The Technology behind IRAP

the BIC-IRAP-System is characterized by its multi-operator-capability and the usage of multi-mode Small-Cells. Due to the opportunity to provide simultaneously voice- and data-services of different telecommunication and ISPs by one single platform, a top-quality network coverage for every user can be obtained. The multi-mode-feature of the small-cells enables the system to provide a dynamic as well as demand-actuated emission of the radio signals in different frequency domains, from Wireless-LAN to LTE.
For the authentication of the user devices, BIC-IRAP counts on the features of the modern, standardized Hotspot 2.0 -approach. This makes a seamless Wireless-LAN-Roaming possible, similar to classic cellular mobile communications systems. The inconvenient, multistage user input of SSID and login data on portal pages is no longer required. Thus, the effort of interaction of the users is reduced to a minimum.
The installation of BIC-IRAP-System is done by specialised service enterprises, which carry out a customized planning of the installation with the aid of self-developed planning standards.

To adapt the installation of the BIC-IRAP-System optimally to the individual needs of the customer, a multi-layer radio network planning takes place. This comes with a determination of the ideal deployment of the small cells by the use of established 3D-radio dispersion models and multi floor models, to ensure a gapless and needs based coverage inside the building. Nevertheless, an existing BIC-IRAP can be extended in a cost efficient way.

{slider=Software defined networking and virtualised network functions}The use of SDN- and NFW-methods in the field of the core-network-functions allows the roll-out of a BIC-IRAP-System, in which the essential functions are carried out by software in a central datacentre. Thereby a flexible, customer specific adjustment of the range of its functions becomes possible. In addition to the basic provision of voice- and data services as well as the quality of service and mobility management, individual functional enhancements such as Wireless-LAN-functions become imaginable.

To adjust the resource allocation of the BIC-IRAP network dynamically to the amount of users and the flow of traffic inside the building, IRAP includes a broad online network management system. This contains prediction techniques for the connection- and data traffic volume to be expected as well as the corresponding load- and QoS management.

Most of the network management functions will be implemented as virtualised network functions by the use of datacentre capacities. This generates synergies and reduces the local hardware requirements in the premises. A high availability of the services can be obtained (along with redundancy mechanisms in the datacentre), as well as short term dynamically changes of the system capacities become possible. For the facility management and the MISP, cost efficient operation of the system and future viability of the installed hardware will be ensured. The dynamic network (re-) configuration as well as the integrated load- and QoS-Management guarantee an optimal provision of mobile internet for the user.

A special feature of BIC-IRAP is the network access and handover-handling. Based on the measurement of key performance indicators (KPIs) and different prediction procedures, the allocation of user devices and radio cells can be optimised. Thereby an optimal load balancing of the LTE/Wireless-LAN cells and the allocation of the available radio frequencies can be obtained. This guarantees the best possible transmission rates and QoS from the user perspective. The available backhaul capacity can be utilized and frequent switching of the mobile devices between the radio cells can be prevented.
Efficient operation of a radio based network requires the minimization of radio interference. Therefore, special multi band interference management processes are developed in BIC IRAP. Moreover, the interference management guarantees that only the amount of energy is used that is needed to serve the actual demand of the users and that is needed to ensure the upkeep of the network.
