BMW presents the Vehicular CrowdCell at the Mobile World Congress 2016 in Barcelona. Mobile femtocells help to optimize future mobile radio networks
At this yearâs Mobile World Congress in Barcelona (22 â 25 February 2016) â which stands alongside the IFA in Berlin as Europeâs most important mobile communications show â the BMW Group is unveiling the research project âVehicular CrowdCellâ.
This project extends the concept of the âVehicular Small Cellâ presented last year in Barcelona. While the âVehicular Small Cellâ is a mobile femtocell that optimises the mobile radio reception inside vehicles, it is now also capable to enhance the capacity and coverage of mobile radio networks.
The BMW Group is teaming up with peiker and Nash Technologies to present a prototype of the âVehicular CrowdCellâ integrated into a BMW research vehicle.
The rapid growth of mobile data traffic, e.g. due to the increasing use of multi-media services such as music or video streaming with mobile devices, requires even more powerful mobile radio networks in the future.
One strategy to increase the capacity and coverage of future networks is the integration of a large number of small cells and relays in addition to the existing base stations.
In 2015 the BMW Group, together with its partners peiker and Nash Technologies, presented the worldâs first mobile femtocell in a vehicle.
The âVehicular Small Cellâ optimises the reception available to mobile devices inside vehicles via the vehicleâs aerial. Now the concept has been extended to create the âVehicular CrowdCellâ. Based on data traffic and coverage demands, the mobile femtocells are dynamically activated to locally enhance mobile radio networks.
The benefits of Vehicular CrowdCells in practice
One possible application of âVehicular CrowdCellsâ are car-sharing fleets â in particular with electric vehicles. Here, a large number of vehicles spread over cities and regions could serve as local radio relays when parked.
If one or more users are located close to a mobile femtocell, it is activated on demand in order to increase the bandwidth or provide additional network coverage.
In such a way, the performance of the existing network can be dynamically optimized. Benefits for mobile phone users in hotspots include a higher data rate and the absence of reception white spots â especially in areas where the signal coverage is low.
âThe âVehicular Small Cellâ will optimise in-vehicle connectivity of mobile devices for our customers,â explains Dr. Peter Fertl, project manager at the BMW Group. âAt the same time, the integration into a network of âVehicular CrowdCellsâ will enable the ubiquitous and seamless availability of high-quality mobile radio connections outside the vehicle as well.â
The BMW Group has long been one of the worldâs leading carmakers when it comes to the connectivity of drivers, their vehicles and the outside world. The company has been working continuously on the development of pioneering digital services alongside its innovative BMW ConnectedDrive services.
The research project âVehicular CrowdCellâ lays the foundations for improving connectivity inside the vehicle and beyond.
