TH-388 Gen 2: Satellite Backup for Mission-Critical Communication

2026-05-21

Tesunho,a leader in critical communications solutions, will soon launch the second-generation TH-388 Push-to-Talk over Cellular (PoC) radio, with Starlink B25 built-in.
The original TH-388 has already proven itself as a reliable PoC radio for professional teams. This new version builds on that foundation by integrating Starlink's direct-to-cell satellite network, enabling instant voice communication even where no cellular signal exists.

Why This Matters

Before this upgrade, even the best PoC radios were silent in dead zones. The new TH-388 changes that:

Eliminates dead zones – Reliable communication on remote job sites, backcountry operations, and disaster-stricken areas.

No extra hardware – No satellite phone or external antenna required.

Key Applications

The TH-388 with Starlink B25 is purpose-built for teams operating beyond cell tower range:

Emergency Response & Public Safety: Firefighting, law enforcement, search-and-rescue, and disaster recovery operations beyond cellular coverage.

Field Utilities & Infrastructure: Mining, forestry, and construction crews working in remote sites with no terrestrial network access.

Outdoor Logistics & Transportation: Long-haul fleets, remote delivery routes, and maritime operations where traditional cellular service is unavailable.

Rural & Remote Workforces: Agricultural teams, park rangers, and remote site personnel needing constant voice and location connectivity.

Knowledge Corner: What is TMO Starlink?

TMO Starlink refers to the partnership between T-Mobile (shortened to TMO) and SpaceX's Starlink satellite network. It enables direct-to-cell satellite connectivity, allowing standard devices — including PoC radios like the TH-388 — to communicate via Starlink satellites when no terrestrial cellular signal is available.

Launched: July 23, 2025 (U.S. nationwide)

Coverage: Continental U.S., Hawaii, Puerto Rico, parts of Alaska

Key facts: Band 25 (B25) is the specific PCS spectrum used by T-Mobile for this satellite service. The service is designed to eliminate dead zones, covering hundreds of thousands of square miles where cell towers do not reach.No special satellite dish or bulky external antenna is required; the connection happens automatically.
