带移动网络的背包

新华网2月27日电据科技博客Gizmodo文章，图中这款背包虽然外观低调，但内涵却不容小觑。它的内部组件可在10分钟内建立一个Ad-Hoc（点对点）模式的移动网络，非常适合在灾区使用。

这个巧妙的设计出自流动通讯网络公司沃达丰。这款背包重24磅，可作为手提行李登机。它可以在半径330英尺的范围内提供2G的GSM全球移动通信系统网，可支持同时拨打5个电话或同时发送数千条短信。

这款背包网络的重量和体积相比沃达丰以前的手提箱即时移动网络，都缩小了很多。手提箱即时移动网络重达220磅，可在3英里范围内提供即时网络，曾在去年用于菲律宾台风救灾，在29天的救灾时间中发送了140万条短信，拨打了443,288通电话。不过，新款的背包网络在便携性上取得了更大突破。

预计在未来世界范围的救灾工作中，这款新产品会大显身手。

This Network-in-a-Backpack Will Connect People in Disaster AreasThis backpack may not look much, but it has impressive hidden depths: it contains all the kit you need to establish an ad hoc mobile network in just ten minutes—perfect for those working in disaster areas.

Put together by Vodafone, the Instant Network Mini weighs 24 pounds and is small enough to be carried as hand luggage on commercial flights. It can provide a 2G GSM network which handles up to five concurrent calls—or thousands of text messages—within a radius of 330 feet.

It"s a far smaller version of the 220-pound, suitcase-sized Instant Network that Vodafone developed in the past. That has a range of 3 miles and was used during Typhoon Haiyan in the Philippines last year—carrying 1.4 million text messages and 443,288 calls in 29 days.

But that isn"t nearly as portable as this latest offering. Expect the new backpack to appear in disaster zones around the world as aid workers scramble to keep in touch.
