Features Explained

Two Way Radio GPS

GPS (global positioning system) is a mechanism which a device can use a number of in-range satellites to trangulate 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.

GPS Demonstration Video

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 DP4401 Ex.


DMR 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 below 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 trasmission. 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. With a basic Capacity Plus repeater licence you get 25 radio licences included. Any Capacity Plus compatible radio will work on a Capacity Plus enabled repeater.

Linked Capacity Plus

Linked Capacity Plus is an extension of the Capacity Plus system and allows for up to 15 sites. This enables the user to potentially build a reasobably large multi-site system at relatively low cost.

Linked Capacity Plus Video

 

For more information see our Capacity Plus page.

Capacity Plus & Linked Capacity Plus is repeater-based and is not available without a repeater.


Transmit Interrupt

Transmit interrupt is a feature that enables a high priority transmission to take priority over normal priority transmissions. For example a supervisor might want to make an important announcement to the team or call for an evacuation in the event of a incident.

Transmit Interrupt Information Video

 Transmit Interrupt is a standard feature of the Motorola DP4401 Ex.


MPT1327 Trunking

MPT1327 is an analogue trunking soution that makes use of multiple repeaters and creates "channel pools". How it works is that when a radio needs to make a call (or transmission) the MPT1327 controller allocates a free repeater channel to the radio. When the call ends, th e channel is allocated back to the available channel pool. The MPT1327 solution is now deprecated in favour of more modern digital solutions such as DMR or dPMR Tier II and Tier III.

There are stil a very many MPT1327 solutions still installed and that's why some new radios have the ability to operate on an MPT1327 system. Of course when operating on MPT1327, even a digital radio will have to operate in analogue mode as MPT1327 voice traffic is analogue. Usually MPT1327 functionality is an optional extra by way of having an MPT1327 option board fitted in the radio, or a software activation.

 MPT1327 is an optional extra for the Motorola DP4401 Ex and requires an option board installing. You can choose this option when ordering if you need MPT1327 functionality.


Lone Worker Feature

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-reponsive team member's last known location to offer assistance.

 Lone Worker is built-in to the Motorola DP4401 Ex.


Man-down Feature

Man Down provides remote monitoring of workers by detecting if their radio is upright, or if the radio is on it's side assumes there may be a problem. Radios which support Man Down are fitted with an accelerometer (or similar device) which allows them to detect the orientation of the radio. If somebody slips or falls, they are likely to be on their side, Man Down will automatically detect this, activate and transmit an alert to call for help from a supervisor or other team members. This works is almost the same way as your smart phone which knows if you have it positioned portrait mode or landscape mode. See this video below to see how the a works.

Man Down Demonstration Video

The Accelerometer Science

The science which allows man-down to work is almost the same way as your smart phone which knows if you have it positioned portrait mode or landscape mode. See this video below to see how the a works.

 Man Down is built-in to the Motorola DP4401Ex.

Bluetooth

Bluetooth conectivity allows audio accessories to be connected to the radio wirelessly. Most manufacturers offer Bluetooth earpieces whcih 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.

 Bluetooth is built-in to the Motorola DP4401Ex.

Motorola Warranty Options
