Here are answers to some of the most frequently asked questions. For a fuller look at the concepts involved, see the Common Terms page.
Does digital two-way radio always have longer range than analog?
Not necessarily. The real advantages of digital are clearer audio, better group-call management, and extra features — not simply “more range.” Actual distance still depends on frequency, terrain, antenna setup, and how the coverage is engineered.
Is higher transmit power always better?
Not necessarily. Power is only one factor in communication range. Antenna placement, site elevation, terrain obstructions, and local regulations on maximum power often matter just as much.
Is network PTT just “a chat app with a talk button”?
Not exactly. A solid network PTT system also has to handle group management, floor control (who gets to speak), reconnection after drops, weak-network resilience, recording, and permissions — all far more involved than adding a single button.
Does WebRTC equal network PTT?
No. WebRTC mainly solves how to move audio in real time. Network PTT still needs accounts, groups, floor control, and signaling logic on top of that.
Will network PTT completely replace traditional two-way radio?
Unlikely in the near term. In areas with no cellular coverage — or where local reliability is paramount — conventional radio will continue to be used. In practice the two often work side by side.
Does “license-free” mean you can use it however you want?
No. License-free operation typically still comes with restrictions on frequency, power, antenna type, and equipment certification. Rules vary by country, so don’t assume.
Does open-source automatically mean no patent issues?
No. Open-source licenses govern copyright and usage terms; they don’t automatically grant patent rights. The two need to be evaluated separately.
Why are radios starting to look more like “platforms” than standalone devices?
Because users want more than just voice connectivity — they want accounts, groups, recording, location tracking, and cross-region coordination. All of that lives in software and services.
