Patent number: 10645735Abstract: In some aspects, the disclosure is directed to methods and systems for an enhanced data rate, low energy wireless communication. Devices may communicate over predetermined wireless bands such as the 2.4 GHz and 5 GHz ISM bands, using ?/4-differential quadrature phase shift keying, with physical layer rates of 1, 2, 4, 8 Mbps or higher. Symbol timing may be at any frequency, and may be 256 ns in some implementations. In some implementations, to extend device battery life, devices may use a low latency reconnect mechanism allowing frequent hibernation or shutdown of transmitters and/or carriers.Type: GrantFiled: March 14, 2018Date of Patent: May 5, 2020Assignee: Avago Technologies International Sales Pte.

Patent number: 9185652Abstract: Disclosed are various embodiments of Bluetooth low energy (BLE) modules and methods implemented therein. An embodiment of the disclosure can obtain in a BLE module an advertiser packet transmitted by a BLE advertiser. An advertiser cache can be checked to determine whether the advertiser cache in the BLE module contains an entry associated with an advertiser address from the advertiser packet. The BLE module can determine whether a payload value of the advertiser packet has changed relative to a previous advertiser packet associated with the advertiser address. The BLE module can then suppress forwarding of the packet to a host processor and/or on-board processor executing firmware. The BLE module can also suppress sending a scan request packet back to the BLE advertiser.Type: GrantFiled: December 22, 2011Date of Patent: November 10, 2015Assignee: Broadcom CorporationInventors: Guoxin Xie, Yuan Zhuang, Angel Polo, Chikan Kwan, Cindy (Xin) Tian, Arthur Jin, Long Wang
