Why is wireless slower than wired?
- Wireless bandwidth is shared among devices. - Wireless signals are more susceptible to interference from magnetic and electrical sources. - Other wireless networks (such as your neighbor's network) can interfere with the signals on your network. - Certain building materials (such as concrete and cinderblock) and metal (such as a refrigerator) can decrease throughput. - Throughput varies depending on the distance between your networking equipment. - Wireless networks usually use specially coded signals to protect their data, whereas wired connections don't protect their signals. This process of coding signals can slightly decrease throughput, although once coded, data travels at usual speeds.
