Wi-Fi Infrastructure
Unstrung reports that that under new rules for Software Defined Radios set by the FCC, Cisco's 802.11a radios will be the first to be certified as SDR Wi-Fi products.
Cisco's Aironet 1240AG http://www.cisco.com/en/US/products/ps6521/products_data_sheet0900aecd8031c844.htmlaccess points currently provide 12 operating channels in the three 5GHz Unlicensed National Information Infrastructure bands, but will soon be field upgradeable to support an additional 11 channels between 5.4 and 5.7GHz. That would nearly double their available network capacity.
The current 1240AG radios, using the 5GHz band, can be upgraded in the field.
"This use of the FCC's progressive Software Defined Radio regulations provides real value to enterprise customers today who are continually calling upon their wireless networks to support more bandwidth intensive applications," said Brett Galloway, vice president and general manager, wireless networking business unit at Cisco Systems.
Future SDRs will be capable of dynamically switching across a wide range of frequency bands, transmission techniques and modulation schemes so that a single radio could take the place of multiple hardware designs. For example, a user device with a single SDR could be capable of automatically switching between Wi-Fi, Wi-Max, GSM and CDMA networks.
