ITPEC FE Morning October 2019 Question 33
ITPEC FE Morning October 2019 — Question 33 of 80
IEEE 802.11n Max Data Rate — recall the maximum theoretical throughput of Wi-Fi standards.
Key Wi-Fi standards and their max data rates:
- •802.11b →
11 Mbps - •802.11a / 802.11g →
54 Mbps - •802.11n →
600 Mbps - •802.11ac →
6.9 Gbps
Why not others:
- (a) 11 — this is the max rate for 802.11b
- (b) 54 — this is the max rate for 802.11a/g
- (c) 248 — does not correspond to any standard Wi-Fi specification
Key rule: 802.11n achieves 600 Mbps using MIMO (Multiple Input Multiple Output) and channel bonding (40 MHz channels).
