P2D allows users to have 2-way voice communications, much like old style 2-way Push-to-Talk (PTT) "walkie talkie" radio systems. But unlike radio systems, P2D uses standard network technology and standard terminals, and can even use the existing mobile networks. MobileWorks has combined this technology into its retailer terminals, and into the Maestro handsets.
Use it to replace traditional radios.
Example:
If you are a shopping centre, why implement a radio system when P2D can do so much more? Why not have a single integrated system on a single integrated platform, and take advantage of system integration, and reduced costs, but NO loss of functionality? If you are a international trucking company that has had to provide your drivers with mobiles as a traditional radio system did not provide the coverage required, why not use P2D? It can use existing mobile networks, providing virtual global coverage. Calls are cheaper, quicker to make, more effective. You can even track the device, and see where it is at any point in time.


Multi Function handsets
Example:
If a centre is using Sentinel, then the retailer handset can be provided with P2D capability. If an organisation is using Maestro, then voice communications can be provided via P2D.
Management Control screens
Example:
You want to broadcast a general message. You select the group, and press the speak button, and say what you have to say. However, you can also see that one or two members of the group are not present, so you know they will not have received the information, and can follow up with them later. Sentinel will capture this information and record it.


Multiple Features
Example:
This ability allows the centre to use the device as a traditional 2-way communications device, but also allows the retailer or end user to use the device as a traditional mobile phone. This is a potential non rental revenue generation opportunity.
Networks
Example:
If a centre already has good mobile coverage, then there will be no need to roll out ANY network for the system to work. Indeed, through use of a mobile network, and as long as the centre is willing to enter a contract, then the terminal cost itself may well be subsidised by the network operators.
Reduced call charges
Ease of use
Example:
Just as in traditional radio systems, you press a button, and start talking to the defined end person(s). Unlike a radio system, you are using a standard device that can be used for so much more – such as a Sentinel retailer terminal, or a Maestro terminal.
