Aruba Receives FCC Approval for Software-Upgradable Access Points and Use of Additional 802.11n Radio Channels

Software Defined Radio Approval Allows Updates to Be Made via Software Download in Lieu of Hardware Replacement, Dynamic Frequency Selection Approval Makes Available Additional Radio Channels to Enhance Performance

SUNNYVALE, CA--(Marketwire - September 15, 2008) - Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in wireless LANs and secure mobility solutions, today announced that the Federal Communications Commission (FCC) has granted approval for Aruba to use Software Defined Radio (SDR) and Dynamic Frequency Selection (DFS) technology in its 802.11n access points.

SDR allows customers' access point radios to be modified and updated via software download over the network, without bringing the units out of service or even physically accessing them. DFS enables Aruba's wireless LANs to use otherwise prohibited 5.3 and 5.4GHz radar channels, thereby enhancing Wi-Fi bandwidth capacity. Upon detecting a radar transmission, DFS automatically shifts access points and clients to non-interfering channels. The SDR and DFS features are expected to lower customers' ongoing operating and maintenance costs, and improve network performance.

"Aruba is a pioneer in using software downloading to repurpose, update, and upgrade our wireless LANs, allowing them to evolve and deliver value long after the original purchase," said Keerti Melkote, Aruba's co-founder and chief technology officer. "SDR extends this concept down to the Wi-Fi radios. From the comfort of the data center, centralized IT staff can use SDR to update radios and add new channels. We believe this labor-saving tool will be hugely popular."

FCC rule 15.407(h)(2) requires that products support DFS when operating in the Unlicensed National Information Infrastructure (UNII) UNII 2 and UNII 2 Extended 5.25-5.35GHz and 5.47-5.725GHz bands, respectively. Devices operating in these bands must vacate restricted channels on which radar is detected, and are forbidden to enter the channels for a period of time after detection. The European Union mandates the use of a similar DFS scheme, and Aruba was recently granted approval based on the European EN 301 893 V1.4.1 standard.

"If enterprises determine that they must use DFS channels to meet the business goals of the application in the 5GHz band, then DFS provides a solution to address any interference issues, while a solid WLAN foundation ensures that unintentional interference will not cause intermittent issues," said Timothy Zimmerman, Gartner Principal Research Analyst.

"Bandwidth is king in an all-wireless workplace -- the more channels you have available, the greater the potential capacity of your network," continued Melkote. "DFS provides another 15 802.11n channels that can be layered together to add capacity, or switched to in the event of interference on other channels. Coming on the heels of European DFS approval, the FCC approval allows the use of DFS throughout our two largest geographic markets."
