The reconfiguration manipulated by the upper layers maintains the desired connections between BBUs and RAUs. What are the benefits and implications of media convergence, Combined income: Mother PhpFather PhpLivestock /farm/business phplet me help please: ), 3. …, China rather than TheNetherlands. 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. When the Internet of things and media convergence interacted，social media expresses their competitive characteristics. One contribution of 14 to a discussion meeting issue ‘Communication networks beyond the capacity crunch’. 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. Enter your email address below and we will send you the reset instructions. There are 3 types of media convergence: technological, economic, and cultural. Besides, it also makes direct talk between services possible. Benefits of Media Convergence: The content creators can use the platform to generate customized content that is targeted at a specific group. Mass Media refers to all forms of media that are open to and accessible by the public. The content creators can use the platform to generate customized content that is targeted at a specific group. Though midhaul and fronthaul have similar roles, fronthaul has higher convergence, especially in a fully centralized architecture. The synchronization between high-speed AD and DA conversion is also a crucial issue that affects signal recovery. The five major elements of media convergence—the technological, the … (Online version in colour.). 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. Second, considering the mobility of users, they should support dynamic multi-direction signal delivery . Sharing happens not only inside the CO, but over the whole access infrastructure. Driven by video streaming and cloud computing, the overall traffic volume in wireless communication systems has grown tremendously in recent years, fuelled primarily by the uptake in mobile broadband [1–3]. This trend is expected to continue into the 5G era in 2020 in the roadmap of 3GPP (the 3rd Generation Partnership Project) . 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 . Figure 5. Benefits of Media Convergence: The content creators can use the platform to generate customized content that is targeted at a specific group. 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. 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. 2.4/5 GHz, LTE-U) to provide hot-spot coverage, while the high-frequency small cell (e.g. 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. 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. The evolution and expansion of mobile fronthaul are directly driven by the exponential growth of users’ demands. Photonic-assisted methods hold great potential to solve these challenges. A multi-structure mobile fronthaul provides system resilience, flexibility and increased overall bandwidth capacity. This includes newspapers, television, internet, magazines, radio etc. What, if anything, can governments do toencourage manufacturing at home?, 2. 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. In addition, RoF facilitates the generation and distribution of high-frequency signals in optical approaches, as high-frequency signalling burdens fronthaul systems much more than low-frequency microwave signals . This convergence should break these ‘walls’ and merge all the isolated lanes into a super-speed highway that reaches all users in ubiquitous coverage, as shown in figure 1. With technological convergence, the electronic transmissio… However, they still require high-speed DA/AD (digital-to-analogue/analogue-to-digital) converters at BSs, which will reduce the network scalability and tremendously increase the cost. Benefits of Media Convergence: The content creators can use the platform to generate customized content that is targeted at a specific group. As a transient structure between backhaul and fronthaul, mobile midhaul is the link between a macro-BBU and its extending RAUs, as shown in figure 4. The sharing in this level may include communications between operators inside the CO, which greatly reduces the core network traffic and improves the efficiency of common services supplied by multiple operators.
