求zigbee大神翻译下面的英文原文
In-Your-Face Communication
To save as much power as possible, ZigBee employs a talk-when-ready communication strategy, simply sending data when it has data ready to send and then waiting for an automatic acknowledgement. According to Bob Heile, who is chairman of both the ZigBee Alliance and IEEE 802.15, talk-when-ready is an "in-your-face" scheme, but one that's very power efficient. "We did an extensive analysis that led to the best power-saving strategy in various kinds of environments from quiet to noisy," Heile says. "We discovered that, hands down, we were better off just sending the packet and acknowledging it. If you don't get an ack, it just means you got clobbered, so send it again. You wind up having much better power management than if you listen and determine if it's quiet before you talk."
Fortunately, this in-your-face strategy leads to very little RF interference. That's largely because ZigBee nodes have very low duty cycles, transmitting only occasionally and sending only small amounts of data. Other ZigBee nodes, as well as Wi-Fi and Bluetooth modules, can easily deal with such small, infrequent bursts.

答案和解析
为了尽可能节省电力,ZigBee采用一个说话的时候准备好的沟通策略,简单地发送数据时,数据准备发送,然后等待一个自动确认。根据鲍勃航空航天,谁都是ZigBee联盟和IEEE 802.15董事长,说话的时候准备是一个“在你脸上”的方案,而是一个非常有效的权力。”我们做了一个广泛的分析,LED的最好的节能策略在各种环境安静吵,”航空航天说。”我们发现,手放下,我们最好只是发送数据包并承认它。如果你没有获得确认,它只是意味着你有了,所以把它再次。你会有更好的电源管理比如果你听并确定它是否是安静的在你说话之前。”
幸运的是,这种当面策略导致非常小的射频干扰。这主要是因为ZigBee节点具有非常低的占空比,只偶尔传输发送少量的数据。其他ZigBee节点,以及Wi-Fi和蓝牙模块,可以轻松地处理这样的小的,罕见的爆发
