The optimisation of an in-building distributed antenna system (DAS) has traditionally been a function of coverage and capacity. A third consideration has come into play with the increased capacity demand created by new generation mobile technologies – an essential requirement to future-proof the system and ensure coverage for a variety of wireless technologies.

To provide throughput in LTE networks it is essential to reduce the link loss between the eNodeB and the Mobile. For Hot spots and smaller areas this can be achieved in an easy way by using off air repeaters on a MIMO network.

The challenge for this project was to implement a VHF and digital wireless system for the national Austrian railway operator ÖBB (Österreichische Bundesbahnen). We worked with Kapsch CarrierCom to work with a completely redundant public safety and cellular system and bring it up to date to provide reliable coverage.

Repeaters are used to provide coverage for mobile devices within an area that is isolated from the mobile network, for example the inside of a building or train. The IMOP algorithm is part of the digital signal processing for the repeater, and can help identify when isolation margins have become low.
