Push-To-Talk over Cellular
PTT over Cellular (PTToC or PoC) means that radio communication (walkie-talkie) is simulated via the smartphone’s data connection using an app. This means that you can communicate with all other users registered in the app. To be heard, you have to press a talk button, known as a push-to-talk button or PTT button, just like on a radio.
This has the advantage that communication does not take place via a conventional voice connection, but exclusively via the mobile data connection or via an existing router in the WLAN.
Your mobile phone thus becomes a communication device with PTT function! All participants can use their mobile phones as walkie-talkies with unlimited range. A typical push-to-talk connection is established almost instantly. A key advantage of the PTT function is that a single person can reach an active conversation group with a single press of a button; users do not have to make multiple phone calls to coordinate with a group.

Wireless-Bluetooth RSM
Wireless Bluetooth handheld microphone speaker
This wireless handheld microphone can be used with your smartphone or tablet via Bluetooth.
It can be used as a hands-free device for normal phone calls or WhatsApp calls. The microphone is then always open and the PTT normally has no function.
However, we also have a reprogrammed special version in our range which, when the PTT is pressed, switches the microphone on as with a radio and switches it off again when released. This prevents unwanted background noise from being transmitted continuously. This is an important feature, especially for telephone or WhatsApp conferences.
Furthermore, the standard version of the RSM can also be used for apps such as Zello, Zebra and Buddycom, among others!
The handheld microphone has a large, powerful speaker and a microphone on the front. On the right-hand side, there is a talk button and an emergency call button, and on the left-hand side, there is a volume control with push buttons.Â
On the back is a large, robust and rotatable clip so that the handset can be positioned optimally on clothing. It is also equipped with a 3.5 mm jack socket for connecting standard headphones, earphones or sound tubes. The handset’s battery is charged via a USB-C socket.
A USB-C cable (without 220V plug adapter) is included in the scope of delivery.

Bluetooth PTT Adapter
Wireless Bluetooth PTT transmit button adapter
Wireless PTT transmit button adapter with clip for our BT radio dongles or other Bluetooth devices such as smartphones. The adapter has a built-in microphone and a 3.5 mm jack socket for connecting conventional headphones or headsets. This means that earphones or our Near special earphones can also be connected. The adapter detects when a headset is connected and automatically switches from the built-in microphone to the headset microphone. This means that our adapter can also be combined with our ear microphone system or induction system, for example.
This provides a modular system that can be used for personal protection as well as for concealed carrying during surveillance operations. Furthermore, it is possible to switch between mobile phone and radio at any time. This comes quite close to being a jack of all trades…
The adapter has buttons for volume control and call acceptance when making calls. In addition, our wireless external PTT buttons can also be used. When used with a smartphone, the PTT button can be used for various PoC apps such as Zello, Taasta, Wave PTX, Airbus Agnetwork, BTTALK, Buddycom, Grouptalk, Tait, Zebra, and many more.
Talk time is up to 10 hours, standby time up to 50 hours. The adapter’s battery is charged via a USB port. A USB cable (without 220V plug adapter) is included in the scope of delivery.

Neckband headsets with PTT button
BoneCom3 PTT wireless Bluetooth headset with bone conduction earpiece
This Bluetooth bone conduction headset is equipped with two bone conduction earpieces. This means that speech is not transmitted directly via airborne sound, but via vibrations through bone conduction. This leaves your ears free to hear other ambient sounds!
The headset is equipped with a PTT talk button that can be used for smartphone apps such as Zello with a talk button function. This simulates a walkie-talkie or classic radio operation on the mobile phone. These applications are also known as PTT over Cellular, abbreviated to PTToC or PoC. Voice communication is not handled via a normal phone call, but via the data plan.
The headset can only be used to a limited extent in noisy environments.
Item no.: HS-510-07
