Aruba Networks-An Adaptive WLAN Solution
Aruba Networks is a pioneer of Wireless LAN Technology.
Wireless LAN deployment allows 3 non overlapping channels out of the available 11 in the 2.4 GHz band and 8 non overlapping in the 5GHz band It is intuitive that the entire available bandwidth should be used in a deployment for better results. In this scenario Co-channel interference will be mitigated as there will be spatial distribution between same RF channels. RF management in this deployment model becomes complex. Aruba's ArubaOS with innovative Adaptive Radio Management features is the best optimized solution for this kind of deployment.
Another major issue which affects the scalability and performance in WLAN deployments is inter-cell handoff. In Aruba’s design, the handoff decision is distributed between the central Multi-Service Mobility Controller and end clients as well. This gives the best Mobility solution as the state vector of the endpoint and central switch will be in continuous synchronization.
Aruba’s VoWLAN solution for Seamless Mobility of Wireless phone calls between WLAN and Cellular Networks has several advantages. It can work with any of the solutions be it Carrier Centric, PBX-Centric or PBX-Agnostic. It uses Aruba’s application aware security and QOS mechanisms. It uses Aruba’s Remote Access Point solution to securely connect the Mobile Phones to enterprise services from home. It has a robust Call Admission Control, which works with any client and with any Codecs.
Voice over WLAN is a Voice over Net 2.0 application. Aruba has the best VoWLAN solution. So, Aruba is going to ride the VON2.0 wave.
Interview with Keerthi Melkote, Founder,Head of Products and Partnerships,Aruba Networks
VN: Compared to Wired Ethernet, WLAN is growing exponentially. ‘Desktop Gigabit Ethernet’, which was touted as the next big thing in enterprise networking has not seen much traction, whereas 802.11 deployments are into 4th generation with Aruba already deploying 802.11n. What is driving this growth?
Keerthi Melkote: The growth is being driven by social and economic forces that are making ours an increasingly mobile workforce. Mobility allows resources to be allocated and distributed as needed, and helps keep down costs by enabling virtual offices and teleworkers. The key is enabling mobile workers to remain securely connected to the enterprise.
VN: Will we continue to see such growth?
Keerthi Melkote: If anything the growth will accelerate as an economic downturn puts pressure on costs.
VN: Is Telephony (Voice and Video) the next killer application for WLAN Technology?
Keerthi Melkote: Voice, enterprise fixed mobile convergence (managed by the enterprise), and video look to be the next important applications.
VN: Do we see VoWLAN Deployments reaching critical mass very soon?
Keerthi Melkote: This is already happening in some industries and we expect the trend to continue.
VN: Are the benefits of Aruba’s architecture seen only in large deployments?
Keerthi Melkote: We address both ends of the spectrum. Aruba’s remote access point solution offers key advantages for individual users by allowing them to securely connect to the enterprise from home, on the road, hotels, or remote offices. Aruba’s Multi-Service Mobility Controllers are massively scalable, and can address the needs of the very largest enterprise that pervasively deploys high speed 802.11n networks.
VN: Do you have large scale deployments of personal Wi-Fi hotspots using the 3G networks? Can you offer this solution for maritime communities?
Keerthi Melkote: Please check for news on this in the coming weeks.
VN: Do you have a roadmap of Integrating WiMAX backhaul products for different verticals?
Keerthi Melkote: Our AirWave Wireless Management Suite already manages WiMAX networks, and we have published a white paper on integrating Wi-Fi and WiMAX networks – see http://www.arubanetworks.com/pdf/technology/whitepapers/wp_FIMAX.pdf
VN: Did you test the Call Admission Control in VoWLAN
Keerthi Melkote: We support CAC, yes.
