Radio over IP

The Wi-Fi Standard 802.11 has grown massively with popularity over the years and coverage is becoming more pronounced. For businesses that operate within a Wi-Fi area, radio over IP is a great solution where traditional point to point radio communications are limited by building structures that attenuate radio propagation.

Radio over IP uses an Internet Protocol to transfer packets of voice around a network, fairly similar to cell phones as the access points/routers act as "masts". Due to the nature of Wi-Fi, RoIP devices require less power to transmit and therefore can be smaller while still having great lasting battery capacity.

The IP100H has some great features:

For expanding and reinforcing coverage integrity throughout the Wi-Fi network, the AP90M access point router will ensure the handset will work in those wireless black-spots. The access point is just like any other router but with one difference, equipped with high gain antennae the Wi-Fi signals will stretch to further places when paired with the longer aerial on the handset.

Once the wireless setup is complete, for the entire system to function the controller unit (IP1000C) is required. The controller unit connects all the access points to a single point where the voice traffic is automatically controlled. Plus, third-party access points can also be used with the controller. The communicator also acts as a bridge where a dispatchers computer can be interconnected. The Radio over IP network is capable of so much more when linked with the multi-connection controller (VE-PG3).

Remote Communicator

For dispatchers, the remote communicator (IP100FS) software package allows users to use a virtual radio to speak with other users as a group or individual calls. As well as having the ability of sending text message. The software package also enables users to see what radio stations are connected to each access point once a map has been setup.

The desktop microphone (SM-25) and desktop PTT microphone adapter (CT-23) is required to talk to RoIP users.


RoIP Gateway

The RoIP gateway is a device that allows many different communications systems to work together. It has two primary functions: firstly, the gateway allows remote RoIP networks to connect together as if it were one. Secondly, the gateway acts as a converter that integrates many different radio and telephony systems.

Bridge Mode

Bridge Mode Connection

The bridge mode simply bridges two radio systems over an IP network in a unicast transmission. (Unicast is the term used to describe communication where a piece of information is sent from one point to another point. In this case there is just one sender, and one receiver.)

Mixing Function

The mixing function mixes conversations from different bridge groups. By using the mixing function, unicast transmission can be relayed to a different radio group.

IDAS To Analogue Connection

The IC-FR5000 repeater series can be connected with the VE-PG3 via Ethernet cable (IP network) using the UC-FR5000 (#02 or #03) network board. The CT-24 digital voice converter is required for use with the VE-PG3.

IP Multicast Connection with SP-VPN1

When used with the optional SR-VPN1 VPN router, three or more radio groups are connected with an IP multicast transmission system in the bridge mode. (Multicast is the term used to describe communication where a piece of information is sent from one or more points to a set of other points).

Cross Band Connection*

Cross band/cross category connection is possible between VHF/UHF land mobile, marine VHF and air band. Optional audio connection cables allow you to connect a transceiver or repeater easily. * Subject to licensing conditions.

Converter Mode

Converter Mode

The VE-PG3 has built-in RoIP and SIP gateway, IP router and IP PBX functions all in one box. The VE-PG3 can interconnect calls between the following connected users. Also the call diversion function redirects an incoming call to a third party user.

Physical Interfaces

System Capabilities

IDAS NXDN connection

An IDAS radio user can dial to telephone numbers and connect to radio users from a PSTN line/IP phone line. IDAS individual calling and group calling can be made from other stations. The CT-24 digital voice converter converts analog audio and G.711ì IP phone codec (via analog audio) to the AMBE+2 codec for the IDAS system.

Analogue radio connection

An analog radio* user can make a call using DTMF code. In the analog radio system, all radio users will be called from other stations. *Limited to radios with DTMF encoder/decoder capability.

Remote communicator software, RC-FS10

The optional RC-FS10 remote communicator software can be used with an analogue radio system as well as the IDAS NXDN system. * For analog radio system communication, the RC-FS10 must be used with the VE-PG3.

External equipment connectors

The VE-PG3 has two external equipment connectors for audio input/output, and other switching. Public address system, siren, red light, and other external equipment can be connected to the VE-PG3. The virtual serial port software allows you to control an external device via RS-232C interface.
