As companies scramble to develop 3G telephony and data services, the need to acquire additional radio spectrum has become a pressing issue. The efficiency of modulation technologies is increasing also but slower than demand.
GCM/OTDM solves this problem by reducing the amount of allocated spectrum required to transmit data. GCM/OTDM has a higher efficiency so it can reduce the required spectrum by up to 10 times without changing current hardware platforms.

Since the BER and noise susceptibility performance is excellent, our GCM/OTDM DSL application should use up to 24dB less power than ADSL systems to reach the same rate. This translate to longer battery life and longer range networks for wireless systems

The company has jointly developed a working hardware design for the DSL market and it soon will be a product increasing more than a 200% the area of coverage for broadband services, reducing up to 24dB the transmission power and increasing the rate up to 32Mbps in the same bandwidth of ADSL2+. The modulation and demodulation circuitry can be integrated into FPGA or ASIC and will be integrated into equipment such as computers, TV's, phones, cell phones, base stations, etc. Actually, the company is developing a hardware for the wireless market with the goal of reaching over 300Mbps in the 2.4GHz/5GHz band.

GCM/OTDM is relatively easy to integrate in any current communication system or application as it does not modify any physical RF nor baseband parameters. Specially for UMTS or CDMA systems, a change in the firmware of base stations is enough to increase the rate of physical layer, reducing power or the number of basestations needed to cover a given area. Obviously, terminals will also have to be modified to add this features.
