More than a decade ago, an EDN article examined the developments that paved the way for the wireless technology era. A March 4, 1993 feature entitled “Digital wireless networks” foresaw the existence of wireless LANs that could operate over infrared or RF channels and predicted that the Federal Communications Commission would allow various frequency-hopping and direct-sequence spread spectrum modulation schemes. Although it did not say anything about direct-sequence champion AT&T Microelectronics, the report mentioned Proxim, which advocated the frequency-hopping approach.
