From the time of its conceptualization, Long Term Evolution (LTE) has been positioned as a distributed and flat architecture whose strength lies in its simplicity. However, it wasn’t long before tech titans started acknowledging the benefits, perhaps even the need, for centralization in the LTE stack even if it violated the initial premise. This is where Cloud RAN, also referred to as C-RAN or Centralized RAN, brings value to the table. Wikipedia defines C-RAN as “[A] centralized, cloud-based architecture for radio access networks that supports 2G, 3G, 4G and future wireless communication standards”. C-RAN comprises centralized baseband units (BBU) and distributed remote radio heads (RRH) connected through high-capacity, low-latency links. Put more succinctly, the C-RAN architecture involves splitting the baseband processing between RRH and BBU functions, preferably running the latter on commodity servers in a virtualized environment with the intent of optimizing cost while offering easily-scalable solutions.
Public safety is one of the major area of interest for governments around the world. In the modern world, technology touches and changes our lives continuously. Everyone wants to be connected all the time and new technologies like LTE, Wi-Fi etc play important roles. Almost everyone has a good quality smartphone and the penetration of smart phones is increasing on a daily basis. This leads us to think of requirements for Public Safety Systems (PSS) and redefine the already existing PSS.
During this year's Mobile World Congress in Barcelona, RCR Wireless stopped by our hospitality suite and interviewed Shrikant Latkar, VP of Products and Solutions Marketing, to find out more about the Aricent Group. In particular, they wanted to discuss our landmark of hitting 35 LTE deployments around the world, and the work we have been doing in small cells (Femtocells) with a variety of partners.
Aricent recently conducted a webinar on the topic of MPLS-Transport Profile. We had several hundred people participate and they asked more questions than we were able to answer in the time we had! Here are answers to the ones we didn't get to in the webinar.
2011 marks the 10th anniversary of Carrier Ethernet services launched by the Metro Ethernet Forum (MEF). The technology has penetrated deep into global communication businesses, both as a service and as a network infrastructure cornerstone, with the entire business ecosystem investing in this technology. Here are a few statistics that show just how deep the services have been integrated.
Operators today are involved in a vicious cycle of adding bandwidth in order to support bandwidth hungry applications, which in turn is spawning even hungrier applications. This is driving operators to deploy next generation technologies such as LTE, which is proving to be one of the biggest “spends” in the history of telecommunications. The problem is that the operator’s Average Revenue Per User (ARPU) is not increasing at the same rate as the demand for mobile broadband, driving the need for operators to innovate to maximize revenue and optimize CAPEX and OPEX.
