Hopefully at some point the older design will see a firmware update and bring whatever changes and improvements were made. Interestingly enough, though the Bluetooth controller is the same, the 2011 MacBook Pro includes newer firmware (37 vs 20), and software (2.4.3f1 vs 2.3.8f7). The fourth on the right is for Bluetooth, which remains 3.0 and provided by the same BCM2070 as previous models. Inside the 2011 MacBook Pro is a BCM4331 and three clearly U.FL antenna connectors (on the left) for WiFi, as opposed to two in the previous design. 3x3 MIMO support is starting to become relatively common in the PC notebook space, but this is the first for Apple.
The 2011 MacBook Pro refresh is the first line of Apple products to bring 3x3 radios that can finally enable faster transfer rates and better performance at the edge of WiFi range. Instead, if you really want 40 MHz channels Apple recommends using 5 GHz, which Apple clients and Apple APs both allow to work with 40 MHz channels. Maintaining a good A2DP stereo stream for example requires considerable 2.4 GHz bandwidth. Apple's rationale for disabling 40 MHz channel support on the 2.4 GHz spectrum (for both clients and APs) is that Bluetooth needs lots of bandwidth to hop around on, and already a wide variety of Apple desktop and notebook products come by default with Bluetooth peripherals. The first is that it prevents you from being, well, less than courteous and eating up to over 80% of spectrum on the already crowded 2.4 GHz ISM band with one AP. It's a design choice Apple made a while ago which still exists to this day – for two reasons. Other WiFi AP vendors ship firmware which will automaticaly selects 40 MHz channels on 2.4 GHz spectrum per WiFi Alliance rules, but Apple uniformly uses 20 MHz channels on 2.4 GHz. The Airport Extreme still only allows 20 MHz channels on 2.4 GHz spectrum. The Airport Extreme has had 3 spatial stream support for a long time to little fanfare. My wall-mounted Airport Extreme (Simultaneous Dual-Band II) At the time, there were no Apple products that could actually use 3 spatial streams, and as a result many assumed the feature was completely locked down.

One of the most notable improvements over the previous design was inclusion of a full 3x3 radio-again 3 spatial stream support.
Bluetooth 3.0 was provided by a BCM2070, and the whole solution was simply a BCM954224HMB reference design.Ģ011 MacBook Pro WiFi+BT Module-Courtesy iFixitīack when the new Airport Extreme (Simultaneous Dual-Band II) launched, it included one little-hyped feature. The previous 2010 MacBook Pro included 802.11a/b/g/n support using a BCM4322 which included full 2x2 MIMO support, meaning two spatial streams were supported.
One of the more notable changes in the 2011 MacBook Pro lineup is a completely different WiFi chipset and subsequent RF design.
