International Classification:

H04M 11/00

US Classification:

379 9327, 379 9326, 341173, 341 50

Abstract:

Systems, methods, protocols and apparatus for information exchange and synchronization using DTMF signaling over telephone communication channels are provided. Information is packetized and converted from one format, e. g. , ASCII formatted data, to another format, e. g. , BCD formatted data. The information is wrapped in one or more packets by a sending apparatus, each packet including one or more headers, such as a Name and Length field that identify the information being exchanged and the amount of data included in the packet payload/value field. The data in the packets are converted from BCD to DTMF signals and are transmitted over a telephone communication line to a receiving apparatus. The receiving apparatus converts the DTMF signals back to BCD formatted data and processes the packets to obtain the information contained therein.

International Classification:

H04W 52/02

US Classification:

370311

Abstract:

A method of saving power in a wireless network can include determining a plurality of stations associated with an AP. The AP can create station groups using group selection logic. Notably, the group selection logic is transparent to the plurality of stations. A plurality of TIMs can then be sent, each TIM allowing only one station group access to a channel during a predetermined time interval, such as a beacon interval. In another method, a station can determine its sleep duration based on at least one of first information from the TIM to generate random sleep duration, second information regarding previous operation of the station, and third information regarding a status of the station. The first, second, and third information can include the number of stations associated with the AP and having buffered data based on the TIM, historical collisions, and power status.

International Classification:

H04L 9/00

US Classification:

380255

Abstract:

Systems and methods are disclosed to improve performance of a communications device receiving encrypted communications from multiple sources. The communications device is configured to increase the amount of decryption performed using a hardware-based process as compared to a software-based process by reprogramming the hardware to store a shared security key corresponding to a frame received from a source, allowing the hardware-based process to decrypt subsequent frames from that source.

International Classification:

H04W 48/16

US Classification:

370338

Abstract:

Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.
