Patent number: 10123175Abstract: In some embodiments, a node associated with a distributed antenna wireless system obtains one or more combined receive signals responsive to a transmission by the wireless device. The distributed antenna wireless system comprises multiple Remote Radio Heads (RRHs) each comprising one or more receivers. Each receive branch of one or more receive branches of the distributed antenna wireless system comprises a combination of one receiver from each of the RRHs. The one or more combined receive signals comprise, for each receive branch, a combined receive signal that is a combination of signals received by the receivers comprised in the receive branch in accordance with different simultaneous ON/OFF patterns assigned to the RRHs for the receive branches. The node analyzes the one or more combined receive signals to determine information indicative of a geographic location of the wireless device.Type: GrantFiled: January 12, 2018Date of Patent: November 6, 2018Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Edwin Vai Hou Iun, Ping Liu

Patent number: 9491162Abstract: The present disclosure relates to systems and methods for controlling loss and theft of a radio equipment of a base station in a cellular communications network. In one embodiment, a radio equipment of a base station of a cellular communications network includes a radio subsystem configured to wirelessly transmit and receive radio signals for the cellular communications network, a local wireless interface, memory, and a controller. During commissioning of the radio equipment, the controller is configured to receive a physical location of the radio equipment and an access password for the radio equipment from a wireless device via a local wireless connection between the radio equipment and the wireless device established via the local wireless interface. The controller is configured to store the physical location of the radio equipment and the access password for the radio equipment in the memory of the radio equipment.Type: GrantFiled: August 21, 2013Date of Patent: November 8, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Robert Griffioen, Edwin Vai Hou Iun
