Prepare for the CompTIA A+ Core 1 (220-1201) exam. In this lesson: the 2.4, 5, and 6 GHz bands, channels, regulations and channel widths, the 802.11 standards and Wi-Fi generations up to Wi-Fi 7, Bluetooth, NFC, and RFID. Includes three original practice questions.
Preview the topics
- Brightwave’s access points in neighboring rooms all use the 2.4 GHz band, and they interfere with each other. In North America, which channels should they use?
- Brightwave wants to track portable equipment with small tags that need no battery, read by scanners at the doorways. Which technology fits?
- A new laptop supports Wi-Fi 6E, and the clinic wants it to use the uncrowded 6 GHz band. What must the access point support?
