Export-Import Bank of Thailand taps Aruba for wireless connectivity

20 July 2009  |  1046 views  |  0 Source: Aruba Networks

Aruba Networks (NASDAQ:ARUN), a global leader in wireless LANs and secure mobility solutions, today announced that the Export-Import Bank of Thailand (EXIM) has deployed a high performance Aruba 802.11n network to securely enhance the productivity of its workforce.

EXIM was founded in 1993 and today has over 600 employees. The bank's legacy wired network limited employee mobility and collaboration. Following a needs assessment, it was determined that the network could be rightsized, eliminating all but the most essential wired connections in favor of high-speed 802.11n wireless connectivity. Being one of the first 802.11n networks in Thailand, EXIM conducted extensive due diligence prior to selecting a vendor. Several vendors were considered and subsequently eliminated due to cost, performance, and/or security concerns -- only Aruba's award-winning 802.11n solution addressed all three requirements.

"Like many other financial institutions, EXIM previously implemented a 'no-wireless' policy out of concerns about network security and privacy," said Khun Wanchai Teppichaiyanond, EXIM's Manager of Information Technology Operation and Communication Division. "We might still have that policy in place had we not been introduced to Aruba's identity-based security. Aruba's policy enforcement firewall, high security encryption, and network access control deliver security comparable to, or better than that used on our wired networks. The high speed 802.11n system gives our staff untethered, wire-like performance, allowing us to move forward with new efficiency initiatives that were predicated on having a mobile workforce."

Aruba's ICSA-certified policy-enforcement firewall provides identity-based security, Quality of Service control, and traffic management capabilities. The firewall classifies traffic on the basis of user identity, device type, location, and time of day, and provides differentiated access for different classes of users. Guest access to applications and resources, and even bandwidth consumed, are tightly controlled by the firewall and an integrated captive portal.

The wireless Mobility Controllers can authenticate users through Active Directory, RADIUS, LDAP and other commonly employed databases. Guest access can be tightly controlled with respect to bandwidth consumed and available applications and resources. The firewall allows network access policies to be precisely tailored based on the specific user, and to be consistently enforced regardless of where users work or roam.

To optimize 802.11n performance in real-time, ARM technology uses infrastructure-based controls to manage how Wi-Fi clients interact, and ensure that 802.11n data, voice, and video applications have sufficient network resources to operate properly. Acting on their own, Wi-Fi clients do not always work cooperatively with other clients, or select the optimal band, channel, and access point. These issues are exacerbated in environments like video-equipped conference rooms with high-bandwidth applications and densely packed clients.

ARM has been demonstrated to increase 802.11n throughput by more than 200%, enabling more than 100 laptops to reliably display multi-media lectures delivered from a single access point. An Aruba technical brief, 802.11n Client Throughput Performance, describing client field test results can be downloaded from Aruba's Web site at bit.ly/bMvT. ARM Yourself to Increase Enterprise WLAN Data Capacity, a new white paper outlining the technical features of ARM, is also available on-line at bit.ly/wFj9n.

"Our 802.11n network was easy to set-up and has required minimal on-going attention, a tribute to the automated features that keep the wireless services running at their best," continued Khun. "Our employees much prefer the freedom that comes from using a wireless laptop or PDA, and IT appreciates that this newfound freedom did not come at our expense -- the new system requires minimal IT overhead. Given EXIM's success, I'm confident that other financial institutions will follow suit and rightsize their wired networks."
