As challenges are getting increasingly complicated, it is an indispensable trend to introduce broadband technologies to meet the requirements of professional users from the public safety industry. Caltta 2+4 solution based on broadband technology has been trusted and adopted by public safety users for decades. It integrates voice services, big data, video services, mobile officing, and other application systems to realize flexible industrial applications, which provide massive convenience for public safety users.
Nowadays, legacy voice services can no longer meet the communications needs of public safety service informatization and intelligentization. Visualized command and dispatch based on high-definition audio and video has become an indispensable requirement of public safety communication solutions.
Caltta "2+4" digital DMR trunking solution complies with the DMR and LTE standards and follows the design principles of safe and reliable network architecture, open interfaces, and smooth evolution. In addition to the basic voice and data services, the "2+4" solution provides converged applications, such as visualized dispatch and command, multimedia trunking communications, high-definition mobile video streaming, and mobile officing. It migrates the information collection and distribution mode to mobile communication and collaboration, and upgrades the dispatch systems from the isolated one to the unified one, thus substantially improving the work efficiency of public safety users.
Coordinated dispatching and unified command, DMR/ LTE Trunking hybrid grouping, and hybrid calls via the DMR and LTE convergent network.
The DMR system provides seamless coverage in urban areas to ensure the communication services and emergency handling. The LTE system fully supports Mobile Policing, Video Streaming, and Visualized Command in important places and key passes.
The LTE provides a data rate of up to 100Mbps in the downlink and 50Mbps in the uplink. The signaling delay is shorter than 100ms, which ensures fast issuing of commands. The LTE is a perfect solution to the problem of last-mile broadband data access.
End-to-end encryption and easy access to policing information system. The "2+4" system has been deployed and proven, satisfying the requirements of interoperability with other systems.
Based on SDR platform, the system is analog and digital compatible, and can smoothly evolve towards LTE, hence protecting the customer's investment.
The system supports multi-carrier modulation; a single unit can support up to 4 RF carriers. The intermediate digital frequency combined with an external RF unit doubles system coverage. Industry-leading DPD and Doherty technologies improve amplifier efficiency and decrease power consumption by 80%.
Two-way radios enable users to communicate directly radio-to-radio bypassing the main network. Direct mode is normal operating procedure on the spot, but it is also very useful in tall buildings, tunnels, underground areas, and when operating beyond main network coverage in more remote areas.
The conventional system is an upgrade from the basic radio to radio communications. The radio communicates through high power repeaters with better coverage and faster response times.
Two-way radios enable users to communicate directly radio-to-radio bypassing the main network. Direct mode is normal operating procedure on the spot, but it is also very useful in all buildings, tunnels, underground areas and when operating beyond main network coverage in more remote areas.
Commercial scenarios could involve shopping malls, commercial zones, restaurants, hotels, resorts, theatres, and even sporting events, in which efficient communication and high-quality service for guests are the basic demand. Caltta commercial solution can secure business operations, improve operational efficiency as well as provide high-quality communications at low costs. Caltta's business-critical radios fully meet this requirement and are adored by countless customers globally.
Rail transit is a major livelihood project related to the life of urban residents and the development of the city. Caltta wireless LTE trunking communication solution integrates passenger information system (PIS), onboard CCTV, train control (CBTC), and multimedia trunking services in one system, serving as the key communication platform for data transmission and vehicle management.
With the rapid development of urbanization, city managers urgently need a set of management and coordination systems with real-time information to realize the smart administration of the city. Caltta municipal private network solution is widely used in mobile video transmission, city management, and emergency command. Caltta is committed to providing customized services and professional applications for governmental affairs and smart city construction.
The traditional wireless communication solution can hardly meet the needs of growing service needs at airports and ports. How to efficiently and reasonably dispatch various resources are the main concern during the deployment of the wireless communication system. Caltta provides diversified solutions for airports and ports by utilizing 2G, 4G, PoC, 5G and integrated networks, to improve daily operation efficiency and emergency response. With rich services such as PTT calls, video transmission, location, and work order management, our solution can substantially improve work efficiency and management quality.
When major disasters or emergencies happen, it is necessary to carry out the search and rescue task efficiently with an integrated communication system to provide all-day, all-weather and high-precision communications. Caltta, as experienced in the emergency communication industry, provides an integrated emergency communication solution that integrates the whole forces and processes for an on-site joint operation to realize unified command, quick response, horizontal and vertical connectivity, and data sharing.
Power grid scenarios consist of power generation, power transmission, power transformation, power distribution, power consumption and so on. Wireless communication needs such as data perception, transmission and processing are indispensable. Caltta smart grid communication solution has the ability of flexible networking and rapid deployment, which has great advantages for the reference of new services and will bring great impetus to the construction of a dedicated network for various scenarios of the power grid industry.
