Question

Which of the following was NOT a benefit of the 802.11a over 802.11b?

A. Much greater bandwidth
B. Higher frequency range, resulting in less interference
C. Lower cost of equipment
D. Easier to contain because the signal cannot penetrate walls

Answer 1

The correct answer is C. Lower cost of equipment. The 802.11a and 802.11b are wireless networking standards with differences in frequency range, bandwidth, interference, and cost. While 802.11a offers much greater bandwidth and less interference, it is not cheaper in terms of equipment cost.

Step-by-step explanation:

The correct answer is C. Lower cost of equipment.

The 802.11a and 802.11b are both wireless networking standards, with the main difference being the frequency range they operate on. While 802.11a operates on a higher frequency range (around 5 GHz), 802.11b operates on a lower frequency range (around 2.4 GHz). This higher frequency range of 802.11a allows for much greater bandwidth (data transfer rate) compared to 802.11b.

Additionally, the higher frequency range of 802.11a also results in less interference from other devices such as microwaves and cordless phones that operate on the same 2.4 GHz frequency range as 802.11b.

However, lower cost of equipment is not a benefit of 802.11a over 802.11b. In fact, 802.11b tends to be more affordable because it is an older standard that has been widely adopted.

Finally, both 802.11a and 802.11b signals can penetrate walls, so they are not easier or harder to contain from that perspective.
