An average smartphone or tablet has at least 10GBs of memory available. Very roughly, this corresponds to 2,000 mins of High Definition (HD) video, that is almost 1.5days worth of video content readily available (with memory chip sizes shrinking and prices falling sharply). For news applications, or short video clips, this means that the average mobile device is a small, always on, always connected and mobile data-centre. Fluentic is developing solutions to exploit the spare memory of a fraction of mobile users in order to disseminate content of popular smartphone applications (e.g., content providers such as BBC, Sky, iTV, The Guardian) to every device in the vicinity that has got the application installed. Content providers proactively push content to selected mobile users (the “sources”). Sources then disseminate content to other users that are interested in the same content (the “destinations”). Sources and destinations sync through our unique, information-centric connectivity software solutions. Sources and destinations pair when both devices have the same application installed and the source nodes have updated content to disseminate. Content distribution takes place in a Device-to-Device (D2D), Peer-to-Peer (P2P) manner, independently of the cellular connection. Therefore, challenged connectivity and data caps are not a barrier to the distribution of large volumes of data.

普通智能手机或平板电脑至少有 10GB 可用内存。粗略地说，这相当于 2,000 分钟的高清 (HD) 视频，相当于几乎 1.5 天可用的视频内容（内存芯片尺寸缩小且价格急剧下降）。对于新闻应用程序或短视频剪辑来说，这意味着普通移动设备是一个小型、始终在线、始终连接的移动数据中心。 Fluentic 正在开发解决方案，以利用一小部分移动用户的空闲内存，将流行智能手机应用程序（例如 BBC、Sky、iTV、The Guardian 等内容提供商）的内容传播到附近安装了该应用程序的每台设备。内容提供商主动将内容推送给选定的移动用户（“来源”）。然后，源将内容传播给对同一内容感兴趣的其他用户（“目的地”）。来源和目的地通过我们独特的、以信息为中心的连接软件解决方案进行同步。当两个设备安装了相同的应用程序并且源节点具有要传播的更新内容时，源和目标配对。内容分发以设备到设备 (D2D)、点对点 (P2P) 方式进行，独立于蜂窝连接。因此，受到挑战的连接性和数据上限并不是大量数据分发的障碍。
