    • A radio frequency identification (RFID) reader identifies in which room among several rooms the RFID reader is more likely to be located. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving RF signals generated in corresponding pairs of RFID tags. The RFID tag pairs are attached to corresponding regions of each of the rooms. Each of said RFID tag pair including a first RFID tag and a second RFID tag that are spaced from each other by a distance that is larger or equal to λ/4 and smaller than or equal to λ/2 with respect to a frequency of a responding RF signal originated in the pair of RFID tags. A processor selects a larger RSSI of the RSSI's of the signal pair. The processor determines a corresponding sum of the RSSI's selected from each signal pair associated with each room. The processor evaluates in accordance with determined sums, the location in which said RFID reader is more likely to be located.
    • 射频识别(RFID)读取器识别RFID读取器更可能位于几个房间中的哪个房间。 RFID读取器包括用于发送询问射频(RF)信号的发射机。 它包括用于接收在相应的RFID标签对中生成的RF信号的接收器。 RFID标签对附接到每个房间的相应区域。 所述RFID标签对中的每一个包括第一RFID标签和第二RFID标签,所述第一RFID标签和第二RFID标签相对于所述第一RFID标签和第二RFID标签的频率彼此间隔开大于或等于λ/ 4且小于或等于λ/ 2的距离 响应的RF信号起源于RFID标签对。 处理器选择信号对的RSSI的较大的RSSI。 处理器确定从与每个房间相关联的每个信号对中选择的RSSI的对应和。 处理器根据确定的和,RFID读取器更可能位于的位置进行评估。

    • A radio frequency identification (RFID) reader is contained in a mobile station. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving responding RF signals generated in corresponding pairs of RFID tags. Each responding RF signal contains information identifying a corresponding access point (AP). The RFID tag pairs are attached to corresponding regions of each location of corresponding locations. A processor of the RFID reader selects a responding RF signal based on signal strength and derives the information contained in the selected responding RF signal that identifies a corresponding AP among several access points that is the most appropriate one to associate with in a handoff operation.
    • 射频识别(RFID)读取器包含在移动台中。 RFID读取器包括用于发送询问射频(RF)信号的发射器。 它包括用于接收在相应的RFID标签对中生成的响应的RF信号的接收器。 每个响应的RF信号包含标识对应接入点(AP)的信息。 RFID标签对附接到相应位置的每个位置的对应区域。 RFID读取器的处理器基于信号强度选择响应的RF信号,并且导出包含在所选择的响应RF信号中的信息,其识别在切换操作中最适合的接入点中的相应AP。
