1. What is the communication range of UZ2400?
   
   UBEC provide three various modules in communication range for various applications. U-force module for the application >100m, U-power500 for the application of >500m, and U-power1000 for the application of >1000m. Please refer to the product brief : “BF-2400-02”.

2. What is the interference characteristic of UZ2400 in 802.11n environment?
   
   Because the modulation of 802.11n is as the same as 802.11g, the interference characteristics of UZ2400 in 802.11n environment are similar to that in  802.11g. For in-band interference, the interference rejection is 0dB. For out-of-band interference, the interference rejection is above 40 dB. Please refer to “AN-2400-04”

5. Can UZ2400’s FIFO support SPI continued mode?
   
   While battery life is ultimately a function of battery capacity and application usage, the ZigBee protocol was designed from the ground up to support very long life battery applications. Users can expect a multi-year battery life when using standard batteries in a typical monitoring application.
