transmit a first signal to a receiver device, the first signal including a public key associated with the system;
receive a response from the receiver device, the response including an encrypted public key of the receiver device, the public key of the receiver device encrypted with the public key associated with the system; and
transmit a second signal to the receiver device, the second signal inch ding an encrypted unique identifier, the unique identifier associated with the system and used to establish a Bluetooth connection between the system and the receiver device, and the unique identifier encrypted with the public key of the receiver device.

2. The system of claim 1 , wherein the transceiver is an infrared transceiver, and wherein the first signal and the second signals are infrared signals.

3. The system of claim 1 , wherein the transceiver is a directional millimeter wave transceiver, and wherein the first signal and the second signals are millimeter wave signals.

4. The system of claim 1 , wherein the unique identifier is a Bluetooth device identifier of the system.

5. The system of claim 1 , further comprising a user input control that is communicatively coupled to the communication controller when in operation, and configured to receive a user input and trigger the communication controller to transmit the first signal.

6. The system of claim 5 , wherein the user input control comprises a hard button on an exterior portion of the housing.

7. The system of claim 5 , wherein the user input control comprises a slider on an exterior portion of the housing.

8. A method for initiating a communication session from a user device, the method comprising:
transmitting, from the user device, a first signal to a receiver device, the first signal including a public key associated with the user device;
receiving a response from the receiver device, the response being a signal transmitted by the receiver device, the response including an encrypted public key of the receiver device, the public key of the receiver device encrypted with the public key associated with the user device; and
transmitting, from the user device, a second signal to the receiver device, the second signal including an encrypted unique identifier, the unique identifier associated with the user device and used to establish a Bluetooth connection between the user device and the receiver device, and the unique identifier encrypted with the public key of the receiver device.

9. The method of claim 8 , wherein the first signal and the second signals are infrared signals.

10. The method of claim 8 , wherein the first signal and the second signals are millimeter wave signals.

11. The method of claim 8 , further comprising:
receiving a Bluetooth connection request from the receiver device; and
establishing a Bluetooth connection with the receiver device.

12. The method of claim 8 , wherein the unique identifier is a Bluetooth device identifier of the system.

13. At least one non-transitory machine-readable medium including instructions for initiating a communication session from a user device , which when executed by a machine, cause the machine to:
transmit, from the user device, a first signal to a receiver device, the first signal including a public key associated with the user device;
receive a response from the receiver device, the response being a signal transmitted by the receiver device, the response including an encrypted public key of the receiver device, the public key of the receiver device encrypted with the public key associated with the user device; and
transmit, from the user device, a second signal to the receiver device, the second signal including an encrypted unique identifier, the unique identifier associated with the user device and used to establish a Bluetooth connection between the user device and the receiver device, and the unique identifier encrypted with the public key of the receiver device.

14. The at least one non-transitory machine-readable medium claim 13 , wherein the first signal and the second signals are infrared signals.

15. The at least one non-transitory machine-readable medium of claim 13 , wherein the first signal and the second signals are millimeter wave signals.

16. The at least one non-transitory machine-readable medium of claim 13 , further comprising instructions, which when executed by the machine, cause the machine to:
receive a Bluetooth connection request from the receiver device; and
establish a Bluetooth connection with the receiver device.

17. The at least one non-transitory machine-readable medium of claim 13 , wherein the unique identifier is a Bluetooth device identifier of the system.

18. A system for establishing a communication session, the system comprising:
a transceiver disposed in a housing of the system;
a controller coupled to the transceiver, and disposed in the housing;
a communication controller to interface with the controller and cause the transceiver to:
receive, via the transceiver, a first signal from a remote device, the first signal including a public key associated with the remote device;
transmit, via the transceiver, an encrypted public key of the system to the remote device, the encrypted public key of the system encrypted with the public key received from the remote device:
receive, via the transceiver, a second signal from the remote device, the second signal including an encrypted unique identifier, the unique identifier associated with the remote device, the unique identifier encrypted with the public key of the receiver device; and
initiate a Bluetooth connection between the system and the remote device, using the unique identifier of the remote device.

19. The system of claim 18 , wherein the transceiver is an infrared transceiver, and wherein the first signal and the second signals are infrared signals.

20. The system of claim 18 , wherein the transceiver is a directional millimeter wave transceiver, and wherein the first signal and the second signals are millimeter wave signals.

21. The system of claim 18 , wherein to initiate the Bluetooth connection, the communication controller is to interface with a Bluetooth host on the system in order to initiate a connection request with the remove device.

22. The system of claim 21 , wherein the Bluetooth host provides access control to the system.
