Panasonic Develops 60GHz Multi-Gigabit Wireless Circuit Technology for Mobile Devices Based on Major Wireless Standards

Business Wire
Panasonic Corporation has successfully developed a 60GHz
multi-gigabit wireless communication technology that is optimized
for mobile devices, and supports the WiGig [1] specification and/or
the IEEE802.11ad [2] draft specification. This multi-gigabit
wireless communication technology consists of a 60GHz transceiver
and a baseband processor which are integrated individually onto
CMOS semiconductor chips through circuit technologies optimized for
mobile devices. The technology enables multi-gigabit wireless
communication of more than 20 times faster than existing wireless
LANs using the 60GHz frequency band, and through the optimization
of both the transceiver core and peripheral circuits, it also
enables lower than 1W low-power, multi-gigabit wireless
communication in the future.
Up till today, only the 2.4GHz and 5GHz bands have been used in
high-speed wireless communication for mobile devices while 60GHz
ultra-high-speed wireless communication remains to be employed only
in stationary devices such as TVs, but not in mobile devices due to
the higher energy consumption associated with the use of wider
frequency bandwidth.
With high-speed communication of 20 times faster than existing
wireless LANs, this technology allows the transferring of a
30-minute long compressed high definition (HD) video content within
10 seconds. In combination with the low power features made
possible through the transceiver core and peripheral circuits
optimization, it has been made viable for mobile devices such as
smart phones that requires lower than 1W of power consumption in
their radio function unit. This is a big step forward to realize
stress-free, fast HD video content transfer and streaming on mobile
devices.
The technology has the following features:
1. 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.
2. 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.
3. 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.
The technology consists of the following new Panasonic’s
technologies:
1. A unique multiband voltage controlled
oscillator technology, which achieves excellent phase noise while
covering over 9GHz frequency bandwidth required by the WiGig
specifications.
2. 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.
*Based on Panasonic data as of June 2, 2011
[1] Wireless Gigabit Alliance was established by technology
leaders within the consumer electronics, personal computer,
semiconductor and handheld industries to address the need for
faster, wireless connectivity between computing, communications and
entertainment devices. Panasonic has been a board member of WiGig
Alliance.
[2] The IEEE802.11 is a Working Group that defines a set of
standards for Wireless Local Area Network. The Task Group
IEEE802.11ad has developed a draft standard specification for next
generation high speed communication of above 1Gbps in the 60GHz
frequency band.
