Coexistence of 3G Repeaters with LTE Base Stations

Coexistence of 3G Repeaters with LTE Base Stations

Repeaters have been an attractive solution for mobile operators to upgrade their wireless networks at low cost and to extend network coverage effectively. Since the first LTE commercial deployment in 2009, many mobile operators have launched LTE networks by upgrading their 3G and legacy networks. Because all 3G frequency bands are shared with the frequency bands for LTE deployment and 3G mobile...

Development of Array Antenna for LTE Small Cell Base Stations

Mobile service providers in recent years have been facing rapid increases in data traffic, so have much interest in small cell base stations such as picocells and femtocells. However, these small cell base stations are recognized as potential causes of inter-cell interference, since it is highly probable that they will be deployed using the same radio frequency as used by macrocells, due to the...

Context based configuration management of plug & play LTE base stations

In second and third generation cellular networks the rollout of base stations needs to be conscientiously prepared, because their radio configuration should match with the coverage provided by existing cells in their neighborhood. The detailed radio planning for every new cell requires considerable human resources and time. This paper proposes a framework for 3G Long Term Evolution (LTE) that c...

Minimum cost solar power systems for LTE macro base stations

This paper proposes an algorithm for the identification of the minimum cost solution over a 10 year time horizon to power an LTE (Long-Term Evolution) macro base station, using a photovoltaic solar panel, a set of batteries, and optionally also a secondary power source, which can be a connection to a (possibly unreliable) power grid, or a small Diesel generator. The optimization is formalised a...
