A method for locating a source of interference external to a wireless telecommunications network includes establishing a grid of pixels that represents an area associated with a plurality of cellular antennas, assigning an elevation value to each pixel in the grid, determining a vertical gain for each of the plurality of cellular antennas, and determining respective probability values for pixels in the grid using the elevation values and the vertical gain, each of the respective probability values representing a probability that the source of interference external to the wireless telecommunications network is located at an associated pixel.

A method for balancing inroute traffic load that contains both guaranteed QoS and best effort traffic. Hierarchical grouping levels are defined with the lowest level corresponding to inroutes within the system. Certain levels have common symbol rates, modulation rates, or both. When a new terminal requires admission, it is assigned to entries in the different hierarchical levels so that the inroute traffic load across all levels are balanced. Terminals are admitted to inroutes based, in part, on their channel quality indicator. Inroute traffic load can periodically rebalance based on elapsed time or terminal redistribution.

A System and Method is provided that enable identifying cyber security attacks using observation and monitoring of end point activity. By following and monitoring the wireless connection related activities of endpoint devices as they cycle through various steps leading to establishing a connection to the secure network, a knowledge base is established in the cloud by analysis of the actions, and communication to build the confidence that the users of the network are where they should be. In one embodiment, no access is provided until a user presents valid credentials. Based on these credentials the network then builds a specific path based on access controls, tunnels or other techniques to control the user's communication and access to specific targets within the network.
