Sentinel PTT vs. Traditional Radio
Why modern organizations are ditching expensive tower infrastructure for carrier-integrated push-to-talk.
| Feature |  | Traditional LMR |
|---|---|---|
| Coverage Area | Nationwide (LTE/5G + Wi-Fi) | Limited to Tower Range (Local) |
| Infrastructure Cost | $0 (Uses existing networks) | $10k - $500k+ (Repeaters & Towers) |
| Setup Time | Instant / 24-48 Hours | Months (Construction & Licensing) |
| Audio Quality | HD Digital (Crystal Clear) | Analog (Static & Interference) |
| GPS Tracking | Real-time (Built-in) | Expensive Add-on / Not Available |
| FCC Licensing | Not Required | Required & Complex |
| Interoperability | App, Radio, & Dispatch | Hardware Only |
| Redundancy | Multi-Carrier (AT&T + T-Mobile + Verizon) | Single Point of Failure (Tower) |
The Critical Differences
No Towers Required
Traditional systems require expensive repeaters and FCC licensing. Sentinel uses existing nationwide LTE/5G networks, giving you instant deployment without the capital expenditure.
Unlimited Range
If you can get a cell signal or Wi-Fi, you can talk. Your team in New York can talk to your team in Los Angeles as if they were in the same room.
Advanced Intelligence
Voice is just the beginning. Sentinel includes real-time GPS tracking, emergency alerts, and a browser-based dispatch console that traditional systems simply can't match.
