I'm currently working for a company that provides IT services to hospitals - I'm on the network engineering team. When I first arrived the team was so pumped about their Aruba set up, constantly bragging about the information available and functionality. I was taken by the constant complaining from the user base. Over the 3 years complaints have reduced dramatically, not because the experience has gotten better, but because people just gave up complaining.
I've been singing the praise of Ruckus for 3 years and we finally had a "bake off." Everyone agreed that the 200 APs in the hospital were not enough and that we really needed 300 - well, that is except ruckus - they did a full survey and said we could do the job (meeting capacity, speed and even VOIP requirements) with 75, but recommended 91 for redundancy. The hospital will be switched to Ruckus on Monday night, but we have already flipped 9 of our offsite locations and every one is reporting better service and higher speeds, with less APs. (As an example I just surveyed one of our sites that had 8 APs between the two floors. With Ruckus one AP fully covers the building at full speed. (It's an hour away from the office so the plan is to place 2 APs on site, one broadcasting, one not. So, in the event of a failure we simply turn on broadcasting for the second device and the site is back up in seconds.
One recommendation that I would make would be to purchase a light weight portable computer and something like Ekahau. Do a full survey before installing any wireless system. With Ruckus you'll be surprised just how much area an AP can cover and with their technology the performance will be amazing.
Full disclosure, I do not work for Ruckus, I have no affiliation with them, but they did give me on of the large plush dogs (after we placed the order) He's the talk of the office - often getting dressed up by someone. Oh, and I do consider Greg Kamer a friend.
