7.4 Proprietary Radio Form

The CC1404P radio supports a wide range of modulation formats, using a set of hardware accelerators with

combined modem firmware that covers a wide array of standards and proprietary modulation formats.

Feature Support gives a simplified overview of features of the various radio formats available in ROM. Other

radio formats may be available in the form of radio firmware patches or programs through the Software

Development Kit (SDK) and may combine features in a different manner, as well as add other features.

(1)

Carrier Sense can be used to implement HW-controlled listen-before-talk (LBT) and Clear Channel Assessment (CCA) for compliance

with such requirements in regulatory standards.

(2)

Carrier Sense and Preamble Detection can be used to implement sniff modes where the radio is duty-cycled to save power.

(3)

Data rates are only indicative. Data rates outside this range may also be supported. For some specific combinations of settings, a

smaller range might be supported.
