Mobile phones are two-way microwave radios that also emit low levels of electromagnetic radiation. Inconsistent results have been published on potential risks of brain tumors tied with mobile phone use as a result of important methodological(More)
In this paper we consider a wireless network, where each transceiver is equipped with a directional antenna, and study two direction assignment problems, determined by the type of antennas employed. Given a set S of transceivers with directional antennas, located in the plane. We investigate two types of directional antennas — quadrant antennas and(More)
