http://www.soczigbee.com/dir1/wxss_zigbeerm.html

俺听了0:40听到现在还没听完~~~.

本来有本关于ZigBee的书,可是一直没时间看.

这次刚好边听边看~~~

 

听了3编2个半小时也没听懂~~~而且还没尾~~~不过俺知足了~~~

 

3:00了~~~8点去吴教授那里看看ZigBee长得是什么模样~~~

    ZigBee vs Bluetooth

    ZigBee is broadly categorized as a low rate WPAN, and its closest technology is Bluetooth.  A good bit of energy has been spent in analyzing whether ZigBee and Bluetooth are complementary or competing technologies, but after a quick look at the two, it can be seen that they fall a lot farther down the complementary side of the spectrum.  They are two different technologies with very different areas of application and different means of designing for those applications.  While ZigBee is focused on control and automation, Bluetooth is focused on connectivity between laptops, PDA’s, and the like, as well as more general cable replacement.  ZigBee uses low data rate, low power consumption, and works with small packet devices; Bluetooth uses a higher data rate, higher power consumption, and works with large packet devices.  ZigBee networks can support a larger number of devices and a longer range between devices than Bluetooth.  Because of these differences, the technologies are not only geared toward different applications, they don't have the capability to extend out to other applications.  As an example, for its applications, Bluetooth must rely on fairly frequent battery recharging, while the whole goal of ZigBee is for a user to be able to put a couple of batteries in the devices and forget about them for months to years.  In timing critical applications, ZigBee is designed to respond quickly, while Bluetooth takes much longer and could be detrimental to the application.  Thus, a user could easily use both technologies as a wireless solution in a PAN to suit all types of applications within that network.

    请问菜农：

    如果自己要学习ZIGBEE，要做哪些准备？

    有比较经济的办法吗？
