20140323087 | NETWORK ACCESS SELECTION BETWEEN ACCESS NETWORKS - WiFi/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and Wi-Fi cells. Cellular network cells providing overlapping coverage with Wi-Fi cells are correlated with the Wi-Fi cells. A received signal strength threshold is determined for each Wi-Fi cell based on an average throughput of the cellular network cells correlated with the Wi-Fi cell. The WiFi user terminal admit threshold is used to control the effective coverage of the Wi-Fi cell. A user terminal operating within a cellular network cell is admitted to a Wi-Fi only if it is within the effective coverage area of the Wi-Fi cell as determined by the received signal strength threshold. Increasing the threshold shrinks the effective coverage area of the Wi-Fi cell to allow user terminal only of strong RSSI to make connection to the WiFi Cell, and steers user terminal of weak RSSI away from the Wi-Fi cell. In contrary, decreasing the threshold expands the effective coverage area of the Wi-Fi cell and effectively allows more user terminal making connection to the Wi-Fi cell. | 10-30-2014 |

20100159971 | AUTOMATIC ANTENNA SELECTION FOR MESH BACKHAUL NETWORK NODES - Methods and devices related to wireless networking. A wireless device has multiple directional antennas and multiple backhaul radio modules which provide point to point wireless links with other wireless devices. Each radio module can use any one of the available directional antennas to link to one other routing device. Antennas are automatically selected for each wireless device by merely setting one device in a “hunt” mode and setting another device in a “listen” mode. Devices in a hunt mode cycle through the available antennas by sequentially transmitting transmit messages to devices in the listen mode using each of the available antennas in turn. Devices in the listen mode also cycle through their available antennas by sequentially “listening” for transmit messages. A listen mode device, receives transmit messages on each of its available antennas, and, after gathering the relevant data, determines which of its antennas is best suited for communicating with the hunt mode device. The listen mode device antenna which is best suited is then used to transmit a response message to the hunt mode device. This listen mode device antenna is thus configured for communicating with the hunt mode device. Similarly, when the hunt mode device receives the response message, it designates its antenna which transmitted the transmit message as being configured for communications with the listen mode device. | 06-24-2010 |
