Abstract: In User Equipment (UE) at various geographic locations, circuitry exchanges TCP packets with radios, and the radios wirelessly exchange the TCP packets with wireless communication nodes. The circuitry determines TCP retransmission rates for the radios at the geographic locations. The circuitry estimates TCP retransmission rates for the radios at a new geographic location based on the TCP retransmission rates for the radios at the past geographic locations. The circuitry selects one of the radios based on the estimated TCP retransmission rates at the new geographic location. At the new geographic location, the circuitry exchanges new TCP packets with the selected one of the radios, and the selected one of the radios wirelessly exchanges the new TCP packets with one of the wireless communication nodes.

Abstract: A mobile User Equipment (UE) uses Transmission Control Protocol (TCP) to deliver mobile data services over different radios. The mobile UE qualifies the individual radios that have adequate signal strength at a geographic location. The mobile UE estimates TCP retransmission rates at the location for the qualified radios. The mobile UE identifies individual qualified radios that have adequate TCP retransmission rate estimates. The mobile UE selects one of the identified radios that has the lowest power usage. The mobile UE exchanges TCP packets over the selected radio which includes participating in TCP retransmissions at the location. The selected radio wirelessly exchanges the TCP packets with a wireless access node. The mobile UE stores resulting TCP retransmission data for the selected radio in association with the location for future TCP retransmission rate estimates.

Abstract: Embodiments disclosed herein provide systems and methods for unlocking a wireless communication device into an operating mode based on RFID element information. In a particular embodiment, a method provides locking a user interface on the wireless communication device. The method further provides receiving a wireless signal from a first Radio Frequency Identification (RFID) element and responsively determining if the wireless signal comprises a valid unlock instruction. If the first signal comprises the valid unlock instruction, then the method provides selecting one of the operating modes for the wireless communication device, unlocking the user interface on the wireless communication device, and operating the wireless communication device in the selected operating mode.

Abstract: A water resistant port and a method for using it are provided. The port comprises a moveable seal assembly coupled to a spring structure. The moveable seal assembly may comprise a plastic material on an inner surface and a seal material on an outer surface. When the spring structure is in a relaxed position, the moveable seal assembly is caused to create a seal with a gasket material coupled to a side wall of a port casing. The spring structure comprises a spring coupled to the moveable seal assembly at one end and to a guide at an opposite end in an interior portion of the port casing. The port casing comprises, on an interior surface, one or more electrical connectors adapted to receive one or more electrical contacts of an accessory plug when the spring structure is compressed and the moveable seal assembly is in an engaged position.
