Power Saving Modes
The MacSync Wi-Fi series is engineered for performance and power efficiency. To optimize battery life while maintaining wireless connectivity, MacSync supports two advanced Wi-Fi power-saving features: Power Save Mode (PSM) and Target Wake Time (TWT).
Power Save Mode (PSM)
- Turn ON-OFF PSM mode using toggle button.
How PSM Works in MacSync
- MacSync notifies the Wi-Fi access point that it's entering PSM.
- Incoming data is buffered by the AP while MacSync sleeps.
- The MacSync periodically wakes up to fetch buffered packets.
- Ideal for reducing idle power consumption in applications where real-time data isn't critical.
Best Use Cases
- Periodic monitoring (e.g., temperature, humidity, or equipment status).
- When power consumption is more critical than latency.
Target Wake Time (TWT)
- Turn ON-OFF TWT mode using toggle button.
How TWT Works in MacSync
- MacSync negotiates a wake-up schedule with the AP using TWT.
- Both device and AP agree on specific wake intervals (e.g., every 60s, 5 min, etc.).
- Between those intervals, the Wi-Fi radio stays off, saving maximum power.
- TWT support is optimized for Wi-Fi 6 (802.11ax) access points.
Best Use Cases
- Battery-operated MacSync devices where scheduled reporting is sufficient.
- Ideal for applications with predictable communication patterns, like environmental logging, energy metering, or periodic system updates.
PSM vs TWT -
| Feature | PSM in MacSync | TWT in MacSync |
|---|---|---|
| Power Consumption | Low | Ultra-low |
| Downlink Support | Buffered via AP | Buffered till next wake slot |
| Latency | Medium | Low to Medium |
| AP Compatibility | All APs supported | Wi-Fi 6 recommended |
| Custom Scheduling | Fixed wake periods | Negotiated flexible timing |
| User Control | Toggle Button | Toggle Button |
Developer Notes -
- Use PSM when compatibility with legacy routers and moderate battery saving is sufficient.
- Switch to TWT when using Wi-Fi 6 infrastructure and aiming for maximum battery life.
- Both modes are available as toggle switches in the MacSync configuration panel, allowing easy adaptation per deployment scenario.
