Testing was conducted on preproduction 3.06GHz Intel Core 2 Duo–based iMac (Late 2009) systems. Performance will vary based on system configuration, network, file sizes, data sets, wireless interference, and other factors. Performance tests are conducted using specific systems and reflect the approximate performance of Time Capsule. 2. Based on a comparison with Apple’s 802.11g products. Comparison assumes AirPort Extreme network with 802.11n-enabled computer. Accessing the wireless network requires an AirPort- or AirPort Extreme–enabled computer or other Wi-Fi Certified 802.11a/b/g/n-enabled computer. Actual performance will vary based on range, connection rate, site conditions, size of network, and other factors. Range will vary with site conditions.
