RE: Active and Deep Sleep [per My action item]
Title: Message
Hello Eric and all,
In our proposal responding to the 802.11 TGn call for
proposals,
we describe a MIMO system (NIC) with at least two
antennas.
Power-consumption in these devices is probably
dominated
by the RF chain and the ADC. These are multiplied per
active
Rx antenna.
One power-saving scheme we propose is to vary the
receiver
capabilities (i.e. number of enabled receive chains) based
on
recent history at the device.
Just another variability to throw into your melting
pot...
Best Regards,
Adrian P Stephens

Yogesh,
Are we sure sticking to the 802.11 model is a good thing in the
context of .21 where we are defining a service involving several
technologies?
GPRS/UMTS as a matter of fact has a very different aproach to STA
operational mode. CHeck Alan CArlton presentation in Garden

management
Wherever applicable the
standard shall select network scanning opportunities to coincide with
scheduled wake times to minimize the expended power by switching
between the power save and active modes of operations for the
wireless media employed.
Power Save Mode: The state in which
a STA's transceiver is off in order to conserve power used during the
active mode.
Precisely,
Transceiver: OFF
Internal Clocks: INACTIVE
(except one low frequency clock)
Peripherals: OFF
Network Sync:
OFF
Active Mode: The state in which a STA's
transceiver is on in order to perform typical operations needed
for operation within a wireless system.
Precisely,
Transceiver: ON
Internal Clocks:
ACTIVE
Peripherals: ON
Network Sync: ON
