How does the public and Private Integrated walkie talkie realize cooperative work under multi-mode communication?

　　 In some special industries , Such as public security 、 meet an emergency 、 Fire fighting and other industries , In order to meet the business needs of the industry and expand the intercom communication distance , Generally, self built walkie talkie cluster network will be adopted , That is what we call dedicated trunking communication . At present, the more common ones in China are PDT and TETRA And other private network cluster systems . These private network clusters cannot be interconnected , meanwhile , The private network cluster cannot communicate with the public network . Beifeng TP800 Public Private Integrated walkie talkie Public Private Integrated walkie talkie enables all products with different communication modes to work together effectively , Solve the problem of single public network / Limitations of single private network .

　　 Simple interface design ： Convenient and efficient operation

　　BF-TP800 Public Private Integrated walkie talkie Public Private Integrated walkie talkie as a professional and playable product , The overall design is more in line with the younger needs of market users . The whole machine is designed in strict accordance with ergonomics , The rear cover of the fuselage at the side and back are made of non slip texture , One hand grip is not easy to slide , This is especially suitable for railway ports 、 Urban law enforcement 、 Police duty 、 Logistics, transportation and other user work scenarios .

 

　　 Besides , Custom double on the side PTT The key arrangement is simple and orderly , Corresponding to public network and private network respectively , Users can realize different mode conversion with one key in different communication environments . The emergency alarm button on the top , The color is eye-catching and divided independently , In case of emergency , The user can find and operate... At the first time , Personal safety is effectively guaranteed .

　　 The product is equipped with full digital keyboard 1.77 Inch half transparent color screen , The upper and lower screen display of information corresponds to the public network and private network modes respectively , Pair with the side double PTT key , It can receive voice of public network and private network at the same time , In the general setting menu, you can independently set the sending and receiving priority of two kinds of voice . The design of setting menu is simple and logical , Private network / Public network / The whole machine is set separately , It's easy to get started without reading the instructions . Because many frequency data and parameters are operated by computer programming software , This interface design makes it much easier for users to set menus .

　　 Multi communication mode selection ： Achieve smooth application

　　 With cloud computing 、 Big data applications , Wireless private network will break the information island and external connection , Through the fusion of width and narrowness 、 Integration of public and private networks and 5G Advance of , Become an important link in the interconnection of all things .

　　 In such a market context , Beifeng BF-TP800 Public and Private Integrated walkie talkie is based on a deep understanding of industrial applications , Further break the product technical barrier of single public network or single private network , It provides private network and single mode for different users 、 Public network single mode 、 Mixed dual mode of public and private networks 、 Relay mode communication selection of different modes .

　　 In public network mode ： When this mode is turned on , The private network is not turned on . When leaving the factory, users can choose to adapt to Beifeng cloud communication / Zhuo Zhida / Good reason / Bonard any platform . Rely on public operators ( Move / Unicom / telecom ) The Internet , formation 4G/3G/2G The whole network is interconnected in real time, and the public network cluster intercom system covering the whole country .

　　 Private network mode ： When this mode is turned on , The public network mode automatically stops working . Under the normal mode of private network, the preset channels can be managed in different regions , In practice, different purpose channels can be stored in different areas, or analog channels and DMR Digital channel subarea storage , Straight through DMR Digital terminal or analog terminal ; When the intercom range is expanded 、 Where relay equipment is required ,BF-TP800 The public and Private Integrated walkie talkie can be relayed to enter the different frequency transfer mode , One click to realize interworking with multiple terminals .

　　 In mixed mode ：BF-TP800 Public Private Integrated walkie talkie Public Private Integrated walkie talkie works in the public network at the same time 、 Private network mode , The status of the public network and private network currently enabled are displayed through the upper and lower screens , It can receive voice of public network and private network at the same time , vice PTT Key corresponds to public network call , Lord PTT Corresponding private network call .

　　 Let's put it into the actual scene , Suppose there is a convoy to travel now , If there are expressways or indoor mobile communication base stations along the way , Using public network intercom mode can solve the problem of long-distance transmission , Ensure that the voice between the front and rear vehicles and the left behind personnel of the base is clear ; When the motorcade travels to mountainous areas or areas with unstable network signals , You can automatically enter DMR Digital mode , Avoid surrounding radio signal interference and noise , Protect the privacy of the call of the same group members . Besides , Pass Beifeng TP800 The conventional mode of private network is pre programmed , It can also be compared with other brands DMR Intercom intercommunication on the same frequency .

　　 In relay mode ： Beifeng BF-TP800 Public Private Integrated walkie talkie the relay gateway function of Public Private Integrated walkie talkie is a function with practicability and operability , It goes from heaven to earth 、 there is nothing one does not understand . Beifeng BF-TP800 Public Private Integrated walkie talkie walkie talkie can realize private network transfer and public network transfer or mutual transfer , For example, the received private voice can be forwarded within the current packet of the public network , The received public voice can also be forwarded on the current channel of the private network , Play the received voice at the same time , Act as an inexpensive relay station to automatically cover areas without signals , Suitable for basement / mountain area / No signal cell / The signals in the blind area such as the construction site are supplemented to realize the interconnection of two long-distance interphone groups .

 

　　 Besides , because BF-TP800 Public Private Integrated walkie talkie general mode support of Public Private Integrated walkie talkie DMR Digital mode and analog mode , Therefore, it also supports digital and analog walkie talkie groups to pass through Beifeng BF-TP800 To realize digital analog interconnection across networks .

 　　 Beifeng BF-TP800 Public Private Integrated walkie talkie the gateway function of Public Private Integrated walkie talkie can also be used as an extension of conventional walkie talkie network . The user can send TP800 After programming, join the existing conventional walkie talkie network , Then forward the call content to the public network platform , Finally, remote listening can be realized by using terminal equipment 、 Unlimited distance intercom effect .
