To specify which AP and which band was being used, I used the settings offered in the UniFi network controller or Instant On portal, and swapped them in and out as needed. I then stepped through the different channel widths and bands, letting the connection stabilize before beginning my tests.

With every foot of free space and every obstruction, a Wi-Fi signal attenuates and gets weaker. 5 GHz signals attenuate faster, and provide around half the range of 2.4 GHz. When deciding on how many access points you need, a good general rule is don’t expect 5 GHz coverage to extend further than 2 walls or 30 feet away. 2.4 GHz signals extend this circle out a bit, but with a few walls in the way, getting low SNR links and slow performance is likely. If there is clear line of sight AP range can extend much further, but every wall imposes a dBm penalty. Wall material and quantity are usually more important than distance in a home or small business network. Next, I ran the same test on the 5 GHz band with 80 MHz channels. Wider channels give you the best speeds, but also require a stronger signal for effective use. At the farthest location, the speed advantage of 5 GHz is mostly eliminated. Those results show how the AP performs when it’s 5 GHz signal is hovering around -80 dBm RSSI and around 10 SNR. From the same location 2.4 GHz connections are stronger and more stable. consumption, extending the battery life of clients. Multiuser, Multiple Input, Multiple Output (MU-MIMO) I expected the 3x3 AP12, 4x4 AP15, and 3x3 AC-Pro to perform better here. Their high end performance was less than I expected, and the AC-Pro actually achieved the worst 80 MHz result of the group. At smaller channel widths, these APs leverage the additional spatial stream well. At 80 MHz, they can’t compete with the U6-LR and AC-HD.

Ideal for devices that communicate infrequently, the AP22 features Target Wake Time (TWT). By establishing a schedule for when clients need to communicate with an access point, it effectively increases device sleep time and significantly conserves battery life, a feature that is particularly important for mobile devices. I ran all of my tests with multiple TCP streams, and occasionally reversed the direction as a point of comparison. These tests ran for 60 seconds, so a typical client command would look like: iperf3 -c 172.25.10.5 -P 8 -R -t 60

Today, that is changing as Aruba introduces a new Wi-Fi 6 (802.11 ax) Access Point (AP) designed specifically with the needs of smaller organizations in mind. If you’re considering a new Instant On network, I have no issues recommending the AP22 over the AP11. I didn’t test the higher spatial stream AP12 or AP15, but those will have similar advantages that the AC-HD or U6-LR has. More spatial streams mean better multi-client performance, and usually better beamforming. The AP12 or AP15 should be better than the AP22 for high-density networks and in some scenarios, but I can’t say for sure. When their Wi-Fi 6 replacements arrive I’ll definitely be testing those. Beyond Wi-Fi 6, there’s also the promise of Wi-Fi 6E on the horizon, which is a more meaningful upgrade than the 10-20% speed improvement you can expect from upgrading from a good Wi-Fi 5 AP. Wi-Fi 6 and 6E are only relevant when you have clients that support them. Wi-Fi 6E devices are just starting to roll out in 2021, and it will be a while until it’s common for most home users. If you are happy with your Wi-Fi network, it could be a good idea to hold off on upgrading. If you’re looking for an upgrade now, the AP11 and AP22 are great options. OFDMA allows access points to handle multiple Wi-Fi 6 capable clients on each channel simultaneously, regardless of device or traffic type - improving efficiency and reducing latency. The AP22 is compatible with all your legacy wireless devices - 802.11b/g/n/ac - so you won't have to replace your smartphones and tablets.

Aruba Instant On AP22

I couldn’t get my MacBook Pro to associate to a 40 MHz channel on any of these APs, so I excluded those results from this test. I believe Apple uses the “ fat channel intolerant” setting on their devices. As always, 5 GHz is the best option for speed, and 40 MHz channels on 2.4 GHz should be avoided in most situations. Hospitality: Whether it’s a small B&B or the hottest boutique hotel in town, fast, secure, and reliable network access is the key to delivering an exceptional experience to guests and employees. The Aruba Instant On AP11D, AP12, AP22 and AP17 are great for spaces that require seamless indoor and outdoor access and coverage that provides a smooth in-room Wi-Fi experience. To specify which AP and which band was being used, I used the setttings offered in the UniFi network controller or Instant On portal, and swapped them in and out as needed. I then stepped through the different channel widths and bands, letting the connection stabilize before beginning my tests. The range difference between the AP22 and the U6-LR is big enough that it could be the difference between needing one or two APs to cover an area. In some situations one U6-LR is better, in others one or two AP22s may be better. It’s hard to make general conclusions.
