Development of Multi-Gigabit Wireless Communication Technology for 60GHz frequency Band by Panasonic
Panasonic has announced the successful development of a 60GHz multi-gigabit wireless communication technology supporting WiGig specification as well as IEEE802.11ad draft specification. The new multi-gigabit wireless communication technology which is optimized for mobile devices consists of a 60GHz transceiver and a baseband processor that are integrated individually onto a CMOS semiconductor chip via circuit technologies.
The new technology is capable of wireless communication which is 20 times faster than the current wireless LANs using 60GHz frequency band. Use of 60GHz frequency band up to now has been limited to stationary devices such as TVs, due to the higher energy consumption associated with use of wider frequency bandwidth; however Panasonic by optimizing both the transceiver core and peripheral circuits has achieved a power consumption of less than 1W, ideal for mobile devices such as smartphones requiring less than 1W of power consumption in their radio function unit, paving a way for fast HD video content transfer and streaming on mobile devices. Some of the key features on the newly developed technology are its industry’s lowest noise signal generator of -95dBc/Hz at 1MHz offset frequency, enabling a high sensitivity wireless performance, forward error correction code for maintaining a reliable high-speed wireless communication. Furthermore, integration of the transceiver into the CMOS would result in more compact mobile devices. The new technology inherits several new Panasonic’s technology including a unique multiband voltage controlled oscillator technology as well as a Forward Error Correction (FEC) decoding circuit technology.
