Unsnarling that tangle of wires behind your home theater will be a task for the 60-GHz chipsets that perform the task wirelessly. Look for wireless audio, video and networking equipment by next year. R.C.J.
IBM and MediaTek Inc. will debut Tuesday (May 25) their 60-GHz transceiver chipset at the IEEE Radio Frequency Integrated Circuit Symposium in Anaheim, Calif.
The partners have been cooperatively developing the chipset for IEEE's Wide Personal Area Network standard which will replace that snarl of cables connecting video, audio and control signals among multi-media equipment. The transmitter chip had been previously described by IBM and Mediatek, but this is the first time they have described the receiver chip. The matched chipset is expected to be commercially available by next year. Because 60GHz signals cannot penetrate solid objects, they are confined to individual rooms. They also can interrupted by people or other objects in a room. To compensate, IBM and Mediatek have downsized military phased-array radar technologies to a single chip, allowing 60 GHz transmitters to steer the beam around obstacles between it and the in-room receivers to which signals are being routed...
