Can a UHF Reader Be Connected to UHF Antennas Wirelessly?
And can Bluetooth be used for this purpose?
It really depends on what you mean by "connected." It would be possible to separate an antenna from a reader and power the antenna separately, and to then send commands to the antenna via a Bluetooth or Wi-Fi connection. This is not very practical, though, since you would need to build a lot of additional capabilities into the antenna—it would need to have a separate power source, a Wi-Fi or Bluetooth transceiver, and some kind of central processing unit to understand and execute the commands. What's more, you would be adding a lot of cost to the system without achieving much in terms of benefits.
If you are inquiring if the antenna can be powered via a wireless connection, then the answer is that it cannot. You can provide power over Ethernet, but power over Wi-Fi would cook people in the room.
