A USB client dongle for a permitting kiosk has a small external stub antenna, while staff phones have no visible antenna. What client-antenna fact should the technician recall?
Select an answer to reveal the explanation.
Short Explanation
Phones hide their antennas; some USB sticks wear a tiny stub on their sleeve. Both can be perfectly normal 802.11 clients. Visible metal is not a band death sentence or a MIMO killer by default.
Full Explanation
Most phones and many laptops use internal client antennas, while some USB or PCIe adapters provide external or detachable antennas. Presence or absence of a visible antenna does not by itself determine whether 802.11 is supported, which bands are available, or whether MIMO is possible. Technicians should expect mixed client antenna form factors in municipal fleets. Install and support work focuses on drivers, profiles, and RF conditions rather than assuming external antennas are required for every client.
