CEDIA ESPA EST Practice Test

Answer - A - The maximum transmission range of an indoor 802.11b network access point is 150 feet.

Key Takeaway: The range of an indoor access point is limited by the obstructions in the building. In this case, although the outdoor range of 802.11b is 460 feet, the indoor range is merely 150 feet. Most of signal strength is lost either due to interference with other devices or standing waves.
