TDMA dual slots can greatly increase the communication capacity.
Encryption key can be set via software,which can srambling and descrambling the voice call in encryptioned channels.
Usaully one radio can only have one encryption key.
TD500 can support varieties of calls,it supports indivadual group and all call; it also can kill and revice other radios.
It supports point to point communications,only you and the other can talk with each othe,protecting the privacy.
A certain members can be set as a group to communicate together,which greatly improve the efficiency of the communications among the group.
One radio can talk with all the radios that on the same channel,no matter which group the radio is ,this is very useful for dispatching.
