How it works
Push to Talk (PTT) is like turning your mobile into a walkie-talkie but with a global world-wide range. Instead of transmitting/receiving radio frequencies, Push to Talk uses either WiFi 3G, GPRS or EDGE data connection on your mobile phone to send and receive calls in encrypted mode using VOIP technology.

Features and Functions

Push To Talk (PTT)
Voice communication at the push of a button. Communicate privately on a one-to-one basis, or have a discussion with the whole team on an instant conference call in clear digital clarity.

Data Usage
Most service providers allow a capped data allowance as a part of your monthly usage but you will have to check with your mobile operator which data package you currently have with them. During the encryption process we have compressed the data needed for voice to only 1kbps, so data is only used when you’re speaking but not for any elapsed time during a conversation. We estimate an average of 20Mb is required per month. Wifi usage is not charged by the Cellular network so its use is normally free.

Push To Talk PC / Mobile Integration
Unlike an RF system, office-based staff can now directly support and manage field staff through their PC, rather than a Push To Talk (PTT) mobile phone.

Range of Mobile Handsets
The Push To Talk System is currently available on a number of Nokia handsets to suit different budget and functionality requirements. New handsets are constantly being added to the list that will support our Push To Talk system. Other makes of GSM handsets will also be added shortly including Google Android, Blackberry and HTC.

GSM Wide Network Coverage

World-wide Coverage
Calls can be made between Push To Talk mobile phones almost anywhere in the world.

Benefits

Reduced costs
No extra handsets required: Staff can use a standard GSM mobile handset as both a phone and a Push To Talk (PTT) walkie-talkie.

Better control
Organisations can provide Push To Talk (PTT) mobile phones to all staff - even temporary staff – safe in the knowledge that the phones cannot be abused to make non work related phone calls. Phones can be configured for data-only use so that Push To Talk will continue to work but users are either unable to, or only make restricted GSM phone calls.


NO call charges
Push To Talk (PTT) System works by sending IP packets over the 3G, GPRS or EDGE Data network rather than setting up a traditional voice phone call. As you are not making a traditional voice call, there are NO charges!

Better productivity
Push To Talk (PTT) System allows groups of workers to keep in constant touch with the team, even if dispersed around the country or around the world. Push To Talk (PTT) phones can be also fitted with earpieces with PTT buttons - this allows calls to be made and received without touching the phone.

As backup to an existing radio network
Many organisations, particularly the emergency services, depend heavily on their radio communication systems to co-ordinate staff. Because Push To Talk (PTT) uses the GSM network, it is ideal as an alternative high availability service in the event of the primary radio network failing.
