Hello 
everyone , please take a look as my 2 questions below ( as Andrew 's post in this thread / article above )
In case of scenario as attach figure below–> if there are several (5) of u1 equipped iPhone has been grouped together , 5 of DWM3000EVB has been located around 5 iPhones as figure below
Question number 1.) → 5 of DWM3000EVB simultaneously start interacting / ranging to the red color iPhone number 1 , but only Simultaneous interacting / ranging to only specific single / one red iPhone no.1 , right , however , there are still remain of 4 iPhones ( no. 2 - no.5 ) Need to be interacting / ranging to 5 DWM3000EVB , right ? 
Question number 2. ) → regarding to my Question number 1.) above → there are still remain of 4 iPhones ( no. 2 - no.5 ) Need to be interaction / ranging to 5 DWM3000EVB , how to do ? because right now during DWM3000EVB simultaneously start interacting / ranging to the red color iPhone number 1 , as the same time , the rest of 4 iPhone (no.2 - no.5 ) need to be interacting / ranging to the same 5 of DWM3000EVB which have been interacting / ranging to red color iPhone no.1 simultaneously ,too , so how the same 5 of DWM3000EVB will be able to interacted or ranged to the rest of 4 iPhones ( no.2 - no.5 ) SIMULTANEOUSLY during have been ranging / interacting to red color iPhones no.1 ??
cheer
