Mobile Client Performance & Compatibility
| Server Version | App version | Encryption | Max Delay | Jitter | Packet loss |
|---|---|---|---|---|---|
| 6.0 and newer | Android ; iOS | TLS (AES-128) | 400 ms | 50 ms | 2% |
| Unencrypted | 2900 ms | 50 ms | 2% | ||
| 5.7+ | 3.3.135 (APK) | — | 2900 ms | 50 ms | 2% |
| 5.3.5–5.7 | 3.3.135 (APK) | — | 800 ms | 100 ms | 3% |
| 5.2 and older | 1.3.0 (APK) | — | 200 ms | 100 ms | 2% |
- Max Number active Mobile Clients per Server: 10000 Units
- Max Active talkgroups per Server: 500 Groups
- Advised maximum number of Mobile clients per Group Subscription: 100
While unencrypted connection allows up to 2900ms of Delay, enabling TLS (AES-128) imposes a limitation on the quality of networks, allowed maximum Delay is up to 400ms.
