We use Aruba access points for enterprise and guest wireless.
We like the flexibility and the security, and the product is very easy to use.
I am not sure if it is a weakness, but Aruba sometimes redesigns Aruba Central and the web interface, which is sometimes an annoyance because you have to check everything all over again because the settings would have been placed somewhere else in the graphical interface, for example.
I have been using Aruba access points for eight years now.
The product is stable because sometimes security fixes are sent over email.
Everyone at our company uses Aruba access points. The product works for small, medium, and enterprise companies.
I have worked with Cisco, though not Cisco Meraki. I had no problems with that solution. My current company uses Aruba access points. Aruba access points are easier to deploy, and their pricing is on par with competing solutions. Moreover, you have more choices in the "flavors" of access points with Aruba, which is a plus point.
The solution is easy to deploy, and it normally takes three to five days. Of course, it depends on the customer's setup. Some customers need just five access points, while others require 14 switches and 50 access points.
It takes about a year before I get a return on investment because you need to place them. You get a return on investment when it comes to troubleshooting because you don't need to do as much troubleshooting on Aruba Central. If there are 50 sites, you do not need to check all of them. You have a larger return on investment over a longer period because it is easier to manage everything.
Aruba Central is a bit overpriced for some customers. It is expensive because you need to buy the hardware as well as the license. The license includes maintenance and support.
Before choosing Aruba access points, you should seek someone who is qualified or has done an introductory course to be able to use it. You will need to have some idea of how you want to arrange everything. Cisco Meraki has an introductory course, though I don't know if Aruba Central has one.
Though Aruba access points are priced the same as competitors, they should have discounts for more devices. If you have five devices, you pay the amount for five devices, but if you have 100 devices, it starts to get expensive.
I rate the solution a nine out of ten.
