A team of Korean scientists has developed advanced technology dubbed binary code division multiple access (CDMA), which they say is better than Bluetooth for short-range wireless data transmission. It allows devices located hundreds of meters away from each other to remain connected. With terminals equipped with binary CDMA chips, transmission of digital picture files is possible at a distance of 500 meters wirelessly without the help of a base station. Functionalities of the binary CDMA are similar to those of the widely-used Bluetooth but its service range and capacity are much better than the latter. Our binary CDMA technology has a peak speed of 55 megabits per second, much faster than Bluetooth. Its wide service range of 500 meters is also unrivaled. The chip prices are expected to be higher than those of Bluetooth, but mass production will reduce the difference.
