Aruba Receives FCC Approval to Use SDR, DFS Technology in 802.11n Access Points

Aruba Networks, a provider of secure mobility solutions, has received approval from the Federal Communications Commission to use Software Defined Radio and Dynamic Frequency Selection technology in its 802.11n access points.

According to the company, Software Defined Radio (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.

Aruba said that Dynamic Frequency Selection (DFS) enables the company'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.

Keerti Melkote, co-founder and chief technology officer of Aruba Networks, said: "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. 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."
