What is RoIP?
It is a solution to transmit the radio signal Over IP
TCE RoIP System comprises of RoIP Gateway and Management Software.
RoIP Gateway transforms the analog voice to digital data and vice visa.

3. TCE’s RoIP
The RoIP Gateway equips with a technology that converts analog audio signals into a digital data transmitted through the Internet, WAN/LAN.
At the receiving end, the digital encoded data will be decoded and converted back to analog audio and radio control signals.
The analog audio is encoded with a standard audio codec, such as G.711, G,723, etc. The digital encoded data are packed into UDP (User Datagram Protocol) or TCP (Transfer Connection Protocol) or a similar transport layer protocol for transport over the IP Network.

4. Features Of RoIP Gateway
Model: RIPG-0100
. Integrates the radio networks at different locations, with different frequencies into one network.
. Supports live radio voice recording in PC up to 30 sites.
. Works with any standard WAN/LAN networks supporting DHCP network.
. Compatible to all mobile or portable radios with PTT, COR, Audio In & Audio Out.
. Designed for harsh environments and no computer is required at site.

5. Features Of Advanced Model?
Model: RIPG-0200
Remotely control up to 15 Frequency Channels in each mobile/base radio.
With the built in VOX function, it is compatible with any
radio that has PTT, Audio In & Audio Out.
The new built in voice GAIN improves the voice/audio quality.
Broadcast to ALL, (in the connected gateways) by just
One-Click from PC.

6. Features of Integrated Model Model: RIPG-0300
It is a basic repeater interface
It is ROIP gateway with RJ45 connector
It is equipped with radio signal strength comparison.
The packet data rate is 8kpcs

10. RoIP Gateway CDR700 Interface
Single-Site for Two-Way Communication
Deploy A Repeater with
High Transmit Power 40W
All of Radios can receive
For this case, Downlink communication is No Problem
It can not talk back to the repeater
It’s Transmit Power: Only 4 or 5W
But for the portable Radio..

Single-Site for Two-Way Communication
Deploy A Repeater with
High Transmit Power 40W
The satellite receiver will send the signal to the repeater
And link them to main repeater by IP
Deploy the satellite receivers
Then the radio PTT
The solution is…

14. Advantages of RoIP 1. Bridging radio networks over long distance
2. Extend the Communication Range
Individual radio networks will be linked by the gateway
regardless of the distance.
Replace the cumbersome and costly repeater links.
Remote access to the radio networks by PC from
anywhere part of the world.

15. Advantages of RoIP 3, Bridging networks across frequency band
Integrates the radio networks operating with different frequencies.
E.g. : Marine VHF radios to Air-band radios
UHF radios to VHF radios, etc.
Integrates radio networks operating in different protocol.
E.g. : Digital radio to Analog radios
– MOTOTRBO to GP/GM
Integrates radio networks operating in different modes.
E.g. : Conventional system to Trunking system
– GP328 to Iden, etc.

16. Benefits of RoIP Cost Effective : Easy Deployment Expandable interface
affordable hardware
minimum installation work
less maintenance service
Easy Deployment
Expandable interface
E.g. : phone patch
User Friendly Software

17. RoIP Application (1) cross frequency link
Air-band radio network <---> Land UHF/VHF network
Marine VHF <---> HF SSB or on board UHF
Amateur CB Radio/Ham <----> Professional VHF/UHF radio
800Mhz Smartnet/Smartzone System <----> 400Mhz Tetra System

18. RoIP Application (2) Cross System Example:
Conventional System to MPT1327 analog Trunking
Conventional System to Smartnet/Smartzone Trunking
Conventional System to LTR Trunking
Conventional System to Tetra Digital System
Smartnet to Tetra
Analog System to Digital System
Conventional, Analog Trunking and Digital Trunking

20. RoIP Application (4) Remote Channel Selection – Model RoIPG-0200
Even when the base station or repeater is located far away, one can still switch the channel via RoIP from within the control room.
When there are a lot of talk groups on different channels, the operator can switch the channel to the desired channel via RoIP gateway and software (e.g. : port operator, transportation company, hotel management).

RoIP Application (5)
Movable Repeater system (MRS)
By integrating a repeater and a Radio IP Gateway in a vehicle, the MRS is a instant solution for quick deployment requirements. MRS uses the broadband connectivity from the cellular 3G (HSDPA) or VSAT to achieve its mobility. MRS is the best solution for natural disaster rescue, army training, VIP security and other important movable actions.
