Zorluk: KolayWireless Network Deployment and Standards

Match each IEEE 802.11 wireless standard with its defining operational frequency and key technical capability.

  • IEEE 802.11bOperates exclusively in the 2.4 GHz spectrum with a maximum theoretical throughput of 11 Mbps using DSSS.
  • IEEE 802.11aOperates exclusively in the 5 GHz spectrum using OFDM with a maximum theoretical throughput of 54 Mbps.
  • IEEE 802.11nIntroduced dual-band support (2.4 GHz and 5 GHz) along with MIMO technology for multi-antenna transmission.
  • IEEE 802.11acOperates exclusively in the 5 GHz spectrum and introduced MU-MIMO and channel bonding up to 160 MHz.

Cevap

IEEE 802.11b matches 2.4 GHz / 11 Mbps DSSS; IEEE 802.11a matches 5 GHz / 54 Mbps OFDM; IEEE 802.11n matches dual-band operation with MIMO; IEEE 802.11ac matches 5 GHz operation with MU-MIMO and 160 MHz channel bonding.
Each standard is accurately matched to its specified frequency band, modulation/stream capabilities, and theoretical speed limits: 802.11b (2.4 GHz, 11 Mbps), 802.11a (5 GHz, 54 Mbps), 802.11n (2.4/5 GHz dual-band with MIMO), and 802.11ac (5 GHz with MU-MIMO and up to 160 MHz channels).

Adım Adım Çözüm

1
Identify legacy single-band standards
IEEE 802.11b is matched with 2.4 GHz / 11 Mbps, while IEEE 802.11a is matched with 5 GHz / 54 Mbps.
802.11b and 802.11a were the original legacy wireless standards established for 2.4 GHz and 5 GHz bands respectively.
2
Identify high-throughput dual-band standard
IEEE 802.11n is paired with dual-band operation and MIMO capability.
802.11n was the first Wi-Fi standard designed to operate in both 2.4 GHz and 5 GHz frequency bands simultaneously while introducing MIMO antenna streams.
3
Identify Very High Throughput 5 GHz standard
IEEE 802.11ac is paired with 5 GHz MU-MIMO and 160 MHz channel bonding.
802.11ac focused exclusively on enhancing 5 GHz performance using wider channels and multi-user MIMO technology.
