Best Indoor Wireless Access Point for Spatial Multiplexing

D.

Spatial Multiplexing (SM) is a technique that allows multiple data streams to be transmitted simultaneously over a single radio channel by using multiple antennas at both the transmitter and receiver. This technique enhances the throughput and data rate of wireless networks.

To make use of SM, you need to deploy access points that support multiple antennas, such as Multiple-Input Multiple-Output (MIMO) technology. MIMO uses two or more antennas at both the transmitter and receiver to increase the capacity and range of wireless networks.

Now let's look at the given options:

A. AIR-LAP1242AG: This access point supports 802.11a/b/g standards and does not support MIMO technology. Therefore, it cannot make use of SM.

B. AIR-BR1310G: This is an outdoor access point that supports bridging between wired and wireless networks. It does not support MIMO technology and cannot make use of SM.

C. AIR-LAP1131AG: This access point supports 802.11a/b/g standards and has two antennas but does not support MIMO technology. Therefore, it cannot make use of SM.

D. AIR-LAP1252AG: This access point supports 802.11a/b/g/n standards and has three antennas, making it capable of MIMO technology. Therefore, it can make use of SM.

E. AIR-LAP1524AG: This is an outdoor access point designed for mesh networking and does not support MIMO technology. Therefore, it cannot make use of SM.

Therefore, the correct answer is D. AIR-LAP1252AG is the indoor access point that should be deployed to make use of spatial multiplexing.
