  Cisco High-Density Experience (HDX), a 

feature set that alleviates the negative 
impact on throughput/end-user experience 
when there is an introduction of more 
clients, bandwidth-intensive applications 
and high-density concentrations of clients. 
HDX features include CleanAir 80Mhz for 
interference mitigation, ClientLink 3.0 for 
improved rate vs. range, Smart Roam for 
intelligent roaming handoff and Turbo 
Performance for high client scalability 

The Aruba AP-225 access point has a 
software-configurable dual radio with a 
maximum data rate of 450 Mbps in the 2.4GHz 
band and 1.3 Gbps in the 5GHz band. Also, 
each omni-directional down-tilt antenna in the 
3x3 MIMO design supports three spatial 
streams. The Aruba AP-225 is designed to 
connect with a dedicated mobility controller. 
The APs operated in 802.11ac mode in three 
of the tests. One test validated the throughput 
in an environment where the number of client 
devices increased. 
As shown in 

 on 

, the AP3702i 

provided more than 83.2% greater throughput 
per client than Aruba AP-225 with 60 devices 
supporting 2 or 3 spatial streams. 

Three sets of tests were conducted to 
determine the impact on throughput when 
increasing the distance and/or physical 
obstructions between the access point and the 
clients. During testing, the access points 
operated in the 802.11ac radio band, 5 GHz. 

Throughput values for three types of 802.11ac-
capable client devices were recorded. Six 
different distance and/or obstruction scenarios 
were used. The distance between the access 
point and the client device ranged from 10 feet 
to 150 feet. See 

How We Did It 

on 

 for 

specific details on the variations deployed. 

There were two variations for each of the six 
client locations. In the first four scenarios, the 
client was located in a cubicle office 
environment. In the 100 and 150 feet 
scenarios, the access point and the client were 
in different rooms. 

The maximum theoretical throughput possible 
for each device in each test varied based on 
the type of 802.11 functionality and/or radio 
band being utilized. 

Each client device was tested in each set one at a 
time. Also, each device had different spatial stream 
(SS) capacity. 

 a Dell Latitude E6430 laptop, 3SS 
 a MacBook Air notebook, 2SS 
 a Samsung Galaxy S4 smartphone, 1SS 

As expected, throughput declined as the distance 
or physical obstructions increased between the 
access point and each client device. 

The throughput values are an average of six runs, 
three runs at the two variations for each location. 

The maximum theoretical data rate that could be 
achieved by spatial stream is as follows: 

3SS = 1,300 Mbps 
2SS = 867 Mbps 
1SS = 433 Mbps 

Results for each client at each location are shown 
in separate charts, 

 on the next page. 

The AP3702i exhibited an advantage over the 
Aruba AP-225 in average throughput in all 18 
scenarios of three client devices tested individually 
at six different locations. 

The Aironet 3702i continued to provide robust 
throughput as difference increased between it and 
the client device. The two greatest differences in 
throughput were recorded with the 1SS Samsung 
Galaxy smartphone, 51.9% at 150 feet LOS and 
45.5% at 100 feet LOS. 

The two smallest differences in throughput were 
observed using the 2SS MacBook Air notebook, 
5.5% at both 25 feet Non-LOS and 100 feet LOS. 

The difference in percentage from low to high for 
each client device was as follows: 

 3SS Dell Latitude E6430 laptop: low of 10.3% 

for both 50 feet Non-LOS and 100 feet LOS, 
high of 29.6% for 25 feet Non-LOS 

 2SS MacBook Air notebook: low of 5.5% for 

both 25 feet Non-LOS and 100 feet LOS, high 
of 10.8% for 75 feet Non-LOS 

 1SS Samsung Galaxy S4 smartphone: low of 

12.5% for 50 feet Non-LOS, high of 51.9% for 
150 feet LOS. 

The Aironet 3702i and the Aruba AP-225 are 
designed to provide gigabit Wi-Fi performance to 
802.11ac-capable mobile devices deployed in
