PART A. Company Profile

■Unication Portable Radio Design Concept Description：
●At present, the transmission methods (Analog, Digital) used in the radio system,
transmission protocol and transmission network have no consistent specifications
which make it impossible to communicate with each other when the united commu-
nication is implemented. It results in a huge problem in managing and commanding.
Therefore, when this new generation radio is designed, it should consider the
interoperability and compatibility of the transmission methods (Analog, Digital),
transmission protocol (Including MDC1200, 5 tone, 2 tone, DTMF, DMR, P25 and so
on...) and different transmission Network (PTSN, Mobile, Internet and Radio).
●Unication New Generation Two-Way Radio Solution：
1. Unication new generation two-way radio integrates the traditional analog system and
modern digital technology in one which applies to the communication requirements of
analog and digital and is able automatically detect, distinguish and convert the messages.
2. Unication Two-Way Radio can automatically detect, distinguish and convert the messages
in different protocol which allows radios to exchange the information in different protocol.
3. Unication Two-Way Radio also supports on different communication platforms and expand
the communication distances.
4. Unication Two-Way Radio can exchange the text message, picture and other information
with Unication Radios or other radios on site.
5. Unication Two-Way Radio has GPS, map marking function and it is conducive to
management, deployment, monitoring and personnel safety protection.

PART B. U Series Portable Radio Design Concept

When in the emergency situation, users can sending the emergency signal by pressing the emergency button
manually. Besides, when man-down alert function is activated, the radio will send out man-down alert call if the
member is down. When the commander receives the emergency signal, he can via the radio on his hand to
activate the monitoring function to listen to the on-site message, talk to the on-site member and ask the on-site
radio to report the position information.
●Emergency Call and Man-down Alert Call Function：
U Series Radio is built in GPS (Global Positioning System) and provides automatically location report function. It
makes users are able to immediately understand the deployment or the situation of the members in the group
and that means users can dispatch the members and provide the support in a best efficient way.
Unication provide a Map Software which supports Unication radios. The software allows the users to download
the map information into the radios and the users can combine it with the GPS function of the radio which
directly display the map information on the radio's screen, mark out the self-location and the location of other
members in the group.
●Digital and Analog Dual Mode. Improve the compatibility with the existing systems.：
U Series Portable Radio supports multiple Protocol, including MDC 1200, 5 tone, 2 tone, DTMF, DMR, P25 … and
so on. U Series Portable Radio also has these function: Support analog and digital two systems coexisted which
means 2 Protocol can be compatible in one frequency channel, automatically distinguish the Protocol which the
radio receives and demodulate it, automatically distinguish whether the system used by the other radio is
digital or analog system and selects the mode to transmission, and is able to work with the two-way digital and
analog systems of the mainstream brands on the market.
Voice-digitalization in analog system allows users to enjoy the communication quality under the digital system.
Combined with AES-256 certificated by Federal Government of the United States, even in the analog system,
users can have the digital-system-level effect of encryption.
●Picture Transmission Function：
Unication U Series Radio is able to transmit the picture via radio wave in either analog mode or digital mode.
Combined with the radio built-in GPS function, users can directly send the picture which is added the GPS
information, voice memo or text message to another radios. When other radios receive the picture, it can be
displayed directly on the radio's screen and users can know the position information, voice memo and text
message of the picture.
●Analog Communication AES-256 Digital Encryption (SDVOA) Function：
●Display the Information of the Map and the Radio Position in the Group：
●GPS Self-Located and Automatically Location Reported to Specific Radios：
Built-in Bluetooth transmission function. Users can combine it with the Bluetooth wireless speaker mic provided
by Unication. This solve the cable problems which always bother you; users can be more nimble in the mission.
Also, combine the Bluetooth with the mobile camera, user can send the picture to the radio via Bluetooth . Next,
user can report the situation very quick through sending the picture to the specific person via radio.
●Bluetooth Application：
This function allows commander to remote monitor the radios in your group. Commander can through
specific OTA orders to activate any radio's microphone in the group and have the remote monitoring.
●Remote Monitoring Function：
Sometimes, when users are in the mission, they need to temporarily expand the mission areas due to some
special circumstances. Users are often limited by the distance of the communication and this causes the delay of
receiving the command which needs to be transferred to the members. Unication provide R&R function which
allows user's radio to be a radio in general situations. However, when a expanded distance of communication is
needed, user can switch the radio to the repeater mode. The radio on the hand can instantly be used as repeater
and the distance of the communication becomes double.
●Repeater Mode R&R ( Radio and Repeater)：
