Heterogeneous network (HetNet) deployment strategies are one of the options that can be used to reduce the power consumption in wireless mobile networks, particularly in those scenarios where the capacity requirements over a geographical area are not uniformly distributed. The key rationale behind this technique is to tailor the network deployment to the expected traffic levels, i.e., to provide coverage via macro base stations and to guarantee high capacity only where it is needed via, micro, pico and/or femto cells (Figure 1).
Mobile payment services have been used many years in developing countries where the mobile operators provide financial services based on the mobile phone subscriptions and money loaded onto pre-paid accounts. The Mobile operators provide financial services to the majority of the population that in these regions normally do not have credit card or bank accounts. Mobile operators are key actors for providing these payment and banking services to the “unbanked”.
The term “smart grid” refers to a two-way communication network for electricity grid where devices wirelessly connected are able to remotely detecting status of electricity generations, transmission lines and substations, monitoring consumption of user electricity usage, adjusting the power consumption of household applications to conserve energy, and reduce energy losses.
A DTN/WSN infrastructure for data distribution and environmental monitoring in communication challenged areas
This project aims at tapping of data from isolated Wireless Sensor Networks (WSNs) using infrastructureless communication services such as Delay Tolerant Networking (DTN. The target scenarios are remote sensor networks located in isolated areas with very limited possibilities for communication with the surrounding world.
The gDAS project targets to characterize how energy consumption for future DAS (Distributed Antenna Systems) “Front Haul” relates to traditional networks with “Back Haul” fiber transmission to each radio base station. So called FDAS (Fibre DAS based) networks are in focus for the study.
Self Organizing Networks (SON) is a set of solutions developed to automate the configuration, optimization and healing of a wireless network. Today SON uses a number of radio network and configuration parameters to optimize a wireless network but the use of antenna tilt is still under study.
In the project, we shall investigate how network coding can increase the reliability and flexibility, and decrease network traffic and delay of distributed storage and content dissemination in heterogeneous mobile networks, where user terminals have limited storage space and bandwidth. Through the Deviceto-device and cloud storage technology, the efficiency of media storage and dissemination can be significantly increased. The network coding can allow the maximum (capacity-achieving) flow, flexibility and security.
The use of on-board passenger internet on trains is steadily increasing and today passenger surveys show that it is more important that the on-board wireless internet is functioning than that the train is on time!
Today the most common solution to provide speech and 2G/3G connectivity on board trains is with the help of simple 2G/3G amplify-and-forward repeater systems. However, increasingly train operators in Europe are more and more often using a system’s solution (provided by icomera) that enables simultaneously connectivity with multiple radio carriers at different frequencies, standards and by different operators.
Trusted Service Management for a Multitude of Multitudes – TSM MoM
Mobile payment services and “mobile wallet” applications based on Near Field Technology (NFC) has been discussed for some years. The combined service and business development involves a number of challenges related to cross-industry communication and creation of new business roles and collaboration between companies. Business and cooperation models are important, especially when new services involve companies, sectors and industries that previously have not been involved or engaged in each other businesses or sectors.
