摘要： A method for managing one or more wireless connections includes: conducting a plurality of scan operations and a plurality of connection operations. Each scan operation is conducted within one of a plurality of scan windows, and each connection operation is conducted within one of a plurality of connection windows. The scan windows and the connection windows do not overlap with each other. Consecutive scan windows are separated by a scan interval, which is a first integer multiplication of a minimum interval, and consecutive connection windows are separated by a connection interval, which is a second integer multiplication of the minimum interval. When a new wireless connection is added or an existing wireless connection is removed, the link positions corresponding to wireless connections are adjusted to provide balanced distribution of time slot resource for the wireless connections.

摘要： A device for supporting wireless communication is provided. The device includes a transceiver, an antenna, and a radio frequency (RF) front end system communicatively coupled to the transceiver and the antenna. The RF front end system may include: a RF sampling block coupled to the transceiver and configured to sample signals received from the transceiver and output voltage signals; a RF switching logic coupled to the RF sampling block to receive the voltage signals and configured to switch the front end RF system between a transmitting mode and a receiving mode; a RF transmission gain block coupled to the RF switching logic and configured to increase a transmission power of the signals received from the transceiver; and a RF receiving gain block coupled to the RF switching logic and configured to remove noise signals contained in radio frequency signals received from the antenna.

摘要： A device for supporting wireless communication is provided. The device includes a first Bluetooth transceiver for communicating with a Bluetooth device, a second Bluetooth transceiver for communicating with a client device, one or more processors, and a memory for storing instructions executable by the one or more processors. The one or more processors may be configured to establish, via the first Bluetooth transceiver, a first communication connection with the Bluetooth device, and transmit, via the second Bluetooth transceiver, a Bluetooth broadcast signal indicating an availability of the Bluetooth device, and establish, via the second Bluetooth transceiver, a second communication connection with the client device. The one or more processors may be further configured to receive, data directing to the Bluetooth device, from the client device via the second communication connection, and forward, the data directing to the Bluetooth device, to the Bluetooth device via the first communication connection.

摘要： A wireless roaming method and related system are provided. The method is applicable to an access control device and includes: determining a moving direction of a mobile device that is in a first connection connecting with a first access point; establishing, by a second access point and in response to a determination that the moving direction meets a preset condition, a second connection connecting the mobile device with the second access point, and disconnecting, by the first access point, the first connection. The first access point and the second access point are both connected to the access control device, and have a same static address or a same Identity Resolving Key. This method allows the mobile device to securely and seamlessly roam within the coverage areas of different access points.
