2. Private GSM networks with full feature functionality on GSM mobiles just like any PBX Communication on Wheels” or “Rapid Communication Deployment” switches need specialized connectivity’s as they need to interface seamlessly with a variety of communication channels available at the point of disaster including interconnect with GSM / CDMA communication platforms. Interface for Tetra networks and also Options to connect to E&M networks / Magneto lines for seamless communication with private networks NGOs / Red Cross/ Utility companies / State departments / Fire Dept / Security Agencies. Cost effective & Rapid deployment of GSM services on Mobile Disaster Unit Vehicles and Accident Relief trains (ART). Railway disaster management may need “Quad cable” interface Integrated solution with Voice and high speed Data transmission for connectivity support on IP / V.24 / V 34 for data transmission / interface with SCADA applications and also for transmission of Video / images. Backhaul connectivity: Access agnostic, Completely integrated with legacy connectivity's like E1 / PRI / E&M / Magneto / TWT / UHF / VHF & IP / VoIP. Lightweight & Ruggedized - Can be dropped at the disaster site by a chopper. Ruggedized ( JSSS 55555) to meet field requirement Coral Air - Rapid GSM Private Network

3. Supports Analog extensions, VoIP devices, SIP phones, GSM phones & key phones with equal ease thereby ensuring an environment with best of all the worlds. New Generation Soft switch based switch facilitates duplicated / redundant / distributed processing and networking of the field units with headquarters if required. Supports redundancy on critical backhaul connectivity and control cards Low Power Consumption – Can be Powered by small Gensets/ Solar Panels/ Jeep Battery, etc Seamless interface with any of the communication channels available at the point of disaster depending on the site terrain & functional area of the disaster site. Tetra deployments are fast becoming popular so interface for such networks available. Ideal C.O.W system should have GPS / GPRS interfaces and dispatch system to coordinate movement of various vehicles. Coral Air - Rapid GSM Private Network Cont..
