What would be a disadvantage of configuring a wireless router or access point to operate only in accordance with the 802.11g protocol standard?

Answer 1

What is one disadvantage that 802.11a wireless has compared to 802.11g?

A. Use of the 5GHz band requires much larger antennas.

(Has to be this answer, others are just wrong.)

B. The OFDM modulation technique results in a slower data rate.

802.11a = OFDM 54 Mbps 802.11g = DSSS 11 Mbps or OFDM 54 Mbps

C. There are fewer non-overlapping channels available to help reduce RF

802.11a = 8 Channels 802.11g = 3 Channels

D. The use of higher frequencies means that signals are more likely to be obstructed.

802.11a = 5 GHz 802.11g = 2.4 GHz

Other way around, the 2.4 GHz frequency band is crowded, and subject to

interference from other networking technologies such as microwave ovens,

2.4GHz cordless phones (a huge market), and bluetooth. Also the higher

the frequency the better it is at penetrating walls and scattering or

reflecting of walls and ceilings.

Answer 2

The 802.11g protocol is very limited in regards to bandwidth and range when compared to the n protocol. Additionally, 802.11g operates only in the 2.4 GHz range and has a shorter range than any other standard.

Answer 3

The disadvantage of configuring a wireless router to only operate with an 802.11g protocol is that it is likely to ignore older protocols like the 802.11a and he 802.11b protocols. In many cases, even if there is network connectivity, the users will experience slow speeds.

Answer 4

The 802.11g has a better line speed than the 802.11b. (802.11g is up to 54 Mbps. & 802.11b is up to 11 Mbps.)

Answer 5

It wouldn't be compatible with older computers' wireless adapters that can only do 802.11a/b/g. Nearly all wireless access points are backwards compatible with the older 802.11 standards.
