When conducting a site survey for real-time traffic over wireless, which two design capabilities of smartphones and tablets must be considered? (Choose two.)

Many modern smartphones and tablets support 802.11ac (Wi-Fi 5), so lack of 802.11ac support is not a universal or primary design constraint for these devices.

Smartphones and tablets achieve lower data rates than laptops - not higher - due to their antenna and radio hardware constraints.

Smartphones and tablets typically have fewer antennas (often 1x1 or 2x2 MIMO) compared to laptops which may support 3x3 or higher spatial streams, limiting throughput capacity and link reliability for latency-sensitive real-time applications.

802.11r (Fast BSS Transition) is supported on many contemporary mobile devices and is not a limitation unique to smartphones and tablets relative to laptops.

As a direct consequence of fewer antennas and less capable radio hardware, smartphones and tablets generally achieve lower data rates than laptops, requiring more conservative coverage and capacity planning when supporting real-time traffic like voice or video.
