Flarion Technologies has successfully conducted its first field trial demonstrating the capabilities of its flash-OFDM (Orthogonal Frequency Division Modulation) system, a new wireless technology for the mobile Internet market.
The tests were conducted in the 700 MHz radio frequency band, for which Flarion has an experimental license from the US Federal Communications Commission (FCC). Flash-OFDM’s initial development began at Bell Labs three years ago. It was designed for mobile broadband access to the Internet and takes advantage of existing Internet Protocol (IP) and packet-switched technology.
Flarion claim that its new flash-OFDM system enables service providers to offer enterprises and consumers the speed of DSL and the mobility of cellular at the price of dial-up. One of the main benefits of the new technology is that different users within a cell do not interfere with each other.
What is more, unlike other wireless technologies like TDMA or CDMA, the OFDM receiver requires only a simple one-tap equalizer, making the system robust in the presence of delay spread and channel variations due to Doppler-shift.
Flarion is currently developing application specific integrated circuits (ASICs) that incorporate complete flash-OFDM baseband and RF functionality. The company intends to make the components available to its partners to promote the adoption of flash-OFDM.
