My relationship with Aruba Remote Access Points is that if the consultant specifies the HP Aruba one, then the customer goes with that specification and recommendation. Based on my experience as a technical expert, both Cisco and Aruba Remote Access Points deliver the same results.
There are a few differentiations, but in my opinion, as a technical professional, only the name and physical size differ. Both are meeting customer expectations, especially under firewall management and broadband management systems, with an emphasis on high-security applications. Normal access control doesn't limit or block any traffic; all these tasks are managed by firewalls. In Sri Lanka, we use access points below 23 dB indoors, while over 23 dB is for telecommunications providers.
When planning implementation, we have to consider surrounding equipment, as wireless means dealing with EMF signals. Knowing the behavior of EMF signals is crucial instead of just having high-end access points; placement and installation are key to maximizing the effectiveness of these devices. Otherwise, increasing the power level might not provide the proper signal and can create interference.
