Clarifying 1250 802.3af operation

When installing 1250 AP on standard 802.3af PoE, according to the following: http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6973/ps8382/product_data_sheet0900aecd806b7c5c.html  :

operation will be limited to a single transmitter per radio with maximum PHY data rates of 150 Mbps instead of 300 Mbps per radio

Just verifying that this means a "single" spatial stream, per Radio. In other words, the radio requires less power due to lowering the amount of spatial streams on both 2.4 and 5GHz radios. This effectively changes the spec. from a "2x3" to a "1x3" on each radio. 1 transmitter and 3 recievers.

Reducing the number of spatial streams (or "transmitters" as described in that document) reduces both overall power draw as well as throughput capability.

Is that technically accurate?

That is correct. The work around was either the AP having to reduce the transmission like you mentioned or a radio had to be removed.
