WLS-R01 is a 2.4GHz wireless receiver, it is mainly installed in fixed position to receive the 2.4GHz wireless Locating data of WLS-T01 broadcast. In the other hand, WLS-R01 is also a wireless converter (called Router) from 2.4GHz to 400MHz. it can effectively use 400MHz high transmittance characteristics to extend the wireless transmission distance, and don't need add wire between the communication paths. The WLS software in the PC can use transparent function of RFU-400 to poll the wireless Locating data of WLS-T01, and then calculate the relative position of WLS-T01 by the algorithm. WLS-R01 include two wireless frequency, one is ISM 2.4GHz global common frequency band total have 16 channels, the range of 16 channels are 2.405GHz to 2.48GHz, it can separated into 5MHz segments, and the wireless transmission range (line of sight, LOS) is 100 meters; the other is 400MHz frequency band total have 16 channels, the range of 16 channels are 429.1750MHz to 429.2375MHz and 429.8125 MHz to 429.9250 MHz, and the wireless transmission range (line of sight, LOS) is 500 meters. In addition, the user can divide four groups ID in the each 400MHz channel to avoid adjacent channels affect each other. The user can simply use the DIP switch and rotation switch to configure the parameter, and don't need to add wire between the communication paths, that can speed up to build the system, and reduce the cost, so it very suitable for use in item tracking, personnel movements, factory regional management and other applications.
