Final answer:
The maximum theoretical speed of the 802.11n Wi-Fi is 600 Mbps. This is attainable with four spatial streams and a 40 MHz channel width in both 2.4 and 5 GHz bands.
Step-by-step explanation:
The maximum theoretical speed of the 802.11n Wi-Fi standard, when operating in both the 2.4 GHz and 5 GHz frequency bands, is 600 Mbps (megabits per second). This speed is achieved by using four spatial streams with a channel width of 40 MHz. It is worth noting that actual speeds often vary based on range, interference, and the quality of the Wi-Fi equipment.
Wi-Fi operates in the radio-wave portion of the electromagnetic spectrum. Due to the properties of these frequencies, signals can penetrate common building materials, allowing for flexible network setups within buildings. The 802.11n standard was a significant step up from its predecessors due to its increased speed and reliability.
