Detailed Description

The NWP can be active or in LPDS mode and takes care of its own mode transitions. When there is no

network activity, the NWP sleeps most of the time and wakes up only for beacon reception (see

Table 6-3).

Table 6-3. Networking Subsystem Modes

NETWORK PROCESSOR MODE

DESCRIPTION

Network active mode

(processing layer 3, 2, and 1)

Transmitting or receiving IP protocol packets

Network active mode

(processing layer 2 and 1)

Transmitting or receiving MAC management frames; IP processing not required.

Network active listen mode

Special power optimized active mode for receiving beacon frames (no other frames supported)

Network connected Idle

A composite mode that implements 802.11 infrastructure power save operation. The CC3220MODx

and CC3220MODAx NWPs automatically goes into LPDS mode between beacons and then wakes

to active listen mode to receive a beacon and determine if there is pending traffic at the AP. If not,

the NWP returns to LPDS mode and the cycle repeats.

Network LPDS mode

Low-power state between beacons in which the state is retained by the NWP, allowing for a rapid

wake up.

Network disabled

The network is disabled

The operation of the application and network processor ensures that the module remains in the lowest

power mode most of the time to preserve battery life.

The following examples show the use of the power modes in applications:

•

A product that is continuously connected to the network in the 802.11 infrastructure power-save mode

but sends and receives little data spends most of the time in connected idle, which is a composite of

receiving a beacon frame and waiting for the next beacon.

•

A product that is not continuously connected to the network but instead wakes up periodically (for

example, every 10 minutes) to send data, spends most of the time in hibernate mode, jumping briefly

to active mode to transmit data.
