Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If measured outdoors, the 802.11g wireless standard gives data throughput of up to ____ and a range of up to ____
A
11 Mbps / 140 meters
B
11 Mbps / 120 meters
C
54 Mbps / 250 meters
D
54 Mbps / 140 meters
Explanation: 

Detailed explanation-1: -IEEE 802.11g-2003 or 802.11g is an amendment to the IEEE 802.11 specification that operates in the 2.4 GHz microwave band. The standard has extended throughput to up to 54 Mbit/s using the same 20 MHz bandwidth as 802.11b uses to achieve 11 Mbit/s.

Detailed explanation-2: -802.11a. An extension to the 802.11 standard developed by the IEEE for wireless network technology. 802.11a applies to wireless local area networks and supports a maximum a maximum connect rate of 54 Mbps throughput in the 5GHz band.

Detailed explanation-3: -One way 802.11n achieves superior throughput is through the use of a technology called multiple input multiple output (MIMO). MIMO uses multiple antennas for transmission and reception.
