    • A method and system for establishing a connection link between a master device and a plurality of slave devices in a communications network having a plurality of frequency channels within a radio frequency band known as the unlicensed ISM band, wherein the connection links between the master device and the slave devices are capable of being carried out in a frequency-hopping fashion. The method comprises the steps of sending a link request to the master device requesting establishment of a non-frequency-hopping connection link between the master device and a slave device; establishing the non-frequency-hopping connection link as requested if the master device is able to select a communication channel for such a connection link; and establishing or maintaining the connection link in the frequency-hopping fashion if the master device is unable to select such a communication channel. In order to establish the non-frequency-hopping connection link, channel conditions including the carrier power of the channel and the interference and noise levels adversely affecting the connection link are measured.
    • 一种用于在具有被称为非许可ISM频带的无线电频带内具有多个频率信道的通信网络中的主设备与多个从设备之间建立连接链路的方法和系统,其中主设备与 从设备能够以跳频方式执行。 该方法包括以下步骤:向主设备发送请求建立主设备与从设备之间的非跳频连接链路的链路请求; 如果主设备能够选择用于这种连接链路的通信信道,则根据请求建立非跳频连接链路; 以及如果主设备不能选择这样的通信信道,则以跳频方式建立或维护连接链路。 为了建立非跳频连接链路,测量包括信道的载波功率和对连接链路有不利影响的干扰和噪声水平的信道状况。

    • A system and method are disclosed for reducing interference in simultaneous wireless LAN (WLAN) and wireless personal area network (PAN) signal handling in mobile wireless terminals having both a WLAN and a PAN interface. The wireless terminal includes a first transceiver operating in the PAN network in a communications band and a first communications protocol transmitting first data units. The wireless terminal also includes a second transceiver operating in the WLAN network in substantially the same communications band and a second communications protocol transmitting second data units. The wireless terminal further includes a controller coupled to the first and second transceivers, assigning a higher transmission priority to the second data units than to the first data units when transmission of the second data units overlaps a first occurring transmission of the first data units, to abort transmission of the first occurring data unit. The controller assigns a higher transmission priority to the aborted first data unit than to the second data units when transmission of the second data units overlaps the retransmission of the aborted first data unit, to transmit the aborted first data unit.
    • 公开了一种用于减少具有WLAN和PAN接口的移动无线终端中的同时无线LAN(WLAN)和无线个域网(PAN)信号处理中的干扰的系统和方法。 无线终端包括在通信频带中的PAN网络中操作的第一收发机和发送第一数据单元的第一通信协议。 无线终端还包括在基本上相同的通信频带中的WLAN网络中操作的第二收发机和发送第二数据单元的第二通信协议。 所述无线终端还包括耦合到所述第一和第二收发器的控制器,当所述第二数据单元的传输与所述第一数据单元的第一次发送的传输重叠时,向所述第二数据单元分配比所述第一数据单元更高的传输优先级, 中止第一次出现的数据单元的传输。 当第二数据单元的传输与被中止的第一数据单元的重传相重叠时,控制器向中止的第一数据单元分配比对第二数据单元更高的发送优先级,以发送中止的第一数据单元。
