Two Way Radio GPS
Know where your team are, all of the time!
GPS (global positioning system) is a mechanism which a device can use a number of in-range satellites to triangulate it's position and transmit that position back to the repeater or base station. This enables the supervisor to more effectively manage team members by knowing their current location.
For more information on GPS, download this Motorola GPS information sheet.
GPS is designed for outdoor tracking. See "Indoor tracking" for indoor solutions.

GPS is a standard feature of the Motorola SL4000e.
Time Division Multiple Access (TDMA)
TDMA is a technology that allows several users to share the same frequency channel by dividing the signal into different time slots. With DMR this is two time slots to every 12.5KHz frequency channel allocation.
Before DMR every 12.5KHz frequency allocation could carry just one broadcast of RF traffic. Now with DMR 12.5KHz bandwidth allows two voice channels.
See the video for an explanation on how this works.

Capacity Plus
Capacity plus is a quasi-trunking solutions that uses DMR TDMA time slot technology to mimic trunking technology. Capacity Plus will automatically select an available time slot for the radio transmission. This allows for potentially unlimited channels or talk groups. The only restriction is the amount of available time slots.
Capacity Plus is only available for re-repeater-based systems, as it's essentially a repeater licence upgrade. Any Capacity Plus compatible radio will work on a Capacity Plus enabled repeater.
Note: Capacity Plus is repeater-based and is not available without a repeater.

Two Way Radio Transmit Interrupt
Transmit interrupt ensures that critical message gets through.
Transmit interrupt allows for a priority message to be sent to all radios within your network. Interrupting all ongoing conversations, this feature is commonly used in emergency situations or as a way to offer new instructions to workers.
When purchasing two way radios you can choose to only have this feature programmed to radios that will be used by senior members of staff. This minimizes the potential for it to be abused by workers, meaning that should it ever need to be used all members of staff will be aware of its importance.

Transmit Interrupt is a standard feature of the Motorola SL4000e.
Lone Worker
Lone Worker is a feature found on many two way radios where it's able to send a pre-determined signal, for example a distress call or alarm, to other radios in range, Lone Worker requires some type of interaction from the radio user after a period of radio inactivity.
An example of this is the radio can be set to require the radio operator to interact with his or her radio once every 30 minutes. If they fail to do so, their radio will start making an audible sound. If there is still no interaction with his or her radio within 1 further minute, a alarm will sound to other team members to tell them a team member is not responding to Lone Worker.
The supervisor can then dispatch another team member to the non-response team member's last known location to offer assistance.

Lone Worker is built-in to the Motorola SL4000e.
Two Way Radio Bluetooth
Wireless two way radio accessories that utilise Bluetooth...
Bluetooth connectivity allows audio accessories to be connected to the radio wirelessly via Bluetooth.
Most manufacturers offer Bluetooth earpieces which are only suitable for their products. This is because they generally only want you to choose their accessories, but also because of the different ways their radios work.
It's important to note that Bluetooth is only available on some models and must be taken at the point of purchase as it cannot be added later.

Bluetooth is built-in to the Motorola SL4000e.
