60GHz device supporting WiGig and IEEE802.11ad
specs developed by Panasonic
Panasonic Corporation has developed a 60GHz multi-gigabit
wireless communication technology that is optimized for
mobile devices, and supports the WiGig specification and/or
the IEEE802.11ad draft specification. This multi-gigabit
wireless communication technology consists of a 60GHz transceiver
and a baseband processor, which is integrated individually
onto a CMOS semiconductor chips through circuit technologies
optimized for mobile devices. When wireless LANs operates
using these 60GHz semiconductor devices, the speed is 20
times faster than existing wireless LANs.
The features of this technology as per Panasonic includes:
The world's lowest noise signal generator (-95dBc/Hz at
1MHz offset frequency) enables high sensitivity wireless
performance. The transceiver has been integrated into a
CMOS chip, which leads to miniaturization of the mobile
devices.
Forward error correction (FEC) code is indispensable to
maintain reliability in high-speed wireless communication.
In this technology, the circuit size of decoding block is
30% smaller than that of Panasonic's conventional architectures
by optimizing decoding circuits. This reduction results
in lower power consumption.
The chipset supports the WiGig specification, which is going
to be an industry standard for a multi-gigabit, short range
wireless communication system. It will provide reliable
interoperability among various devices.
A unique multiband voltage controlled oscillator technology,
which achieves excellent phase noise while covering over
9GHz frequency bandwidth required by the WiGig specifications.
A FEC decoding circuit technology, which enables the use
of common functional units to handle various error correction
codes specified in the WiGig and at the same time achieves
low power by reducing the circuit complexity and the operation
frequency.
On this development, Panasonic holds 16 domestic patents
and 16 overseas patents, including pending applications.
This development will be presented at ICC 2011 (International
Conference on Communications 2011) to be held at the Kyoto
International Conference Hall, Japan from June 5 to 9, 2011.
This new technology was partly supported by "The research
and development project for expansion of radio spectrum
resources" of The Ministry of Internal Affairs and
Communications, Japan.
