the world of wi-fi is to become a whole lot easier thanks to a major technology upgrade, says an industry group.

industry watchers say wi-fi direct could have far-reaching implications

the wi-fi alliance said it would soon finish work on a new ¹ called wi-fi direct.

it will let wi-fi devices like phones and laptops connect to one another without joining a traditional network.

the wi-fi alliance - whose members include intel, apple and cisco - hopes devices with the new technology will be on the market by the middle of 2010.

owners of devices without wi-fi direct will be able to upgrade through a software download, says the technology consortium（联合，合伙）.

the wi-fi alliance's ² director, kelly davis-felner, told bbc news: "this is going to be a quick and convenient way to use wi-fi in future to print, synch（同时，同步）, share and display.

"the consumer is going to experience this as a very easy-to-use ³ that will be quite seamless（无缝的）."

threat to bluetooth?

wi-fi direct will automatically scan for local existing hotspots and any wi-fi-enabled devices, such as cameras, phones and computers.

the alliance says the specification will search for both consumer electronics and office applications, enabling devices to connect from across a home or workplace.

victoria foote, senior ⁴ at in-stat, said it was a "terrific innovation".

ben parr, co-editor of mashable.com, told bbc news the potential impact could be far-reaching.

but industry watchers also say the technology could pose a threat to the future of bluetooth and perhaps do away with the need to use wi-fi routers in some places.
