Match each IEEE 802.11 wireless standard on the left with its defining operational frequency and technological capability on the right.

  • IEEE 802.11ax (Wi-Fi 6)Operates natively in both 2.4 GHz and 5 GHz bands, introducing Orthogonal Frequency-Division Multiple Access (OFDMA) and Target Wake Time (TWT).
  • IEEE 802.11ac (Wi-Fi 5 Wave 2)Operates exclusively in the 5 GHz frequency band, introducing Multi-User MIMO (MU-MIMO) for downlink transmissions and 160 MHz channel bonding.
  • IEEE 802.11n (Wi-Fi 4)First standard to introduce Multiple-Input Multiple-Output (MIMO) antenna technology and operates in both 2.4 GHz and 5 GHz bands.
  • IEEE 802.11gOperates strictly in the 2.4 GHz band using OFDM modulation to achieve a maximum theoretical throughput of 54 Mbps.

Cevap

IEEE 802.11ax matches the dual-band OFDMA/TWT description; IEEE 802.11ac Wave 2 matches the 5 GHz downlink MU-MIMO and 160 MHz bonding description; IEEE 802.11n matches the pioneer dual-band MIMO technology description; and IEEE 802.11g matches the 2.4 GHz 54 Mbps OFDM description.
Each IEEE 802.11 standard is accurately paired with its primary frequency spectrum and signature channel access/antenna technologies. 802.11ax utilizes dual-band OFDMA and TWT; 802.11ac Wave 2 utilizes 5 GHz MU-MIMO and 160 MHz channels; 802.11n introduced dual-band MIMO; and 802.11g provided 54 Mbps 2.4 GHz OFDM.

Adım Adım Çözüm

1
Identify operating frequency support for each standard
IEEE 802.11ac is strictly 5 GHz; IEEE 802.11g is strictly 2.4 GHz; IEEE 802.11n and 802.11ax support dual-band operations.
Frequency bands separate single-band specifications (802.11g and 802.11ac) from dual-band specifications (802.11n and 802.11ax).
2
Distinguish single-band standards based on modulation and features
802.11g offers 54 Mbps via OFDM on 2.4 GHz. 802.11ac provides downlink MU-MIMO and 160 MHz channels on 5 GHz.
802.11g is legacy 2.4 GHz OFDM, whereas 802.11ac focuses on high-throughput 5 GHz capabilities.
3
Differentiate dual-band standards based on core PHY enhancements
802.11n introduced baseline MIMO, while 802.11ax introduced OFDMA and Target Wake Time.
OFDMA and TWT are key innovations of Wi-Fi 6 (802.11ax), whereas spatial multiplexing via basic MIMO originated in Wi-Fi 4 (802.11n).
