'next generation' wi-凯发k8官网

the next-generation of wi-fi technology has finally been approved for use, despite being on sale in laptops and other equipment for several years.

下一代wi-fi技术最终被核准使用，尽管已经在笔记本和其他设备上销售了好多年。

manufacturers have been selling 802.11n products for many years

the 802.11n technology, as it is known, was ¹ by the ieee, a body that ² all wi-fi standards.

it was conceived（构思，怀孕） seven years ago and offers speeds at least six times faster than current approved technology.

electronics firms have sold pcs and routers using the standard for many years, labelled "802.11n draft".

but without the ieee's approval, there were no guarantees that future networking equipment would be compatible with the devices.

the ieee's rubber stamp（不经审查就批准） has changed that.

all existing draft 802.11n wi-fi products will work with the final standard, according to the wi-fi alliance, a group that tests ³ products to ensure compliance（承诺，顺从）.

"this was an ⁴ wide-ranging technical challenge," said bruce kraemer of the ieee.

"when we started in 2002, many of the technologies addressed in 802.11n were university research topics and had not been ⁵（应用的）."

under ideal conditions, 802.11n technology can offer speeds of 300 megabits per second (mbps) and above, many times higher than the previous 802.11g, which operates at speeds of up to 54 mbps.

it is also able to transfer data over distances of 90m (300ft) indoors, double that of previous technologies.
