Aruba's 802.11n high-speed networks have also been deployed in the administrative offices of NHS Gloucestershire to support data access, wireless Voice over IP and guest connectivity. Prior to selecting a vendor for these sites, the Trust conducted an extensive technical review of single and multi-channel wireless LANs. Aruba's adaptive multi-channel Wi-Fi was more scalable, its Adaptive Radio Management (ARM) easier to deploy, and the network was more easily managed than competing systems. The network is supplied, installed and supported by Aruba Platinum Partner, Vanix.
