Cisco Aironet Series 1700/2700/3700 Access Point Deployment Guide

Cisco Aironet Series 3700 Access Point

Figure 66

Channel Bonding Allows More Usable Bandwidth (Similar to a Multi-Lane Highway)

So, the net take away is that 802.11ac permits faster speeds, allowing clients to take advantage of the additional bandwidth and
complex modulation for over-all performance enhancement while maintaining backward compatibility with 802.11n and
802.11a/g systems already in place.

Figure 67

Faster Speeds with Newer MCS Rates and Bonding – Up to 433 Mbps on 1 Stream.

Faster speed occurs when you use multiple spatial streams. Newer smart phones may likely support only 1 spatial stream, but
higher-end tablets and notebooks will typically support 2 or more spatial streams. Let us look at speeds when using 2 and 3
spatial streams.
