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.

平均智能手机或平板电脑至少有10 GB的内存可用。非常粗略地说，这相当于2,000分钟的高清（HD）视频，即几乎1.5天的视频内容可用（内存芯片尺寸缩小，价格大幅下降）。对于新闻应用程序或短视频剪辑，这意味着普通的移动终端是一个小型的、始终在线的、始终连接的移动的数据中心。Fluentic正在开发解决方案，以利用一小部分移动的用户的空闲内存，以便传播流行的智能手机应用程序的内容（例如，诸如BBC、Sky、iTV、The Guardian的内容提供商）发送到已经安装了该应用的附近的每个设备。内容提供商主动地将内容推送给选定的移动的用户（“源”）。然后，源将内容传播给对相同内容感兴趣的其他用户（“目的地”）。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实现同步。当两个设备都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，源和目的地配对。内容分发以设备到设备（D2 D）、点对点（P2P）方式进行，独立于蜂窝连接。因此，连通性和数据上限的挑战并不是分发大量数据的障碍。
