Smart Walkie Bridge to 2 Way Radio Walkie Talkies

Enabling Smartphone for UHF/VHF Communication

For Security Agencies: Connect your Ops Room to your deployment sites

Under the PLRD Elective Competency Based Checklist (281220) for Command, Control and Communication (C3) -> E.3.2: Wireless Communications, it mentioned ‘SA has an independent 2-way wireless voice communications system (i.e. not dependent on a telephone company’s 3G/4G/5G network) to support communications between the SA’s Ops Room and its deployment sites.

The first component of the E3.2 assessment checklist requires security agencies to have a 2-way wireless voice communications system that can transmit and receive voice communications from the Ops Room to the ground vice versa and in real-time.

Currently, most security agencies might be using a mobile line to phone call their ground users which actually relies on a telephone company’s 3G/4G/5G network as their sites’ radio talkies are not able to transmit to the Ops Room due to the limited short range. It is unsafe as it might fail the E.3.2 required competency component.

With a Smart Walkie Bridge device, you can now connect your current conventional Two-Way Walkie Talkies to your Ops Room.

Additional benefits of the bridge are: 

  1. Ops Room can monitor multiple sites communication and talk to guards when required.
  2. Recordings are stored for 30 Days for each site and can be used for trainings and incident reports.
  3. Use Smart Walkies to cover blindspots of existing radio walkies and yet still be able to talk to them.
  4. Extend your 2-Way Walkie Talkies range to reach Smart Walkie Talkie users who are far away thereby being able to connect your entire team even when they are in different locations.

Smart Walkie Bridge can interconnect any radio system to the apps or to each other. This includes conventional and trunked analog FM, ETSI DMR, ETSI TETRA, MotoTRBO, APCO P25 FDMA, and NXDN.

How It Works

 1. PTT Call from PoC to 2-way Radio 

When an user make a PTT call from a smartphone to a group, the gateway system works as below: 

• The PoC app on the gateway receives the PTT call from the PoC group. 

• The PoC-COS/COR(ST-RoIP4 only) and iDats DSP of the gateway detect the PTT call. 

• The gateway generates the PTT signal to control the connected 2-way radio to make TX. 

• The gateway forwards the voice message from the PoC group to the connected 2-way radio. 

• The connected 2-way radio transmits the voice message to the 2-way radio channel. 

• After the user release the PTT call from the smartphone, the gateway also releases the PTT control to the connected 2-way radio. 

2. PTT Call from 2-way Radio to PoC 

When an user make a PTT call from a 2-way radio to a channel, the gateway system works as below: 

• The gateway connected 2-way radio receives the PTT call from the 2-way radio channel. 

• The Radio-COS/COR(ST-RoIP4 only) and iDats DSP of the gateway detect the PTT call. 

• The gateway generates the PTT signal to control the PoC app to make TX. 

• The gateway forwards the voice message from the connected 2-way radio to the PoC app. 

• The PoC app transmits the voice message to the PoC group. 

• After the user release the PTT call from the 2-way radio, the gateway also releases the PTT control to the PoC app.
