Abstract: A method includes determining, at a server associated with a wireless communications network, a first set of multimedia content items to be transmitted via a multimedia broadcast multicast services (MBMS) broadcast transmission to multiple devices. The first set of multimedia content items may be determined based on a data traffic profile of the wireless communication network. The server may select a particular node of the wireless communications network to transmit the first set of multimedia content items via the MBMS broadcast transmission. The method also includes determining a second set of multimedia content items to be transmitted from the selected node to a particular device via a unicast transmission. The second set of multimedia content items may be determined based on a content request profile associated with the particular device.

Abstract: A cell site includes a tower and a power over Ethernet system to power devices on the tower. The power over Ethernet system includes a power over Ethernet switch and a multiplexing box. Ethernet cables connect output ports of the power over Ethernet switch to input ports of the multiplexing box. A power plant is connected to the input of the power over Ethernet switch. Devices are connected to the output ports of the multiplexing box. The power over Ethernet system also includes a power management control.

Abstract: In determining whether to provide an alert associated with a mobile element to a mobile communication device, speeds and directions of travel of the mobile element and the mobile communication device are determined. A relative location of the mobile communication device is calculated with respect to the mobile element. Based on the relative location of the mobile communication device with respect to the mobile element, a determination is made whether the alert should be provided.
