Disclosed herein are embodiments including a modular base station that is, for example, easily deployable in emerging markets. The modular base station is designed to be easily transported and affixed, for example, to poles or trees. The modular base station is designed to withstand high temperatures caused by operating at high altitudes and to be easily configured, oriented, and serviced in the field. Its components (e.g., radio frequency (RF) circuit boards) are modular so as to interoperate with various third-party compatible devices.

Systems and methods for automatically configuring a distributed antenna system are provided. A configuration sub-system of the distributed antenna system can identify signal parameters for downlink signals received from one or more base stations via inputs of a unit in the distributed antenna system. The configuration sub-system can automatically determine a configuration plan for the distributed antenna system based on the automatically identified signal parameters. The configuration plan specifies how to combine subsets of the downlink signals for routing to remote antenna units of the distributed antenna system.

The present invention refers to a method and apparatus and computer program for detecting communities in a radio access network with a plurality of vertices (C, BBU), wherein the method comprises calculating (S11) relationship strengths (31, 41) for network connections between the vertices (C, BBU) by executing a connection strength calculation process by analyzing performance factors, decisive for network performance including cell coverage overlap, signal strength, and inter-cell interference. The method further creates (S12) a network graph with nodes, representing the vertices (C,BBU) in the network and edges, representing the network connections based on the calculated relationship strengths (31, 41) and applies (S13) an extended iterative disjoint community detection algorithm for clustering nodes into communities, wherein in each iteration imposed one or more constraints for clustering cooperating nodes into the same community are analyzed (S14).

A system and method for improving a network topology to minimize load imbalance and latency between network nodes is provided. A network performance and configuration tool receives performance data from payload handling nodes, including radio stations, transport nodes and payload gateways to calculate a current network condition related to the current network topology. A revised network topology is determined by selecting a radio station to re-home from its parent transport node and payload gateway to a newly selected transport node and payload gateway. The revised network condition is calculated and compared to current network condition to determine if the re-homing should be accepted. The process can be repeated for a number of iterations until an optimized network topology is found. Configuration instructions are then transmitted to any radio stations that have been re-homed in the final network topology.
