US : Military Communications Technologies, Inc. announced that its Australian-based affiliate, Military SDR Technologies, has successfully implemented an OFDM waveform on its SpectruCell and PC4 Software Defined Radio platforms.

OFDM, orthogonal frequency division multiplexing, is a telecommunications technology that is the foundation of most next-generation, or 4G wireless Internet services for high speed data transmissions at comparable rates to fixed DSL services. OFDM transmits multiple signals simultaneously over a single wireless system.

This successful implementation of the OFDM waveform is the first step in Military SDR Technologies plan to implement the complete IEEE 802.16 family of wireless data applications, also known as WiMax, a higher performing version of WiFi. Emerging as the predominate technology for providing cost-effective, high-speed wireless Internet solutions, WiMax capabilities compare to traditional land based DSL services in terms of speed and cost, with the added capability of wireless mobility. WiMax-based services will be capable of delivering high quality voice, video and multimedia content over an Internet-based connection.

"The implementation of OFDM is an important milestone for our company," stated Mr. Roger May, Chairman of Military Communications Technologies. "Leading wireless service providers, particularly those based in Asia, are trending towards OFDM-based wireless technology, as it provides for a simpler and much more cost effective alternate to competing wireless technologies such as wideband CDMA ("3G"). Market studies indicate that the North American-based and global wireless carriers generally are also following this trend and we anticipate being the first to provide an OFDM SDR solution for simultaneous support of both 3G and 4G applications in both the commercial and defense sectors for wireless communications", concluded May.
