DMR Solution

With the co-work of Caltta DMR digital mobile radios and the PR900 repeater, Single Site Conventional expands the radio communication distance and further enhances the efficiency of the communications. Compared with analog systems, it supports two-time slots, and the radio is more energy efficient so as to ensure a longer working time. In the situation where users are distributed in a small range, Single Site Conventional solution is highly recommended. Saving construction costs for users, it expands communication distance among radios.

IP Connection solution combines Caltta DMR radios and repeaters with IP connection to realize a wider signal coverage. It helps connect cross-city facilities, providing extended coverage and larger capacity for users with IP networks. The typical IP Connection solution scenarios include smart city construction, port and airport, large factory, etc.

Active Link solution provides wide coverage and stable connection based on back-to-back wireless link. It constructs wireless link with fixed repeaters and guarantees signal coverage where there is no IP connection. Basically Active Link solution is frequently used in deserted and wide areas like mountain and deep forest to construct communications network there.

Enhanced Conventional System solution, exclusively developed by Caltta, features dynamic channel allocation which balances channel loading and avoids traffic congestion of data transmission or single repeater failure. It supports 256 sites over IP links, perfectly meeting the needs of big communication capacity in scenarios like large venues, factories, and commercial centers.

Simulcast solution integrates Caltta products(DMR radios and repeaters) and IP connection to realize the effect of 1+1>2. An intelligent dynamic delay compensation algorithm is adopted to ensure simulcast performance and voice quality. Meanwhile, large coverage is also guaranteed. When you are widely distributed in a large area with limited frequency and worry about communication latency, DMR Simulcast solution can help save you from trouble.

Ad-Hoc Network solution is based on Caltta Ad-Hoc devices which are easy and fast to deploy. When emergencies occur in remote areas with no network infrastructures, or when the network is destroyed by disasters, an Ad-Hoc network plays a core role in rescue work. With both fixed and flexible devices, it helps build wireless links rapidly, providing a communication guarantee immediately for saving lives. As Caltta is experienced in emergency&rescue, Ad-Hoc Network solution has guaranteed communication in countless real cases and been highly recognized by customers.

The protocol-level interconnection to eChat PoC system helps realize a real unified command with high voice quality and low network latency. DMR and eChat (PoC) Integration solution eliminates the barrier between DMR and PoC systems, provides fully unified command and dispatch, and lowers the cost of communication devices. Thus, this solution is particularly suitable for places with mixed networking and widely used in public safety, airport, port, and other industries.

DMR Tier III Trunking provides absolutely standard trunking solution. For users who are demanding in capacity and compatibility, Caltta trunking solution realizes the link among up to 512 sites and can smoothly access to other systems. The DMR Tier III trunking communications technology has been widely adopted across the world in sectors, such as public safety oil & gas, and transportation.
