    • 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 plurality of polling response transmission times are allocated for a corresponding plurality of remote devices. The remote devices operate according to a first wireless transmission mode, such as Bluetooth LEE. These allocated polling response transmission times are outside of a time interval designated for communications according to a second wireless transmission mode, such as Bluetooth. Each of the polling response transmission times may be offset from a polling packet transmission time by a corresponding delay interval. In addition, a polling packet to the plurality of remote devices is transmitted, and one or more responses to the polling packet are received. Each of these responses is sent by one of the remote devices during its corresponding polling response transmission time. In addition, communications according to the second wireless transmission mode may be conducted during the designated time interval.
    • 为相应的多个远程设备分配多个轮询响应传输时间。 远程设备根据第一无线传输模式操作,例如蓝牙LEE。 这些分配的轮询响应传输时间在根据诸如蓝牙的第二无线传输模式进行通信的时间间隔之外。 每个轮询响应传输时间可能偏离轮询分组传输时间相应的延迟时间间隔。 此外,发送到多个远程设备的轮询分组,并且接收到对轮询分组的一个或多个响应。 这些响应中的每一个在其相应的轮询响应传输时间期间由远程设备之一发送。 此外,可以在指定的时间间隔内进行根据第二无线传输模式的通信。

    • Systems and methods for a communication system implementing a short range communication link between devices advertising available information and services, and user devices which may initiate a request for further information or services. The communication system provides a low power solution utilizing an optimized combination of a carrier sensing and frequency division multiple access to avoid collisions. The optimization involves the use of a random mean zero value offset appended to the advertising devices' transmission frames. The offset increases the likelihood that a first advertising device will recognize the transmissions of another advertiser's transmissions (i.e., determining that a channel is busy) and avoid unnecessary transmissions that will result in collisions. Upon recognition, the first advertiser may shift its transmission frame accordingly, thereby avoiding transmission collisions between advertisers. The communication system may be implemented in either a StandAlone LowRate system, or in a device with a pre-existing operational Bluetooth implementation.
    • 用于实现广告可用信息和服务的设备之间的短距离通信链路的通信系统的系统和方法,以及可以发起对更多信息或服务的请求的用户设备。 通信系统利用载波感测和频分多址接入的优化组合来提供低功率解决方案,以避免碰撞。 优化包括使用附加到广告设备的传输帧的随机均值零值偏移。 该偏移增加了第一广告设备将识别另一广告商的传输(即,确定频道正忙)的传输的可能性,并避免将导致冲突的不必要的传输。 一旦识别,第一广告商可以相应地改变其传输帧,从而避免广告商之间的传输冲突。 通信系统可以在StandAlone LowRate系统中或在具有预先存在的操作蓝牙实现的设备中实现。
