Caltta Showcases Cutting-Edge Emergency Communications Solutions at the 23rd China-ASEAN Expo

The 23rd China-ASEAN Trade & Investment Expo opened from 17-21 September 2026 in Nanning, Guangxi, China.

Under the theme “Intelligent Convergence, Resilient Connectivity”, Caltta Technologies  participates in this exhibition. 

Caltta Technologies is attracting attention with its cutting-edge emergency communication products portfolio. Highlighted innovations include broadband ad-hoc system, narrowband ad-hoc system and portable emergency command case. By leveraging technological prowess to meet changing user demands, these offerings have made Caltta a magnet for partners, customers, and industry experts at the Expo.

• 1. Air-Space-Ground Coordination for Communications in Extreme Scenarios

To meet the demands of extreme disasters, large-scale security operations and sudden incidents, Caltta has built an air-space-ground integrated emergency communication solution. On the ground, DMR and LTE private network base stations, together with communication vehicles, form the on-site communication backbone, extending voice and data to the front line. In the air, UAVs carry video and voice ad hoc networking devices to overcome complex terrain constraints and expand on-site communication coverage. 

Caltta's ad hoc network system delivered key support during severe flood control and disaster relief efforts in Guangxi, China this year, proving its reliability in real-world extreme conditions. 

• 2. Converged Communication: Breaking Communication Silos for Coordinated Dispatch

Built on standard-compliant protocols, Caltta's Integrated Communications system enables interconnection and unified dispatch across isolated systems-DMR narrowband trunking, LTE broadband trunking, PoC, video surveillance, video conferencing and wired telephony-breaking down the barriers between different communication networks. 

Caltta's multi-mode radio enables seamless automatic handover between public and private networks for users, keeping them always connected to guarantee personal safety.

• 3. Intelligent Convergence, Resilient Connectivity

Caltta focuses on developing multi-standard network convergence solutions to enable rapid response and seamless coordination during crises, and continues to expand its footprint in the critical communications market, advancing diverse technology integration and cross-industry collaboration. 

Together with partners and customers, we strive to build a new flexible, intelligent and reliable emergency communications ecosystem for a safer world and better lives.
