The **Preemptive** function will make FreshTomato inform the Bluetooth device about which Bluetooth channel it's operating on. The Bluetooth device can then mark that channel as "in use" and use alternate channels for its own communications. | The **Preemptive** function will make FreshTomato inform the Bluetooth device about which Bluetooth channel it's operating on.

In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates. In reality, most claims of big increases in transfer rates are likely exaggerated. QAM links are more susceptible to noise. As a result, Turbo QAM is generally only useful in very low-noise/ | In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates.
