Augmented reality is another area of interest for Bell Labs.
The system pictured above, called Dekaps, is being developed by the labs. It displays information associated with the image picked up by a smartphone's camera or uses the orientation of the phone itself to identify tagged things nearby and show information about them. As with other augmented reality systems such as Layar, Dekaps can provide not only location-based information but also a virtual layer of information based on the recognition of an image.
In this picture, a user is training an iPhone's camera on a picture that is recognised by Dekaps, which then overlays a dancing animated robot. This technology could be used to enhance printed advertising.
This prototype optical coupling, which is the interface between the fibre-optic cable and the circuitry, can transmit data at 100Gbps. According to Bell Labs researcher Jean Godin, the same technology could lead to transmissions of 400Gbps over "hundreds of kilometres".
Bell Labs is working on what it calls 'small cells'. Such cells are derived from femtocell technology, which offloads 3G data onto a fixed network so as to reduce the strain on the mobile network.
Small cells would be deployed in high density, along with a new protocol called Not-Mobile IP (NMIP) that is designed to simplify the network. NMIP links terminals such as mobile phones directly with servers, cutting out the need for tunnelling and reducing the network itself to simple switches. In this demonstration, video streaming was maintained despite simulated handover between IP addresses.
