Connection is the lifeline, download the latest white paper from TCCA to further discover what is going on for Public Protection and Disaster Relief (PPDR) and commercial network operators (MNOs) of provide either full or partial PPDR services.

This Whitepaper show how improved coverage is creating new opportunities for push-to-talk over cellular technology. We predict it is just a matter of time before the first blue light service makes the switch to PTToC and others follow.

TCCA’s SCADA, Smartgrid and IoT Working Group has published a new white paper discussing the use of ‘next generation’ communications networks by utilities.

Nowadays PoC is the most cost-effective choice for users from various industries who require seamless voice communications and data services, and its security is always the 1st priority to concern. This article discusses in depth the security & reliability of eChat, Caltta's PoC system, and shows you a remarkable and unique secure PoC system.

With the rapid development of wireless communications technologies, legacy analog systems are becoming more and more difficult to meet customer needs, and many countries have introduced time window for migration from analog to digital. DMR is the best technology developed by ETSI to replace analog systems. DMR trunking technology not only has the advantages of DMR's wide coverage and low cost, but also integrates the characteristics of large capacity and high confidentiality, becoming one of the main choices for LMR technologies in various countries and regions. Caltta's DMR trunking system is based on the new SDR architecture, supporting smooth evolution to future broadband, making your private network communications more secure, reliable and efficient.

With the rapid pace of development of wireless networks and the massive proliferation of smart mobile devices, broader opportunities for PTT over cellular (PoC) solutions are emerging.
