Huo David Di, Pittampalli Eshwar: Parallel optimization of wireless networks. Lucent Technologies, February 2, 2000: EP0977450-A2 (22 worldwide citation)

Signal markers (100-120) are placed in critical locations within the wireless network. Critical locations are locations where signals from base stations (10-22) may be weak due to natural or man-made obstruction and locations where user demand for network resources may be particularly heavy. The sig ...
