Major Technical Specification of PTA#
The major technical specifications of PTA define key aspects that ensure efficient and reliable communication between Wi-Fi and Zigbee protocols. These specifications are summarized in the following table.
| Sr No. | Technical Parameter | Description |
|---|---|---|
| 1 | Frequency Band | Operates in the 2.4 GHz band |
| 2 | Protocols Supported | Wi-Fi, Zigbee |
| 3 | PTA Configuration | PTA Main: SiWG917 SoC PTA Secondary: EFR32MG21 devices in Zigbee mode |
| 4 | Communication Interface | Uses three GPIO connections for handshake signals and SPI for serial communication |
| 5 | Interference Management | Protects Zigbee transmission/reception from Wi-Fi interference. Includes provisions to protect Wi-Fi transmissions from Zigbee interference. Future enhancements will address Wi-Fi reception protection. |
| 6 | PTA | Schedules and prioritize packet transmission to minimize collisions. Ensures fair access to the channel for both Wi-Fi and Zigbee devices. |
| 7 | Integration | Implemented on the SiWG917 SoC, which integrates hardware and software components for efficient resource management and interference mitigation. |
