It has been reported that Apple’s next-generation MacBooks will support gigabit Wi-Fi connectivity, evidence of which was discovered in a recent OS X developer build. The 802.11ac Wi-Fi standard, also known as “5G Wi-Fi,” is capable of delivering theoretical speeds of up to 1.3Gbps and is considered a major leap forward. An earlier report claimed Apple was teaming up with Broadcom to bring the technology to its 2013 Mac lineup, and now Tonymacx86.com points us to a leaked image of a Broadcom BCM94360CD PCI-E mini custom combo WLAN and Bluetooth card that supports IEEE 802.11ac, the same standard Apple is reportedly looking to incorporate into future computers. The card is similar to those found in current Mac models and is expected to be the one Apple uses in its upcoming computers. Apple is expected to announce new Mac computers at its Worldwide Developers Conference on June 10th in San Francisco. Images of the Broadcom card follow below.
