È ormai da qualche anno disponibile la connessione Gigabit Ethernet per pc desktop e notebook: questa connessione, che come dice il nome stesso funziona a 1000Mbit/sec, permette di trasferire grandi moli di dati in breve tempo. Con la crescita esponenziale di dispositivi wireless e con la crescente domanda da parte dell’utenza di dispositivi semplici da configurare e con la minor quantità possibile di cavi da collegare per avere piene funzionalità, si è reso necessario un aggiornamento degli standard wireless (che ha portato allo standard IEEE 802.11n nel 2009) che permettesse alte velocità di trasferimento. Lo standard IEEE 802.11n tuttavia permette velocità di comunicazione reali fino a 72,2Mbits/sec (150Mbits/sec nel caso di canali da 40MHz di ampiezza), certo non comparabili con le velocità raggiunte nelle connessioni via cavo. È qui che entra in gioco lo standard WiGig : operante sulle frequenze dei 2.4, 5 e 60GHz, lo standard permetterà di raggiungere velocità fino a 7Gbit/sec, oltre 10 volte più veloce della migliore connessione consentita dallo standard IEEE 802.11n. Simili caratteristiche ha lo standard 802.11ad, che si presume verrà finalizzato nel 2013.
Panasonic ha presentato una radio per smartphone di fascia alta e dispositivi portatili che sfrutta una connessione a 60GHz su standard WiGig e/o 802.11ad. La compagnia ha dichiarato che il consumo del chip è di un solo Watt. Ci vorrà del tempo prima di vedere implementate queste meraviglie tecnologiche sui nostri dispositivi, ma nel frattempo possiamo goderci l’attesa sapendo che prima o poi potremo gustarcele anche noi.

OSAKA, Japan–(BUSINESS WIRE)–Panasonic Corporation has successfully 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 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.

 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.
 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.
Panasonic Corporation is a worldwide leader in the development and manufacture of electronic products for a wide range of consumer, business, and industrial needs. Based in Osaka, Japan, the company recorded consolidated net sales of 8.69 trillion yen (US$105 billion) for the year ended March 31, 2011. The company’s shares are listed on the Tokyo, Osaka, Nagoya and New York (NYSE:PC) stock exchanges.
