The estimation of the coverage area of a single transmitter in a microcell environment with irregular distribution and elevation of buildings is investigated in this paper. Two methods were applied to compute the coverage area of five locations of a test transmitter. The first method corresponded to a simple thresholding of the estimated path loss values(More)
A walk test is a tedious and time consuming task for mobile network operators, typically required to verify signal levels and quality of service provided by a newly deployed cell site. The resources spent in such tests can be reduced with the use of accurate planning and designing tools. In this paper, we describe and validate an LTE/LTE-A downlink(More)
In this paper, we propose a distributed load balancing algorithm with adaptive bias adjustment for LTE/LTE-A HetNets. We have formulated the problem as a local sum utility maximization. The distributed algorithm is capable of fairly distributing the load among base stations with a minimum level of coordination. The performance of the algorithm was evaluated(More)
