Uma tecnologia interessante: Zigbee e Wi-Fi juntos....

GreenPeak Technologies has developed a new generation of ZigBee transceivers to make the smart home more reliable, secure and power efficient. ZigBee shares the 2.4 GHz frequency band with other Wi-Fi equipment and the GP501 transceiver has a coexistence interface to allow optimized and co-located ZigBee/Wi-Fi radios to work in the same device, successfully avoiding RF interference when operating simultaneously. This coexistence interface enables arbitration over the shared radio frequency medium to prevent contention, signal degradation and data loss. A new key feature of the GP501 ZigBee transceiver chip is the Deep Packet Inspection for ZigBee applications. Deep Packet Inspection (DPI) enables advanced packet management, allowing the host processor to go into a deep-sleep mode to conserve power. While most other ZigBee transceiver chips only include a superficial inspec...
