  • Patent number: 8625584
    Abstract: A smart card is used with a network based system to providing portable telecommunication and computing services. In an exemplary embodiment the smart card holds a user authentication code and user telephony account information. The smart card transfers the user authentication code and the account information to one of a plurality of geographically dispersed card readers which are each connected to a local telephony device. When the smart card is plugged into a first card reader, telephone calls directed to the smart card user's follow-me telephone number are received at a first local telephony device. When the smart card is plugged into a second smart card reader, telephone calls directed to the follow-me telephone number are received at a second telephony local device. Hence the user is enabled to receive and place calls using any of the geographically dispersed telephony devices as though they were his/her own personal landline or cellular telephone supplied by his/her telephony services provider.

  • Patent number: 8599809
    Abstract: In the wireless mesh network including a sender, a receiver, and a plurality of access points disposed between the sender and the receiver, available transmission paths between the sender and the receiver are determined; transmission expected values are calculated for the transmission paths; and a transmission path having a minimum transmission expected value is set as an actual transmission path. The transmission expected value is a sum of expected transmission counts, which is a reciprocal of multiplication of forward transmission success rate and backward transmission success rate of a communication link between the nodes disposed on the transmission paths. When an access point can transmit a packet concurrently with another access point, the expected transmitted count is reduced by half.

  • Patent number: 8582536
    Abstract: Methods and apparatus for providing channel diversity to wireless terminals (WTs) in a manner that reduces the latency between the time a WT encounters satisfactory channel conditions are described. A plurality of communications channels with different physical characteristics are maintained in a cell by a base station (BS). Each WT monitors multiple channels and maintains multiple channel estimates at the same time so that rapid switching between channels is possible. Channel quality information is conveyed from each WT to the BS. The WT or BS selects a channel based on the measured channel quality. By supporting multiple channels and by introducing periodic variations into the channels in various embodiments, the time before a WT encounters a channel with good or acceptable channel conditions is minimized even if the WT does not change location. Multiple antennas are used at the BS to support numerous channels simultaneously, e.g., by controlling antenna patterns.
