“Apple has been playing it cool on the WiFi side of things lately,” Brian Klug reports for AnandTech. “It started with the previous Airport Extreme (Gen 4) which quietly introduced three spatial stream support, followed up by the Early 2011 MacBook Pro update which brought a three spatial stream compliant WLAN stack, and now has continued with an even more understated update for the Time Capsule (4th generation) and Airport Extreme (5th generation).”
“Both updates launched just prior to this latest round of Apple launches, which included the Mac Mini, Macbook Air, and Thunderbolt Display, but unlike those three, the Time Capsule and Airport Extreme updates saw almost no mention,” Klug reports. “Starting with the exterior packaging, you’d be hard pressed to tell that a particular Time Capsule or Airport Extreme is the newer refresh.”
Klug reports, “What’s changed between both previous generations is simple — the Time Capsule gets an official 3TB option, and both the Time Capsule and Airport Extreme now have a much more powerful, modern, and better-performing BCM4331 based WiFi stack… I wager the vast majority of Airport Extreme and Time Capsule owners have no idea what 3×3:3 is or how to even check their physical link rate, and for the most part that’s a testament to how stable these devices are. Maybe that’s the reason why Apple doesn’t make a super huge note about changes like markedly improving their WLAN connectivity. One thing is for certain, Apple’s wireless division is either playing it incredibly cool, or honestly not getting the credit it deserves.”
