What capability was added to residential gateways to connect to IEEE 802.11b-, 802.11g-, 802.11n-, and 802.11ac-compliant devices?

• A. Bluetooth only
• B. Ethernet-only
• C. No wireless support
• D. Wireless capability

Answer: (D)

A gateway must provide wireless connectivity to work with Wi‑Fi devices across multiple 802.11 standards. To connect devices that use 802.11b, g, n, or ac, the gateway needs a wireless radio and the proper access point functionality, so it can broadcast a wireless network and handle wireless clients. Without wireless capability, only wired Ethernet devices could connect; Bluetooth would only cover Bluetooth devices and not Wi‑Fi devices; no wireless support would make wireless devices impossible. So adding wireless capability lets the gateway serve as a Wi‑Fi access point compatible with all those standards.
