Frequently Asked Questions

Why should I consider satellite PTT instead of mobile or radio networks?

Satellite Push-to-Talk (PTT) offers secure, instant voice communication in locations where mobile or radio networks are unavailable or unreliable.
Telespazio Germany provides Iridium Push-to-Talk solutions tailored to critical operations and remote teams across the DACH region.
Satellite PTT ensures KRITIS (critical infrastructure) operators stay connected during network outages, natural disasters, or field deployments in off-grid areas.
It also supports secure communication for enterprises operating in high-risk, regulated, or geographically isolated environments, making mobile satellite communication possible in the most remote areas.

Who typically uses satellite PTT solutions?

Satellite PTT is widely used by KRITIS (critical infrastructure) sectors such as energy, water, and transportation, as well as emergency response teams, maritime and aviation operators, government, and defence.
These organisations rely on satellite PTT to maintain voice coordination in mission-critical, remote, or mobile scenarios where terrestrial infrastructure is insufficient.
Telespazio Germany provides Iridium satellite phone deployments with regulatory alignment and operational reliability for KRITIS applications across Germany and the EU.

What advantages does satellite PTT offer over traditional walkie-talkies or mobile apps?

Satellite PTT enables instant, encrypted group communication across vast distances without reliance on cellular towers or line-of-sight.
Unlike walkie-talkies, it delivers global coverage and clear voice quality for KRITIS operators and mobile field teams.
Compared to mobile apps, satellite PTT eliminates dependence on public networks—ideal for business continuity and operational security.
Telespazio Germany integrates Iridium phone solutions into compliant, secure infrastructures for regulated and remote deployments.

What makes Iridium different from other satellite systems?

Iridium operates a Low Earth Orbit (LEO) satellite constellation with global coverage, including polar regions and remote maritime zones.
This ensures low-latency, always-on voice communication in regions where KRITIS operators and emergency services often work.
Telespazio Germany partners with Iridium to support critical voice services across regulated and geographically complex industries.

How fast is communication using satellite PTT?

Iridium Push-to-Talk delivers near real-time voice exchange—typically with sub-second latency across continents.
This speed is vital for KRITIS operators, emergency responders, and infrastructure teams that rely on rapid, coordinated decision-making.
Telespazio Germany ensures consistent performance by integrating integrating satellite communication service and Iridium satellite PTT into high-availability KRITIS communication networks.

Is satellite PTT communication secure?

Yes. Iridium PTT uses end-to-end encryption and international security protocols to protect voice communications.
Telespazio Germany integrates Iridium PTT into secure IT frameworks designed for KRITIS (critical infrastructure) and enterprise users.
Telespazio ensures compliance through secure architecture, firewall controls, and protected access tailored to regulated industries in Germany and the EU.

Why should I buy Iridium PTT solutions through Telespazio?

As an Iridium Tier 1 Partner, Telespazio Germany offers more than just equipment—we manage the full deployment lifecycle.
Our value-added services include technical assessment, installation, configuration, training, and long-term support.
Telespazio Germany specialises in KRITIS-ready PTT solutions that meet the operational, regulatory, and security needs of critical infrastructure sectors.
