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.
Vehicle to everything technology (V2X) is one of the much watched for technologies in the current connected everything scenario and is expected to make driving simpler, easier, richer, safer, greener and more. V2X communications and related solutions will help communication possible between the vehicle and everything else – V2I (Vehicle-to-Infrastructure), V2V (Vehicle-to-vehicle), V2P (Vehicle-to-Pedestrian), V2D (Vehicle-to-device) and V2G (Vehicle-to-grid) et al. V2X is touted to increase road safety, better flow of traffic, save energy and disburse relevant location related information.
Over the last 4 decades, mobile networks have evolved across four generations. After witnessing the growth of 4th generation technology popularly known as 4G, now we are at the verge of experiencing the next, i.e., the 5th generation of wireless technology.
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.
NFV (Network Function Virtualization) is a transformative technology whose advent has been highly anticipated for 3 years now. NFVManagement and Orchestration (NFV MANO), in turn, is the heart and brain of the NFV architecture. In this blog, I’ll start with a high level description of the NFV MANO architecture followed by challenges that the industry faces in adopting this architecture.
