Wireless networks will be speedy

Microsoft, Nokia and a number of other major electronics companies claim to be perfecting the technology for wireless networks with data transfer rates of up to 6 Gbs / sec. Currently the average speed of wireless networks is only about 20Mbs / sec.

New technology is called Wigig (Wireless Gigabit), most likely to be completed by the end of the year and widespread in 2011.

With such data transfer rates, Wigig has outstripped existing wireless technologies. However, it uses a 60 GHz band, a high frequency type that often uses a network connection between rooms in the family.

Although the demand for high-definition video transmission in families is still small, it will certainly explode in the future. Accompanying is the trend of developing technology to connect TV with computers, video cameras, internet and other devices, because most consumers dislike the use of messy wires for real does the above work.

Wigig technology promises to improve wireless communication speed.


According to many manufacturers, along with the development of high-resolution video, Wigig's large bandwidth and low latency time are ideal for some applications, such as: playing games on HD televisions, extend your laptop's wireless connections to other devices, or help users stream videos from HD camcorders to TVs without cables.

Since Wigig is designed for the IP (Internet Protocol) protocol and is funded by Intel, Broadcom, Atheros and many other electronics firms, analysts think Wigig will go further than current wireless systems. .

Wigig does not compete directly with wifi

Another factor contributing to the sympathy for Wigig is that getting to merge it with wifi, or the Wigig technology, will not "treat" wifi-related devices before.

Currently, a faster version of the IEEE 802.11 standard using the 60 GHz band has been developed and the chip makers in the alliance have also mentioned Wigig as part of the tri-band wifi technology of 60 GHz, 2 , 4 GHz and 5 GHz.

Intel and Broadcom all hope Wigig will be an extension for Wifi. Both companies have relationships with the IEEE standard development team for the 60 GHz band (802.11AD). Evaluating Wigig's role, the IEEE team said: "This seems to be a complement to wifi."

Jason Trachewsky, Broadcom's chief technology officer and representative of the company in the alliance, said about Wigig: 'We don't call it wifi because it's not wifi. However, there are many similarities between them. A faster and low-latency wifi interface will be a great pleasure for our product line. '

Intel has planned to bring Wigig into My Wifi's chipsets, their Personal Area Network (PAN) technology launched late last year. My Wifi splits a client in a laptop or another device into two virtual clients. One is used to connect to a traditional LAN LAN network via point access while the other establishes peer-to-peer links with other devices.

Atheros semiconductor maker also found that Wigig is suitable for wifi networking technology across their Direct Connect and could even be a setting for a faster Bluetooth standard. Atheros' chief technology officer, Bill McFarland, hopes to see Wigig apply to its products before the 802.11AD standard is completed.

Thus, all three major chip makers hope for commercial chips attached to Wigig to appear in 2011, although before that, the standard needs to be completed, tested and certified. Broadcom's Trachewsky also has to admit: 'Everything is possible with plans'.

Wired communication still plays a role

However, no matter how the products attached to Wigig later hit the market, one thing is for sure, the wired protocols for transferring high-resolution content between rooms in a building remain. will exist.

According to Kurt Scherf, analyst at Parks Associate market analysis, these types of networks should be complementary to each other instead of competing with each other. According to Scherf and some other supporters of current systems, Wigig can be used to extend wireless home wiring like wifi is doing.

Wired technology still has a foothold even when wireless technology achieves higher achievements.


Scherf added: 'I think wired networks are still really needed. One reason is that most service providers do not want to provide support for a wireless system that often has instability '.

And Rich Nesin, chief executive of HomePNA, said wireless is not a good tool for reliable transmission and it lacks security (security).

Thus, the new Wigig wireless connection protocol seems appropriate to play a big role in the future of wifi, but it seems it won't jostle with other existing wired multimedia networks. .
