<Bluetooth>
The GW620 provides the Bluetooth 2.1 + EDR specification. The Bluetooth module is the optimal solution for
any voice or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI) using a
high-speed UART and PCM. The Bluetooth solution has an integrated radio transceiver that has been
optimized for 2.4GHz Bluetooth wireless systems. It has been designed to provided low-power, low-cost,
robust communications for applications operating in the globally available 2.4GHz unlicensed ISM band. It is
fully compliant with the Bluetooth Radio Specification and meets or exceeds the requirements to provide the
highest communication link quality of service. Figure1.2 shows the Bluetooth system architecture in the
GW620.
