8 - Summary
The test results make clear that not all IEEE 802.11ac Wave 2-compliant Access Points perform
the same. Certainly the Cisco 1852i AP performs in all tested respects as well as, and in all areas
outperform, the popular Aruba AP-325 and Ruckus R710 APs.
The tests were devised to highlight performance differences between 802.11ac Wave 1 and Wave
2 devices, but also identified clear differences in the performance of today’s market-leading
Wave 2 Access Points. The tests uncovered performance differences in several areas:
Ten-to-100-client Throughput.
Tests found that the APs deliver from 325 to 425 Mbps of downlink aggregate TCP throughput
with 10 mixed clients. Aggregate throughput gradually decreases as number of active clients
increases. At 100 clients, aggregate throughputs from 150 to 300 Mbps are achieved, down
about 30 to 40 percent from 10 clients.
No-bandwidth clients.
Tests showed that, for most APs tested, an increasing number of clients are deprived of
bandwidth as client density grows. The number and distribution of clients that get no bandwidth
varies appreciably from AP to AP.
MU-MIMO vs SU-MIMO.
The Wave 2 APs tested perform differently in their ability to exploit the Multi-User MIMO feature
of Wave 2. For transitioning clients from Single-User to Multi-User MIMO, the biggest
throughput gains were delivered by the Cisco 1852i and the Ruckus R710.
10, 20 and 30 MU-MIMO clients.
Tests found that, while aggregate throughput for Single-User MIMO clients varies little for 10, 20
or 30 clients, throughput for Multi-User-MIMO clients drops noticeably as the number of clients
grows from 10 to 30 per AP.
802.11ac Throughput.
The Cisco 1852i AP was able to deliver more than a Gigabit/s of actual throughput under certain
conditions. It is possible to make more effective use of unused transmitters to transmit to
multiple devices at the same time.
Testing confirmed that Wave 2 products can achieve unprecedented WiFi performance. Evolution
of the 802.11 specifications has dramatically improved wireless throughput.
