The peanut butter cup approach to technologyCDMA - Short for code division multiple access, CDMA is a digital cellular technology that uses spread-spectrum techniques. Rather than assigning a specific frequency to each user, every channel uses the full available spectrum instead. Wi-Fi - Short for wireless fidelity and meant to be used generically when referring to any type of 802.11, Wi-Fi refers to a family of specifications for wireless local area network technology.

Engineers are always making us choose between technology formats. Why can't they take the peanut butter cup approach instead: Put the peanut butter inside the chocolate, and give us the best of both? ExaDigm Inc. has done just that. The company announced a single modem enabling its XD2000 mobile POS terminal to use either Wi-Fi or cellular Internet access. The CDMA/Wi-Fi modem for the XD2000 is said to be a first for the POS industry. It does away with having to carry two separate modems and enables merchants to switch from cellular to Wi-Fi and vice versa with a few keystrokes. The modular design gives merchants the convenience of choosing virtually instantaneously the wireless connectivity that best meets their needs in a transaction situation. The dual-technology modem is especially useful for mobile merchants moving between environments where wireless connectivity options change. In areas with strong Wi-Fi coverage, merchants using cellular will be able to switch over to Wi-Fi for better connectivity and reduce usage costs on their cellular data plans. For those areas where Wi-Fi is not available, merchants can rely on code division multiple access (CDMA) cellular service to process transactions. "In the POS cellular space, we need to remember that we're not driving change; we're just along for the ride," said Michael Mulcahy, ExaDigm's President and Chief Operating Officer. By delivering an advanced solution, the company is helping merchants adapt to evolving technology. So mobile merchants: Carry just one modem, but pack extra peanut butter cups. ExaDigm Inc. |
