Which of these factors has the biggest impact on data transmission speed in a wireless network?
A . The access method used for the network
B . The transmission standard of the equipment used
C . The use of strong encryption for transmissions
D . The transmission wattage rating used on the NIC

Answer: B

Explanation:

The speed of a Wi-Fi wireless network connection depends on several factors. Like most kinds of computer networks, Wi-Fi supports varying levels of performance depending on which technology standards it supports. Each Wi-Fi standard is rated according to its maximum theoretical network bandwidth:

A Wi-Fi network connection operates at the highest possible speed that both devices (endpoints) can support. An 802.11g laptop connected to an 802.11n router, for example, will network at the lower speeds of ‘g’.
