefore, it is necessary to centralize and thus eliminate the BS cost, and consequently allow multiple heterogeneous services to share them [5]. Future 5G RANs will increase the requirement for backhaul capacity by at least 10 times considering the effective throughput for each user and multi-antenna technologies. In this case, the virtual BS from each RAU’s viewpoint is identical. Currently, orthogonal frequency division multiplexing (OFDM) [16], carrier-less amplitude and phase (CAP) modulation [17] and sub-carrier multiplexing (SCM) [18] have been deeply investigated. )Download figureOpen in new tabDownload powerPoint, Figure 4. The convergence of fibre-optic and wireless communications enables radio-over-fibre (RoF) fronthaul as a new form of RAT and hence fully centralized RANs. Bit rates above 100 Gb s−1 have been attained by adopting spectrum-efficient modulation formats and digital coherent detection enabled by fibre–wireless convergence [28–30]. Different from RRHs, only O/E (optical-to-electrical), E/O (electrical-to-optical) and a few RF components are needed at the end of the fibre fronthaul as the radio access units (RAUs). Evolution from current RAN to future ubiquitous coverage. Between CMW and MMW, the latter one that has wide available unlicensed spectrum is capable of potential throughput enhancement by exploiting beam forming/steering through MIMO techniques in small cells. Data allows us to make better predictions and creates new models of customer behavior f… First, they have to cope with unfriendly high-frequency propagation conditions, such as large path loss, blocking object attenuation in real environments and signal blockage loss due to atmospheric absorption [23]. Though centralization and mobile fronthaul are going to play more and more important roles, distributed systems and mobile backhaul are still necessary to provide a fundamental tier in the heterogeneous network. Distance is not a barrier. jointly proposed the concepts and jointly prepared the text for this article. It educates people. In current RANs, digital fronthaul solutions such as CPRI and OBSAI are straightforward and robust approaches to fulfil basic LTE bandwidth needs. Two case stud. Two case stud .

Structure of resource sharing in a centralized RAN. All of the above1. The convergent networks will generate profound changes in RAN architecture, backhaul and fronthaul links, and the way we use frequency bands for future wireless communications. Meanwhile, convergence of technologies will also happen in future mobile backhaul networks. Convergence is the process where several media channels come together to exist and operate in synergy. By converging traditional low-frequency radio and newly deployed high-frequency radio, RANs can provide an all-band access pipe for the highest channel capacity. The centralized radio access network (C-RAN) architecture has been proposed to extract the baseband signal processing functions from distributed BSs and collocate the baseband units (BBUs) into a pool for centralized signal processing and management, as shown in figure 2b [7]. 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. Operators can effectively manage the communications between services from the upper layers inside the CO so that the traffic through the SGWs can be eliminated. Once a country which had fifty major media companies in 1983, America now, has only nine important multinational media conglomerates, some of which include Walt Disney, Time Warner, Comcast, News Corp., CBS and Viacom. To reach high spectral efficiency, advanced MMW technologies are desired for signalling, and this is realized by the supporting fibre–wireless convergence. This trend is expected to continue into the 5G era in 2020 in the roadmap of 3GPP (the 3rd Generation Partnership Project) [4]. A multi-tier radio access network (RAN) combining the strength of fibre-optic and radio access technologies employing adaptive microwave photonics interfaces and radio-over-fibre (RoF) techniques is envisioned for future heterogeneous wireless communications. This heterogeneous sharing is especially efficient if the number of cells is high or the services share similar DBA schemes. Mobile PhonesPrintersd. Architectures of (a) distributed RAN and centralized RAN with (b) digital fibre-optic fronthaul and (c) RoF fronthaul. This fully centralized RAN architecture based on fibre–wireless convergence provides a solid solution for high-throughput access systems with superior features [10]: — RAUs are highly simplified, which reduces the room needed for cell sites, power consumption and demands for peripheral and technical support; — the cloud BBU pool reduces the number of BSs by several-fold; each BBU can serve multiple RAUs to increase the infrastructure utilization rate; — CO enables centralized processing and more flexible and efficient dynamic bandwidth allocation (DBA) and radio resource management (RRM); as BBUs work together, joint processing and cooperative radio to mitigate inter-cell interference (ICI) provide a higher spectral efficiency; — centralization and DBA make the network more adaptive to non-uniform distributed traffic caused by the inter-cell movement of UE; — RoF fronthaul simplifies the generation and distribution of all frequency signals in a cost-effective way by microwave photonics (MWP) techniques and provides a seamless integration with centralized RANs; — the flexibility of centralization supports heterogeneous services and supplies an open platform for operations and maintenance (O&M), upgrade and service expansion for smooth evolution; and. On top of a centralized RAN, RoF provides high-level centralization and minimizes complexity distribution. The low-frequency small cells are normally in unlicensed bands (e.g. (Online version in colour. In current 4G networks, eNodeB, orthogonal frequency-division multiple access (OFDMA) and IP core are the major technologies that define the advancement of LTE from previous generations. Media convergence in the digital era means the changes that are taking place with older forms of media and media companies. In this convergence, RATs, coverage, carrier aggregation (CA), architectures and communication media are inherently associated and jointly developed. Figure 1. )Download figureOpen in new tabDownload powerPoint, Figure 5. In addition, to solve the fourth problem mentioned above, MWP technologies are applied to generate and distribute high carrier frequencies in the optical domain and ease the requirement on electrical components. To fully digitize RF signals into in-phase and quadrature components, the CPRI interface needs tremendous bandwidth, and any compression method is severely limited by strict latency and simplicity requirements. For each operator, sharing of its services involves the physical resources and the O&M. Media convergence is a theory in communications where every mass medium eventually merges to the point where they become one medium due to the advent of new communication technologies. This has also brought about a change in the dynamics of economy as distribution and cost structure is not the same in traditional media. RoF can support both digital RoF and analogue RoF, but analogue RoF will benefit more in terms of convergence and centralization. Crosstalk due to polarization rotation and MIMO transmission can be effectively solved based on advanced DSP algorithms, including the classic constant modulus algorithm [30]. RoF technology has been developed as an analogue solution that avoids digital components or extra processing overhead over fronthaul. A solid fronthaul design is the key approach to build efficient pipes between BBUs and users in terms of coverage, throughput, bandwidths, multi-service, quality, cost and compatibility with long-term convergence. All-band coverage and different service tiers. 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. (Online version in colour. The benefits of exploiting MMW for fronthaul transmissions include high capability of wireless data transmission, simple deployment and adaptive environmental suitability, as MMW bands provide multi-gigahertz available bandwidth without the burden of distant cable wiring. In some cases, mul… There are 3 types of media convergence: technological, economic, and cultural. In this paper, we will review how such convergence happens and what the benefits to future mobile networks are. Each RAU is virtually connected to all the BBUs in different pools. The convergence originates from fibre–wireless integration to macro- and small cells with multi-layer centralization and resource sharing, and results in seamless coordination among cells and services with accurate synchronization in future mobile networks. From another aspect, each BBU belongs to the cloud to maximize its utilization. However, in all generations so far, the network coverage is still composed of almost isolated cells. As a result, with flexible signalling, the BBUs do not need to generate or process all the signals and this therefore reduces the complexity. We use your LinkedIn profile and activity data to … None of the existing radio access technologies (RATs) will be able individually to provide the capabilities that effectively meet market demands. Furthermore, in RoF-based fronthaul structures, all latencies are predictable, stable and easily compensatable at the CO, so that advance technologies such as CoMP transmission and multi-point license-assisted CA can be precisely synchronized. OFDM has shown its good performance to combat multipath effects and inter-symbol interference (ISI), but it suffers from high peak-to-average power ratio (PAPR). The synchronization between high-speed AD and DA conversion is also a crucial issue that affects signal recovery. Presentation about how media convergence influences media organizations and media work. Convergence lead the media is more interactive and audience participation is encouraged. (Online version in colour. 1. These approaches can effectively reduce the signal baud rate as well as the required bandwidth for optical and electrical devices. Another ‘wall’ exists among current RAT standards. Mobile backhaul, midhaul and fronthaul in RANs. Discussion meeting issue ‘Communication networks beyond the capacity crunch’ organised and edited by Andrew Ellis, David Payne and David Saad. 60 GHz) provides very high-throughput coverage for minor-mobility indoor users. Many social media include a variety of functions. This includes newspapers, television, internet, magazines, radio etc. In typical WDM-PON systems, optical network units (ONUs) at subscriber ends (BSs in this case) require distributed transmitters, receivers and other passive components, which greatly increase the OPEX/CAPEX (ratio of operational expenditure to capital expenditure) as the number of BSs will grow dramatically in future high-density coverage. This infrastructure-sharing regime is realized by reconfigurable optical connections between the CO and fibre link interface. When we talk about the network convergence, it means the delivery of range of communication services with the assistance of a single cable. Photonic-assisted methods hold great potential to solve these challenges. Home; Explore; Successfully reported this slideshow. People get to bring out their hidden talents. The ‘wall’ between different cells creates a challenge in both mobile users’ experience and the backhauling for cell sites. This has also brought about a change in the dynamics of economy as distribution and cost structure is not the same in traditional media. At the RAU, the RF access equipment consisting of broadband O/E and E/O converters and RF components is shared by multiple operators and/or services from the same CO. Convergence lead the media is more interactive and audience participation is encouraged. )Download figureOpen in new tabDownload powerPoint, Figure 2. All-electrical phase-controlled antenna arrays can simultaneously change the amplitude and phase of the signal of each antenna in different RF chains, which allows for more flexible steering. 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). Media convergence is putting that book put onto your Kindle as another vehicle for content delivery, made into a movie, put on Audible, and even made into a video game for people to play with the story’s characters. Physical resources including laser sources, radio sources and peripheral equipment can be shared among different operators that provide multiple services [10,11]. In other words, RAU is a simplified version of RRH. Moreover, with the interactive World Wide Web, audiences are able to download and share music, video, photo via social networking and become media produce. This has also brought about a change in the dynamics of economy as distribution and cost structure is not the same in traditional media. 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]. On the other hand, the output from one BBU transmitter can be shared by multiple RAUs. This case raises important policy issues regarding howcountries encourage employment and new business start-ups.Senz has decided to manufacture in In this paper, we have discussed and reviewed the benefits of the convergence of fibre-optic-based optical access networks with RANs beyond the current bandwidth crunch. A CO centralizes functions for both macrocells and small cells, including baseband processing as well as radio signalling. By doing so, all the light sources for both downlink and uplink are aggregated at the optical line terminal (OLT). One contribution of 14 to a discussion meeting issue ‘Communication networks beyond the capacity crunch’. Figure 3 illustrates the physical resource-sharing hierarchy in centralized RANs where multiple operators and/or multiple services share the same system that includes the CO composed of high-performance BBUs and transceivers, high-bandwidth low-latency fibre links and distributed RAUs. Multi-tier heterogeneous cells with different frequencies converge to ubiquitous coverage in a mobile network. Enter your email address below and we will send you the reset instructions. …, ng is an oyample of computer sofhvara?C.​, Alfred north whitehead "in the garden of eden, adam saw the animals..." Related to the cone of experience, Give the methods of presenting the appetizer. The reconfiguration manipulated by the upper layers maintains the desired connections between BBUs and RAUs. Media convergence is important because it can enrich media content, increase media authenticity and produce better journalism (Zhang, 2008). When the Internet of things and media convergence interacted，social media expresses their competitive characteristics. …, Questions1. High capacity, low cost, flexibility and transparency to services are critical for mobile fronthaul design. Laptopsb. But with social media, they’re both working on things like Facebook, Instagram, and Twitter to get their messages out. There's so much customer data coming in that we even coined a whole industry, Big Data, to talk about it! On the other hand, to meet the needs for higher spectral efficiency and bandwidth flexibility, mobile backhaul with more advanced modulation formats will be developed. People get news daily through the media and this keeps them updated on the happenings around the world.3. Figure 3. All baseband functions and most RF signalling are realized in a CO, where resources are shared among all fronthaul links even if the links have various structures and serve different types of cells. Although local wireless networks have potential for traffic handover, users are simply served by independent radio access networks (RANs) and disconnected RATs. Meaning of convergence Convergence comes from the prefix con-, meaning together, and the verb verge, which … Moreover, with the interactive World Wide Web, audiences are able to download and share music , video , photo via social networking and become media produce. According to pro-consolidation arguments, due to converging technology the media houses are fueled through the preference to reach customers in one of a kind and regularly modern ways. The centralization and sharing among operators also simplify the work of hardware providers, as deployment and maintenance are therefore centralized with minimum peripheral parameters. Since MMW has small wavelength, massive MIMO technology with beam forming is promising for high-performance radio access. Arguably, there are a lot of benefits to this convergence of the two. The bandwidth requirement for higher wireless speed will grow beyond 100 Gb s−1 for a single access site. Convergence is the process where several media channels come together to exist and operate in synergy. This is the 21st century, and media convergence … The interference between cells that limits the system capacity can hardly be managed by isolated BSs. Easy. A phase antenna array is designed for this adaptive beam forming in different propagation conditions, including single-user and multi-user, line-of-sight (LoS) and non-LoS, static and mobile users. (Online version in colour.). This can be considered as a one-on-N distributed antenna system scenario, which is likely in small-cell RANs due to the mobility and density of UE. There is little space to further increase the transmission rate in these frequency bands. Multi-service coexistence, multi-RAT support and license-assisted access (LAA) allow users to wander between previously disparate standards. Mass Media refers to all forms of media that are open to and accessible by the public. Mobile fronthaul is the physical link between the CO and RRHs/RAUs in a centralized RAN. … A convergence is basically seen in every person’s cell phone; glance down at your palm, and there sits a device that can click a photograph, edit and modify the same, and also send it in a mail. Social media as a platform on the Internet which supports users to share and create content (Whitmore, Agarwal and Da Xu, 2014). In any case, high-frequency bands standing alone have inherent limitations to provide reliable control for mobile networks. This is a promising improvement over traditional CPRI systems, where digital processing takes variable delays. The convergence over mobile fronthaul itself plays an important role in the universal convergence of RANs. The centralized BBU and distributed remote radio heads (RRHs) are connected by digital fibre-optic links via standardized digital RF interfaces, such as common public radio interface (CPRI) and open base station architecture initiative (OBSAI) [8,9]. Figure 3. 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. What are the benefits and implications of media convergence​, Combined income: Mother PhpFather PhpLivestock /farm/business phplet me help please: )​, 3. Existing cellular systems operating below 6 GHz frequency bands are heavily used. The short answer is data. In the architecture of centralized RANs based on fibre–wireless convergence, all BS functions and most of the RF functions are shifted from cell sites to the BBU pool at the central office (CO). 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. In the next-generation 5G mobile communications, a large number of antennas are needed at the cell site in order to support antenna techniques such as massive MIMO (multiple-input multiple-output), and each antenna needs a high-capacity stream in the CPRI scheme. A digital photograph, for example, can be shot and circulated globally within seconds via the Internet. Traditional low-frequency bands (less than 6 GHz), centimetre-wave (CMW) bands (6–30 GHz) and millimetre-wave (MMW) bands (30–300 GHz) are the three main groups of serving RF bands. Nevertheless, media convergence is really good and is something that has contributed immensely to the media coverage and to the growth and development of our society at large. Besides, it also makes direct talk between services possible. Media Convergence Question on Quora – What is It? Published by the Royal Society. The authors are grateful for the support of a special infrastructure grant from Georgia Research Alliance and an education fund from the School of Electrical and Computer Engineering of Georgia Tech. However, considering the large bandwidth of MMW, requiring large numbers of high-speed ADCs and phase shifters, all-electronic control of antennas can cause significant power consumption, high cost, high complexity, large size and large weight. In terms of users’ experience, the future-proof approach achieves the goals of system capacity, link speed, latency and continuous heterogeneous cell coverage while overcoming the bandwidth crunch in next-generation communication networks. Explain the rationale to enter a mature market with asuccessful and established brand, the GustBuster®.​, what do you mean when we say culture is diverse​, elore each number.d 1. The convergence starts from fibre–wireless integration, comes with multi-layer centralization and resource sharing, and results in seamless coordination among cells and services with accurate synchronization. In this way, current and future mobile network standards such as 4G and 5G can coexist with optimized and continuous cell coverage using multi-tier RoF regardless of the underlying network topology or protocol.
