EMARIFLEX - Televic Rail

EMARIFLEX aims at further improve MAR technology, of which the foundation was laid in the research executed during the TRACK project. This innovative step is described more in detail in the remainder of this document. Basically, MAR2.0, as being referred to,

- enhances QoS,

- allows for real link aggregation,

- improves security,

- optimizes handover between wireless technologies (WiFi and cellular solutions) and

- adds LTE as wireless technology

The first goal of the proposed EMARIFLEX project is to prove and further optimize MAR2.0 technology in a realistic setting as being proposed in the FLEX project, with focus on testing LTE extensions. In the RAILS project, Televic Rail has executed real life tests on board a moving train. However, since the environment in such a test cannot be fully controlled (e.g. signal strength of WiFi access points in stations) and the repeatability of tests is almost impossible, a fully controllable and parameterizable test bed is essential. For the EMARIFLEX project W-iLab.t (iMinds) and NITOS (UTH) are valid candidates.

A second goal is the optimization of inter and intra technology handovers of MAR2.0, including LTE. Previous experiments revealed the rather poor support of intra-technology handovers in the available operating systems and driver software. Inter-technology handovers are supported by the MAR2.0 platform which is developed by Televic Rail to overcome these issues. First proof of concepts show positive results, although proper testing in a FLEX alike testbed is required before this technology can be rolled out to the field. This project will shorten go-to-market of this technology.
