The Caltta 2+4 solution is targeted at enabling mission-critical communications in the private wireless and emergency communications fields for industry users.
Caltta’s 2+4 solution allows users to select the scale of network construction, ensuring communications at reasonable capital expenditure (CAPEX) and guaranteeing long-term development. The telecom solution is designed to provide unified network topology and maintenance, reducing manpower and maintenance costs.
Caltta in a statement today said that the 2+4 solution connects 2G and 4G networks, provides voice, messaging, digital trunking, positioning, data collection, information query, image and video transmission, industry application, and other services in a single network through a unified system and hardware platform.
By providing unified user management and trunking dispatching functions, the 2+4 solution allows for flexible configuration and dynamic dispatching between 2G and 4G groups, and allows dispatching agents to connect individuals and groups to respond to dispatching and emergency command needs.
SDR-based base stations have the following advantages over existing systems in the private network market:
The devices are highly integrated for rapid deployment within small floor spaces, which speeds up installation by 30-50 percent.
RadioFrequency (RF) units can be installed outdoors on the tower, reducing feeder loss and increasing coverage one fold.
RF units have a high power amplifier efficiency (> 40 percent), and its natural cooling capabilities can reduce electricity use by 80 percent.
“The 2+4 solution is a bridge to integrate broadband and narrowband networks, and is a true user-oriented technological innovation,” said Sun Mingliang, vice president of Caltta.
