Due to emerging new digital technologies and high-definition multimedia formats the bandwidth demand of end users is continuously increasing. For fixed users the main access networks are usually still wired networks variants, but technologically advanced wireless networks also strive to satisfy this demand while having a natural monopoly in case of mobile users.
Currently the 5th Generation of mobile networks is being standardized with commercial launch of operators expected from late 2018, first concentrating on enhanced Mobile Broadband as the main use case. These new networks will coexist with earlier mobile network for years, resulting in a need for resource distribution strategies which are looking into cases where multiple mobile accesses in place.
This work investigates a case where 4G and 5G networks coexist in a suburban environment in a setup optimised for enhanced Mobile Broadband. The main contributions are the modelling and simulation of such environment and a direction-aware strategy where 5G massive MIMO beamforming and carrier aggregation technologies are used to distribute radio resources in a way that user satisfaction would be maximised.
Using Java-based simulation, the performance of the strategy is then compared to a non-trivial strategy where the above directional logic is not present.
