You are planning for client devices in a WLAN that is to be upgraded to 802.11ac. Which one of the following devices is more likely to have support for 3x3:3 radios and 256 QAM?
Laptops are more likely to support advanced wireless features such as 3x3:3 Multiple Input Multiple Output (MIMO) configurations and 256 Quadrature Amplitude Modulation (QAM), which are integral to achieving the higher data rates offered by 802.11ac. These devices typically have the physical space and power resources to accommodate multiple antennas and the processing capabilities required for such advanced features.
In contrast, devices like handheld scanners, tablets, USB 2.0 adapters, and mobile phones are often limited to 1x1 or 2x2 MIMO configurations due to size, power, and cost constraints, making them less likely to support 3x3:3 MIMO and 256 QAM.
