Following years of research and development, Nexion Data Systems believes it has found the right mix of technology and simplicity to permit high-speed data operation using conventional 2-way radio. Our management and engineering team stepped away from conventional chip solutions and standard data modulation schemes and concentrated on developing a modem using Digital Signalling Processing [DSP] technology. These commitments eventually lead to the NX1500 series our first generation modem employing advanced DSP algorithms and in-band audio signalling to achieve high-speed data transfer.
